This Tu-2 S was built in 1947. In the mid-1950s, the airframe was rebuilt to facilitate tests with ejection seats and it was transferred to the Museum's collection in 1964.

The Tu-2 matured with this S model, propelled by powerful ASh-82FN radial engines. Built in 1947, this aircraft is said to have spent two years in Soviet service, before joining the Polish air force with serial 5. Among its variety of tasks was being an ejection seat test bed, for which it was modified in 1956. The museum received it in 1964 and has it on display with the rear cockpit restored as the gunner's place, but without markings.
