The Leopard 2PL is a main battle tank used by the Polish Armed Forces, and is a modernized version of the older Leopard 2A4 tank, phased out by Germany and first acquired by Poland in the 2000s. The modernisation is currently being carried out in cooperation with Rheinmetall and the Polish Armaments Group (). History When the Land Forces took over the first Leopard 2A4 tanks from the Bundeswehr's resources in 2002, it was realized that their modernization was a necessity, but the first works on the development of the plan and the scope of their modernization started only in mid-2012. then developed the initial requirements for the modernization of Leopard tanks. The program was called Leopard 2PL. As a result of the conducted works, two variants of modernization were defined. The first one, basic, included the introduction of an electric turret drive and gun stabilization (in place of hydraulic one), installation of the APU, modernization of the optoelectronic system through e.g. installation of new thermal Imaging cameras, modernization of the driver's seat and a new anti-explosion, fire and mine protection package. The second, more extended variant, in addition to the works proposed in the first modernization version, was extended to include the BMS combat management system, installation of a remote-controlled shooting module on the turret of the tank, new types of ammunition, air conditioning systems in the driver and combat compartment, and modernization of the electronics cooling system. Finally, modernization program was included in the "Technical Modernization Plan of the Polish Armed Forces for 2013-2022" () in December 2012. At the beginning of March 2013, invitations were sent to interested parties regarding the technical dialogue, which was carried out from March to August. In October 2013, a tender was announced to select a contractor for the program. Three bidders: a consortium consisting of Wojskowe Zakłady Motoryzacyjne from Poznań, Wojskowe Zakłady Łączności Nr. 2 and Rheinmetall Landsysteme GmbH; Consortium Zakłady Mechaniczne Bumar Łabędy, OBRUM company and Polski Holding Obronny (PHO) and the last consortium consisting of PCO and ASELSAN Elektronik. However, the final offer was submitted by the consortium of Zakłady Mechaniczne, OBRUM and PHO, thus it was with them that the Armament Inspectorate started negotiations. The foreign partner was Krauss-Maffei Wegmann. In December 2014, the consortium submitted the final proposal based on the solutions of the foreign partner, but in 2015 the procedure to select the contractor was terminated
