WR-40 Langusta is a Polish self-propelled multiple rocket launcher developed by Centrum Produkcji Wojskowej HSW SA. The first 32 units of the WR-40 entered service in 2010.

The Langusta is based on a deeply modernized and re-worked Soviet cold-war era BM-21 launcher. The carrier used is a 6x6 Jelcz truck model P662D.35 with armoured crew-cabin.

Another step in the modernization of Polish rocket artillery is project 'Homar', corresponding to MLRS rocket system, carried on from 2007.
