Jagdpanther had a cannon that was previously used on the German heavy tank used during what event?
Jagdpanther The Jagdpanther (German: "hunting panther"), SdKfz 173, was a tank destroyer built by Nazi Germany during World War II based on the chassis of the Panther tank. It entered service in 1944 during the later stages of the war on the Eastern and Western Fronts. The "Jagdpanther" combined the 8.8 cm KwK 43 cannon of the Tiger II and the armor and suspension of the Panther chassis, although it suffered from the general poor state of German ordnance production, maintenance and training in the later part of the war, which resulted in small production numbers, shortage of spare parts and poor crew readiness.
Raketenjagdpanzer 1 The Raketenjagdpanzer 1 is an anti-tank guided missile-armed tank destroyer (the first such vehicle in service with the West German Armed Forces) that entered service in 1961. It was built on the chassis of the Hispano-Suiza HS-30, which was also used on the Schützenpanzer SPz 12-3, and armed with twin French SS.11 antitank guided missile launchers. Only one of the missile launchers is visible from the outside at any time, however, as the other is retracted into the hull to be reloaded when the first is ready to fire.
