Little known / experimental aircraft

If AI starts to make stealth less effective, then it is a return to speed. Perhaps one could use the Blackbird’s proven airframe to test new propulsion systems in the speed range between Mach 3 and hypersonics - which eliminates the problems of the old engines and special fuel.

Ummm...you know there is stuff out there that can intercept missiles now? And some of those missiles go a lot faster than any plane ever has, so a really fast plane isn't the invulnerable piece of kit it was 50-60 years ago.
 
Here is the YA-9, Northrop’s contender in the close air support role fly off.

The two aircraft were almost identical in performance, mostly because the AF was very clear on the specifications. Northrop selected the new (experimental) Lycoming YF102 engine for the YA-9 rather than the more powerful General Electric TF34 used by the A-10. Both flew well, and test pilots even reported the YA-9 had mildly superior handling, but the USAF went with the A-10 primarily because the GE TF34 was a known engine with a solid history.

Another fun entry, the test bed for the The Pratt & Whitney T34 (Turbo Wasp) was a B-17.

The engine was a Navy project but they passed on it. It ended up first of the Supper Guppy but primarily on the C-130’s daddy, the C-133 Cargo Master.

It always amazed me that form follows function re: it's SU-25 cousin!

While watching an episode of The Twilight Zone, the Royal Air Corps pilot takes off in 1917 but lands in 1959 at Lafayette Air Force Base in Reims, France.

The first aircraft stationed there was the recon / bomber Breguet BR-19. The lower wing was substantially smaller than the top wing. It carried 4 .303 machine guns: 1 firing forward, 2 controlled after and 1 that could fire downward.

A successful design, it set several airspeed and altitude records in the 1920’s.

The hulking Sikorsky H-37 had 2 Pratt and Whitney R-2800 2100 HP piston engines (think F-4U Corsair) in sponsons feeding into a central gearbox - one of the first true heavy lift helicopters with a max gross of 31,000 lbs. There is an excellent display at the superb Evergreen Museum in McMinnville, Oregon.

An experimental model HR2S-1W had an early warning radar and was easily recognizable.

I'm not a helo guy, But I have seen this bird up close and personal. What a beastly thing it is.

There's one outside on the ramp behind the Naval Aviation Museum along with the other aircraft they haven't restored or put on display yet. She looks a bit worn but otherwise fine, I wish some rich former Naval Aviator gave the museum a boatload of money to restore and put those birds on display.
