The BAC One-Eleven (BAC-111, BAC 1-11) is a retired early jet airliner produced by the British Aircraft Corporation (BAC). Originally conceived by Hunting Aircraft as a 30-seat jet, before its merger into BAC in 1960, it was launched as an 80-seat airliner with a British United Airways (BUA) order on 9 May 1961.

Feb 24, 2025 · The aircraft was powered by two Rolls-Royce Spey 506 turbofan engines, which gave it a range of 1,500 nautical miles and a maximum cruising speed of 515 mph. The BAC 1-11 Series 200 had a seating capacity of up to 119 passengers, depending on the configuration. BAC 1-11 Series 300: The BAC 1-11 Series 300 was an upgraded version of the Series 200.

The engine employed in this version would have been the Rolls-Royce RB163-67B, later named Spey Mk.606 with a sea level static thrust of 16,900 lbs. This was a development of the Spey 512 and was mounted in a similar way to that of the original Spey engine.

The engine on the BAC1-11 was the Rolls Royce (RR) Spey engine and Rolls had developed a modern engine, the Tay, which powered the new Gulfstream aircraft and a higher thrust version of the Tay had been developed for the Fokker 100 which was about the same size as the BAC1-11.

The BAC One-Eleven (1-11) is a twin-engined regional airliner with a capacity of maximum 119 passengers produced by the British manufacturer BAC, British Aircraft Corporation. The 1-11 was also produced by in small numbers (nine) in Romania as Rombac One-Eleven.

Fitted with more powerful engines (12,550 pounds-force (55.8 kN) Spey 512s); individual customer designations within this series - 86 built. Romanian-built version of the Series 500 - Nine completed. Series 475 with improved aerodynamics and reduced noise - one converted from Series 475. Imperial War Museum, Duxford, Cambridgeshire, United Kingdom.

In 1977, BAC merged with Hawker Siddeley to form British Aerospace (BAE), with "One-Eleven 800" then proposed with a fuselage stretched to 43.28 meters (142 feet), wingspan extended to 31.55 meters (103 feet 6 inches), CFM56 engines, and a passenger capacity of 150 seats in a mixed-class layout.

The last UK built One-Eleven (by this time a British Aerospace product) flew in 1982, by which time production was progressively being transferred to Bucuresti in Romania where nine were built as the Rombac 1-11.
