Elbit Systems to Supply Power Amplifiers for the F-35 Lightning II Aircraft
March 11, 2020
Elbit Systems of America has been selected by Cubic Mission Solutions to design and develop the Full Motion Video Data Link (FMVDL) amplifier module for the communications suite of the F-35 Lightning II aircraft. The amplifier module is a critical component of increasing the aircraft's advanced sensor suite by providing enhanced situational awareness to both airborne and ground forces. The F-35 FMVDL modules will be designed and manufactured at Elbit Systems of America in Fort Worth, Texas.
Joel Friederich, Vice President of C4I & Homeland Security Solutions at Elbit Systems of America commented that this selection demonstrates Elbit America's reputation as a leader in providing innovative airborne amplifiers for military tactical communications. The F-35 full-motion video amplifier modules provide the power behind the F-35's integrated communication/data link system and enable warfighters to have full situational awareness while boosting the 5th generation combat capability of the aircraft.
Building off its legacy of airborne amplifiers, Elbit Systems of America's solutions significantly boosts power for the F-35 communication suite, while reducing the unit's size. These aspects enhance the ability of the aircraft to send and receive critical information, thereby extending situational awareness from one aircraft to an entire network of warfighters, whether they're airborne or providing ground operations.
To date, Elbit Systems of America has supplied a variety of components for the F-35, from the UHF/VHF power amplifier, to the panoramic cockpit displays, to the unprecedented F-35 Helmet Mounted Display System.

Cubic and Full Motion Video Link Within the CNI F-35 System
SAN DIEGO – June 11, 2019
Cubic Corporation today announced that its Cubic Mission Solutions business division was selected by Lockheed Martin as the Video Data Link (VDL) provider for the F-35 Lightning II Program. Cubic’s VDL capability for the F-35 will significantly increase the aircraft’s combat capability and is an essential capability to the overall F-35 follow-on modernization program.
“We are very pleased to partner with Lockheed Martin to provide a secure video data link capability for the F-35,” Mike Twyman, president, Cubic Mission Solutions. “Our team of protected communications experts have decades of experience supplying common data link systems and we look forward to partnering on this critical program.”
“With our proven track record of managing a program from development through fielding, along with the proven performance of our software-defined radio products including the Nano Multi-band Miniature Transceiver, we are confident in our ability to deliver a low-risk, cost-effective Video Data Link solution with built-in life cycle enhancements,” said James Parys, program director, Cubic Mission Solutions.
Cubic’s offering is a secure and mission-enhancing system that easily fits within the allocated Communications, Navigation and Identification (CNI) subsystem volume. The software-defined, radio-based VDL solution features high-performance processing that can support future live video enhancements, while minimizing size, weight, power and cooling (SWAP-C). Cubic’s solution enables the F-35 to transmit and receive sensor and metadata to and from multiple ground or airborne units.
And on March 1, 2020, it was announced that Elbit has been chosen to design, develop and manufacture the Full Motion Video Data Link (FMVDL) amplifier module for the communications suite of the F-35 Lightning II aircraft.

We can add the following to this Cubic White Paper based on interviews we have conducted with two members of the Cubic Mission systems team.
In an interview with Vice President and General Manager Bradford Powell, Cubic Corporation’s C2ISR Solutions business, he discussed FMV’s enhanced role within the evolving C2 and ISR infrastructure for the integrated distributed force.
According to Powell, the clear trend line is toward significantly expanding access to imagery and FMV while improving integration between the two:
“We are working to provide context within the full motion video feeds, which will enable the operational user to make tactical decisions more effectively.”
Powell described C2 as moving from a focus on maps to command and control operating from within full motion video. Such focus will require tools that provide context easily used by the tactical decision maker.
As a relatively simple example, Powell referred to how television networks superimpose yellow first-down markers over the video of a football game. Imagine, then, the various data clusters which could be laid down over the full motion video available to the tactical decision maker in his area of interest or the area where he is operating, and one can envision the coming future of video-driven context for C2 at the tactical edge.

