The submarine pen was Yuri's ship construction and maintenance facility during the second iteration of the Third World War. Despite the name shown in the cameo, it was also capable of creating conventional ships (if appropriate technology was stolen) and amphibious transports. Due to consistency issues during development, this building's tooltip refers to it as Yuri naval yard.
The submarine pen can produce the following ships:
|Hover transport||none||Transport (12 slots)|
|Boomer||Psychic radar||Submerged when not attacking ground targets or damaged|
Immunity to giant squids
Detecting submerged units
- Yuri's Revenge patch 1.001: all naval shipyards can now assign rally points during the buildup animation.
