The Invisible Tank PL-01 Unveiled
Obrum, part of Poland Defence Holdings, has revealed its latest product, the Tank PL-01 CONCEPT at the MSPO 2013 defence exhibition. In cooperation with Polish companies and British conglomerate BAE Systems, the PL-01 which weighs 35 tonnes, measures 7 meters long, 3.8 meters wide and 2.8 meters high. Three people can fit in the hull of the vehicle. The Adaptiv technology protects the tank from detection. An array of hexagonal Peltier plates on the surface can be heated and cooled to project a desired image, such as the background and or a separate object, making the tank invisible. The tank is also equipped with a system of 350-degree continuous observation day and night. Comprised of a chassis with an unmanned turret that has an autoloading 105 mm or 120 mm caliber cannon, the PL-01 is intended to act as a fire support combat vehicle. According to Poland Defence Holdings, production on the PL-01 is expected to begin in 2018 with exports to take place in 2022.