The task is to insert relevant tactical data into the full motion video.
“The full motion video–focused C2 environment would thereby evolve to make a broader set of intelligence products discoverable in the video.”
The overall focus is to give the local decision maker much greater context for what he is looking at in the full motion video.
Cubic’s input into the CNI system will allow the F-35 to evolve along the lines suggested by Powell.
James Parys at CMS, the man responsible for the teams working the new CNI capability into the F-35, who is the Director of Platform Communications Programs for Cubic Mission Solutions, a business division of Cubic Corporation provided further details on the Cubic engagement in CNI. Mr. Parys has more than 25 years of experience in program management and business development in the defense, information technology, and computer science industries.
Parys began his career in the U.S. Navy and, after leaving the service, has worked in industry on a variety of C2 and ISR programs.
In his current role, he manages Cubic’s platform-focused communication system program organization, which includes the F-35 Joint Strike Fighter and MQ-25 Unmanned Carrier-Launched UAS Video Data Link (VDL) programs for CMS.
As a combat system, the F-35 allows for significant upgrades over time, which is why some commentators’ notion about the F-35’s obsolescence makes little sense when one considers the aircraft’s built-in software and related hardware upgradability.

According to Parys, “We’re providing a set of cards that will integrate into our own segregated element of the CNI rack. It’s basically going to be, for lack of a better term, a rack inside a rack.
“We will take video feeds from other very complex sophisticated sensors onboard the aircraft and communicate informationto other users, whether they’re on other aircraft or on the ground, which they can leverage. Our data link’s primary CONOPSis to support close air support.”
Cubic has developed the ability to put into cards what once took up a lot of real estate and power generation to process the data and then communicate. Cubic is putting technology inside the F‑35 that is battle-tested and matured within other systems operating in the battlespace.
The data fusion on the aircraft is unique and also leverages proven technologies in step with modernization of the CNI function on the aircraft.
In other words, Cubic is harvesting their experience elsewhere and putting it on the F-35 as the aircraft matures and evolves.
They will be able to harvest some of those solutions to benefit universal enhanced capability for an ISR C2 integrated infrastructure, which is evolving for the overall force development of the integrated distributed force.
A key element of the new capabilities Cubic is providing for the F-35 is an ability to pass over the middleman, or to reduce the need to send the data to a processing center which, in turn, sorts through the data and then sends it out to the user.
Cubic is significantly reducing what one might call the tooth-to-tail relationship in the C2 and ISR infrastructure.

Parys said, “We are supplying data directly from the F-35 to the ground combat elements that have not had access to before.
“We will provide very-high-resolution information coming off the F-35sensors directlyto the ground forces.
“With our solution, we’re leveraging other capabilities, such as ISR Processing, Exploitation, and Dissemination (PED)–type capabilities to be able to clean up the video, and enable higher levels of resolution and higher contrast.
“By that I mean, being able to clear fog or see through smoke and share that view to the troops down on the ground, rather than the data having to be back-hauled to a PED station somewhere.
“The troops on the ground receive that data directly, which helps them make better, time-urgentdecisions.”
Effectively, this capability contributes to building an infrastructure that connects the ground combat element to the aircraft’s systems.
The modernized CNI takes abundant visual data and transforms it to shape a more usable data stream that supports combat operations.
Parys added, “We aregoing to reduce the whole timeline of the mission and what they need to do.

“This information can be sent to other aircraft; it can also be sent to other ground units.
“It means taking this advanced sensor in the sky and making its information available for whoever needs to leverage it and use it, whatever their mission is.
“The information will be available at an enterprise level rather than be limited to the traditional single stakeholder to single stakeholder process.”
I have argued elsewhere that one advantage of the F-35 global enterprise for defense companies, and not just the prime contractor, is to provide global users with the experience of working with a variety of companies they might not have experienced before.
This certainly is the case with Kongsberg and its F-35 Joint Strike Missile (JSM), which additionally has led to broader understanding of what their technology can provide to other combat elements.
This was demonstrated when the U.S. Navy adopted a Kongsberg strike missile being coproduced with Raytheon.
A similar positive outcome is predictable for Cubic and its engagement on the F-35.
As users become familiar with innovative processes of incorporating full motion video into a decision-making flow, we will see a demand to replicate such experiences elsewhere for other combat forces.
Parys highlighted: “We’re taking what we’re putting on the F-35 and we’re making it even smaller; fully packaged, but even smaller, and we’re putting it in the hands of users on the ground as well.”

The Impact of Advanced Fusion in 5th Generation Fighters on Combat Capability
26 Oct 2013 Michael Skaff, [Lead PVI Designer] Lockheed Martin Aeronautics Company

"...Providing for Decision-Making Tools [from dat shed?]
5th generation advanced sensor fusion is more than a fused and correlated picture of battlespace. The fusion engine controls the sensors and tasks them automatically to fill in data and combat identification holes. As each sensor reports kinematic and identification data, the fusion engine notes the data that is missing or data that would be better reported from a different sensor.

For example, a high resolution scanning infrared search and track system may report extremely accurate azimuth and elevation data, but poor or no range data. The radar, on the other hand, may report fair angles and very accurate range. Fusion will task the radar to stare along the IRST line of sight to measure the range.

