The Znamya 2.5 was a successor to the Znamya 2, which was deployed on 5 February 1999. It had a diameter of 25 m, and was expected to produce a bright spot 7 km in diameter, with luminosity between five and ten full moons. However, soon after deployment, the mirror caught on an antenna on the

space station. The mirror deployed successfully, and, when illuminated, produced a 5 km wide bright spot, which traversed Europe from southern France to western Russia at a speed of 8 km/s. The bright spot had a

The Znamya 3 was intended to be a scaled-up version of the previous two
Znamyas, with a diameter of 60–70 metres. It was never built, as the project was abandoned after the failure of the Znamya 2.5.
