A venting lifting plug is provided for an unfuzed munition having a cavity with internal threads.

Venting lifting plug for munitions

A fragmentation pattern is formed on a surface of a warhead using an etchant process. An etchant resistance material is coated on an interior surface of the warhead casing. A portion of the etchant resistant material is selectively removed by a directed energy process and an etchant is applied to the exposed portion of the warhead casing surface thereby etching the fragmentation pattern. Alternatively, a protective coating is applied over the entire surface thereby creating the fragmentation pattern.

Lithographic fragmentation technology

A fragmentation pattern is formed on a surface of a warhead using a lithographic process. A photoresistant material is coated on an interior surface of the warhead casing. A portion of the photoresistant material is selectively cured by projecting an image of the fragmentation pattern onto the photoresistant material. The uncured portion of the photoresistant material is removed and an etchant is applied to the exposed portion of the warhead casing surface thereby etching the fragmentation pattern. Alternatively, a protective coating is applied over the entire surface thereby creating the fragmentation pattern.

A statically stabilized projectile may include a fixed tail boom that may be disposed in the through-bore of a sliding tail boom. The sliding tail boom may translate or extend rearward with respect to the fixed tail boom before the projectile exits a launch tube. The through-bore of the sliding tail boom may include a tapered portion. A tail boom sleeve may be fixed to a rear portion of the fixed tail boom. The tail boom sleeve may include a tapered portion that abuts the tapered portion of the through-bore when the sliding tail boom is in an extended position.

Extendable stabilizer for projectile

A venting lifting plug is provided for an unfuzed munition having a fuze cavity with internal threads, the venting lifting plug is formed of a threaded ring having both internal and external threads together with a lifting plug having a lifting ring, a neck and a round portion having external threads, external threads on the threaded ring being in threaded engagement with internal threads on the fuze cavity of the munition, internal threads on the threaded ring being in threaded engagement with external threads on the lifting plug, and a threaded joint formed between the lifting plug and threaded ring is soldered together with one or more eutectic materials having a melting point lower than a predetermined critical temperature of cook-off gases from the munition.
