the retrofitted oil driller i was on was run by raytheon (big defense contractor). most of the time there was no one from the navy on board. you had a lot of ex-navy sonarmen hired by raytheon for the program. the concept was "proved" on the smaller ship and then raytheon received the contract to build the behemouth's pictured.
