ZSU-37Self-propelled anti-aircraft gun, based on the SU-76.The unrelated
SU-76i (1943) was based on the German
Panzer III and
StuG III chassis, armed with a
ZiS-5 76.2 mm gun. About 200 of these captured vehicles, many from
Stalingrad, were converted at Factory No. 38 by adding a new enclosed superstructure. They were issued to tank and self-propelled gun units starting in autumn 1943.
[2] They were withdrawn from the front in early 1944, and used for training until the end of 1945.

The also unrelated
SU-76P (1941) was based on the
T-26 chassis. it was built in Leningrad during the
Siege of Leningrad and involved removing the turret from the T-26 and mounting a
76 mm regimental gun M1927 on the engine deck. This was created due to the lack of high explosive 45mm ammunition inside Leningrad due to the siege, so some T-26 tanks were rearmed with 37mm or 76mm guns for which a reliable source of ammunition was available. They served until 1944, when the siege was broken. They were originally called SU-76, until the SU-76 came into service, upon which it was renamed SU-76P ("polkovaya" - regimental).

In 1978, Institute 111 from Romania designed an armoured personnel carrier based on the SU-76 chassis, equipped with the
TAB-71 turret. The vehicle entered service as the
MLVM (
Romanian: Mașina de Luptă a Vânătorilor de Munte, meaning "infantry fighting vehicle of
vânători de munte").
