Russia's most controversial satellite — and the most closely watched object in the geostationary belt. Luch-5X, also known as Olymp-K 2, has made a series of unexplained close approaches to commercial and government satellites operated by other nations, maneuvering to within a few miles of targets including Intelsat satellites, European military spacecraft, and US government satellites. Russia has not explained the purpose of these maneuvers. Independent analysts assess Olymp-K 2 as a signals intelligence or electronic warfare satellite testing proximity operations capabilities against foreign spacecraft — the most concerning behavior exhibited by any satellite in GEO.
