A vehicle or craft is provided for propeller propulsion with start assist by a releasable rocket engine. The craft is launched from a silo of square-shaped cross-section containing the starter motor for the propeller, whose engine is started while the craft is still in the silo. Diagonally opposed corners of the silo are provided with rails, in which run guides on rudder fins of the craft. The wings are pivoted to the fuselage for deployment whereby the wing tips do not move forward. The rocket engine is jettisoned shortly after take-off by simple disengagement. Parts of the wings and/or the rear of the fuselage may be jettisoned shortly before the craft reaches the target area.

An unmanned aircraft to be launched from a silo having two parallel running, diametrically opposed rails, comprising: a fuselage; a pair of fins with rudders extending oppositely from the fuselage and having guide means for running in the rail means; wing means, deployably attached to the fuselage and prior to launch being retracted towards the fuselage into a position in which the respective wing tips are not more rearward in relation to the fuselage than in a deployed position; the fuselage containing an engine, there being a propeller for being driven by the engine, the propeller having dimensions to inscribe a circle upon rotation whose diameter multiplied by the square root of two is less than a total extension of the fins; and rocket engine means releasably connected to the fuselage aft of the propeller.
