The MAKS spaceplane draft project consisted of 220 volumes, generated by NPO Molniya and 70 sub-contractors and government institutes. Development of MAKS was authorised but cancelled after Perestroika. At the time of the cancellation, mock-ups of both the MAKS orbiter and the external tank had been finished. Since it was expected that MAKS could reduce the cost of transport to earth orbit by a factor of ten, it was hoped in the 1990's that development funding could be found. However this has not happened to date.