Fusion then combines these two sensors into a “best features” kinematic solution. Fusion does this for every track and every sensor, as appropriate. Automatic sensor tasking occurs in the background and without pilot involvement.

Advanced sensor fusion goes beyond the ownership of a single cockpit. It is part of a fleet. It connects in order to communicate with the other fusion engines through a high speed network. This affords tremendous synergy as 5th generation fighters operate together in a connected OODA loop sharing sensor information. The pilots all see the same picture on their tactical situation displays. As an individual airplane builds the picture, it is shared with the other fighters on the network.

Don’t misunderstand, we don’t share the graphical picture – we share the fusion contents in such a manner that each participating fusion engine can build its own graphical depiction for the pilot. In similar fashion to how fusion uses the best data from each sensor to build a better kinematic and ID solution it also uses every other fusion engine’s contribution to do the same thing.

Why is this important? Here is a simple example.
Suppose the enemy is able to attack and defeat a sensor on one aircraft. Fusion will exclude data from that sensor and use another sensor or even another aircraft’s fusion results. The chances of the enemy being able to attack and defeat every sensor on every connected 5th gen fighter at the same time are almost impossible.

The synergy of connected fusion engines is one of the hallmarks of the 5th generation…."

Re: APG-81 vs ASQ-239

Description about F-35 EW.

http://www.airdominance.nl/index.php/aircraft-f35.html
ASQ-239 "Barracuda"
The AN/ASQ-239 “Barracuda” is an integrated Electronic Warfare (EW) and self-defense system. It is able to operate not just with other components within the aircraft such as the APG-81 but it can also operate with other F-35’s over MADL to perform EW operations together.
It’s able to precisely geo-locate emission locations hundreds of kilometers away, further then it’s radar can see and from there the APG-81 can be slaved to that data track and then detect and track the object with a very narrow beam, increasing power and detection on target while decreasing detection by other aircraft.
At close range or against targets using Jammers it is capable of narrowband interleaved search and track, which provides precise range and velocity that can then be used to shoot a missile without the need of the APG-81, allowing a 360 degree sphere of targeting other aircraft.
The Barracuda can refer to its data-banks of known emissions and identify the source vehicle or store it for future classification. Other features are false target generation and range-gate stealing, offensive EW is possible, a towed RF decoy is also a part of the package as is a MJU-68/B Flares system.

O’Bryan said the power of the F-35’s EW/EA systems can be inferred from the fact that the Marine Corps "is going to replace its EA-6B [a dedicated jamming aircraft] with the baseline F-35B" with no additional pods or internal systems.
Asked about the Air Force’s plans, O’Bryan answered with several rhetorical questions: "Are they investing in a big jammer fleet? Are they buying [EA-18G] Growlers?" Then he said, "There’s a capability here."
O’Bryan went on to say that the electronic warfare capability on the F-35A "is as good as, or better than, [that of the] fourth generation airplanes specifically built for that purpose." The F-35’s "sensitivity" and processing power—a great deal of it automated—coupled with the sensor fusion of internal and offboard systems, give the pilot unprecedented situational awareness as well as the ability to detect, locate, and target specific systems that need to be disrupted.
When it comes to electronic combat, the F-35A will make possible a new operational concept, O’Bryan said. The goal is not to simply suppress enemy air defenses. The goal will be to destroy them.

http://vanguardcanada.uberflip.com/i/30 ... l-may-2014 (page36-37)
For starters, the F-35’s APG 81 radar is no longer just a radar.
“It’s a multi-functional array” that automatically fuses information from “thousands of radars” in the aircraft, O’Bryan explains.
And rather than the familiar sweeping cone, the F-35’s beam is more like a laser, able to focus on a specific target or on multiple targets (the exact number is classified) with ten times the power of an EA 6B Prowler, he says.
Furthermore, a formation of four F-35s can alternate transmission of the jamming signal among themselves, again automatically.
And with stealth capability, one or all four of the aircraft can operate from inside the target’s firing range.
“You start with 10 times more power, and if you are much closer and you are alternating signals between four airplanes with a stealth data link between them, you can do that jamming in a coherent, cooperative manner.
The signal, the technique, everything is done for [the pilot].”
Equally important, where fourth generation radar are able to detect the arrival of a threat with plus or minus 30 degrees accuracy, the F-35 can pinpoint the threat to within plus or minus one degree, an advantage that is narrowed further with the assistance of a formation of four aircraft sharing that threat trajectory, he says.

