— — Copyright: This glossary was created and has been maintained by Jeff Crowell since 1990. Corrections, comments, or suggestions for improvement will be welcomed. This information may not be reproduced or otherwise displayed without the express consent of the author. All rights reserved.
— — Notes: Unless otherwise noted, all terms are common to the USN, USMC, USCG, USMS, or NOAA. The abbreviation RN denotes Royal Navy usage. Similarly, RCN = Royal Canadian Navy, RAN = Royal Australian Navy, RM = Royal Marines, RNZN = Royal New Zealand Navy, UK = general usage in militaries of the former British Empire.
— — Listing: Terms in ALL-CAPS have a separate listing (same as q.v.).
— — Pronunciation: A great deal of variation in pronunciation may be experienced between services or between countries. For example, in the US Navy and Marine Corps ASAP is spoken as a word: eh' sap (eh = long a sound) while the US Army and US Air Force essentially spell the word aloud, speaking each letter: eh ess eh pee (again, eh is pronounced as the long a sound).
— — Appendices: The following appendices supplement this glossary: Appendix A: Aircraft Nicknames; Appendix B: Dolphin Codes; Appendix C: Falcon Codes; Appendix D: Weights and Measures; Appendix E: Jersey Colors; Appendix F: Flight Deck; Appendix G: Signal Flags; Appendix H: Anchor Parts; with these and other Editorial Notes.
— — Special Note: Since days of yore the military in general, and sailors in particular, have often had a rather pithy (dare I say tasteless?) manner of speech. That may be changing somewhat in these politically correct times, but to Bowdlerize the sailor's language represented here would be to deny its rich history. The traditions and origins remain. While I have attempted to present things with a bit of humor, if you are easily offended, this glossary may not be for you. You have been warned!

# : Numbers

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, etc.
13-Button Fly :: The fly (front closure) of the CRACKERJACK UNIFORM trousers.
27 Charlie :: A program of modification to, especially, Essex class aircraft carriers, or a carrier which has had the modifications done. Modifications included the addition of a HURRICANE BOW and ANGLED DECK.
3-9 Line :: A.K.A. wingline. The virtual line running between 3 o'clock (starboard beam) and 9 o'clock (port beam) of an aircraft.
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 also seen as '90-Day Blunder'.
99 :: (USN aviation) Radio PROCEDURE WORD, precedes a radio call which applies to a group of aircraft, e.g. "99 Guntrains" would address all aircraft with a Guntrain callsign.
130-rpm fish :: A form of sea life (type unknown) which makes a sound very similar to a propeller turning at 130 rpm.

A : ALFA

AAW :: Anti-Air Warfare.
AAWC :: Anti-Air Warfare Commander.
Aback :: Backing a sail is turning it so that the wind hits the forward 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.
Abbajabba :: The all-attitude indicator on some tactical aircraft, particularly the A-4; provides attitude data in roll, pitch, and yaw. Comes from the AJB-3 designation for the device.
ABC :: Atomic, Biological, Chemical. An early term, since supplanted by 'NBC'.
Accelerated Stall :: (Aviation) A stall which occurs during accelerated flight, i.e. while the pilot is pulling G's. Generally, a much more violent event than a stall occurring during level (unaccelerated) flight.
Acey-Deucey :: Backgammon, a board game traditionally played in off-duty hours.
Acey-Deucey Club :: A club for E-5 and E-6 enlisteds (Second- and First-Class Petty Officers USN).
ACLS :: Automatic Carrier Landing System. An autopilot-coupled system capable of bringing the aircraft aboard without pilot input.
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.' Contrast with SQUARED AWAY.
Action :: Directive to initiate a briefed tactical sequence or maneuver, such as a turn at the initial point.
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.
Admiral's Doorbell :: The emergency jettison button on an aircraft; use it, and you'll be explaining to The Man.
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. Contrast with FINAL DIAMETER.
AEF/A :: (USN submarine) Auxiliary Electrician Forward/Aft.
A.F.R.T.S. :: Spoken as 'a-farts', with long first 'A' sound; Armed Forces Radio and Television System, a US system providing television and radio entertainment to forces overseas. Recently, the preferred interpretation has become 'American Forces Radio and Television Services.'
AFFF :: A.K.A. Light Water. Aqueous Film Forming Foam. A fire-fighting agent which is mixed with water and sprayed on flammable liquids fires. Spoken "A triple-F". for the foam's ability to float on oil or gasoline. Replaced protein foam. Unlike blood-based protein foam, AFFF is self-healing, in that holes in the foam blanket will close by themselves, preventing REFLASH.
