Abh mod/Damage Control Station Hub
The Damage Control Station Hub was introduced in 0.5.3RC1 (originally 0.5.1). It was made to complement the Emergency Locker. There are supposed to be multiple sized versions but was considered a cheating part at the time. Their release is being pondered by the author.
When a part which can be repaired is damaged the crew can get a tool kit from the storage to repair the part.
It works like the fire extinguisher and does not need special care. Currently only the warp cores can be repaired.
