Strike Cruiser MK I (1976), 1/3000

As the stirke cruiser proposal iterated, it eventually ended up with a 200+ meter long cruiser not unlike an arsenal ship. The proposal planned to modify the USS Long Beach as the prototype and new ships to be built with similar armament/sensor configurations.

However the resultant cruiser, being bigger than even the Long Beach, would have been very expensive, and thus the proposal was discarded.
