Participants of the F-22 SRP project and the last refurbished aircraft


The United States Air Force has completed the F-22 Structural Repair Program. Its goal was to overhaul and restore the technical condition of the existing 5th generation Lockheed Martin F-22A Raptor fighters. As a result of the program, the entire fleet of these aircraft meets the requirements, and the service life of the equipment has grown to the planned 8 thousand hours.

Aging problem


Serial production of F-22A fighters was launched in 2001 and continued until 2011. The first plans called for the purchase of hundreds of aircraft, but due to the high cost and constant disputes at different levels, only 187 production fighters were built. With the exception of a few lost vehicles, they remain in the ranks and solve the assigned tasks.

The first production F-22A reached operational readiness and became full-fledged combat units in 2004-2005. It is easy to calculate that these aircraft remain in service for more than 15 years and have managed to develop a significant part of their service life. The last fighters this year will celebrate their tenth anniversary - which also affects their condition and prospects.


The design resource of the F-22A fighter is 8 thousand flight hours, but this requires repairs after several years of operation. A related maintenance program called the Structural Repair Program was launched in 2006-2007. Over the next years, it was planned to monitor the service of aircraft and monitor the development of the resource, and after reaching certain indicators, send equipment for restoration.

On January 26, the Air Force announced the completion of work on the SRP. Over the years, all combatant F-22As have undergone repairs and refurbishment - some of them more than once. The last of the machines was tested at the end of last year. Based on the results of the repair, the flight life of each aircraft was brought to the design 8 thousand hours. This allows him to remain in service for 40 years.

Works and their performers


The F-22 SRP program was carried out by several organizations. The main work was entrusted to the 574th Maintenance Squadron from the Ogden Air Logistics Complex. The squadron received a full set of equipment and equipment for the inspection and repair of equipment. In addition, Lockheed Martin and Boeing, which previously participated in serial production, played a large role in the program.


Last refurbished F-22A on trial

Over the past years, the 574th squadron has carried out repair work on 247 aircraft. This means that about a quarter of the cars were restored in several stages, as the service continued. 8645 applications were completed, which required more than 3,88 million man-hours.

Some details of the work carried out are reported. So, 1,55 million man-hours were spent on the restoration of the unique coating of the aircraft skin. For all its advantages, it is regularly criticized. New data from 574 Squadron reveals the scale of the problem in terms of maintenance. Another 2,328 million hours were spent on anti-corrosion, redesign, modernization and general repairs.

It is noted that the companies made a significant contribution to the repair work aviation industry. They provided the necessary tools and devices, technologies, etc. In addition, company representatives constantly monitored the progress of the work.

In parallel with the modernization work in the framework of the F-22 SRP, planned and unscheduled repairs of damaged equipment were carried out. Thus, the forces of the 574th squadron restored five seriously damaged aircraft over several years, which took 50,9 thousand man-hours.


New program


After completing the F-22 SRP program, 574th Squadron and its allies will continue to service and upgrade fighters. Plans for the near future have already been announced. Specialists will have to continue to inspect and restore equipment, focusing on several main areas.

Immediate plans include inspection and overhaul of aircraft control systems and controls. In addition, the air intakes and their coating need restoration. In parallel, the modernization of on-board radio-electronic equipment will continue in order to improve the current characteristics and obtain new opportunities.

A new stage of updating and maintaining the state of technology has already started. It is reported that the necessary procedures have already passed nine aircraft. It took approx. 200 thousand hours. Work will continue until the entire park is updated.

Plans for the future


The current electronics upgrade is part of the Raptor Agile Capability Release 1 (RACR 1) project, which runs until 2024. This project is reported to affect communications systems, electronic warfare and cockpit equipment. All these measures will expand the capabilities of aircraft, as well as relieve them of inherent problems.


