Glossary

CODAG:  Combined Diesel And Gas Turbine.  The propulsion fit for a warship.  The ship uses the Diesel as its cruise engine, with the GT's for high speed.  CODAG can use either system, or cross link them for faster speed yet good fuel economy.

COEOG:  Combined Electromagnetic Or Gas Turbine.  The propulsion fit for a warship.  The ship can select either one of these engines, not both together.

COGOG:  Combined Gas Turbine Or Gas Turbine.  The propulsion fit for a warship.  Although confusing, one set of GT's are actually Cruise GT's, optimized for fuel economy over speed.

DD:  Destroyer, General

    H:  Helicopter

    G:  Guided Missile

FF:  Frigate, General

    H:  Helicopter

    G:  Guided Missile

FS:  Corvette

GT:  Gas Turbine.  This is a method of Naval engine which utilizes jet engines to provide power to the shafts.  This is a fuel expensive way to travel, though allows the ship to reach max speed.

K:  Corvette

Shaft:  This is a propeller shaft.  Most warships have two or more, so if one is damaged, the other can still be used.  Many warships can travel on one shaft (for sacrifice in speed and maneuverability) to 'pretend' that they are not a warship.

SONAR Signature:  This value represents the noise level the ship puts out vs. its detectability against both Active and Passive SONAR search.  The value is taken away from the sensor operator's (the enemy) skill.  The higher the number, the more quiet the ship is.
