-R-

Range -- -- Distance to a contact.

Reactor Compartment -- -- Compartment housing the reactor, pressurizer, steam generators, and reactor main coolant pumps. Access for and aft is through a shielded tunnel, since anyone inside the compartment when the reactor is critical would be dead within a minute from the intense radiation.

Reactor Main Coolant Pumps -- -- Also called reactor recirc pumps. Large pumps (500 horsepower each) that force main coolant water through the reactor and then to the steam generators. There are three in each of the two loops. Special design allows for zero leakage.

Reactor Plant Control Panel (RPCP) -- -- Control panel in the maneuvering room where the reactor operator controls the reactor.

Reduction Gear -- -- The mechanism that converts the high RPM of the two main engines to the slow RPM of the screw. Solves the problem of how to let the main engines rotate at their most efficient high speed and the screw at its most efficient low speed. Creates the problem of radiated noise. Reduction gears are being replaced by electrical drive, in which the main engines will drive generators that will power a main motor.

REM -- -- Roentgen Equivalent Man. A unit of radiation dosage that takes into account tissue damage due to neutron radiation. Convenient since it allows gamma, alpha and neutron radiation to be measured with the same units. 1000 rem will kill half the population exposed to the radiation. Yearly dose for submarine personnel is restricted to less than 25 millirem.

Rig for Black -- -- Submarine term meaning “turn off the lights.”

Rig for Dive -- -- A detailed valve and switch lineup done in preparation to dive. Initially done by a dolphin-wearing enlisted man and checked by a dolphin-wearing officer.

Rig for Patrol Quiet -- -- Ship systems lineup to maximize ship quieting while allowing normal evolutions such as cooking, equipment maintenance, cleaning and exercise.

Rig for Ultraquiet -- -- Ship systems lineup done in a tactical situation such as trailing or wartime patrol. The quietest equipment is operating and cooking, showering, laundry and movies are curtailed.

Rig for White -- -- Means “turn on the lights.”

RO (Reactor Operator) -- -- Nuclear-trained enlisted man who mans the Reactor Plant Control Panel and reports to the EOOW.

RPG -- -- Rocket-propelled grenade or rocket-propelled depth charge. Used by a skimmer and constitutes cheating.

Run -- -- An at-sea period, such as an op. Example: northern run (deployment to the Barents Sea in the close vicinity of our Russian friends), NATO run (playing with friendly ships of our allies), Med run (a trip to the Mediterranean), WestPac run (trip to the western Pacific, usually to the close vicinity of our Russian friends), etc.

Run-to-Enable -- -- Initial torpedo run taking it away from own ship. During the run-to-enable, the warhead is not armed and the sonar is shutdown. After run-to-enable, the weapon activates the sonar system (either active or passive depending on the selection) and executes it search pattern.
