So after reading several articles it appears the F-22 is not going to be restarted since the cost for about 200 more would be 50 billion. Was a stupid decision in 2009 to cancel the F-22, but I guess we are where we are.

One of the things that comes up over and over is that the Raptors avionics are dated...I'm a little confused on that since the F-15 and F-16 were built decades before and nobody ever talks about their systems being dated and the difficulties of upgrading them. Any clarification?

Thanks

The first serial F-15 and F-16 aircraft may have been produced decades ago, but I assure you the ones rolling off the assembly line now for international buyers share only the designation and general outline with their initial predecessors. They are essentially brand new aircraft with the latest systems and engineering available incorporated into the airframe known as F-15 or F-16.

Every tactical or strategic aircraft undergoes scheduled upgrades and modifications by adding and expanding capability keep them current and ahead of the threat curve, whether that threat is structural maintenance or new enemy IADS systems.

The article below does a pretty good job of breaking down the F-22 modernization road map. It seems the F-22 is going to become more stealthy (via new RAM coating), more aware and connected (via new and more sensitive antenna), more lethal (via AIM-120D, AIM-9X II and full ground strike capability) and better able to share targeting and information with legacy aircraft (via new data links).

Interestingly no mention of any electronic attack enhancement, but there is reference to a 'next generation sensor'. Anyone have more information on this? Do they mean radar replacement or possibly IRST or maybe ALR-94 switch? I know originally the ATF F-22 was designed to have cheek radar arrays and two wing root housed IRST pods. Of note is no mention of any engine upgrade, probably because the F119 is a marvelous efficient beast and the Raptor has excess thrust as it is, but also no mention of a helmet combat system.

I see mention of a two way Link 16 capability to share sensor information/targeting data with legacy aircraft. However I thought they were designing and were going to integrate a new and more capable system called the TTNT? In my opinion this is one of the crucial areas of need. Giving the F-22 a stealthy and sure way to link/network in with legacy aircraft in order to increase their effectiveness and possibly even take over and guide their weapons to target would be very significant.

The Air Force is in the early phases of creating new sensors and performing substantial software upgrades to its F-22 Raptor to enable the stealth platform to fire new advanced weaponry, better identify targets and perform a wider scope of attack missions.

The software improvement will permit the Raptor to improve its air-to-air and air-to-surface strike technology, service officials said.

The weapons modernization effort includes both software and hardware improvements to the aircraft, service and industry developers said.

"In the Summer of 2019, the F-22 fleet will begin to receive upgrades to its available weapons with the Increment 3.2B upgrade. This upgrade allows full functionality for the AIM-120D and AIM-9X Air-to-Air missiles as well as enhanced Air-to-Surface target location capabilities," said 1st Lt. Carrie J. Volpe, Action Officer, Air Combat Command Public Affair, Joint Base Langley-Eustis, Va.

An essential software adjustment, called “Update 6,” is now being worked on by Lockheed Martin engineers on contract with the Air Force. Work on the software is slated to be finished by 2020, said John Cottam, F-22 Program Deputy, Lockheed Martin Aeronautics.

A hardware portion of the upgrades, called a “tactical mandate,” involves engineering new antennas specifically designed to preserve the stealth configuration of the F-22.

Lockheed plans to have the “tactical mandate” portion of the work finished by 2021, he added.

Also, the Air Force is beginning the process of identifying requirements for a next-generation sensor for the F-22.

“Enhancing sensor capabilities is needed to keep the F-22 as an air-dominance platform into the future. Threats are always evolving so we need to evolve this plane as well,” Cottam said.

Additional future enhancements to the F-22 include the addition of a LINK-16 datalink designed to enable digital communications between 4th and 5th generation airplanes.

Lockheed Martin Selects Harris Corporation to Upgrade F-35 Lightning

June 20, 2017

Lockheed Martin has selected Harris Corporation to upgrade mission system avionics for the F-35 Lightning II as part of the Technology Refresh #3 (TR3) program, significantly boosting the aircraft’s data storage, display processing and throughput capabilities. The announcement was made during the International Paris Air Show being held June 19-25 in Le Bourget.
Harris will provide the Aircraft Memory System (AMS) and Panoramic Cockpit Display Electronic Unit (PCD EU), which are based on open architecture and commercial-off-the-shelf (COTS) technology. The AMS provides solid-state mass storage capability for the F-35 aircraft avionics subsystems. It is the repository for avionics operational flight programs, mission and theater data, prognostics and health data, audio, display video, and aircraft parametric data. The PCD EU provides processing for the panoramic head-down display in the cockpit.

“The new TR3 electronics pave the way for system upgrades well into the future,” said Ed Zoiss, president, Harris Electronic Systems. “Open systems are the future of avionics and Harris is investing substantial R&D to develop these solutions. These awards affirm the military’s approach to open systems architecture and Harris’ commitment to delivering more affordable, higher performance solutions than would have been possible using proprietary technology.” The technology development phase will begin in June 2017, followed by a system qualification phase in early 2019, and a subsequent 5-year production contract phase. Harris avionics and ruggedized open systems mission processing technology already support the F-35, F-22, and F/A-18.