Afterburner :: (1) (Aviation) A system in the engine(s) of many tactical aircraft (and a very few non-tactical a/c such as the SR-71 and U-2) which dramatically increases thrust at the cost of doubling (or more) the fuel consumption. Analogous term in UK-based countries is 'reheat.' (2) A flaming shot (i.e. a shotglass of liquor which has been ignited) which, after being consumed, still has fire in the glass.
A-gang :: Auxiliaries Division of the Engineering Department. These personnel operate and maintain the ship's auxiliary equipment (air conditioning systems, distilling units, air compressors, etc.)
A-ganger :: Auxiliaryman. Member of A-gang.
A-gear :: See ARRESTING GEAR.
AGI :: A.K.A. Tattletale. Ship designation for Auxiliary, Intelligence Gathering. Refers to USSR 'trawlers' (or, more often, purpose-built ships) formerly stationed off NATO ports and following major fleet units. The AGI's mission is both intelligence-gathering and providing location (and therefore, potentially, targeting) data for key targets such as aircraft carriers.
AGL :: (Aviation) Above Ground Level. A method of defining an altitude with respect to local ground elevations. The altitude that really matters for safety of flight. Contrast with MSL.
(Air) Boss :: The watchstander responsible for the safe operation of the carrier's flight deck. His minions direct the placement of aircraft on the deck, monitor the operation of catapults and arresting gear, and direct firefighting efforts if a crash occurs. Contrast with LITTLE BOSS.
Airdale, Airedale :: A.K.A. BROWNSHOE. Naval aviator. Can also refer to any member of the aviation community, officer or enlisted. From envy, often modified by non-aviation types with the adjective "fucking".
Air Start :: (1) The process by which a flamed-out jet aircraft engine may be restarted in flight. (2) The process of starting a large Diesel engine using air to turn the engine over. (3) Blowjob.
Air Wing :: The officers and men assigned to the aircraft aboard a ship, whether a carrier (usually referred to as a 'carrier airwing') or a smaller vessel (generally referred to as an 'air det' (detachment)); the airwing has a separate administrative and operational chain of command.
Airy-Fairy :: (1) (RN) Fleet Air Arm personnel. See WAFOO. (2) (RCN) Vague or impractical suggestion.
A.J. Squared-Away :: (1) The mythical sailor who always has his shit together. (2) A mnemonic taught to Data Processing specialists (now combined with Radiomen to form the Information Technician's rate) as a memory aid for recalling the Hollerith code for computer punch cards. The first zone (12) begins with 'A', the second (11) with 'J', the third (10) with 'S.'
Alaskan Fits :: A.K.A. Arctic Fits. What ensues when one attempts to urinate while the thickness of one's clothing exceeds the length of one's wedding tackle (penis).
Aldis :: (UK) A handheld signaling lamp.
Alert Five :: Aircraft on five-minute alert, i.e. which can be airborne within 5 minutes or less of the 'go' signal. This generally requires that the aircrew be seated in the aircraft at all times. There may also be aircraft (and, therefore, aircrews) on Alert Fifteen, etc., in which cases the aircrew may be out of the aircraft but must remain nearby, in the Ready Room, etc.
All Ahead (Flank, Standard, etc.) :: A system of commands for ordering engine, and therefore ship, speeds. In the U.S. Navy, the usual increments of the command are: One Third, Two Thirds, Standard, Full, and Flank. Gas turbine ships, increasingly common in the U.S. Fleet, often break 'Flank' speed into further increments: Flank One, Flank Two, and Flank Three. Engine orders for a multi-screw ship name the engine or engines involved ('all,' 'port,' etc.) and the engine speed increment. So a typical engine order aboard an American gas turbine ship might be 'All engines ahead Flank One for 25 knots.' To minimize the chance of confusion, it is standard practice in the USN to use port/starboard for engine orders, and left/right for helm orders. A typical combined engine/helm order might be "Starboard engine ahead one third, port engine back one third, left full rudder." Maximum permissible BACKING bell is 'Full.'
