Abstract: An aircraft is set forth having a fuselage (22) which terminates at a forward bulkhead (38). Secured to the fuselage (22) to complete the aerodynamic shape of the aircraft is one or a number of interchangeable, mission specific nose modules (46). A plurality of sleeves (66) is disposed on the fuselage (22) at the forward bulkhead (38) and a like number of corresponding pins (106) are positioned at the nose module (46), reception of the pins (106) into the sleeves (66) as the nose module (46) is mated to the fuselage (22) providing for first gross positional alignment and, as the pins (106) approach full insertion into the sleeves (66), fine positional alignment for interconnection. Couplers (68, 70) are included to provide connection between any electronics in the nose module (46) and monitoring/control electronics disposed on the fuselage (22) and its cockpit (26). The couplers can accommodate six degrees of malalignment to receive the other fixed portion of the coupling for interconnection thereof.
