Question for the Subject Matter Experts in the thread: how is restarting the F22 production line different from Reagan restarting the B1 line in the 80s? View Quote Apples to hand grenade comparison. Reagan resurrected the B-1 program, not the assembly line. There were never production B-1As, and the B-1B was a significantly redesigned airplane. The F-22 program was funded to produce 750 aircraft, to replace all of our F-15s, the R&D was all spent, and then we let the penny pinching morons in congress cut the buy to fewer than 200, squandering the investment in R&D. |

Where is the tooling for the future 6th generation fighter? What about the supply chain for it?
Seems to me like an F-22B model would still be less expensive than designing a completely new airframe from the ground up. Do it sort of like the hornet/super horner deal. |

My dad was on the B-1B CTF at Edwards when we returned from West Germany, and I remember many things about the program, to include Doug Benefield's death in the crash they had in one of the prototypes that still had the capsule.

I worked on the F22 program for many years (I started in the mid eighties). A lot of us have retired and we took our knowledge with us. Management wasn't interested in maintaining the old design tools we used to create the F22. Most of the work I did would have to be completely redone from scratch. I retired about 8 years ago and even back then our knowledge base had moved on to other jobs. So there is no such thing as a re-start, there is nothing left to restart. Any such thought would be the near equivalent of starting from zero with a few minor exceptions.

Why try to bother? Half the stuff you would need may have gotten stored somewhere, so it may be found once again in a few decades by accident.
But most of the stuff you need to build F-22's was destroyed, and tossed in the Cobb County landfill, and all the people that built them are dead, retired, or working other projects locally. Might as well just work out the F-35 to cost less long term since they air frames are being build in Marietta, Ga before being shipped to Texas to be completed. F-35 has a trained staff working week in and out, and ready and willing to keep building F-35's long as they can, and all the equipment needed isn't under a few hundred plus feet of local landfill, or stored middle of bumfuck wherever it can get lost, so just make more F-35's since in the end, they seem to work good in the end. Just build F-35' still we get something like Stargate SG-1's F-303's flying? But F-22 while bad ass? I don't see a redo working. To many issues that would force you to start from nothing anyways. |

Buy 300 new F-15's as a stop gap measure as we await the F-22 replacement since the production line is still open. We need actual airframes to do the missions. Yes I know they're 2 seat models only but it's still the best thing available that's still being made It is not like a new, even better Eagle with modern avionics would have many credible threats against them. I just hate how we sell them like candy these days.....I hope we install some sort of kill switch on those. When the new F-22s start showing up again then you can retire all the A/C models and maybe some of the oldest Es. Supposedly the airframes on the E were so much improved though they can fly for years to come without the same issues with wing failures. 300 brand new F-15s will replace all of the F-15C models currently in service plus double the current F-15 strength if you don't include the Strike Eagles. Reactivate some Cold War squadrons and fill them up. Have the Navy buy some more Growlers and get the Marine Corps into the game since their Prowlers are going out to compensate for lack of stealth. |

My uncle said the next F-22 would be a B model or even a C model.

Tooling for bending and forging the big metal bits will still be around. Those aren't the problem. It's the thousands of other parts that aren't made anymore by companies that don't exist that were staffed by people who have retired, changed careers or have other jobs to do. You could make something that looks like an f22, but it'd have all new guts and that'd cost more then we are likely willing to pay for and take so long it'd probably not be all that relevant. Many of these suppliers have changed processes from the ones used originally - any time processes are changed, that's a significant hurdle to qual' that component for use on the aircraft. Maybe they could bring back the old process, maybe not? Maybe resurrecting the old process is more expensive? And now we are far enough along that design software obsolescence is a problem. You're talking about putting together two guys who are probably each two companies removed from their original contractor/vendor relationship. Currently, the program is in "sustainment". The folks working sustainment are top notch - most were there for production. But, bringing the aircraft back into production and flight testing is far bigger than just scaling up their skillsets. Congress's "vision" for restarting the F-22 is essentially stringing together enough funding to rehire/retask/relocate a bunch of engineers for about two years, at which point the decision will be made that it isn't worth it, and the restart will be terminated. Nobody is going to show up for A-12 part II. Put together a meaningful plan that either takes full advantage of the in situ mission system capabilities, or possibly take mission systems to the next level, and then you'd get more interest. Until then, it just looks like a road to nowhere, and you'd be a fool to hitch a ride down that path. tl;dr It's going to be very expensive to bring the aircraft back. Congress isn't going to commit to the proper level of funding to do so. At the first sign of cost overruns/schedule delays/mission creep, Congress will kill it. Congress will claim the moral high ground by saying they tried to do the right thing, but their job is hindered by stupid Americans who can't get their act together. Everyone who's BTDT sees where this is going. |

Why America Simply Can't Build Anymore F-22 Raptors
The Raptor’s avionics were dated even before the jet was declared operational in December 2005. While the Raptor is the most advanced operational warplane in the Air Force’s inventory, its computer architecture dates back to the early 1990s. The core processors run at 25MHz–since it took so long to get the jet from the design phase to production. Moreover, the Raptor’s software is particularly obtuse and difficult to upgrade–which is partly why integrating the AIM-9X and AIM-120D missiles onto the aircraft has been so problematic. The jet’s avionics would have to be completely revamped for a production restart, not just because they’re obsolete, but also because the jet’s antique processors and other components haven’t been made in decades. That would be a very expensive proposition at a time when the Air Force’s budgets are shrinking. View Quote |

I get that it would be expensive - but you have drawings, specs, working models, and you know it works. You have skilled manufacturers that know how to build / engineer critical hardware, even if they haven't built that specific piece before. It's always easier to recreate something that's been done before than it is to start over.
Difficult? - Sure. Expensive? Sure, but it has to be less than starting over since you have a working design and you don't have to repeat that phase of the project. Get military aircraft mfgs together that aren't working on the JSF and get it going if there is a need for it. |
