The Raketenjagdpanzer (RakJPz) Jaguar 1 was a German tank destroyer equipped with anti-tank guided missiles. From 1978 to 1982, 316 obsolete Raketenjagdpanzer 2 units were converted into Jaguar 1s by replacing the SS.11 missile system with a HOT launcher and upgrading the armour. During the period 1993 to 1995, new optics and a thermal imaging system were added.
