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

11 Sep 2017, 16:27

Description about F-35 EW.
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.

2 ... ghter.aspx
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.

3 ... 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.

4 ... 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.

5 ... nicwarfare
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"
What kind of band is Jamming with the Radar control vehicle(?) on the right of this BAE's video?

Q2) On the relationship EW and CNI(software-defined radio).
Is software-defined radio related to EW? ... 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. ... 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.

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. ... 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.
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? ... 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? ... 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.

Sorry many Questions...I do not know EW well...@@@@ :oops:(F-35 is particularly complicated!)

The F-35 and Advanced Sensor Fusion

"...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: ... 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. ... 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.

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...."

Here is an excellent overview of the fusion engine ('AI'?) in the F-35 and there are plenty more on this forum & out there:
[search F-35 forum for 'SKAFF' will find a bunch of good stuff with the graphics (many in the PDF below not replicated here]. These cited articles are not only sometimes difficult to read (requiring graphics for explanation for example) but difficult to excerpt so these only POINT to the overall effect of the article.
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.”...”

RAAF: Air Combat Operations 2025 and Beyond PDF

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

The step change in capability the F-35 will bring was a recurring theme throughout the seminar presentations. Speakers consistently pointed to the aircraft’s advanced sensors, LPI communications, low observability, improved situational awareness, and other advanced systems as the key attributes that differentiate the F-35 from its predecessors.

To emphasise the advances in sensors and other systems, AIRMSHL Brown explained how the classic Hornet which was developed in the 1970s is a very different aircraft today to the one the RAAF initially acquired. In the last decade the Hornet has undergone a massive mid-life upgrade program which has seen it equipped with a more capable APG-73 radar, Link 16 and ARC-210 comms suite, enhanced cockpit displays, an advanced electronic warfare suite, a helmet mounted cueing system with new high PK active and high off-bore sight air-to-air missiles, and precision-guided and stand-off air-to-surface weapons.

He related a recent experience he had when flying an upgraded Hornet in a training mission. Despite being in a dominant position against a relatively new Hornet pilot, he was ‘killed’ by an over the shoulder ASRAAM missile shot which had been ‘spiked’ and uncaged by the pilot’s helmet mounted cueing system. He remembers that event as a “technological development that had fundamentally changed my mind as to what was offensive and what was defensive.”

SQNLDR Matthew Harper offered a clear insight by comparing his experiences in flying the 4th generation classic Hornet and the 4.5 generation Super Hornet in the RAAF, and the 5th generation F-22 Raptor while on exchange with the USAF.

He told the audience that, despite the advances which have made the classic Hornet “one of the best 4th generation aircraft out there”, the aircraft is still very limited. He spoke of the mechanically scanned radar which needs to be “driven by the pilot” and which is restricted in the number of targets it can see and track, and of the limitations of the Link 16 network and the compromises that need to be made when “everyone wants to use it”.

He also explained that the Hornet is “not low-observable in any way”, that its mission computers are at 100 per cent capacity, and that sensor performance is very sensitive to the operator’s skill levels. Sensor fusion for a Hornet pilot essentially means looking at multiple displays, each one displaying a different sensor picture which may not be up-to-date due to Link 16 limitations, and often means having to make a best-guess decision based on poor situational awareness. He said with the Hornet, in the decade ahead “it’s increasingly obvious we don’t have the systems capability to offer a meaningful contribution to the fight.”

With the Super Hornet, SQNLDR Harper said the improvements brought by the AESA radar, integrated electronic warfare features, some low observable enhancements, the advanced mission computer, and better sensor fusion which provides greater ability to manage complex EW & targeting, have made a “fantastic jet” even better. He said the improvements were “designed to a sensible point which made financial sense”, and would mean the Super Hornet is survivable and upgradeable into the 2020s.

But he said the Super Hornet was still limited by being confined to a Link 16 network which isn’t LPI, and despite the better sensors the lack of real sensor fusion “adds a layer of complexity” which can result in task saturation. “It’s still very challenging to determine what the best way is to track an adversary and maintain SA against advanced threats,” he said.

By comparison, SQNLDR Harper said the 5th generation F-22 was built from the ground up to optimise its capabilities, and that there is a real impression that the platform was “built in collaboration with engineers, scientists, fighter pilots, and warriors.”

He said the most important feature of 5th generation is its integrated avionics, and that “all the sensors are built into the jet” and are all controlled by a central core processor, which means the pilot doesn’t need to manipulate them. He explained that the cockpit displays promote an “evolved level of pilot interaction with the platform,” and that the HMI is “incredibly intuitive – It wasn’t long at all to go from the previous mindset, to looking at the displays and working with the picture to set up a work flow.”

SQNLDR Harper 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.” He said all the relevant information is presented in sync “not just your own aircraft, but with the entire formation.”

LtCol Berke 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.”..."