Engine nacelle repair

In its current form, the F-22A communicate using its own IDL (Intraflight Data Link) protocol, and additional hardware is required for integration into the Link 16 circuits. As part of RACR 1, aircraft will receive communication equipment compatible with the Link 16 bus. In addition, they will introduce the Multifunction Information Distribution System-Joint (MIDS-J) system, with the help of which the fighter will be able to effectively operate in the same network with other aircraft, ships and ground forces. ...

In 2024, a new modernization program starts - Mid-Life Upgrade. The development of such an upgrade has not yet been completed. It is assumed that the updated F-22A will receive new radar and other means, a modern computer, new weapons, etc.

Realizing the potential


The F-22A Raptor fighter was completed 10 years ago, but it still retains the title of the most complex and expensive tactical aircraft in the world. This status is reflected in a known way in the specifics of operation, maintenance and modernization. In particular, there is a need for a long and continuous process of repair and gradual renovation.


Radar absorbing coating recovery process

To date, F-22A aircraft have undergone several refurbishment and restoration programs. The recently completed SRP has become one of the largest and most important, as it will fully realize the full potential of an expensive and complex aircraft. In addition, it creates the foundation for future upgrades to RACR 1 and MLU.

The US Air Force plans to keep the F-22A fighters in service until at least the middle of the XNUMXst century. Moreover, assessments are expressed about the fundamental possibility of their operation until the sixties. It appears that the SRP and the expected MLU will not be the last update programs, and similar projects will be carried out regularly in the future.

All this will make it possible to continue operating the uniquely expensive aircraft for as long as possible and to maximize their potential - which is especially important in view of the high cost of the project at all stages. The task of extending the service life of the F-22A to design values ​​has been successfully solved, and now aircraft manufacturers and the Air Force will have to develop and carry out new upgrades. The results of these projects will become known only in the distant future.

                        Ferite paints and radio-absorbing materials were known and used at the end of WWII. Including by the Germans for covering / covering (casing made of radio-absorbing fabric) periscopes and snorkels of their submarines, thus protecting themselves from detection by British anti-submarine aircraft, using on-board centimeter range radars.
                        Are you looking for a radar specialist?
                        It is in front of you, and I confirm that radio-absorbing paints are known in our country (in the USSR) and have been used at least since the 60s. This paint was used to cover reconnaissance drones (the USSR was the leader in their use) and aircraft, incl. bomber aviation. But the disadvantage of these paints is that they are very unstable.
                        And yet, much more important for stealth is the shape of the fuselage, because the articulations of the wing, elevators, tail, at right angles, works as a corner reflector. That is why in the aircraft of the latest generation they make the collapse of the keels, they abandoned the ventral keels (by the way, the Chinese have these keels on the J-20, and therefore it will be clearly visible on the radars), they began to make transitional elements at the junction of the fuselage and the wing, elevators , as well as on the 4th generation aircraft, they switched to an integrated circuit (the aircraft does not have a fuselage - it has a center section that smoothly flows into the wing). It is these measures - the integrated circuit, the rejection of rectangular joints, the camber of the keels and of course it - the radio-absorbing paint / coating, very seriously reduced the RCS of the 4th generation fighters ... By about an order of magnitude.
                        On aircraft of the 5th generation, this trend was continued and deepened - the configuration of the airframe was calculated on a computer, and instead of radio-absorbing paint, they switched to a radio-absorbing coating (it is thicker, approximately like a car putty. For the absorbing properties depend to a large extent on the thickness of the coating.
                        But the durability of this coating is still low. Under the influence of water formation (flights in the rain and through clouds) and thermal heating at high supersonic speeds, they begin to swell and flake off.
                        And they couldn't do anything about it at the moment.
                        It's just that for the F-22 and F-35, they introduced speed limits and flights in rainy weather.
                        And they are forced to keep them in hangars with a microclimate, because the coating absorbs moisture well ... while losing strength.

