Yes, but those same naval engineers very often need to adapt non-military (what today we call COTS) equipment for duty on a ship. They know how to deal with modifying equipment to get to their standard. When "washing machine" disk drives were used on ships, they would have gigantic shockmounts installed. Certainly the Fastrand - and the rest of the Univac associated with it - would get this treatment. About half the time I hear the Fastrand story, it involves the Fastrand's gyro effects interfering with the ships movement. This I find completely implausible. -- Will > and the propulsion system has far greater > forces to deal with than gyroscopic effects.
