The MAKS (Multipurpose aerospace system) (Russian: МАКС (Многоцелевая авиационно-космическая система)) is a Soviet air-launched orbiter reusable launch system project that was proposed in 1988, but cancelled in 1991. The orbiter was supposed to reduce the cost of transporting materials to Earth orbit by a factor of ten. The reusable orbiter and its external expendable fuel tank would have been launched by an Antonov AN-225 airplane, developed by Antonov ASTC (Kyiv, Ukraine). Had it been built, the system would have weighed 275 metric tons (271 long tons; 303 short tons) and been capable of carrying a 7-metric-ton (6.9-long-ton; 7.7-short-ton) payload.
Three variants of the MAKS system were conceived: MAKS-OS, the standard configuration; MAKS-T, with upgraded payload capability; and MAKS-M, a version that included its fuel tank within the envelope of the orbiter.
