There are two ERAWA's modifications ERAWA-1 and ERAWA-2 differing in explosive's weight.Įxperiments showed that ERAWA dynamic defense decreases high-explosion stream proofing depth by 50 - 70 % and undercaliber projectiles - by 30 - 40 %. The main ERAWA's difference from Soviet analogs is that ERAWA's containers fit almost without gaps while on the Soviet modernised T-72 gaps reach 10 - 15 mm noticeably decreasing defense effectivity. PT-91 "Twardy" uses steel anti-cumulative screens instead of rubber used on T-72. 108 containers are placed on the turret, 118 on the hull and 84 on each sides anti-cumulative screens. This defense consists from 394 containers with explosives, detonating in case of direct hit. Main battle tanks defense from high-explosion projectiles and missiles is increased by new ERAWA dynamic armor developed by Poland Military-Technical Institute. In 1993 Polish Defense Ministry ordered 20 tanks PT-91 for polygon and Armed Forces tests. From base modification it differs in increased defense, fire control system and engine.
Modernized main battle tank got indexation PT-91 "Twardy" (twardy - rigid ). Starting from July 1991 T-72 modernization programs were made by "BUMAR" combinate which have been serially producing T-72 under Soviet license. After the end of Warsaw pact Poland had to modernize Polish Army main battle tanks on it's own. In the middle of 80-ties Poland faced Soviet main battle tank's T-72 "Ural" modernization and capabilities increasing problems.
