The Panzerkampfwagen V Panther was a rushed answer to the Soviet T-34, whose wide tracks and sloped armor stunned the German army during Operation Barbarossa in 1941. After Heinz Guderian's commission studied the T-34, Daimler-Benz proposed a diesel, leaf-spring design close to a copy, which Hitler initially favored. MAN won because its traditional layout could use an existing Rheinmetall turret and save months. A 30-ton specification grew to nearly 45 tons as Hitler and the high command demanded 80 millimeter upper front armor and a 100 millimeter turret front. A shortage of gear-cutting machine tools replaced the planned planetary steering gears with a double spur system that stripped its teeth in sharp turns, and repairs meant craning the transmission out through the roof. A watertight engine bay and leaking fuel connectors made the Maybach V-12 prone to fire, and the interleaved road wheels packed with mud that froze solid overnight.

Hitler delayed the 1943 Kursk offensive to wait for the Panther. Of roughly 200 sent, two burned while coming off the trains and only about 40 were running within days, yet those claimed 267 Soviet tanks. Its long KwK 42 75 millimeter gun out-penetrated the Tiger's 88 millimeter, but the sides were only 40 to 50 millimeters thick with 52 rounds stored behind them. In Normandy, Panzer Lehr commander Fritz Bayerlein found it dominant around Caen but too wide and front-heavy for the bocage. The Soviets answered with the 122 millimeter IS-2, the British with the 17-pounder Sherman Firefly, and the U.S. abandoned Lesley McNair's doctrine for the M36 and M26 Pershing. After the war the French 503rd Combat Tank Regiment ran 50 captured Panthers until 1952.

• Changing one damaged inner road wheel could require removing up to five outer wheels.
• The early curved gun mantlet deflected hits down into the thin hull roof until a flattened chin was added.
• During the 1944 Warsaw Uprising, the Home Army used a captured Panther named Magda to help liberate the Gęsiówka camp, freeing nearly 350 prisoners.
• Allied statisticians used gearbox and road wheel serial numbers to estimate 270 Panthers built in February 1944; factory records showed 276.
• Bombing Norway's Knaben mine cut molybdenum supplies, and late-war Panther armor became brittle and prone to spalling.
