HB-127 "QUADRUPLE SCREW"
Two shafts move a battleship. It takes four to move a battlecruiser at the speed its doctrine demands.
Each shaft carried its own turbine room, its own bearing line, its own watch. Damage to one was survivable. The redundancy was not decorative. The power figures crept past one hundred thousand shaft horsepower, the propellers grew in diameter, and the stern of every battlecruiser ended in four wakes instead of two.
For the kind of work that asks more of you than you planned to give. Built with redundancy in mind.
Harborborne. Built to Endure.
