WR-40 Langusta [Crawfish] 122mm MRL

WR-40 Langusta is a Polish self-propelled multiple rocket launcher developed by Centrum Produkcji Wojskowej HSW SA. The WR-40 Langusta (Wyrzutnia Rakietowa) multiple launch rocket system is a modern upgrade of the Soviet BM-21 Grad artillery rocket system. 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 armored crew-cabin.

The first 32 units of the WR-40 entered service in 2010. As of January 2010. Polish Armed Forces had 19 pieces launcher, located on the equipment 5 artillery regiment in Sulechw (18pcs.), and Training Center artillery in Torun (1 pc.). In total, Polish army ordered 75 pieces launcher WR-40. After delivering the last consecutive launchers there would not be further orders.

The scope of the changes made in the BM-21M, as originally determined modernized under the program Crawfish launcher, were so big that ita was proposed to introduce a new marking system. Among several proposals accepted eventually WR-40 and the name Langusta. The first vehicle was donated to the Center for Training Missile Forces and Artillery in Torun. It is a Polish product made on the Polish chassis, the Polish armor plates and Polish electronics.

The first loading of artillery part and automated loading/ reloading system manually, by crew. Second loading of artillery part - by the automated loading/ reloading system, controlled from the cab or outside in less than 5 minutes.

Automatic artillery sets itself up on a position (azimuth and elevation) calculated by Fire Control System (FCS). Assisted artillery part is set up on a position (azimuth and elevation) by the internal (or external) control unit. Actual azimuth and elevation data are available on the control display unit. In the case of system failure, artillery part elevation and azimuth can be controlled manually (by means of handwheels).

New fire control unit PALBA (stationary and portable version), which control panel resembles that of the CZS family, enables firing of rockets in sequence or from a specific barrel (chosen by the commander). Moreover, the fire control unit keeps a record of loaded rockets (providing information for the commander which barrels are loaded). New impulse generator is also used to control firing operation (based on the KOMUT-10TA series).

Firing protection is provided by two hardware protection keys, which must be installed on the impulse generator unit (KOMUT) and fire control unit (FCS). Fire control unit can be connected to FCS software, enabling automated recording launched rockets.

The budget 2007 did not have the money to buy further copies, but guided by the HSW group of companies responsible for the modernization (Jelcz-Components, Electronics WB) intended to launch production of copies in 2008, this would allow the rearmament of the first rocket artillery squadron of the 2nd Regiment artillery. There were about 10 pieces to produce the final in 2007. The number of vehicles in the squadron was still discussed in the DWL, where the gunners were given the task of determining the optimal structure of the target squadron equipped with the WR-40.

The problem is that the WR-40 can do much more, even as a standalone car than the BM-21. WR-40 was placed on a modern chassis 6x6 high mobility Jelcz P662D.35 with armored (level 1 STANAG 4569), and protected against the effects of NBC weapons cabin crew 144 (project Jelcza). Equipped with a digital fire control system (WB Electronics) with a modern navigation system (Tallinn 4000) and the communication system based on radio VHF Radmor RRC-9311AP (Fastnet) and radio Individual PRC-500 working with Fonet (configuration Fonet BMS, with stitched system Trop battlefield management).

This and the use of missiles family of Phoenix-Z Factory Special Production Bolechowo made use of batteries and tactics squadron radically changed. Even the smaller unit can theoretically do the same job faster and more efficiently. In turn, the unit increased to 24 vehicles give commanders greater flexibility in the distribution of batteries (without substantial modification to the supply system. The quality of shooting is also reflected in the consumption of ammunition).

The first estimates mentioned the possibility of retooling 6-8 of the BM-21 squadrons with WR-40. And that meant buying 72 to 144 launchers, the real number is probably the range 72-108. One thing is certain: WL commander, gen. Waldemar Skrzypczak, is a supporter of rapid and comprehensive solutions, giving real growth of combat capabilities. He declared the performance of all purchases within 4-5 years, with an emphasis on the annual retooling 1-2 squadrons.

HSW was realistically able to produce annually 30-40 WR-40, the essential elemen of the scale production plant capacity is Jelcza. This does not mean the guaranteeing of increasing orders from the Ministry of Defence, it will not be increased. Gen. Skrzypczak announced that it would be interested in buying in 2007 the first 10 trucks with ballistic shields for the cabin crew. These would increase the security of logistics missions in Iraq and Afghanistan.

Langusta 2 is not in the army inventory yet, it was presented in the MSPO 2012 and the production is prepared instead of Langusta 1. Langusta 2 overall is more automated than it's predecesor, it is possible that old Langusta MRLS will be modernized to Langusta 2 standard. Another step in the modernization of Polish rocket artillery is project 'Homar', corresponding to MLRS rocket system, carried on from 2007.
