The SU-37 was the only standarised tracked self-propelled anti-aircraft weapon used by the soviets duing WW 2, although a number of lorries and improvised armored vehicals were also used. The SU-37 consisted of either a single (SU-37-1) or dual (SU-37-2) 37mm anti-aircraft gun (model 39) mounted in an open, rotating turet placed upon the modified chassis of the T-70 light tank. The weapon could elevate from -2 degrees to + 87 degrees.
This was an aromred vehical very similar to the Ostwind.
