P-40 “Long Track”
The P-40 “Long Track” (Russ. Designator: 1S12 “Bronja” - the armor, cyrillic 1С12 «Броня») is a mobile radar station on the base vehicle 426 U with a range of about 300 km. The crew consisted of 6 men. It was used for target assignment for units of NVA troop air defense.
A diesel engine with 12 cylinders was used with a performance of 342 kW (465 hp). The radar station reached a maximum speed of 55 km/h despite an equipment weight of 35 t.
The electronic components of the receive path dates predominantly from the P 37.
The radar was powered by a built-in 400 Hz generator driven by a gas turbine.
