The 12.8 cm Pak 44 (Pak from German Panzerjägerkanone "anti-tank gun") is a German anti-tank gun used during World War II. It was designed as a result of experiences on the Eastern front in 1943. The German Army came upon the Soviet 122 mm field guns and issued a requirement for a similar weapon. Development initially concentrated on a field gun known as the Kanone K 44. However, once heavier Soviet tanks such as the IS-2 started to appear, the design requirements were altered to include an anti-armour role.
The Pak 44 has short to medium-range performance similar to the 8.8 cm Pak 43, but the 12.8 cm Pak 44 better maintained its anti-tank performance over long to extreme-long ranges – 1,800–2,700 m (2,000–3,000 yd) and beyond - while also doubling as an effective field gun when firing high-explosive shells.
