7.5 cm Pak 39 (L/48) (7.5 cm Panzerabwehrkanone 39) was a 7.5 cm German Second World War era AT (Anti-Tank) gun. The gun was used to equip SdKfz.162 Jagdpanzer IV/48 and SdKfz.138/2 Jagdpanzer 38(t) "Hetzer" tank destroyers; no towed version of the weapon was made. The Pak 39 was an electrically fired weapon fitted with a semiautomatic breech mechanism and a 48 caliber barrel. It was a formidable gun, able to destroy the most common allied tanks from up to 1,000 meters. It used the same 75 x 495R ammunition as the 7.5 cm KwK 40 of Panzer IV and 7.5 cm StuK 40 gun fitted on the Sturmgeschütz-series assault guns. The Pak 39 was manufactured from 1943 onwards by Rheinmetall-Borsig AG in Unterlüß and by Seitz-Werke GmbH in Bad Kreuznach. The main types of ammunition used were: Panzergranatpatrone 39 (APCBC), Sprenggranatpatrone 37 (HE) and different versions of the Granatpatrone 39 HL (HEAT).
