SRPA Station 003 (SFCA) was a SRPA base located in San Francisco, California. The base served as a coastal military defense station which protected San Francisco and houses long range anti-aircraft gun batteries. The installations of the batteries were upgraded as a direct response to two Chimeran airships that were sighted off of San Francisco within gun range on August 9th, 1952. SRPA 3 also served a research facility which is usually observed and worked by Dr. Fyodor Malikov, and possessing a moon pool, possibly used for testing water-based experiments such as weapons and vehicles.
