1983-016A
Ekran No. 18L, also known as Ekran 10, was launched on 1983 Mar 12 by Proton from Baikonur. The spacecraft had been held in storage for several years owing to launch scheduling issues, but once on orbit it functioned for more than a year before its replacement. It was being utilized as an orbital spare as late as 1990.
