Intelsat 4A1

  1975-091A

---

The first Intelsat IVA satellite became Atlantic Primary soon after launch and on-orbit testing. In 1981 it was replaced by an Intelsat V and moved to the Major Path 2 position. It was moved to a spare position in 1983 and then retired in 1986.

Kosmos 997

 1978-032A

---

The third flight of VA No. 009A/1 was a success; on this mission it was called Kosmos-997 (VA No. 009A/P2, although some reports call it 102P). It landed 50 km from Kosmos-998 at the same time as the other capsule.

Comstar 2

 1976-073A

---

The second AT&T Comstar satellite, Comstar D2 or Comstar 202, was launched a few months after the first. By 1986, after transfer of ownership from Comsat to AT&T, the ten year old satellite was maintaining its longitude but letting its inclination increase under the Comsat maneuver technique. The satellite was retired in 1993.
