By the Numbers

Every Navy ship that moves does so because of MMs. Gas turbine plants in destroyers produce 80,000 horsepower — and the E-4 maintaining them earns $32K a year while marine engineering contractors charge $150/hour for the same work.

Non-nuclear MMs maintain the steam, gas turbine, and diesel propulsion plants of surface ships. A Nimitz-class carrier's conventional auxiliary systems — maintained by MMs — include enough piping to stretch 1,200 miles if laid end-to-end.
