Nice collection. Another one worth viewing is the Soviet Union's version of an "Ekranoplan", a type of flying ship that uses the ground effect to effectively "float" a few meters above sea level.

The 242-foot, 400-ton MD-160 was the sole Lun-class Ekranoplan built by the Soviets [1]:

Edit: Here's a satellite photo of the Lun-class Ekranoplan shown above, at Kaspiysk (currently Republic of Dagestan, formerly USSR), from Bing Maps [Coordinates: 42.881692, 47.656986]:



I initially visited Google Maps, but couldn't spot it... Googling about it, I found out that on 31 July 2020 the Lun-class was towed from Kaspiysk to Derbent, Republic of Dagestan, where it will will be put on display at the (future) Patriot Park on the Caspian Sea [3], [4]. Google Maps must have recently updated their satellite images, and show the, now empty, dock platform.
