The Grigorovich TB-5 (Russian: Григорович ТБ-5) was an experimental heavy bomber designed and tested in the Soviet Union in the early 1930s.

Designed as a competitor for the Tupolev TB-3, the TB-5 was intended to be powered by two FED 24-cylinder X engines of 746 kW (1,000 hp) each.

When these were canceled, the underwing pods were revised to each house a pair of Bristol Jupiter engines in a push-pull configuration.

[1] Test flights began on 1 May 1931 with disappointing results, in part due to poor thrust of the rear-facing engines.

[1] The prototype TB-5 was wrecked in a crash landing following the in-flight detachment of an engine in the spring of 1932,[2] and with the entry into service of the superior TB-3 that year, the TB-5 project was abandoned.