Air Force Plans to Engineer New F-22 Sensor Targeting Technology

Scout Warrior
05/31/2017

The Air Force is in the early phases of designing new sensors for its stealthy 5th-generation F-22 Raptor as it proceeds with software upgrades, hardware adjustments, new antennas and data link improvements designed to better enable to connect the F-22 and F-35 sensor packages to one another, industry officials explained. Sensor interoperability, two-way data links and other kinds of technical integration between the two 5th-Gen stealth aircraft are considered key to an Air Force combat strategy which intends for the F-22 speed and air-to-air combat supremacy to complement and work in tandem with the F-35's next-gen sensors, precision-attack technology, computers and multi-role fighting mission ability.
"The F-22 is designed to fly in concert with F-35. Software Update 6 for the F-22 will give the Air Force a chance to link their sensor packages together. Sensors are a key component to its capability. As the F-22 gets its new weapons on board – you are going to need to upgrade the sensors to use the new weapons capability," John Cottam, F-22 Program Deputy, Lockheed Martin Aeronautics, told Scout Warrior in an interview. ....

Like the F-35, the latest F-22s have radar (Synthetic Aperture Radar) and data-links (F-22 has LINK 16), radar warning receivers and targeting technologies. Being that the F-22 is regarded as the world's best air-to-air platform, an ability for an F-35 and F-22 to more quickly exchange sensor information such as targeting data would produce a potentially unprecedented battlefield advantage, industry developers and Air Force senior leaders have explained. The combined impact of each of the airplanes respective technological advantages makes for an unrivaled air-combat supremacy, observers have argued. ....

Along these lines, both the F-22 and F-35 are engineered to draw from "mission data files," described as on-board libraries storing information on known threats in particular geographical locations. This database is integrated into a radar warning receiver so that aircraft have the earliest possible indication of the threats they are seeing. Air Force officials have told Scout Warrior that, by 2019, the service will begin upgrading F-22 functionality for the AIM-120D and AIM-9X Air-to-Air missiles as well as enhanced Air-to-Surface target location capabilities. 

The F-22 currently carries the AIM-9X Block 1 and the current upgrade will enable carriage of AIM-9X Block 2. ....
Another part of the weapons upgrade includes engineering the F-22 to fire the AIM-120D....

As the Air Force and Lockheed Martin move forward with weapons envelope expansions and enhancements for the F-22, there is of course a commensurate need to upgrade software and its on-board sensors to adjust to emerging future threats, industry developers explained. Ultimately, this effort will lead the Air Force to draft up requirements for new F-22 sensors. 

Cottam also explained that the House and Senate have directed the Air Force to look at two different potential sensor upgrades for the F-22, an effort the service is now in the conceptual phase of exploring. ....

An essential software adjustment, called “Update 6,” is now being worked on by Lockheed Martin engineers on contract with the Air Force. Work on the software is slated to be finished by 2020, Cottam added. 

 A hardware portion of the upgrades, called a “tactical mandate,” involves engineering new antennas specifically designed to preserve the stealth configuration of the F-22. ....

Meanwhile, the Air Force is performing key maintenance on the F-22 Raptor's stealth materials while upgrading the stealth fighter with new attack weapons to include improved air-to-air and air-to-surface strike technology, service officials said. ....

Additional upgrades to the stealth fighter, slated for 2021, are designed to better enable digital communications via data links with 4th and 5th generation airplanes. "The backbone of this upgrade also includes the installation of an open systems architecture that will allow for future upgrades to be done faster and at less expense than could be previously accomplished," 1st Lt. Carrie J. Volpe, Action Officer, Air Combat Command Public Affair, Joint Base Langley-Eustis, Va., told Scout Warrior. ....

At the moment, targeting information from drones is relayed from the ground station back up to an F-22.  However, computer algorithms and technology is fast evolving such that aircraft like an F-22s will soon be able to quickly view drone video feeds in the cockpit without needing a ground station -- and eventually be able to control nearby drones from the air. These developments were highlighted in a special Scout Warrior interview with Air Force Chief Scientist Greg Zacharias. Zacharias explained that fifth generation fighters such as the F-35 and F-22 are quickly approaching an ability to command-and-control nearby drones from the air. This would allow unmanned systems to deliver payload, test enemy air defenses and potentially extend the reach of ISR missions.

Newer F-22s have a technology called Synthetic Aperture Radar, or SAR, which uses electromagnetic signals or “pings” to deliver a picture or rendering of the terrain below, allow for better target identification. The SAR technology sends a ping to the ground and then analyzes the return signal to calculate the contours, distance and characteristics of the ground below. ....

“The F-22 possesses a sophisticated sensor suite allowing the pilot to track, identify, shoot and kill air-to-air threats before being detected. Significant advances in cockpit design and sensor fusion improve the pilot's situational awareness,” he said.
It also uses what’s called a radar-warning receiver, a technology which uses an updateable data base called “mission data files” to recognize a wide-range of enemy fighters, Broadwell said. ....
