In 1932 engineer GVF Sergei Ivanovich Komarov proposed modification of the ANT-9 wing to accommodate two M-17 engines like was done on the R-6. Aircraft was ready in 1933 and went into mass production under designation PS-9.

Approx. sixty built, served with GVF until 1943.

PS-9 served at short/medium lines all over the USSR. Accumulated flight time exceeded 5,000h, up to 2,000 flights per plane. During The Great Patriotic War PS-9 were used as military transports. All-metal construction proved its high reliability.

One PS-9 was modified into propaganda aircraft, named 'Krokodil' after popular satiric magazine. Reptylish nose was added, as well as spine spikes. Aircraft also differed from series PS-9 by airdynamic fairings on the wheels and struts.
