The Shpitalny Sh-37 () was the first indigenous Soviet aircraft cannon, designed by Boris Shpitalniy at OKB-15. The gun saw limited production and was installed in few aircraft before being replaced by the competing Nudelman-Suranov NS-37 designed at OKB-16. It was installed on a military-trial basis on two short series of aircraft. Installed through the engined block of the Yak-7-37 it was known as MPSh-37, where "MP" stands for "motornaya pushka". As installed in the underwing gun pods of the Il-2 it was known as ShFK-37 ().
