The T-17 tank was a one-man "mechanized support" tankette designed and developed by the Soviet Union during the Interwar period.

In 1926, the design bureau КБ Orudiyno-Arsenalny Trest, OAT (later OKMO) began work on a "Liliput" single man light reconnaissance tank.

On March 3, 1928, under the leadership of the head motor lab, AP Kushka involving LY Lalmena, as well as engineers, Semyon Ginzburg and Edward Grote undertook the production of a new draft.

The Ustay enunciated the aim of conducting deep battle to achieve success in penetrating the tactical depth of enemy defenses.

The superstructure, which sat atop the chassis of the T-17 (often referred to as, like its predecessor, "Liliput"), was riveted to the frame.
