Russia launched 15-year old ocean surveillance satellite

Last June Russia launched a 15-year old US-PU Legend (or Legenda) ocean
surveillance satellite, which failed to activate one of its two solar
batteries. The Legend is to be replaced by the new Liana system.

Could this mean all the Russian ocean surveillance satellites currently
in the orbit are as old as this Cosmos 2421?

Spying Satellite Fails Mission

Launched to orbit June 25, the Legend satellite of offshore electronic
reconnaissance has failed so far to get down to performing the tasks.
Of two solar batteries, one didn't open and the satellite lacks power
to activate devices of surveillance and target indication.

It was the U.S. Space Command that first reported problems of Russia's
US-PU satellite. Though the RF Defense Ministry, Russia's Space Agency
(Roskosmos) and Space Forces declined to comment, a source with the
General Naval Staff said Saturday that Cosmos-2421 [US-PU got this name
after delivery into the orbit] really has problems, which are currently
tackled by experts.

The satellite spent past week in maneuvers, attempting to open the
second battery. All efforts proved fruitless, the source said, but
Arsenal Design Bureau that developed the satellite still hopes to
remove trouble.

But the military don't share optimism of producers, the more so that
the satellite was made 15 years ago and kept in the stockpile till the
launch. Besides, Arsenal has troubles not only with US-PU but also with
a new Liana, which is expected to replace Legend.
