This is one might what if, this will wreak some serious havoc on the US and European aerospace industry. More than 4000 thousand F-16 models to fill the shoes of! To stop the F-16, the "Reformers" must be stopped as well, which also has its own special butterflies. The Reformers were a group of civilians and officers in the DoD that felt that high technology was crippling the Air Force and a larger number of less sophistacted equipment would perform better. Just as the small, outdated MiGs had so frutrated the mach 2.0 F-105 and F-4 over Vietnam. John Boyd, Pierre Sprey, John Riccioni etc. would have to never get the attention of the Civilian staff in the Department of Defense. Without civilian support they would have never been able to run the Air Combat Fighter program that resulted in the YF-16 and YF-17 or the A-X program that featured the YA-9 and YA-10.
THE FATE OF THE US AEROSPACE CONTRACTORS:
McDonnell Douglas
Without the F-16 stealing production numbers, the F-15 goes on to be produced in larger numbers. However difficulties with the F100 turbofan means the headaches will remain in early service. The nominally "not a pound for ground" F-15A/B sees air to ground weaponry mounted much earlier than in the original timeline. The F-15 becomes the spiritual successful to the F-4, albeit in smaller numbers, and expierenced vast mission creep (air interdiction F-15C/D, reconnaisance F-15E, wild weasel F-15G). Because it was built in such large numbers it becomes cheaper and a more accessable export item. No F-18 Hornet is ever developed, McAir becomes a small player in Naval Aviation after losing the VALX competition (A-7 replacement) to Rockwell's North American division. Marines A/V-8 history stays largely the same as the OTL, but the A-4 soldiers on longer without the introduction of the F-18.
General Dynamics
The Fort Worth division is in a great deal of pain after their Light Weight Fighter concept does not receive funding and the F-111 production line. General Dyanimics scales back the division after failing to win the F-117 contract. Plant 4 is given a second breath of life after the Texas congressional congregation comes through with an order for new F-111H's powered by the F101 engine. They will replace the cancelled B-1A as a regional nuclear bomber and fulfil the Air Force's Enhanced Tactical Fighter requirement to conventionally smash the Red hoard coming across the fulda gap. No original F-15E timeline built.
Northrop
Tries to sell its P-530 design (similar to the YF-17) to foreign militaries but without official US backing its a tough sell. Nortrop then develops an F-5 model with LERXs and wing borrowed from the P-530 in 1978. This F-5G goes on to be a moderate export sucess with nations that had bought the F-5A and other third world venues. No YF-17, F-18L or F-20 in this timeline. The Northrop B-2 history stays the same as the OTL.
Grumman
Without the F-18 being developed, the proposed variable geometry F-4 and navalized F-15 fail to generate enough inertia to reduce F-14 production numbers. The F-14 enters Navy in 1973 and Marine service in 1975. Iran orders 80 F-14Bs in 1976, without having to bail out Grumman this time. Only 40 of the B's are delivered by 1979the F-14s are then purchased by Canada in 1979 after the Iranian revolution. After a string of high profile crashes due to the TF30, in 1976 the F101 Derivative Fighter Engine is funded to re-engine current and future F-14 models on the condition that it will be used in the VALX program. A-6, EA-6, and E-2 keep with the OTL.
Rockwell Internation
The B-1 is never resurrected due to the production of the F-111H in 1978. The Navy instead of focusing on the Sea Control Ship and VTOL aircraft sends out an RFP in 1976 for an single engine A-7 replacement with better attack ability than the A-7 and with speed/agility/IR suppression to avoid enemy sams at low level, the VALX. Rockwell wins this competition with a design that is a air-to-ground oriented HiMat. First flight in 1979 and the A-9A is introduced into the fleet in 1982. Rockwell still plays a major in Space exploration with the Shuttle and Rocketdyne.
Lockheed
Without the A-10 the Army was able to get the AH-56 through a congressional minefield and put into production. It proves to be very popular with pilots and Army brass but questions about survivability linger, production continues through the 1980s. Lockheed is also successful in attempts to get the X-27 funded for high speed test research. In Lockheed sets up co-production agreements with some of the original F-104 consortium and Asian nationas like Taiwan and Korea to build the CL-1200 Lancer. The Lancers are know for their phenomal acceleration and deadly slash attacks with ASRAAMs and AMRAAMs. It is given the designation "F-16" after a handful are bought by the US as agressors. F-117 development stays as it did in the OTL.
Vought
A-7E production is extended to meet fleet demand until the A-9 is introduced. However, Vought ceases to be a primary aviation contractor after losing the VALX program. The A-7D is never dethroned from the top of TAC air's CAS heep by the A-10 and continues to serve on with distinction. In 1982 the USAF contracts Vought to rebuild 400 A-7A/B/Ds into A-7F Strikefighters after the concerns of the survivability of non-afterburning aircraft are aired. The A-7F uses the F100 turbofans, more fuel added by a fuselage stretch, a modifed wing for shorter take offs, and a head mounted sight system slewed to the radar and targeting pod. This is Vought aircraft's last production model.
Fairchild-Republic
Without the A-10 and the loss of the F-15 contract, Fairchild closes the Republic division on Long Island and does subcontracting work for the civilian aerospace industry.
Boeing
Largely unaffected since its LWF candidate never made it to the final round and did not win any other major airframe contracts. Continues with its missile and helicopter divisions.
Hughes
The AH-64 is arrises due to the survival of the AH-56. Hughes Helicopters also looses out to Sikorsky's entry in the UH-60 competition, and focuses more on the civilian market but is never sold to McDonnell Douglas. AIMVAL/ACEVAL never takes place and the AIM-95 goes into joint service after much cost overruns in 1978. The AMRAAM ends up being a larger sparrow sized weapon with greater range. The miniturization problems ran into by the original AIM-120 are less of a problem and the missile enters service in 1986. The AGM-124 WASP survives the axe and goes into production in 1987.
Pratt and Whitney
Continues providing engines for the F-15 and A-7 after receiving much antagonism from the Air Force over the F100 program. They straighten up after the F101 threatens their market share.
General Electric
F404 is never developed, instead replaced by a high bypass YJ101 which goes on to power the F-5G, Grippen and F-117. The F101 becomes a successful fighter engine when introduced into the F-14 and goes on to power the F-111H, Lancer, the VALX.
I'll be foreign aerospace and export in depth later.
