Salyut 2 was launched April 4, 1973. It was not really a part of the same program as the other Salyutspace stations, instead being the highly classified prototype military space station Almaz. It was given the designation Salyut 2 to conceal its true nature. Despite its successful launch, within two days the as-yet-unmanned Salyut 2 began losing pressure and its flight control failed; the cause of the failure was likely due to shrapnel piercing the station when the discarded Proton rocket upper stage that had placed it in orbit later exploded nearby. On April 11 the station lost four solar panels and all onboard power. Salyut 2 reentered on May 28, 1973. Salyut insignia. ...

Salyut 3 was launched on June 25, 1974.
After Salyut 6 manned operations were discontinued in 1981, a heavy unmanned spacecraft called TKS and developed using hardware left from the canceled Almaz program was docked to the station as a hardware test.
Salyut 1 was abandoned on Oct. 11, 1971, but several successor stations over the next 15 years helped pave the way for Mir.
The second Almaz, under the cover name Salyut 3, was successfully launched on Jun. 26, 1974, and its inaugural crew, Pavel Popovich and Yuri Artyukhin, docked with the station on Jul. 3 for a stay lasting a couple of weeks.
The successful Salyut 4 was deorbited on Feb. 3, 1977, bringing the highest civilian honor, Hero of the Socialist Labor, to the chief designer of the spacecraft, Yuri Semenov, and one of the assembly technicians, V. Morozov (despite official objections that Morozov was not a member of the Communist Party)