                    I'll add a little bit - the thickness of the FM coating has a thickness equal to a quarter of a wavelength or a multiple of an odd number of quarters of a wave, as a result of which the reflected vibrations from neighboring layers are in antiphase

                    That is why it will always be visible in meters and decimeters. But for the radar of fighters and seeker missiles, this is a serious problem. A multi-frequency signal (pulse) can make the task easier ... I think it does.

                    this is a common misconception. In fact, the coating can be created from any wavelength. It is impossible to create multi-coatings that absorb waves of all lengths - from 2-5cm to 100m. Therefore, the created coatings absorb waves of the main sector - 3-5 cm, i.e. sector of wavelengths of the main combat radars. It is clear that the coverage will not work for over-the-horizon radars with their wavelengths ranging from a meter and above. And all hope is only for the geometry of the glider.

        Understood, do not leave me, I am improving, I want to communicate !!!
        From an NI article (2009)
        "The real secret to keeping the F-22 and F-35 invisible is their super special" skin "
        And ground crews that keep the coverage intact.
        Without proper skin care, these advanced stealth aircraft degrade over time, leaving them vulnerable to enemy radar.
        Radar Absorbing Material (RAM) is a special class of polymer-based materials applied to the surface of military stealth aircraft such as the F-22 Raptor and F-35 Lightning II to reduce the cross-section for radar and thus be more difficult to detect by radar ...
        The absorption capacity of a material at a given radar wave frequency depends on its composition. RAM cannot completely absorb radar at any frequency, but any compound does have a greater absorbency at some frequencies than others; no RAM is suitable for absorbing all radar frequencies. A common misconception is that RAM makes an object invisible to radars. Radar absorbing material can significantly reduce the radar cross section of an object at certain radar frequencies, but this does not lead to "invisibility" at any frequency. Bad weather can help reduce stealth.
        https://nationalinterest.org/blog/the-buzz/the-real-secret-keeping-f-22-f-35-stealth-their-super-19559
        It is with this material, RAM, that the surface of the aircraft is covered, i.e. make the rivets invisible. When Russia creates such a coating (and it must withstand supersonic, sun, rain, lightning strike), only then it will be possible to remove all the Pros after 4 (4 ++) and proudly say “fifth generation”.

          Why do I need these extracts from NI? about ferro-magnets I know much more scribblers from there.
          The absorption capacity of a material at a given radar wave frequency depends on its composition. RAM cannot completely absorb radar at any frequency, but any compound does have greater absorption capacity at some frequencies than others.

          because in order to absorb or attenuate the energy of the incident wave, it is necessary to make the thickness of the FM coating equal to a quarter of the wavelength or a multiple of an odd number of quarters of the wave. Moreover, the angle of incidence of the wave is also important for the dielectric and magnetic permeability.
          When Russia creates such a coating (and it must withstand supersonic, sun, rain, lightning strike), only then it will be possible to remove all the Pros after 4 (4 ++) and proudly say “fifth generation”.

          And from what naive fright did you get the idea that the physics of RPM coatings is known only to the USA? This is a famous sofa hamster pattern. Actually, the Germans began to indulge in this at the end of WW2. And now RPM can be made even in the form of paint, sealants, polymers, even in the form of tiles and foam. Anechoic chambers with RPM coating appeared in the late 50s.

    The appearance of the super concern for the production of the F-22 made a real revolution in the American aviation industry. The main contractor was Lockheed Martin. At the Fort Worth plant purchased from GD, the aggregate assembly of the middle part of the fuselage, as well as the main systems - control, hydraulics, etc., was deployed. General Daynemics itself also has a share, supplying individual components of weapons, for example, the M61A-2 cannon. The wing consoles and the tail section of the fuselage are made by Boeing, followed by joint development of combat systems and a training complex.


    The F119 engines are manufactured by Pratt-Whitney. The APG-77 radar assembles Northrop-Grumman from Retheion components at production facilities purchased from the specialized firms Westinghouse and Texas Instruments. Reteyon, on the other hand, produces Intel processors for onboard computers, for which he bought the plant from Hughes, which was not involved in this part of the program.

    The sighting indicator naone of the windshield is a Collins-Kaiser product, and it will also make all the optics that the F-22 will receive during the upgrade. The ASQ-220 integrated radio system for communication, navigation and identification "friend or foe" was commissioned by TRW.

