A projectile release mechanism is disclosed for facilitating launching of a jet-propelled projectile in the form of a spherical spin-stabilized missile. The apparatus includes a projectile support means which includes a rotary portion having a register section for receiving a unitary nozzle member which is fixed to the missile, for securing the missile to the support means. A fusible joint is formed integral with the unitary nozzle member and is disposed for heating by high-temperature exhaust gas expelled by the missile to release the missile from the rotary portion of the support means. The fusible joint comprises a peripheral ring portion of the unitary nozzle member, which is of a reduced sectional thickness. A plurality of passages are formed through the reduced ring portion for conducting the exhaust gas through the fusible joint. The rotary register section and the unitary nozzle member received therein have complementarily engageable, axially spaced concentric surfaces forming annular flat lands to insure proper alignment of the missile with the spin axis during initial separation of the unitary nozzle member at the fusible joint.
