Cyclops Depth Module MK1
The Hull Reinforcement is an upgrade for the Cyclops.
It can be constructed using the Builder. However, it does not function yet.

Speculation
A screenshot by the developers seems to imply that adding this upgrade to the Cyclops will increase its crush depth from 200 to 1200 meters and its safe depth from 100 to 450 meters. However, in a Trello entry by the developers, an increase of the crush depth by 100 meters per Hull Reinforcement upgrade installed. It may also be just a temporary upgrade that might get removed in later builds.
