PP-64 Wstęga

The PP-64 Wstęga is a Polish military pontoon bridge produced since 1966.^[1] The design, based on the Soviet PMP model, commenced in 1964. The prototype was tested in 1965.^[1] Unlike PMP, rated for 60,000 kilogram load, PP-64 was rated for 40,000 kilograms, still sufficient to carry T-54/55 and T-62 main battle tanks of its period.^[1] Jane's Military Vehicles and Logistics staff supposed that PP-64 may also be capable of supporting T-64 and T-72 tanks.^[1]
