The PP-64 Wstęga is a Polish military pontoon bridge produced since 1966.[1] Design, based on Soviet PMP model, commenced in 1964, prototype 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]
PP-64 set consists of 48 truck-mounted pontoons, 12 ramps, six motor boats[1] (carried on twin-axle truck trailers)[2] and other equipment.[1] KH-200 bridging boats used with PP-64 were actually put in production later, in 1971; each is capable of carrying 15 troops.[2] Human complement in the field reaches 126 soldiers (including 60 Star 266 truck drivers) and 10 NCOs.[1] PP-64 allows assembly of three possible roadway combinations:[1]
| Length, m | Width, m | Capacity, kg (gross/axle) |
Max. river flow, m/s |
|---|---|---|---|
| 186 | 4.35 | 40,000 / 12,000 | < 1.2 |
| 145 | 4.35 | 40,000 / 12,000 | < 2.0 |
| 97 | 8.7 | 80,000 | no data |
As of July, 2009, PP-64 remains in inventory of Polish Armed Forces.[3]
