The Sub Weapons Research is a Upgrade Building that is needed to unlock upgrades for the Monkey Sub. It costs City cash700 to build, takes about 6 hours (?) to build, will give 20XP once construction is completed.

Special Buildings are needed for the last upgrades on both paths. First Strike Capability requires the Super-Bomb Research Centre, while the Bloontonium Reactor requires the Submarine Core Reactor building.
