The Jagdpanther, Sd.Kfz. 173, was a tank destroyer built by Germany during World War II. The Jagdpanther combined the 8.8 cm Pak 43 anti-tank gun, similar to the main gun of the Tiger II, and the armor and suspension of the Panther chassis. The earlier G1 1944 model has a small welded main gun mantlet, one-piece Pak 43/3 gun, a modified Panther A engine deck, and had two vision openings for the driver. Some later G1 models had 'hybrid' G2 features such as the larger G2 mantlet as changes to the design were implemented. Zimmerit was applied to G1s up to September 1944, then was withdrawn to decrease production time.