All Ahead Bendix :: Traditionally, an engine order for 'max tracks,' i.e. as fast as she can go. The ENGINE ORDER TELEGRAPH was traditionally made by the Bendix Company, and was so marked just past the forward end of the annunciator quadrant. Therefore, pushing the E.O.T. annunciator handles as far forward as they would go brought the pointer near the word 'Bendix.' Actual use of the phrase 'All Ahead Bendix' tends to irritate the Chief Engineer.
Allocated :: Engagement status, as: "Track 1234 allocated fighters" (indicates that NTDS track number 1234 will be engaged by fighter aircraft).
Alfa Mike Foxtrot :: Phonetic acronym for "Adios, Motherfucker." Polite form: "Adios, My Friend." Also seen (and spoken) as individual letters, 'AMF.'
Amateur Night :: The day after payday, when nothing seems to go right, especially shipboard evolutions.
Amphib :: Ship whose primary mission involves amphibious landings.
Amp Tramp :: (RCN) Ship's electrician.
Anchor ( ) :: (1) (Aviation) To hold overhead or in the vicinity of a specified location. (2) (Surface Navy) From the process of weighing anchor, the sequence of reports is usually as follows: (Anchor) at short stay -- the ship has been pulled up to the anchor, but the anchor is still lying on the bottom, more or less undisturbed. (Anchor) up and down -- the anchor's flukes have broken free of the bottom, and the shank is more or less vertical. The crown of the anchor is still resting on the bottom. (Anchor) aweigh -- the anchor has left the bottom. Legally, at this point the ship is UNDER WAY, whether or not it is MAKING WAY. Anchor Parts
Anchor-faced :: (RN) Anyone who is enthusiastic about the Navy.
Anchor Clanker :: (1) Boatswain's Mate. (2) (RN) Ordinary seaman. See DECK APE. (3) Sailor.
Anchor Pool :: The betting pool on the actual (versus planned) hour and minute the ship will drop anchor or tie up.
Andrew (the) :: (UK) Nickname for the Royal Navy. Refers to pressgang leader Andrew Miller who, it was said, owned the Royal Navy.
Angled Deck :: A.K.A. Angle Deck, The Angle. The landing area of a modern aircraft carrier, which is offset approximately 10 degrees (it varies somewhat by class) to port from the ship's centerline to provide for safe BOLTERs. Enables the simultaneous landing and launching of aircraft.
Angle of Attack :: A.K.A. Alpha, AOA. An engineering term represented by the Greek letter 'Alpha' (Α); measured as the angle between the airfoil chord line and the relative wind. Note spelling is not the same as the military phonetic for the letter 'A.' AOA is generally measured and reported in 'units,' an arbitrary quantity which differs from aircraft to aircraft. AOA has a tremendous import in the handling and behavior of the aircraft. Most commonly seen as an aviation term, although it is applicable to other fluid environments such as a ship's propeller in water.
Angle of Incidence :: The angle measured between the aircraft's longitudinal centerline and the chord line of the wing airfoil. This value changes throughout the span of most aircraft (WASHOUT).
Angle (Off) :: (1) (Aviation) The measure, in degrees, of how far off your opponent's 6 o'clock you are. Relative bearing from the enemy to you, measured from dead astern. If you are dead astern, at his six o'clock, angle-off is zero. If angle-off is twenty, you are twenty degrees off your opponent's six o'clock (relative bearing from him to you is either 160 or 200).
Angles and Dangles :: Operating a submarine at steep angles of ascent and descent, as well as the performance of rapid turns (a submerged submarine in a tight turn will bank in the same fashion as an aircraft).
Angles Fighter :: Air to air maneuvering tactics which emphasize turning and rolling maneuvers. Angles tactics favor highly-maneuverable aircraft. Contrast with ENERGY FIGHTER.
Anti-Smash Light :: The rotating or flashing red anti-collision beacon on an aircraft.
AOA :: ANGLE OF ATTACK; an engineering term represented by the Greek letter 'Alpha' (Α).
AOW :: Auxiliaryman Of (the) Watch. Also called 'The Aux' (pronounced 'ox').
A-Pole :: (Aviation) The SLANT RANGE, in feet, from the launching aircraft to the target at the point where the missile begins its active-guidance terminal phase (if so equipped). Indicates the range at which the launching aircraft can maneuver without fear of losing radar lock and therefore missile guidance.
ARAB :: (UK) Arrogant Regular Army Bastard.
Arizona :: No anti-radiation missile ordnance remaining.
