Orbital nuclear warhead platform

An orbital nuclear warhead platform was a device used during Earth's Cold War in the late 1960s. The United States of America launched such a platform in 1968 as a counter to a launch of a similar device by other major political entities. 

While the American platform was launched from McKinley Rocket Base, sabotage by newly-arrived agent Gary Seven resulted in the platform's detonation in orbit.

The platform was codenamed Prometheus One and its superstructure was based on the United States Air Force’s Manned Orbiting Laboratory (MOL) project.
