Military inspector V.O. Shpakovsky examines a rare improvised 76 mm self-propelled gun based on the T-26 light tank during final inspection at the Kirov Plant in besieged Leningrad.

Leningrad, Autumn 1941.
As the German siege tightened around the city, Leningrad's factories adapted to wartime necessity with remarkable speed. One result was this rare improvised self-propelled gun, created on the chassis of the aging T-26 light tank to strengthen the city's desperate defenses.
Built on a T-26 light tank chassis with its turret removed, the vehicle carried a 76 mm M1927 regimental gun mounted behind a simple armored shield. It was neither elegant nor standardized, but it provided the defenders with much-needed mobile firepower at a time when every operational fighting vehicle counted.
These improvised vehicles appear under several designations in wartime documents and later historical literature, including SU-26, SU-T-26, and T-26-SU. According to surviving wartime records, no more than about twelve 76 mm vehicles were completed at the Kirov Plant during the Siege of Leningrad. Other conversions carried lighter armament, including 37 mm guns, but the 76 mm version offered significantly greater battlefield effectiveness.
Standing in front of the vehicle is military inspector V.O. Shpakovsky, conducting a final inspection before the machine entered service. These improvised self-propelled guns served with formations including the 124th and 220th Tank Brigades, and some reportedly remained in action until 1944.
The SU-26 stands as a reminder that the defense of Leningrad depended not only on factories and weapons, but also on the ingenuity of engineers and workers who transformed obsolete vehicles into effective fighting machines under siege.
