An integral missile antenna-fuselage assembly (50) is provided for integration into an armament missile (12) which carries primary missile loads, houses internal electronic assemblies, provides mounting surface zones for external sensor antennas (71) , and protects sensitive antenna components from supersonic aerodynamic heating. Each end of the fuselage assembly (50) is formed from a fastener ring (52,54) having a circumferential recess (84,86) which receives a filament wound main structure (60) to form the missile fuselage tube. Preferably, a titanium liner (58) is first joined to each fastener ring with a step-lap joint (94,96) along which it is adhesively bonded. The liner (58) and adjacent fastener ring portions (52,57) provide a mandrel on which a graphite/Bismaleimide (BMI) resin pre-preg is filament wound and co-cured to form the integral fuselage (60). A plurality of Graphite/BMI doublers (62,63,64,65) are axisymmetrically positioned on the fuselage external surface to form four antenna cavities (66,67,68,69) which receive antennas (71) therein. Subsequently, antenna spacers (72,73,74,75) encase the antennas (71) about which a radome overwrap (70) is filament wound with a Quartz/BMI pre-preg. The entire structure (70) is then integrally cured to the internal fuselage (60) and antenna spacers (72,73,74,75) afterwhich it is surface treated (76) and overcoated (78).

An assembly for use in an armament missile constructed from a plurality of joined-together sections, said assembly comprising: a missile fuselage tube constructed of a composite material having reinforcing fibers impregnated with resin; a fastener ring having an outer rim portion with a radially inward extending circumferential recess formed therein for receiving at least ends of the fibers; circumferential means surrounding the ends of the fibers to secure the ends of the fibers within said rim portion recess; and said resin further impregnating the ends of the fibers and the circumferential means to bond the tube to the ring.
