First flying on 8th May 1945, the first of two such aircraft was destroyed a few days later by an American air raid, whereupon all production was cancelled. There was talk of powering the second aircraft with Mitsubishi Ne-330 turbo jets but nothing came of it.
The power plant was as noted was in fact two coupled Aichi Atsuta developing 1,700 h.p. each

According to some sources the Me509 was built and shipped to Japan. The R2Y1 is an enlarged development of this. The Me509 was a development of the Me 309 with the engine and cockpit transposed. The was a second incomplete protype at the end of the war with two jet engines in mid fuslage and of course no prp which was designated R2Y2.

The second R2Y prototype was actually not earmarked for completion as the R2Y2. The R2Y2 had yet to progress beyond the design phase when the Japanese surrendered.

This aircraft is a modified version of the unbuilt Me-509 that had tricycle landing gear and mid mounted engine.
