 The heritage from the Almaz program is present even today.While the last space station from the Almaz programme was flown as Salyut 5 in 1976, the development of the Almaz TKS spacecraft evolved into the Functional Cargo Block, which formed the basis for several "Mir" modules, the experimental Polyus orbital weapons platform and the "Zarya" module of the ISS.DOS-7 continued to be developed during Salyut 7, becoming the Mir Core Module of the "Mir" space station – the first modular space station, with crewed operations lasting from 1986 to 2000.