http://www.airforcemag.com/MagazineArch ... rness.aspx
Col. George M. Reynolds, commander of the 55th Wing, which counts the EC-130H and RC-135 fleets in its portfolio, explained that the EC-130 offers several main capabilities. Those are “countercommunications, counterradar, counterdata, and counternavigation,” he said in an interview.
“We do a full range of military operations, from supporting small teams on the ground all the way up to the high-end conflicts,” he explained. The EC-130 can perform standoff communications or radar jamming of enemy air or surface craft. It can listen for enemy communications, warn troops on the ground that an enemy is nearby, or disrupt the enemy’s attack at selective moments by jamming, Reynolds said. The aircraft has a lot of power for emissions, due to its four engines, he noted.
...
...
...
Service sources said the Air Force was willing to absorb some loss of EC-130s because its new F-35s have an inherent EW capability that will match or exceed what the EC-130s offer. Lockheed Martin, maker of the F-35, frequently points out that the Marine Corps plans to use a standard F-35, without any external jamming pods, as its EA-6B replacement.

https://www.f35.com/about/capabilities/ ... nicwarfare
ELECTRONIC WARFARE
Unprecedented Battlefield Access
The F-35’s advanced stealth and built-in electronic warfare capabilities enable unprecedented battlefield access without the need for dedicated electronic attack aircraft support.
Advanced electronic warfare capabilities enable the F-35 to locate and track enemy forces, jam radio frequencies and disrupt attacks with unparalleled precision. All three variants of the F-35 carry active, electronically scanned array (AESA) radars with sophisticated electronic attack capabilities, including false targets, network attack, advanced jamming and algorithm-packed data streams. This system allows the F-35 to reach well-defended targets and suppress enemy radars that threaten the F-35. In addition, the ASQ-239 system provides fully integrated radar warning, targeting support, and self-protection, to detect and defeat surface and airborne threats.
While F-35 is capable of stand-off jamming for other aircraft — providing 10 times the effective radiated power of any legacy fighter — F-35s can also operate in closer proximity to the threat (‘stand-in’) to provide jamming power many multiples that of any legacy fighter.
"What we've done with the 5th Generation [aircraft] is the computer takes all those sensory inputs, fuses it into information. The pilot sees a beautiful God's eye view of what's going on. [...] It's a stunning amount of information."
—Gen. Mike Hostage, Commander, Air Combat Command, U.S. Air Force
The F-35’s survivability, electronic attack, electronic protection, situational awareness, advanced targeting and unprecedented Combat ID will make the entire air wing better. Research indicates that adding more F-35s in a high threat environment is far more effective than adding more single-mission, electronic attack support aircraft. The electronic warfare suite on the F-35 gives improved emitter location capability over legacy aircraft.



A little Question about EW...
Q1) I have often seen the claim that "F-35's jamming is X-band only"
but...
What kind of band is Jamming with the Radar control vehicle(?) on the right of this BAE's video?
https://youtu.be/MFWoYKkKFyE?t=64
ASQ-239-1.gif
ASQ-239-2.gif


Q2) On the relationship EW and CNI(software-defined radio).
Is software-defined radio related to EW?
http://www.sldinfo.com/shaping-the-f-35 ... nterprise/
Take the AESA radar as an example. We commonly refer to it as an MFA, a multi-function array. It has, of course, many air-to-air modes, and many air-to-ground modes. But it also offers capabilities as a fully capable EW aperture. For EW, I mean electronic protection, electronic attack, and electronic support, the latter of which involves sensing or passive ops.
The bottom line is the AESA design incorporated as much connectivity, processing and as wide a bandwidth as technology allowed in order to maximize flexibility and spectrum coverage.
The radar interacts directly with the EW gear, which is imbedded on the F-35’s wing lines and other surfaces. The EW system gives you 360-degree coverage, and covers the radio frequency (RF) spectrum on the battlefield. The F-35 CNI system—communication, navigation and identification—is another flexible, reprogrammable system that further expands 360-degree RF spectrum coverage.
The radar and the EW system are symbiotic and are linked via a high-speed data bus built upon high-speed fiber optical systems. And the systems communicate virtually pulse-to-pulse to assist each other within the RF spectrum. So the radar can draw on advanced jamming resources, and the EW techniques can be channeled through the radar.
The AESA itself has its own attack modes as well and a very sensitive, precise geo-location capability, which can work in conjunction with EW gear. The CNI system is also linked via the high-speed data bus.

http://www.sldinfo.com/whitepapers/the- ... or-fusion/
The Electronic Warfare Suite
The plane has an electronic warfare suite. It has multiple functions and performs in an integrated manner with fusion.
Some of these functions include radar warning receiver (RWR), electronic support measures (ESM), and electronic countermeasure (ECM). These are functions that are federated on most 4th generation fighters.
In the F-35, the electronic warfare suite has all of these functions built into it, and it’s able to use the antennas all around the airplane, including the multi-function array, all under fusion control and with minimal pilot involvement.
As the airplane flies through battlespace, the EWS is tasked by fusion to build a picture of the electronic order of battle. It identifies emitters, locates them, classifies them and then reports to the pilot what it detects in battlespace.

