The Leopard 2PL is a tank used by the Polish Armed Forces, and is a modernized version of the Leopard 2A4 tank first acquired by Poland in the 2000s. The modernisation is currently being carried out in cooperation with Rheinmetall and the Polish Armaments Group.
History
On December 28, 2015, an agreement was signed between the Armament Inspectorate and a consortium consisting of PGZ and Zakłady Mechaniczne Bumar-Łabędy for the modernization of 128 Leopard 2tanks with an option for another 14 units. The German partner of the consortium was the German company Rheinmetall Landsysteme, which in the past co-produced Leopard 2 tanks. The contract amount was 2.415 billion PLN. On June 20, 2018, an annex was signed using the option to upgrade 14 tanks, i.e. all Leopard 2A4 tanks used by the Army. The cost of the contract increased to 2.721 billion PLN. The contract originally assumed that all copies of the base order would be transferred by 2020 and those from options for 14 machines by 2021. The original work schedule assumed that the entire work process would be divided into five stages. In the first stage for 2016, preparation of all infrastructure and resources needed for modernization were anticipated. The second stage predicted that from November 2016 to the end of 2017, dismantling of the machines and preparation for the modernization process would be carried out, while in the third stage, falling in 2018, technology transfer and staff training on a trial batch of tanks. From June 2018 to March 2019, the process of starting production and delivery of the pre-series machine to the recipient was to begin, and the last fifth stage lasting from January 2019 to November 2020 was to begin serial modernization of machines and deliveries. However, the original modernization process envisaged that the prototype in the number of one piece would be delivered by the third quarter of 2018, the test batch in the number of 5 pieces made in Germany would be delivered by the end of 2018, the test patria comprising 12 machines already completed in Poland, it will be delivered by the end of the first quarter of 2019, and serial production of the other machines under the basic contract is to be carried out from the second quarter of 2019 to the third quarter of 2020. On February 18, 2016, a detailed agreement was signed with a German partner, which specified the terms of cooperation between ZM Bumar-Łabędy and Rheinmetall. The contract assumed that the German company would be responsible for: developing the tank modernization project, preparing the necessary technical documentation together with Polish partners, making a prototype of the 2PL version car and tanks of the trial batch, providing ZM Bumar-Łabędy with the necessary technical support in starting production of serial wagons, providing necessary tools and transferring know-how technology. During the Eurosatory 2018 trade fair, representatives of Rheinmetall announced the completion of factory tests of the Leopard 2PL prototype tank. In August 2018, the vehicle was sent to the Military Armored and Automotive Institute in Sulejówek, where it underwent further national tests in Poland. In 2018, Reinmetall handed over to ZM Bumar-Łabędy the first pre-series copies, which opened the way to the modernization of machines already in Poland, after the positive completion of testing the prototype vehicle. The prototype tests were prolonged, which influenced the modernization of further copies and their delivery to the recipient. During the prototype testing there were also problems with the chassis, the repair of which prolonged the testing process, which meant that serial production could not be started. The prototype was completed on May 8, 2020. On May 28, 2020, the Polish Land Forces received the first copies from the pre-series party. The contract was extended until the end of July 2023. The contract was annexed five times, this was mainly due to not taking into account the restoration of efficiency of some tank elements, which turned out to be necessary and the different state of wear of individual copies. The final cost of the program increased to 3.29 billion PLN.
Description
Leopard 2PL is a third generationMain Battle Tank, made in cooperation with Polish Armaments Group and Rheinmetall Landsysteme. The tank is designed to master and maintain the area, and support fire from deck weapons of mechanized and motorized subunits, in all weather conditions, both during the day and at night.
Armor
The modernization of the Leopard 2A4 to the 2PL standard includes the strengthening of the ballistic resistance of the tower to a level exceeding that of the machines in the Leopard 2A5 version. Additional external armor modules are mounted around the vehicle turret. It was not decided to reinforce the hull and vehicle chassis due to the significant increase in vehicle weight and cost reduction. Special anti-splinter liners have been installed inside the vehicle to protect the crew inside the vehicle against splashes and armor fragments in the event of a puncture or hit.
Armament
The main armament of the tank remained the Rheinmetall Rh-120 smoothbore gun in the L/44 version, but it was modified to adapt to the use of new types of ammunition, i.e. DM63 armor-piercing shell and programmable DM11 ammunition. Left and right resistors, return, recoil indicator and container for shell bottom were replaced, in order to use DM11 ammunition, a programming system was introduced in the cannon's falling-block action, as well as a fire control system and electronic cannon trigger assembly. A new on-board computer was installed with new ballistic tables. MG-3machine guns were not exchanged for another model. The gun stabilizer system of the cannon and turret drives were changed from hydraulic to purely electric.
Optics
The gunner's sight and sights of the gunner and the commander were modernized by adding Polish thermal imaging cameras of the third generation KLW-1 Asteria made by Polish PCO. Driver awareness has also been improved by installing a KDN-1 Nyks day / night reversing camera also PCO production. A monitor-control panel for the commander was installed, which enables: alternative image transmission from the modernized EMES 15 sight and PERI R17A3L4 CP instrument and performing a full test of tower systems in cooperation with the modernized RPP testing block and control of tower systems from the level of the commander, which allows operation in hunter-killer mode.
Communication
A new, digital communication bus was used. The radio has not been replaced by modern model.
Other
Tank propulsion units were subjected to general repairs, an auxiliary power unit with a power of 17 kW was installed, in addition to the installation of anti-shrapnel liners, crew safety was improved by the use of an explosion-proof system with cylinders with Deugen-N extinguishing agent and the fire system was modernized by adding a new control panel and cylinders with extinguishing agent, additional transport baskets were mounted outside the tower and adaptation of the evacuation equipment to the tank combat weight increased to 60 tons.
