The Ilyushin Il-10 entered service in the Soviet Air Force in 1944, and became the standard ground attack plane for the Warsaw Pact. Communist China received 254 Il-10s, which served in the Assault Aviation Divisions of PLAAF.
But by the late 1960s these plane were becoming increasingly obsolete. So to extend the life of the Il-10, the PLAAF decided in 1969 to put an turboprop engine in the old airframe. Two testplanes were build. But time was up for the old planes, and in 1972 the Nanchang Q-5 Fantan jet fighter-bombers entered service.
But what-if the development of the Q-5 ran into troubles, and the beefed up Il-10s entered service.
My build will be based on a Kovozavody Prostejov kit from the 1970s, which I picked up in another century in what was then know as Czechoslovakia.