Arresting Gear :: Mechanism used to rapidly bring an aircraft to a halt aboard ship or ashore. In field use (i.e. ashore), A-gear may be a device as simple as lengths of chain connected to a CROSS-DECK PENDANT, though this type of installation is becoming less common. The chain arrestment device (A.K.A. 'chain gear') is usually referred to as 'overrun gear', as it acts to stop an aircraft which is about to run off of the end of the prepared runway surface (which area is called "The Overrun." Other types of arresting gear, ashore and afloat, involve complicated braking mechanisms.
Arse Bandit :: (UK) Homosexual.
Artificer :: (RN) Engineering technician.
ASAP :: As Soon As Possible. Depending on service and country, may be pronounced by being spoken as a word, 'A-sap,' the first 'a' being given the long sound, or essentially by being spelled aloud.
Ashcan :: A depth charge which is cylindrical in shape. Contrast with 'TEARDROP.'
ASW :: Anti-Submarine Warfare.
As You Were :: A command to a formation which contravenes a previous command; a statement made by one about to correct himself.
Athwartships :: Moving or placed from side to side aboard ship, or straddling a particular position. At right angles to the ship's longitudinal centerline.
At Loggerheads :: A serious difference of opinion. A Loggerhead is two iron balls attached by an iron rod, which was heated and used for melting pitch. Sailors sometimes used them as weapons to settle a grudge, i.e. when fighting they were 'at loggerheads.'
Auto Dog :: (USN) Soft serve ice cream, due to its similarity in appearance (at least when having chocolate flavor) to a pile of dog feces.
Autorotation :: (1) A method of making an emergency landing in a helicopter which has experienced engine failure. Energy is stored in the rotor as rotational momentum, then expended to slow the decent and cushion the landing. (2) Facetiously, a way for a helicopter pilot to keep his hands and feet occupied as he plummets to his death.
Attitude :: Orientation of an aircraft with respect to the horizon (pitch and roll).
Attitude Indicator :: Artificial horizon, an instrument which provides aircraft attitude (pitch/roll), and sometimes heading, reference for instrument flight.
AUX :: Pronounced 'ox', with short 'o' sound. (1) Verbal shorthand for 'auxiliary', as when referring to a machinery space, e.g. 'Aux One'. (2) Alternate form of AOW.
Avast :: A command which means, basically, 'Stop what you're doing.' This term appears to be from the French 'Haud Vast,' literally 'hold fast.'
Aweigh :: (sometimes seen, improperly, as 'away') When a ship raises (weighs) anchor, the anchor is said to be aweigh as soon as it is no longer in contact with the sea bottom. The traditional (and extremely old) joke runs "What does a ship weigh?" referring to its mass or size. The only proper answer to the question is, of course, "Anchor." Anchor Parts
AWOL Bag :: A small canvas or vinyl bag used to carry clothing or personal items while on weekend liberty.

B : BRAVO

Baby Shit :: Yellowish, evil-smelling grease.
Back Afty :: (RN) Anything to do with the nuclear power plant or the people who operate it. Contrast with CONER. See NUKE.
Back in Battery :: Originally an artillery term for a gun which has completed its recoil/postfiring cycle and is ready to fire again. Common additional usage now is to be 'ready to go,' or recovered. Also seen as 'Back to Battery' or 'Return to Battery.' "I set my hair on fire last night, but five hours' rack time and I'm back in battery."
Backing :: (1) Operating astern propulsion machinery. (2) A change of wind direction in the counter-clockwise direction (shifting to the left, as one looks into the wind).
Back to the Taxpayers :: Where you send an aircraft that has crashed or that you eject from.
Bag :: (1) Get, or collect: "Let's go bag some traps." (2) Stop, or leave: "Let's bag this project."
Bagger :: (1) One who bags, e.g. a "Hop Bagger" is one who tries to get more than his share of hops (flights). (2) One who does not pull his own weight; a lazy person.
Baggywrinkle :: Anti-chafing gear, especially for the rigging of a sailing ship.
Bag Nasty :: Sack lunch.
Ball (the) :: The glowing image projected by the FRESNEL LENS. Gives glideslope reference while on landing approach. Short for MEATBALL. As used today, the Ball is yellow unless the aircraft is dangerously low, in which case it is red and flashing.
Ballbuster :: (1) Something difficult. (2) A sexually teasing woman. (3) A safety harness used when working aloft, referring to the crotch strap of such a device.
