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.^[2] The carrier used is Polish 6x6 Jelcz truck model P662D.35 with low-profile armoured cabin for the whole crew.^[2][3] Also new ammunition, Feniks [d], with a 42 km (26 mi) range was adopted.^[2]

The prototype was made in 2006 and given to the army in 2007, after successful trials.^[2] 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.
