A mechanism for releasably holding and pre-heating a model, prior to launch of the model by and from a gun. The model is initially held in a collar of the mechanism in the breech of the gun, and is pre-heated by an induction coil and an r-f current. The coil is then removed, and the model and the collar are propelled forward through the breech by pressurized hydrogen gas, with the breech being closed and with the heated model being inserted into the launch tube (i.e., the "barrel") the gun. The gun is then fired, and the heated model is launched, without any significant cooling of the model. Some advantages of this mechanism are a quick "heat-and-fire" cycle, and the simplicity in structure and in operation of the mechanism.
