In keeping with mechanized warfare doctrine developed from Soviet traditions of World War 2, the Polish Army has carried over the use of wheeled Multiple-Rocket Launch System (MLRS) vehicles in developing its indigenous WR-40 "Langusta" series - this based on the existing successful family of Cold War-era BM-21 vehicle. The WR-40 entered service with Polish Army forces in 2010 and several dozen have since been delivered as of this writing (2012). The WR-40 will undoubtedly feature in any direct combat actions of the Polish Army concerning conventional warfare.

The design of the vehicle follows in line with previous Soviet offerings in use of a heavy industry, six-axle truck (the Jelcz P662D.35 6x6) complete with an armored cabin for the crew and an integrated flatbed mounting a pivoting rocket projecting system. The vehicle weighs in at 18.74 tons, sports ten off-road rubber-tired wheels and fires 40 x 122mm rockets within seconds of activation. The rockets are seated in individual launch tubes in a four-tube-high and ten-tube-across arrangement. The mount allows for traversal to engage targets at varying angles and elevates to clear tree lines, hills and buildings as needed. The armored crew cabin (which houses the driving and launch controls) is protected by small arms fire (including windows) through its steel fabrication process and multiple rectangular doors allow for quick entry/exit of the crew. A typical launch crew consists of four personnel. A resupply vehicle is required for reloads.

The vehicle is powered by an Italian Iveco Aifo Cursor 8 EURO 3 series engine of 347 horsepower. This supplies the WR-40 with a top road speed of 53 miles per hour and an operational range of up to 400 miles. The 6x6 wheel arrangement allow for cross-country capability and the high clearance of the chassis aids in traversing shallow water sources.

The WR-40 is the product of HSW S.A. (Huta Stalowa Wola) of Stalowa Wola, Poland. The concern has been in business since 1938 serving the steel industry and became such a success that the town of Stalowa Wola formed around the mill facility itself. The concern also produces the modern 155mm "Krab" self-propelled howitzer for the Polish Army.
