Why did Germany develop the Panther tank after encountering the T-34?

Germany developed the Panther tank (Pz. V) as a direct response to the combat superiority of the Soviet T-34 medium tank, which German forces encountered in late 1941.1

When German medium tanks like the Pz. III and Pz. IV first faced the T-34, they were completely outclassed by the Soviet vehicle’s lethal 76.2-mm gun, excellent mobility, and advanced sloped armour. Recognizing the urgent need to counter this threat, the German army initiated a crash program to design a new tank that would incorporate these advanced features.1

The resulting Panther tank featured:
* Advanced Armour: It utilized sloped armour to encourage shells to ricochet, with 80 mm of thickness at the front.1
* Superior Firepower: It was equipped with a long-barreled, high-velocity 75-mm gun capable of penetrating most enemy tanks at range.12
* Mobility: Despite weighing 45 tons, it was powered by a 700-horsepower engine and featured an excellent suspension system, providing it with high speed and effective cross-country performance.1

The Panther entered production in November 1942 and became a backbone of German panzer divisions alongside the Pz. IV for the remainder of the war.1