Ball Call :: A radio transmission from a carrier pilot reporting that he has sighted the BALL during approach to the carrier. Typically consists of SIDE NUMBER, aircraft type (to ensure proper ARRESTING GEAR settings), and amount of fuel onboard in thousands of pounds, e.g. '205 Tomcat ball, 3.5'.
Balls (or Four Balls) :: Midnight, which in the military's 24-hour timekeeping system may be written as '0000,' although writing midnight as '2400' is perhaps more common.
Balls Out :: Refers to an early design of engine governor, in which a pair of masses (balls) on a vertical axle spun at an increasing rate as engine speed increased. Centrifugal acceleration threw the masses outward; the faster the engine speed, the farther from centerline the balls, so 'balls out' refers to maximum possible engine speed.
Balls to Four :: Midnight to 4 a.m. watch.
Balls to the Wall :: Maximum speed, or maximum effort.
BAM :: Originally this term meant Bad-Ass Marine. It has since come to mean Broad-Ass Marine, i.e. a woman Marine, but I recommend you make sure she doesn't hear you use the term. Compare with BOSNIA.
Banca Boat :: Term for any small native watercraft, especially in the Western Pacific or Indian Ocean/Persian Gulf. Actually somewhat redundant, as 'Banca' is from the Tagalog, literally 'boat.'
Bandit :: (1) Air contact positively identified as hostile. (2) (RCN) A sailor often in trouble.
Bang Out :: (UK) Eject.
Bang Seat :: (UK) Ejection seat.
Banjo :: (1) (RN) A sandwich. Also 'sarnie' or 'butty' (the latter, perhaps, from the practice of putting butter on the bread instead of mayonnaise as is usually done in the U.S.). (2) (USN) An aircraft nickname for the F-2 Banshee fighter. (3) During WWII, a device used aboard U.S. submarines as a visual aid during approach to a torpedo attack.
Banyan :: (RCN/UK) A barbecue or party on the flight deck, usually with steaks and beer. The term is derived from 'banian', a garment worn by an East Indian sect which neither kills nor eats meat ('Banyan' (note spelling) is a species of tree). In the 18th century, the British navy denied its sailors meat on Mondays, Wednesdays, and Fridays; these days were known as 'banian (or Banyan) days.' The term has now come to mean just the opposite. The USN term for a shipboard barbecue is STEEL BEACH (though, sadly, without the beer).
Bar Hog :: A woman who hangs out in bars (regardless of appearance).
Barrack Stanchion :: (RNZN) A sailor who rarely goes to sea.
Barricade (Barrier) :: (1) A device vaguely similar to (but much larger than) a tennis net, which can be rigged and used to stop an aircraft which is unable to TRAP (due to a defective or damaged arresting hook, damaged landing gear, etc). (2) In the days of the STRAIGHT DECK CARRIER, when it was not possible to BOLTER, the barricade was a series of devices rigged during normal landing operations to prevent an aircraft which had failed to TRAP from smashing into THE PACK, graduating from a low barrier which just engaged the landing gear, all the way to a device more similar to the contemporary one which ensured the aircraft would be stopped prior to running into aircraft already stopped on deck.
Basement :: The hangar bay of an aircraft carrier.
Basha :: (UK) An improvised shelter.
Batten Down :: Make fast, secure, or shut. Cargo hatches often do not have hinged, attached covers. In such case, hatch covers are separate pieces which are laid over the hatch opening, then made fast with battens (pieces of timber). This is still the practice aboard bulk (i.e. non-container) cargo ships.
Battle Cover :: The steel cover for a port or deadlight.
Bat Turn :: (Aviation) A very tight turn, reminiscent of the instantaneous 180 degree turns of the batmobile on the old Batman television series.
BB Stacker :: Generically, any ORDIE. One who handles ordnance, ammo, or explosives; an Aviation Ordnanceman. See REDSHIRT.
Beach :: Noun or verb, the shore, or to be put ashore. 'He screwed the pooch bigtime and they beached him.'
Beagle :: (RN/RAN) Wardroom steward.
(On her) Beam Ends :: Strictly speaking, when a ship has gone through 90 degrees of roll, where her decks are vertical. In such case a ship could capsize (roll completely over). Commonly used to refer to extreme rolls, even if less than 90 degrees.
Bear A Hand :: Make haste.
Bearing Drift :: The movement, left or right, of the bearing to an object in motion relative to your platform. It is an immediate indication of risk to you; if an object has no bearing drift and range is decreasing (referred to as CBDR, or Constant Bearing Decreasing Range), you will collide unless one or another (or both) platforms maneuver. Similarly, slow bearing drift may indicate an unsafe condition if the range is short.
