The Yokosuka Tenga (天河, "Milky Way") was a proposal to provide the Imperial Japanese Navy with a jet-powered bomber towards the end of World War II.
The concept was to replace the piston engines of the Yokosuka P1Y1 with turbojets.
[1] The powerplant selected was the 8.34 kN (1,870 lbf) thrust Ishikawajima Ne-30 then under development.
However, before a single example could be built, both the Ne-30 project and the Tenga were cancelled due to technical difficulties with the turbojet design.