CNI
The Communications, Navigation, and Identification (CNI) suite is a software-defined radio.
This means that there really aren’t radios in the traditional sense in an F-35. There is one real physical radio in the airplane hooked to the battery for emergencies, but other than that, everything else is a software radio.
Radios don’t exist until the pilot instantiates them with software.
The CNI system actually builds the radio in software once the computers initialize and run their programs.
Radio frequency (RF) waveforms such as Link 16, multi-function data link, instrument landing system, and voice get defined and built in software rather than being fixed in hardware. This scheme allows for tremendous growth and opportunity for change.
New data links and new waveforms are created in software, which, in many cases, means no new hardware to buy and install.

http://www.sldinfo.com/cni-and-madl-dat ... ith-f-35b/
The operational advantages of the new CNI system were highlighted by Major General Silveria of the Warfare Center at Nellis AFB.
The plane has NONE of the items that traditionally on airplanes to transmit and receive. It does not have any of those.
What it has is a rack two CNI (Combat, Navigation and Identification),com ad navigation racks.
It has two racks and you tell the airplane: I would like to transmit in the UHF wave form and it generates that wave form and transmits in the UHF wave form; which is a difficult concept to think about.
There is no UHF radio on the airplane.
There is no ILS on the airplane.
If I want an ILS I have to go in, tap on my glass, and say, hey, good morning jet, I’m going to need an ILS today so I need you to generate the ILS waveform when I need it.


http://www.airdominance.nl/index.php/aircraft-f35.html
Communications, Navigation and Identification (CNI) Avionics System
The CNI uses Software-defined radio (SDR) technology, SDR uses reconfigurable RF hardware and computer processors to run software that produces a desired waveform, the CNI can manage over 27 different wave-forms. One of the new wave-forms is the MultiFunction Advanced Data Link(MADL) developed for the F-35 which has a very high data transfer rate (for video streaming etc.) and is very hard to intercept or jam, giving the aircraft “stealth” communications.
It also acts in a Daisy Chain fashion to operate over wide areas with other F-35s and command and control operating centers. The F-35 will have LPI/LPD Link-16 capability as well. With its full suite of communications it can give information to another aircraft enhancing their situational awareness, this allows an F-35 that has expended its munitions to continue to act as an AWACS, furthering network centric warfare.
If an F-35 sees a ballistic missile it can give that information to a naval vessel who can send an SM-6 after it with the F-35’s targeting data, extending the range of AEGIS, or it can provide geo-coordinate data on a vehicle somewhere and guide in artillery GPS shells/rockets or missiles(tomahawks) etc. With the AESA radar the communications system can send or receive very large amounts of data very quickly.


Q3) Does this include jamming?
https://www.afcea.org/content/?q=progra ... ew-heights
Antennas also present an additional challenge. To maintain the F-35’s radar-evading silhouette, antennas must conform to the fighter’s shape. But building these systems into the skin of an aircraft can create issues such as co-site interference. Phan explains that one of the JSF program’s goals was to minimize the number of antennas on the aircraft. He adds that a ground vehicle can host a range of antennas for communications, jammers and other systems operating on the same band. The JSF does not have multiple antennas; its antennas operate on multiple frequencies and can perform different functions.


Q4) What is this "narrowband jammer"? Is it related to the VHF in the article?
https://www.f35.com/news/detail/the-f-3 ... vhf-threat
The F-35 vs. The VHF Threat
The Diplomat // August 21, 2014
The heated and ongoing international debate regarding the combat effectiveness of the F-35 Joint Strike Fighter (JSF) in a highly contested environment has led many observers to question the fighter’s survivability in the face of advanced Surface-to-Air Missile (SAM) systems and very high frequency (VHF) radars. Yet, few have examined the issue closely using lessons drawn from the only incident in which a stealth aircraft was lost in combat; when USAF Lt. Col. Dale Zelko’s F-117 – call sign “Vega 31” – was shot down by a Serbian S-125 (SA-3) SAM system over the then Federal Republic of Yugoslavia during Operation Allied Force on the night of March 27, 1999.
[...]
It is important to remember that the F-35 is no F-117. Designed with network-centric warfare and joint operations in mind, the JSF offers its pilot unprecedented situational awareness thanks to its ability to communicate and process data obtained from a multitude of both onboard sensors and those located on other platforms. Unlike the F-117, which had no radar, the F-35’s powerful AN/APG-81 AESA is also capable of acting as a narrowband jammer that can be employed if necessary against engagement radars once the jet is deep inside enemy territory. These features make the JSF a key “team player”; its capabilities and potential must therefore be viewed in the context of a CEC or collective system rather than as a single platform.