    For the first time in many years, a foreign enterprise was admitted to a program of this magnitude. The avionics department of British Aerospace (BAE) has received orders for the ALR-94 electronic warfare system, the AAR-56 missile launch warning station, the ALE-52 thermal and radar trap ejection system,
    -and also the holy of holies - fly-by-wire system of the main control of the aircraft and equipment for monitoring the state of the airframe and on-board systems. But all this must be done in the USA under the contract ..

    Reducing the RCS made it possible to no longer hide from enemy radars at low altitudes and to go to the target at an altitude of 12000 m, which is optimal in terms of fuel consumption at M> 1. With high-altitude interception, when time is limited, the F-11 aircraft climbs to 15 km according to a complex program, changing the M number from 0,6 to 0,98, and only above 11 km gaining altitude with M> 1,0. The F-22 gains altitude best of all with a constant M = 1,5 and, due to this, has a greater interception line.



    The F-22 camouflage was developed using the latest technology, making the aircraft minimally visible to missiles with an optical guidance system




    Its acceleration data at "maximum" is the same as that of the F-15C at full afterburner, and the inclusion of the afterburner gives the new fighter an advantage in acceleration over the F-15 by 1,25 ... 1,5 times. But even without this, entering into an air battle at a higher speed compared to a conventional aircraft expands the zones of possible maneuvers and makes it possible for the first to take a position for shooting. If the F-15 maintains stability at angles of attack from +30 to -10 degrees, then the Raptor feels confident in the range of + 60o ... -40o.



    Test flight of the F-22A. The opening of hatches of internal weapon bays during flight at high speeds is practiced



    air battles were simulated with all American combat aircraft, and everywhere the F-22 showed convincing superiority. But what is interesting is that there is no mention of "air battles" with the MiG-29, and in the United States there are several aircraft of this type sold by Moldova. It is hard to believe that such tests were not carried out at all, probably the reason for the silence is the not entirely convincing results.

        The ability to identify any signal depends not only on the power of the station and not only on the ability to send and receive a signal, if possible, differing in the spectral packet from noise, but also on the ability of the processor part to simulate a noise picture and "subtract" it from the analyzed signal at the input , knowing the picture of the signal at the output.

    But the durability of this coating is still low. Under the influence of water formation (flights in rain and through clouds) and heat warming at high supersonic speeds, they begin to swell and flake off.
    And they couldn't do anything about it at the moment.
    It's just that for the F-22 and F-35, they introduced speed limits and flights in rainy weather.
    And they are forced to keep them in hangars with a microclimate, because the coating absorbs moisture well ... while losing strength.

    - You are "somewhat" exaggerating ... laughing lol (F-22 in Alaska)

    Compare the radar signature of the Su-35 and the Su-27. The fuselages are identical, but the EPR ... are very different.
    yes This is just it - PAINT.

    - Are you absolutely sure of that ?! Share a link? wink

    The avionics department of British Aerospace (BAE) has received orders for the ALR-94 electronic warfare system ...

    - Only ALR-94 is not an electronic warfare system, but an RTR system - electronic intelligence. There are no electronic warfare stations on the F-22. ALL ... lol

    That is why it will always be visible in meters and decimeters.

    - Stele-planes (F-22 and F-35) and in the decimeter range are visible almost as faintly as in the centimeter range, and in the meter range their RCS is greater than in the centimeter range by about an order of magnitude, not more.

    Alas, the assembly technology remained at the level of the 70s. A lot of small parts, cannot make complex, one-piece airframe construction elements.
    On the geometry of the airframe alone, you will not get into the 5th generation. Of course, our Su-57 is not much different from the Su-35 now, but let's hope in 10 years it will be brought to a full-fledged machine.

    That is, 15 years for the repair of about 150 aircraft, after which "Immediate plans provide for inspection and overhaul of aircraft control systems and controls. In addition, the air intakes and their coating need to be restored." ? Delightful in my opinion laughing
