to detonate the HEAT warhead. The HOT 1 and HOT 2 use the warhead fuzing system previously described. The latest version of the HOT family, the HOT 3, uses tandem charge feature to defeat tanks fitted with explosive reactive armor. A laser-proximity fuze located in the front half of the nose measures the distance between the target and the missile. At the correct range, the small nipple on the front nose containing a small HEAT warhead is ejected forward from the missile body to pre-detonate the reactive armor followed by the detonation of main HEAT warhead. Performance relative to comparable weapons Launch platforms HOT missiles have been deployed on both vehicles and helicopters. The Bundeswehr upgraded the Raketenjagdpanzer 2 tank destroyer to use the HOT missile in what was designated as the Jaguar 1. The Jaguar 1 mounted a single Euromissile K3S launcher and carried 20 HOT missiles, one of which was carried in the launcher. This tank destroyer was also used by Austria. France developed a variant of the AMX-10P that substituted an armored four-tube HOT missile launcher called the Lancelot for the vehicle's regular 20mm cannon turret. The Lancelot turret carriers 20 HOT missiles—4 mounted and 16 stored inside—and uses a sight with X12 magnification as well as a laser rangefinder. The only known customer is Saudi Arabia. HOT missiles have also been mounted on wheeled vehicles such as the Panhard VCR/TH and the VAB VCAC with the Mephisto turret. Both the VCR and the VCAC carried four ready-to-launch missiles. The main advantage that the VAB Mephisto turret has over the TH turret is that both the operator and the missiles are both under armor and the Mephisto turret can be retracted flush with the vehicle's top for loading on either the C-130 or C-160 transport aircraft. In an unusual move, in 1986 Euromissile offered a single-round ground-launched system for HOT missiles called ATLAS (Affut de Tir Leger Au Sol - which approximately translates as light ground-firing mount) for installation on smaller unarmored vehicles, like the Jeep or Land Rover. The object was to field an antitank weapon that long-range patrols could use to engage heavy armor beyond the range of the tank's main cannon. The ATLAS is similar to the TOW mounted on various four-wheel-drive light vehicles. But, unlike the TOW light vehicle mount, there is a shield to protect the gunner against the HOT's booster and
