Heres a somewhat unclear pic of a late 1960s Republic fighter design. It seems to connect back to the Republic F-108 but also shows some similarities to the Fairchild-Republic TFX submission. Anyone got more?

I hope every gets as thrilled as I do when I see posts like this. This is fantastic. Thanks Overscan.
 
Great find! Thanks.
(oh..sweet nostalgia)

A. It's in the fuel truck.
B. It's in the air-refuelling tanker.
C. It's in the external tanks but they made the plane too heavy for VTO.

:D
 
Is that area behind the cockpit the fuel tank? Considering the efficiency of jets and VTOL in general, it would need it's first refueling around the time it transitions to horizontal.

Behind the cockpit, and part of the tailcone. It also *seems* to indicate that the wing and vertical tail are also fuel tanks, but since that includes the actual control surfaces, that must just be a trick of the shading.
 
Here are some pics of the AP-100 in development tests from one of my 16mm films - hope you enjoy!

Very interesting shots! Thanks for sharing.

...Better still, any chance of capping the film and putting it on YouTube?

I just purchased all these films about 2 weeks ago and believe me it takes a lot of time to go through them all. I will copy some of them and sell most of them eventually. All in all I have about 1,000 films to go through and most of them are on film cores of varying sizes from 25 ft to 2,000 ft! They belonged to a former employee of Republic Aviation who rescued them years ago from being tossed when they were shutting down the plant. Most of the films date from the late 1950's to the 1960's along with some footage of the last project they were working on called the T-46A. For now though I'll just share some pictures I come across which I think this forum might find interesting.
 
Here are some pics of the AP-100 from an animated film I looked at. I have yet to find anything else showing a real mock up of this fighter.

I doubt it went any further than scale models, personally. Nice pics though, thanks for sharing, and enjoy digging through what you have ;)
 
Added to existing topic. Video was transferred from film and uploaded by forum member "Reelarchives".
 
Image quality is outstanding. Congrats to Reelarchives!
 
Republic AP-100A factory display model, ca.1957 (one of my favorite models!) This is the final configuration, with the little pitch fan in the tail.

I wonder how speedy this thing would have been on the deck. B)

With six J-85 turbojets and a L/W ratio >1, I assume Republic's Mach 2+ claim was easily attainable. But with those same six turbojets and little space left for fuel tanks, it's doubtful the AP-100's combat radius was anything to get excited about. Then again, the idea of a VTOL interceptor was to base it very near the front lines (i.e. the border between the GDR and the FRG).

Omigod... Such a beauty!! Thanks A LOT for sharing this marvel.

Though not specified, I would assume Mach 2 performance was at altitude. Attached is another view of the Republic AP-100A, showing the scalloped turbojet exhaust, twin-fin layout and rear pitch-control fan (which replaced the earlier puffer jet arrangement).


I wonder if Alexander Kartveli also designed the 1960 Cadillac Eldorado ...

6x J85s... Today we could replace that with 6x afterburning Williams FJ44s, though I'd remove the middle lift fan to use as a bomb bay and just use a 3-bearing nozzle like the F35.

Well, where would the three-bearing nozzle be located?
