Military Aircraft that should have entered service

This thread is for military aircraft projects that should have been built and entered service, but were canceled for various reasons-whether political, financial, technical developments, or a war not going as expected.

My choices:

A-6F: This was the Navy's original choice for a viable medium attack platform, until they drank the Kool-aid of the A-12 Avenger II program. Even after the A-12 was canceled, the A-6F should have been revived to preserve the Navy's deep-strike capability. The Intruder II was a brand new aircraft, with new engines, avionics, glass cockpit, new radar, FLIR, ECM, etc. Too bad Dick Cheney as SECDEF had a vendetta against the New York Congressional delegation (Grumman would've built the A-6F at its Calverton, NY plant on Long Island).....

B-1A: the original Rockwell International strategic bomber. SAC wanted 241 of these, to replace the B-52. The Russians admitted they had no real defense against the B-1A, if Viktor Belenko's biography is correct, and they told SALT negotiators "You made a mistake in canceling this one." Unfortunately, it was Mr. Peanut (AKA Jimmy Carter) who canceled it, believing that not only B-52s with ALCMs, but also the B-2, could do the job. As we know, it was this decision (among others) that made many in his own party-not to mention the GOP, wonder if Carter was "Soft on defense."

YF-12/B-71: Not just the interceptor, but Kelly Johnson had a design for a bomber version of what became the SR-71. The interceptor could have been used not just for NORAD, but also in Europe, to take out high-value Soviet aircraft such as the Tu-126 Moss AWACS. Had the bomber entered service, it was likely to have been used as a "Wild Weasel" to kill SAM sites and interceptor fields to clear the way for the B-52s in a SIOP scenario. Supposedly, it was Lockheed's push for both variants being a factor in the Edsel Mechanic (MacNamara) deciding to stop SR-71 production at 30 airframes, cancel the YF-12 and B-71, and order all the tooling, jigs, etc. destroyed.

P6M Seamaster: while its intended mission of nuclear strike would have been taken over by Polaris SSBNs, the aircraft could have easily been reroled as a Maritime Patrol and ASW aircraft. It was kicked around at Martin prior to cancellation.
 
Mine is the Curtiss P-40Q
PZL P. 50
The Il-40 "Brawny" Ground Attack Plane
The Il-16, which was an improved variant of the Il-10, but to be fair, was developed during the time when Jet aircraft were starting to take over.
Martin Baker M.B. 5.
Heinkel He-100 - Despite being on par with the Me-109, was not built due to Heinkel not having any capacity to built any due to He-111 production.
 
Agreed on the A-6F being a very stupid cancellation(one which should have ruined Cheney's political career if there were any justice in the world of defence procurement) as retiring the Intruder without replacement left a massive hole not just in long range striking power of the carrier air group it also retired the Navy's dedicated airborne tankers an ability that the USN still hasn't recovered(albeit it will be doing so in the foreseeable future)right before the war on terror kicked off and resulted in carriers hitting targets further inland than ever before which resulted in the navy wearing out the S-3 Vikings in order to use them as tankers and retiring them without replacement as well, and the fleet currently is wearing out its Super Hornets faster than expected because of the need to do lots of buddy tanking sorties. Sure the A-6F would be aging and in need of replacement by a more stealthy aircraft starting around the present date but a critical hole in capabilities wouldn't have occurred at the worst possible time

I disagree in Martin Seamaster, but raise you one Budd Conestoga transport.

Martin Seamaster was super sonic and far too thirsty for long ASW patrols.

OTOH Budd’s Conestoga was the first WALLIED transport with a cargo ramp under the tail. Granted, Conestoga Mark 1 were slow and had maintenance issues, but those would have been solved by the Conestoga Mark 2 and Mark3. The tail ramp had the potential to revolutionize airborne assaults and re-supply by air.
If you hop forward a decade and two, you will notice that the primary difference between the French loss of Dien Bien Phu compared with USMC success at Khe Sangh was primarily due to ionly a few C-47 Dakota’s and a handful of CIA C-119 Flying Boxcars. Boxcars arrived too late to turn the tide of the siege.

OTOH Dien Bien was re-supplied by large fleets of of C-123 Providers, C-130 Hercules and DHC Cariboo transports, all with ramps under the tail to speed unloading on the “hot” airstrip at Khe Sangh.
 
The SeaMaster was not supersonic. The Convair F2Y Sea Dart (the seaplane fighter meant to defend Seamaster bases and for escort) was, however.
 
This is where I get to say He-100D (not the evaporation cooling dependent one).
Would beat the Bf109 in climb, speed, range, loiter time and production time.
 
The Super Tomcat would have been great if produced.
The other one I wish they had built was the FB-22 proposal.
Now I know Helicopters are usually not included but the LHX or RAH-66
 
Some non-Western aircraft.

1. The Xian H-8. Basically a Chinese B-52.
2. The CAC/Grumunn Sabre II. An advanced J-7.
3. The Tu-80/85. The ultimate expression of the B-29 family.

During a discussion about Super Tomcat variants I heard that finishing development and procuring those was cheaper than going for the Superbug. Planned upgrades would have reduced the high maintenance costs too.
 
Super Tomcat, Goster F.5/34, He 100, MiG-3 with AM-38 (two prototypes flown historically), ANT-58 & -59 (predecessors of the Tu-2 with Mikulin engines), AH-56 chopper, Sukhoi S-56, F-20.

He 100 was better than on par.
It was faster (RLM tried to falsify results so Heinkel would lose, they apparently had beef with him), had 2x the range, and one prototype had 4x MG 17s and 2x MG FFs

The B-39 Superfortress. Or, more exactly, instead of the balky and troublesome R-3350, they should have planned on using the V-3420 liquid-cooled engine from the start of the program. Based on the limited testing done, the B-39 probably could have been available earlier and, crucially, with fewer teething problems than the OTL B-29. It would also have freed up production capacity on the R-3350 to be used for other aircraft (whereas the V-3420 was used for...well, nothing, in the end).
