A really interesting vehicle I found while going thru the files
Ok... So it was 1933, a guy named Aleksandr Moskalyev came up with a design of a rocket-powered, tailless aircraft with an ogival or gothic delta wing, wingtip fins and rudders, which would theoretically be able to fly faster than sound. But Because no sufficiently powerful engines were available at the time, the Moskalyev SAM-4 Sigma never left the drawing board but it did lead to two interim types, which is the SAM-7 Sigma and SAM-9 Strela.
Anyways the stats
Maximum speed: ~500 km/h
Range: 800 km
Service ceiling: 9,200 m
Landing speed: 138 km/h
