Svetlanas

Svetlanas is a term that can refer to several entities, most notably a series of Soviet and Russian orbital-based nuclear-weapon detonation detection satellites. These satellites were part of the Oko (meaning "eye") program, designed to detect launches of intercontinental ballistic missiles by observing the flashes of light from missile engine exhaust. The primary goal of the Oko system was to provide early warning of a nuclear attack. Several satellites under the "Svetlana" designation were launched as part of this program.

The name "Svetlana" also appears as a common given name for women in Slavic countries, particularly Russia. It is derived from the Old Church Slavonic word "svetlu," meaning "light" or "bright." As a given name, Svetlana has a long history and is widely used.

Additionally, "Svetlana" can occasionally be used informally as a nickname or term of endearment, though this usage is less common and context-dependent. The primary technical and historical significance of "Svetlanas" lies within the context of the Oko satellite program.
