Unholy Posted August 3, 2004 Report Share Posted August 3, 2004 In un altro post abbiamo parlato di possibilità di utilizzare un sistema di guida basato tanto su radar attivo quanto IR: ciò è già stato fatto in passato: AIM-47A FALCON! John ne ha parlato in un altro post... Eccovi qua: Cancelled 1965 for YF-12. Semi-active / active-radarguided active-radarguided. Total Mass: 360 kg. Core Diameter: 0.34 m. Total Length: 3.20 m. Span: 0.85 m. Maximum range: 185 km. Boost Propulsion: Solid rocket. Guidance: Semi-Active Radar + Infrared Homing. Maximum speed: 6,770 kph. Historical Essay © Andreas Parsch Hughes GAR-9/AIM-47 Falcon In 1958, Hughes started to develop the AN/ASG-18 fire-control system (FCS) for the forthcoming North American F-108 Rapier long-range Mach 3+ interceptor. The missile component of the system was to be a large derivative of the AIM-4 Falcon missile family, designated GAR-9, which was to have a range of more than 160 km (100 miles). The large radar of the AN/ASG-18 was to provide target illumination for the semi-active radar mid-course guidance. For terminal homing, the GAR-9 was equipped with an infrared seeker. The GAR-9 was powered by a storable liquid-fuel rocket motor, and for some time, a low-yield nuclear W-42 warhead was envisioned, but eventually a conventional HE warhead was used. When the F-108 was cancelled in 1959, the USAF looked for a replacement and found the Lockheed A-12 "Blackbird" reconnaissance plane. It was decided to developed an interceptor derivative, designated YF-12A, which would use the AN/ASG-18 FCS and the GAR-9 missile. In 1963 the XGAR-9 prototype missile was redesignated XAIM-47A, and in the same year, flight tests of the YF-12A and the XAIM-47A began. During the test program, several successful long-range intercepts of target drones were performed. In 1966 the planned F-12B production interceptor was cancelled, which also meant the cancellation of the AIM-47A production missile. About 80 XAIM-47A's had been built, and some of the technology was used by Hughes to develop the AIM-54 Phoenix long-range air-to-air missile for the U.S. Navy. An air-to-ground derivative of the AIM-47 was briefly evaluated as the XAGM-76A. Specifications Note: Data given by several sources show slight variations. Figures given below may therefore be inaccurate! Data for XAIM-47A: Length 3.20 m (126 in) Wingspan 0.838 m (33 in) Diameter 0.335 m (13.2 in) Weight 363 kg (800 lb) Speed Mach 6 Range 210 km (130 miles) Propulsion Lockheed storable liquid-fuel rocket Warhead High-explosive Main Sources  Bill Gunston: "The Illustrated Encyclopedia of Rockets and Missiles", Salamander Books Ltd, 1979  Paul F.
