The Bristol Type 223 represented an early British initiative in the development of a supersonic transport. During the late 1950s and early 1960s, the Bristol Aeroplane Company pursued multiple designs as part of a government-supported collaboration between companies. This effort culminated in the Type 223, envisioned as a transatlantic airliner capable of carrying approximately 100 passengers at around Mach 2. Simultaneously, the French manufacturer Sud Aviation was advancing a comparable project, the Super-Caravelle. These parallel developments converged in November 1962, resulting in the joint initiative known as the Concorde program.
Background
By the mid-1950s, British aerospace had progressed to producing supersonic test aircraft and had identified wing configurations suitable for continuous supersonic flight: notably, the sharply swept M-wing and the slender delta wing. Although speeds approaching Mach 3 were theoretically achievable, practical engineering limitations restricted operational velocity to about Mach 2.2. This constraint was largely due to material challenges, especially the softening of duralumin at elevated temperatures. While stainless steel was considered as an alternative, it presented significant cost and manufacturing difficulties, exemplified by experience with the Bristol 188.
STAC
Established in 1956, the Supersonic Transport Aircraft Committee (STAC), chaired by Sir Morien Morgan, was tasked with investigating supersonic transport possibilities. Its 1959 findings proposed two configurations: an M-wing design for a Mach 1.2 medium-range airliner and a straight-wing model capable of Mach 1.8 powered by six engines mounted at the wingtips. Further analysis favored a gothic delta wing form, leading to design contracts awarded to both Hawker Siddeley and Bristol towards the end of 1959. These studies explored aircraft structures using aluminium alloys for Mach 2.2 speeds and stainless steel for Mach 2.7 performance.[1] The Bristol Mach 2.7 concept, designated Type 213, was shaped by lessons from the Bristol 188 project; chief designer Archibald Russell advocated for a lower-speed approach using aluminium alloys.[2]
The thin-winged Type 213 gained STAC's preference, resulting in a 1961 contract for comprehensive design studies of a six-engine, Mach 2.2 aircraft seating around 130 passengers under the Type 198 label. Due to escalating expenses, STAC mandated that Bristol seek international collaboration. In that same year, Sud Aviation introduced the smaller Super-Caravelle at the Paris Air Show. Bristol responded with an intermediate proposal—the Type 223—positioned between Sud’s Super Caravelle and Bristol’s Type 198 designs. Both companies pursued a cooperative development effort, negotiating government-supported consortium agreements throughout 1962 with projected development budgets ranging from £15 million to £170 million.[1] The Concorde project was officially initiated on 29 November 1962 when UK Aviation Minister Julian Amery and French ambassador Geoffrey de Courcel formalized their agreement.[3]
