Description
The “Lark" is launched from a ship board catapult for attacking high-altitude bombers. It has cruciform wings and tail surfaces, the tail surfaces being offset 45° from the wings, and is powered by two liquid-fuel rocket motors, one continuous and one intermittent. It is radio controlled in the first part of its flight, its position determined by the launching ship’s radar. When it comes within radar homing range of the target, the homing mechanism takes control.
It is launched at 150 mph from a multiple charge shipboard catapult by means of two 12AS1000 F JATO units which are jettisoned after exhaustion.
Two acid-aniline liquid rocket motors furnish the propulsion. One 200 pound thrust continuous rocket is augmented by a 400 pound thrust intermittent motor. The latter is governed by a Mach Number meter so that a more or less constant speed is maintained. Both rockets total about 75 pounds weight and have a supply of 490 pounds of fuel. The two 12AS1000 F JATO units are used to assist launching and are jettisoned after exhaustion.