The F-35 and Advanced Sensor Fusion
NO DATE SLDinfo

"...Advanced fusion does three things for the pilot.
First, it assembles a single integrated picture from all of the sensors.
Second, it tasks the sensors to fill in missing data.
Third, it shares the information with everyone else on the network....

...The Distributed Aperture System
The Distributed Aperture System (DAS) is a new and unique sensor. The DAS is comprised of six staring focal point arrays. These are infrared cameras flush-mounted on the skin of the airplane, which detect the entire sphere around the airplane – that’s 4 pi steradians for the mathematically inclined. The entire sphere is about 41,000 square degrees whereas the radar sees about 10,000 square degrees. There is an intersection of the two sensors however. Where they’re both looking through the same angular volume of space, fusion will work them synergistically, and they can queue each other. Fusion really does the queuing. As soon as one sensor detects something, fusion then queues every other sensor to look along that line of sight and try to find information about the track. The impressive thing is that this occurs without pilot involvement.

When fusion recognizes a DAS track is in the same angular space as the radar it will indicate to the Radar: “Radar, go look along this line of sight and get range on this track that DAS found.” Or if the radar has a track and it gimbals, or in other words, the track goes beyond the radar’s field of regard, fusion will tell DAS, “You keep updating this and hold onto the track for the pilot until it comes back into the field of regard of the radar or comes back into the field of regard of some other sensor on the airplane,” according to Skaff...."

Why The F-35 Is The Iphone Of Fighter Aircraft
13 Mar 2017 Russ Read

"...Berke compared the introduction of the F-35 to the introduction of the first iPhone by Steve Jobs. The iPhone single-handedly redefined what we expect our cell phones to do. In turn, the F-35’s capabilities are redefining what a fighter aircraft is expected to do. Like the iPhone, the F-35’s introduction is disruptive, and Berke claims we are only on the cusp of discovering what it might be able to do in the future.

Berke outlined three major differences that put the F-35, and other fifth-generation aircraft (like the F-22), in a league of their own.... [BEST to READ at Source]

...F-35 manufacturer Lockheed-Martin offered the following example as to why to the sensor-fusion engine is a crucial addition in a white paper: http://www.sldinfo.com/whitepapers/the- ... or-fusion/

"An enemy pilot effectively neutralizes sensor A from one F-35 in a formation of several. The likelihood that enemy will be able to do the same to another F-35 in the same formation is slim to none. It is extremely difficult for the enemy to defeat multiple sensors on multiple F-35s simultaneously. Because the sensors between the F-35s are fused, the pilot in aircraft #1 can simply tap in to aircraft #2’s sensor suite."


...What makes the F-35 most like the iPhone is its user potential. Berke explained that the original iPhone was branded as an Mp3 player, cell phone and internet device, but developers have now made it so much more. Similarly, now that F-35 operators have their hands on the aircraft, they are likely to continue to develop its capabilities, according to Berke.

“The F-35, it’s light years beyond anything we already have,” said Berke. “The only way I know that is I flew F-18s, F-16s, F-22s and F-35s operationally for 23 years, that’s how I know that.”

Visiting the Pax River F-35 Integrated Task Force: Todd Miller Provides an Update
20 May 2016 Todd Miller

"...While the high level of “self-awareness” is a factor when launching and landing, it is also demonstrated an unprecedented capability to focus on mission. The very low observable (VLO) characteristics ensure the F-35 is shielded from easy discovery by hostile forces (shrinking hostile surface-to-air engagement zones), the sensors themselves are analyzing every emission — emitters, SAM sites, aircraft, missile launches, ground vehicles — and immediately locate and identify them equipping the pilot with a real-time picture of everything in the battlespace.

Watch your smartphone’s available Wi-Fi spots as you travel about? It’s a little like that, but much more serious business with the F-35 providing much more specific and critical information.

The F-35’s enhanced situational awareness provided by the sensor fusion ensures a superior OODA loop (Observe, Orient, Decide and Act) empowering First Look, First Shot, First Kill by the pilot. Designed to operate in the contested environment, making the right decision faster than the adversary delivers a decisive tactical advantage.

