Already posted this in a different thread, but also fits here. Tank concept between the USSR, USA, Germany and France, but went no-where. (Yes it’s declassified)

Here’s a fun one: Hawker P.1030.

Hawk1030side

Functionally, a Hawker Tempest redesigned to take the Rolls-Royce Eagle 46H eagle making ~4,000 hp+.
It was expected to be able to reach a top speed of 508 mph/819 kmh at 6,069 m with an eye-watering climb rate of 1951 ft/min or 32.51 m/s.
There’s a thread on the Secret Projects forum that has a bunch of interesting info on it, and it’s one of my personal favourite prop designs.

Ah, a man after my own heart.

Always loved the craziness of this thing.

14" of composite on all sides for an equivalent of 26" steel. Vertically launched swingfires in the middle, and 2 mgs you can’t access to reload.

Oh, and a mobility of no.

Another insane product of the minds at Warton the P.1226
p1226

There’s also the various IKV-90 designs, I forget where but I saw a picture of all the drawings.

The Natter? I was thinking the same thing.