Bearing Only Launch :: Launch of a weapon with only azimuth data. The missile flies up the bearing line looking for the target, and attacks the first detected object which meets its target parameters.
Behind the Power Curve :: (1) Not meeting expectations. (2) An airspeed lower than that for maximum lift over drag (the most efficient point of the wing's performance curve); at such a performance point, the aircraft requires more power to go slower while remaining in level flight.
Belay :: (1) Stop. (2) Make fast. Derived from the practice of tying a line off (making it fast) using a belaying pin. (3) Disregard, as in 'belay my last.'
Bells :: (1) A system for denoting the time aboard ship. Each bell represents half an hour, and bells are rung in pairs when possible; five bells in the morning watch (0630 hours, or 6:30 a.m.) would be rung as ding-ding, ding-ding, ding. Bells are normally rung over the 1MC during working hours only. (2) Speed orders to the engine room, from the days when moving the engine order telegraph rang a bell in the engine room. 'Ready to answer bells' means the engineering plant is ready for maneuvering orders.
Bell Tapper :: One who is habitually a few minutes late, especially when relieving the watch.
Beltway Bandit :: A company, or an employee of same, located near Washington, DC, which serves the defense industry. Many of the employees are former military personnel or military retirees.
Benny :: A treat or reward, derived from 'benefit.'
Benny Sugg :: (USN) Beneficial Suggestion program, a program where personnel were rewarded for making suggestions to improve some aspect of military life, usually involving living conditions.
Beno Box :: Patrol station in the Eastern Mediterranean in the '80s. Occupied by various Carrier Battlegroups and Amphibious Groups. The BENO Box was notorious for long on-station assignments, during which time there would 'Be No Liberty, Be No Women, Be No Nothing!'
Bend :: A knot.
Bend On :: Attach, as in tying two lines together. Can also refer to speed, "They bent on 30 knots and got the hell out of there."
Bent :: Radio PROCEDURE WORD. Broken or inoperative, as 'My gadget is bent.'
Better Dead Than Looking Bad :: The credo of the naval aviator (and, likely, all military aviators).
Between the Devil and The Deep Blue (Sea) :: See 'Devil to Pay'
BFM :: Basic Fighter Maneuvers. Simple maneuvers (turns, climbs, dives, skids, etc.) which can be combined to make up more complex ones.
Bib :: Term for the flap hanging from the rear shoulders of the jumper top of the CRACKERJACK USN enlisted uniform.
Big Chicken Dinner :: Bad Conduct Discharge. In many ways, equivalent to a felony conviction.
Bight :: (1) A loop in, or slack part of, a line. (2) A curve or bend in a shoreline, or a small body of water formed by same.
Bilge :: (1) The area below the deck gratings in the lowest spaces of the ship, where things, especially liquids, tend to collect. (2) To fail or do poorly. "Poor Smitty bilged the quiz." (3) To name a classmate or shipmate involved in wrongdoing, or to identify a mistake made by someone else.
Bilge Diving :: Working in the bilges of a ship, or cleaning same.
Bilge Rat :: Someone who works in the engineering spaces.
Bin Rat :: (RCN) A person who works in Stores (supply).
Bingo :: (1) Fuel level or status requiring either an immediate return to base or vector to a tanker, as 'bingo fuel'. As a verb, the act of returning to base or a tanker because of low fuel state.
Binnacle :: A pedestal which supports a compass. Typically found next to or in front of the ship's wheel.
Binnacle List :: Sick list; a listing of the names of the men currently in sick bay and unable to perform their duties due to sickness or injury. This list was originally to be found attached to the binnacle.
Biologics :: The sounds generated by sea life, when picked up on sonar.
Bird Colonel :: A full colonel (O-6 paygrade), whose collar device is a silver eagle, as compared to a lieutenant colonel, whose collar device is a silver oak leaf.
Bird Farm :: Aircraft carrier.
Birds :: (1) Term for the collar device of a USN/USCGS Captain or USMC/USAF/USA Colonel (O-6 paygrade), a silver eagle. (2) (RCN) Punishment consisting of confinement to the ship, base, etc., or sailors under punishment (derived from 'jailbird.') (3) Generic, airplane. (4) Missiles, especially in the surface warfare community.
Birds Free :: Missiles may be fired at any contact not positively identified as friendly.