The same principles apply to air-to-air combat, with the simple objective to kill the hostile aircraft before it knows you are there — rather than in a “knife fight.” The superior sensors and sensor fusion enable an aircraft that is as much “multi-task” as “multi-role,” performing Intelligence, Surveillance & Reconnaissance (ISR), air-to-air (A2A) and air-to-ground (A2G) activities all on the same mission without need to reconfigure.

What the non-classified audience can’t know, but have some indication of, is the non-kinetic capabilities of the F-35.

To what extent can the F-35’s active electronically scanned array radar (AESA) beam jamming signals, high energy chip frying signals or even a virus to infiltrate the unprotected emitters of a hostile force?

Such a scenario makes Will Smith and Jeff Goldblum’s virus transferring effort in the Hollywood hit “Independence Day” obsolete. We can only speculate about the extent of those and other unknown capabilities.

However, it is clear that the F-35’s sensor suite delivers unprecedented capabilities for electronic and cyber warfare in a fighter aircraft.

http://www.sldinfo.com/shaping-a-21st-c ... warfare-2/

The exceptional capabilities of the F-35 are particularly relevant as the USAF, USN and USMC prepare for future warfare in a contested or non-permissive environment. Unlike environments such as Iraq and Afghanistan where the U.S. has enjoyed relatively unchallenged air superiority, the military must prepare for future environments that will involve operating against advanced air defense networks.

Beyond attacking and defeating hostile forces in such an environment, the USN sees the F-35C as an Intelligence, Surveillance, Target Acquisition and Reconnaissance (ISTAR) platform that will relay data back to the E-2D Hawkeye, F/A-18E/F and shipborne weapon systems for launch of stand-off strike weapons.

The testing required to ensure integration and validation of flight characteristics is primarily the task of the ITF team at NAS Pax River, while a similar team at Edwards AFB focuses on validation of the mission systems...."

Thanks, have seen them long ago when you or someone else shared them already. The fact remains however that the description of 4th gen sensor fusion capabilities is more generic and may apply to US teens, but it definitely doesn't match with that onboard a Rafale or Typhoon where the fusion is more complex and were fused tracks are updated with the best kinematic data available from all contributing sensors, where ID data are fused as well and where sensors are being tasked by the weapon system. While I have no doubt that the F-35 scores higher here as it's a newer platform, there are two points to consider 1. those older platforms including the F-22 have the advantage of being more mature, whereas the proposed sensor fusion capabilities of the F-35 have yet to be fully developed and 2. sensor and processor upgrades, incl. replacement of existing gear with entirely new gear as well as continued software development will help these platforms to stay competitive in that field. That doesn't mean that the F-35 won't have an edge over these older platforms, but the gap might not be as big as is being perceived, mostly due to the lack of awareness of the actual capabilities of these older platforms and due to the fact that a proposed future capability of a new platform is compared against what's available right now on existing platforms minus what people are apparently unaware off.

Don't expect me to know anything about the F-35. I have not seen it. I have not seen the 'travel simulator'. All I know is text/videos from the internet. Anyhoo... THERE will be links to same info below [SKAFF] somewhere which I'll find soon....
The Impact of Advanced Fusion in 5th Generation Fighters on Combat Capability
Michael Skaff, Lockheed Martin Aeronautics Company

"...The Tactical Situation Display
The Tactical Situation Display (TSD) is where the fusion engine’s picture is displayed.... Now, instead of the pilot monitoring a separate display per sensor, fusion presents a single integrated common operational picture (COP) on the TSD.

The picture is an easy to interpret graphical representation of what surrounds ownship. It is color coded such that red diamonds, green circles, and yellow squares correspond to foe, friend, and suspect.

The differing geometric shapes are Combat identification (CID) is performed automatically by using all of the information from each onboard sensor as well as offboard datalinks.

Another key aspect that enhances situation awareness is the use of common symbols across the services and international fleet of F-35s. In legacy fighter cockpits there are differing symbol sets.

There is a lot of learning and a high potential for misunderstanding as pilots communicate. Whether pilots are flying an F-35A, B, or C model, they use the exact same symbol set.

With the F-35, pilots are speaking the same language – no matter their service or nation – and using the exact same terms to describe what they’re seeing and how they’re interacting with the display.

It’s very graphical and very clear to the fleet. Its simplicity and standardization will one day enable ground commanders to easily use the pilot’s picture for an improved perspective on the battlefield...."

