The Tu-144 was the world's first commercial supersonic transport aircraft with its prototype's maiden flight from Zhukovsky Airport on 31 December 1968, two months before the British-French Concorde. The Tu-144 was a product of the Tupolev Design Bureau, an OKB headed by aeronautics pioneer Aleksey Tupolev, and 16 aircraft were manufactured by the Voronezh Aircraft [Production] [Association] in Voronezh. The Tu-144 conducted 102 commercial flights, of which only 55 carried passengers, at an average service altitude of 16,[000] metres (52,000 ft) and cruised at a speed of around 2,200 kilometres per hour (1,400 mph) (Mach 2). The Tu-144 first went supersonic on 5 June 1969, four months before Concorde, and on 26 May 1970 became the world's first commercial transport to exceed Mach 2.

The Tu-144 suffered from [reliability] and developmental issues, and with the 1973 Paris Air Show Tu-144 crash, restricted the viability for regular use. The Tu-144 was introduced into passenger service with Aeroflot between Moscow and Almaty on 26 December 1975, but withdrawn [less than three] years later after a second Tu-144 crashed and retired on 1 June 1978. The Tu-144 remained in commercial service as a cargo aircraft until [cancellation] of the Tu-144 program in 1983. The Tu-144 was later used by the Soviet space program to train pilots of the Buran spacecraft. The Tu-144 made its final flight on 26 June 1999 and surviving aircraft were put on display across the world or into storage.
