Kosmos 1186

 1980-047A

---

Kosmos-1186 was launched in Jun 1980. One fragment cataloged near the launch time may be rocket debris; the first pair of satellites seems to have been deployed a month later. Notable was object 1980-47T, one of nine objects released on about 1981 May 25, almost a year after launch. It had a reported radar cross section of almost 20m, and may have been a special radar reflection target. Its low drag compared to other objects released at the same time may indicate a larger mass. Another of the May 1981 objects, 1980-47X, had similar low drag but no large radar return; it may have been a comparison test mass; its decay date may be in error.
