|1MC - The basic
one-way communications system on a vessel. Reaches all spaces on a ship.
Used for general announcements, and to transmit general alarm system
signals. Control stations are located on the bridge, quarterdeck, and
central station. Other transmitters may be installed at additional
points. There are other MC and JV circuits used for communications
within the ship. They are typically system-specific, i.e. weapons
systems, navigation communication, engineering systems, firefighting,
130-rpm fish - A form of sea life (type unknown) which makes a sound very similar to a propeller turning at 130 rpm.
90-Day Wonder – Derisive term for a graduate of OCS. The derision arises from the lack of experience and naval knowledge of the typical graduate. Commonly seen as "90-Day Blunder."
99 – (USN aviation) Precedes a radio call which applies to a group of aircraft, e.g. "99 Guntrains" would address all aircraft with a Guntrain callsign.
Aback – Backing a sail is turning it so that the wind hits the front face; the effect is to slow a ship or boat. A sail which is being backed is said to be ‘aback.’ A sailing ship which accidentally goes aback when tacking loses its momentum and is said to be ‘in irons.’ A person is said to be ‘all aback’ when he is confused or surprised.
Abaft – Aft of a given point on a ship; e.g. the bridge is abaft the bow.
ABC – Atomic, Biological, Chemical. An early term since supplanted by NBC.

Acey-Deucey Club – A club for E-5 and E-6 enlisteds (Second- and First-Class Petty Officers).
ACM - Air Combat Maneuvering. Dogfighting practice.
Acockbill – Out of alignment or awry. In original usage, if a sailing ship’s yards were not all aligned, she was said to be "all acockbill." See also SQUARED AWAY.
Active Homing – A homing (guidance) method where the missile provides its own signal (typically either radar or sonar) transmissions and homes in on the energy reflected off the target.
Adrift – (1) Not secured; scattered about; not properly stowed, or out of place. (2) (RCN) Missing in action. "Oh no, I'm adrift for the meeting and the Bossman'll be there!"
Advance and Transfer – Two separate terms involving a ship’s turn. Advance is the forward progress made between the time that the rudder is put over and the time the ship is steady on her new course. Transfer is the horizontal displacement of the ship during the same period of time. Advance is maximized in a turn of 90 degrees or more; transfer is maximized in a turn of 180 degrees or more.