Shaping a New Approach to Combat Learning: The Role of the F-35
30 Nov 2012 Robbin Laird

"...Timperlake: Mike [Skaff], we came up through the generation of always trying to achieve SA, situational awareness. That was the nature of my fighter squadron and your your squadron, too.

I think now with the F-35 cockpit, you’ve moved to a different level, a paradigm shift of situational decision making with information available across the fleet even to the youngest aviator.

They have situational awareness, but it takes it to a different dimension, it takes it to situational decision making in the context of the particular environment they’re in.

And that, I think, is a revolution, which makes it an action item as just opposed to an awareness item. You can use information as a weapon. You can use kinetics, and the machine/man interface will allow an evolving battle management fleet to address current and near-term threats.

Are we entering a new era of deterrents and airborne situational decision making?

Skaff: Yes, and I think we can relate it to our experiences.

As a young blue 4 wingman, I had no clue what was going on. For 300 hours, they drug me up and down the East Coast. I could fly formation, but I couldn’t do much else. In fact, I wasn’t sure I’d ever figure this out; it was so complicated in an F-16. And now, because what you’ve been talking about, blue 4 has the same knowledge as 1 does.

If one gets shot down or has to return to base for some reason, two has the knowledge one has and can just take over.

This is the value of distributed information.

Timperlake: So, we have a constant sorting of consistent information...."

The Impact of Advanced Fusion in 5th Generation Fighters on Combat Capability
Michael Skaff, Lockheed Martin Aeronautics Company

"...Mitigating Information Overload
...Information overload leads to pilot task saturation and channelized attention which is deleterious to survival. Pilots may become preoccupied trying to interpret information when they need to be focused elsewhere....

...This [F-35 Sensor Fusion] design is fully integrated with the sensor control and display suite in order to provide the
picture, perform automatic sensor tasking, and connectivity with the other fusion engines on the datalink.

In the 5th generation the advanced sensor suite is planned and built in from the inception of the weapon system.

Advanced sensor fusion is one of the hallmarks of the 5th generation.

Its contribution is far more than situation awareness and manageable workload. It provides information dominance.

Information dominance determines winners and losers in tactical aviation.

‘A God’s Eye View Of The Battlefield:’ Gen. Hostage On The F-35
06 Jun 2014 Colin Clark

"...In our interview, Gen. Hostage points to the plane’s ability to gather enormous amounts of data, comb through it and very rapidly and simply present the pilot with clear choices as a key to its success.

“People think stealth is what defines fifth gen[eration aircraft]. It’s not the only thing. It’s stealth and then the avionics and the fusion of avionics. In my fourth gen airplane, I was the fusion engine, the pilot was the fusion engine. I took the inputs from the RHWG, from the Radar Homing Warning Gear, from the radar, from the com, multiple radios, from my instruments. I fused that into what was happening in the battlespace, all the while I’m trying to do the mechanical things of flying my airplane and dodging missiles and all these sorts of things,” he says.

Combine the fusion engine, the ISR sensors, the designed-in stealth, the advanced helmet, and the eight million lines of software driving what it can do, add weapons to the stealthy weapon bays, add a pilot and that is what allows you to “break the enemy’s kill chain,” as Hostage likes to put it.

“What we’ve done with the fifth generation is the computer takes all those sensory inputs, fuses it into information. The pilot sees a beautiful God’s eye view of what’s going on. And instead of having to fuse three pieces of information and decide if that’s an adversary or not, the airplane is telling him with an extremely high degree of confidence what that adversary is and what they’re doing and what all your wingmen are doing. It’s a stunning amount of information,” Hostage says...."

[RAAF] Air Combat Operations 2025 and Beyond
SEMINAR EXECUTIVE SUMMARY Andrew McLaughlin April 2014

"...SQNLDR Harper [RAAF F-22 exchange pilot] said the fusion is the “key enabler” for 5th gen. He said because the sensors require little or no manipulation means it “frees up huge amount of brain space for the pilot.” [NOT a brain Freeze] He said all the relevant information is presented in sync “not just your own aircraft, but with the entire formation.”

LtCol Berke [USMC F-22/F-35 pilot] described the fusion offered by 5th gen platforms as “an overwhelming advancement in breadth and depth in terms of the spectrum in which it operates.” He said it’s unlikely we fully understand what that breadth and depth will allow pilots to do yet due to the vast differences to the capabilities offered by legacy platforms. “It’s not just a matter of being able to function in a wide array of information – if we can’t fight in a particular spectrum, whether it’s RF, IR, laser, EO, the F-35 has the ability with the agility on the platform to live in whatever spectrum it thinks it needs to be in.”...”
