WR-40 Langusta

WR-40 Langusta is a Polish self-propelled multiple rocket launcher developed by Huta Stalowa Wola. The first 32 units of the WR-40 entered service in 2010.
The Langusta is based on a deeply modernized and reworked Soviet Cold War-era BM-21 launcher. The old petrol Ural-375D truck chassis was replaced with a modern one, and the launcher was fitted with a fire control system. The carrier used is Polish 6x6 Jelcz truck model P662D.35 with low-profile armoured cabin for the whole crew. Also new ammunition,, with a range was adopted.
The prototype was made in 2006 and given to the army in 2007, after successful trials. A series modernization of 75 vehicles followed.
Another step in the modernization of Polish rocket artillery is project 'Homar', corresponding to HIMARS rocket system, carried on from 2007.
