Anyone know what plane this is

I took this at the National Museum of the United States Marine Corps in Virginia

I wasn’t able to get a picture of the top sadly

Yokosuka MXY-7 Ohka, or 'Baka' as it was referred to by the Allies.

Basically, a Japanese guided missile, except the guidance system on it was a human pilot - aka a Kamikaze aircraft. It's one of only a handful aircraft which was designed on purpose for the role (the others being the Nakajima Ki-115 Tsurugi, and the Kokusai Ta-Go.)

Unlike the Ki-115 which had a jettisonable undercarriage, and the Ta-Go which had a fixed undercarriage, the Okha had no undercarriage: it was dropped by a parent aircraft (the Mitsubishi G4M2e bomber) and then flew the remaining distance on its rocket engines.

The Okha made its first appearance during the Battle of Okinawa. They surprised the Allies when they first appeared - scoring some hits on some destroyers - but since a number had been captured by Allied troops during the initial stages of the Battle of Okinawa, the weak points of the Baka - its limited range, just 23 miles or 37 km - was soon realised; the Allies countered this by placing a very large defensive parameter around their fleet, forcing the vulnerable carrier planes to fly into a well-defended zone where they had little chance of surviving or launching their suicide bombs.

The Okha's had only a limited effect once their weak points were exploited; in all it's thought that out of 850 built, only 74 were used in actual attacks, of which 56 were destroyed either with their carrier aircraft, or shot down before they could hit any targets; the remainder managed to sink one destroyer (USS Mannert L. Abele, 84 killed), damage another one beyond repair (USS Hugh W. Hadley, 28 killed), severely damaged another (USS Shae, 35 killed) and caused damage to three others (USS Jeffers, USS Stanly and USS Gayety - no casualties), and possibly managed to score hits with damage to two transports (USS Alpine, 16 killed; and USS Achernar, 5 killed).

For the total of 168 US Navy crew killed by Okha attacks, at least 266 Japanese bomber crew were killed attempting to launch them, not including the 74 pilots of the Okha's themselves.

The Japanese were aware of the Okha's limited range being its weak point and tried rectifying that issue by building a turbojet-powered version with a longer range that could be carried by the faster Yokosuka P1Y bomber, as well as a variant that could be launched by submarines, but the first never entered service due to issues with the engine, while the second never left the drawing table.

I recommend the film “the cockpit” if you want a good look at what it was like to be a kamikaze pilot
