Rak Self-Propelled Mortar
The Rak (Crayfish) is Poland's indigenous self-propelled 120mm mortar system developed by HSW and PCO, mounted on a modified BWP-1 (BMP-1) tracked chassis. It features an automated turret with the 120mm smoothbore mortar, computerised fire control with inertial navigation, and can fire standard and rocket-assisted projectiles to 12+ km range. Rate of fire is 6-10 rounds/minute. The automated loading system allows the crew of 4 to operate entirely under armour. Poland operates the Rak in battalion mortar batteries as organic direct support, replacing towed 120mm mortars. A future variant on the Borsuk chassis is planned for improved commonality.

SIGN INProtection level against contemporary ATGM threats is the defining metric here, and these figures hold up well.
The vertical launch capacity here provides mission flexibility that single-role warships simply cannot match.
Active protection system integration at this weight class represents a significant leap in survivability calculus.