Birds Tight :: Missiles may be fired only at contacts positively identified as hostile.
Bitchbox :: (USN) Intercom or amplified circuit used to communicate between spaces of the ship.

Bitter End :: Properly, the free or loose end of a line. Originally, the bitter end of a mooring line was taken to the bitts to secure it.
Bittersweet :: A radio call signifying that friendly aircraft are in danger from a surface AAW missile launch, or that the presence of friendly aircraft is preventing a missile shot at a BANDIT.
Bitts :: A shipboard mooring fixture comprised of a pair of cylindrical posts. Similar to a pair of BOLLARDs.
Black and Bitter :: Coffee, no sugar or cream added.
Black and Sweet :: Coffee with sugar.
Black Cat :: During World War Two, a PBY Catalina which was painted black and used for night reconnaissance patrol.
Black Cat Merchant :: (RN) Someone who is always exaggerating.
Black-Hand Gang :: SNIPE. Older (ca. WW II), less politically-correct form is 'Black Gang.' Originally, it referred to the appearance of men who had been handling or working around coal, but the term has come to refer to the engine room crew. During WWII, members of the Black Gang were issued black 'Dixie Cups' instead of white ones, and were therefore sometimes called 'Black Hats.'
Black-shoe :: Member of the surface or submarine community. Until recently, the only approved footwear for these communities was black in color. More recently, brown footwear is optional, but seldom seen due to tradition.
Black Water :: Sewage.
Blank Flange :: (1) A plate bolted onto an open pipe to prevent flooding or leaks while work is performed on a piping system. (2) Pancakes. (3) A.K.A. Blank File, someone who acts like an idiot.
Bleed Air :: In gas turbine engines, compressed air that is removed ('bled') from the compressor section at various points. Can be used for various applications, such as maintaining clean airflow in the engine, anti-icing, air conditioning, or to provide start air to another engine.
Blind :: Advisory call that an aircraft has lost visual contact with another friendly aircraft or ground position (opposite of Visual), as "Two's blind" (I have lost sight of my flight lead).
Blivet :: (1) Traditionally, "Ten pounds of shit in a five-pound sack." (2) A rubber fuel bladder. (3) A modified droptank (may be purpose-built or a field modification) used to haul small cargo, especially in tactical aircraft, or used to haul dangerous or toxic cargo outside of the aircraft.

A top blow removes scum and floating contaminants, a bottom blow removes sludge. (2) To backflush and clean a SEACHEST. (3) The process of removing excess pressure from a system, or venting it completely.
Blower :: Afterburner.
Blow Through :: (Aviation) Noun or verb, when an intercepting aircraft does not turn at the MERGE to continue the engagement, but continues straight ahead. Refusing an engagement.
Blue Bandit :: During Vietnam War, a US radio codeword for the MiG-21 'Fishbed.'

Adjustments in deflection usually result in a hit soon after. If it's you being bracketed, you had better do something (i.e. maneuver radically) fast! Contrast with STRADDLE.
Bracket and Halving :: A method of correcting the FALL OF SHOT in gunnery. For example, say a salvo falls left of the target; a 'spot' (aim correction) is made using right deflection, and the next salvo falls to the right of the target.

Burnthrough :: Noun or verb, the point at which a radar overcomes jamming. As long as the radar transmitter is stronger than the jammer transmitter (which is nearly always the case), as range decreases the radar's echoed signals will eventually be stronger than the jammer transmissions. At this point, burnthrough occurs and the radar will once again 'see' the target in spite of the jamming.

Butt Kit :: Ashtray.
Button (numeral) :: Preset radio channel, as "Packard, go button three."
By and Large :: Colloquial term meaning 'For the most part.' Origin of the term seems to be that a ship was considered particularly seaworthy if it could sail both 'by' (close to the wind) and 'large' (broad to or before the wind).
By His Lights :: In the nautical Rules of the Road, a ship uses lights at night to indicate its status, e.g. 'restricted in ability to maneuver,' 'constrained by draft,' 'towing alongside,' and so on. Therefore, "by his lights" you can predict to some extent the actions of the vessel.

Cold Enough to Freeze The Balls Off A Brass Monkey :: This term has nothing to do with testicles or primates, and a good deal of debate remains to this day regarding the origin of the phrase. In the days of smoothbore cannon, particularly ashore, ready-use cannon balls were stored near the guns. Ashore, the balls were stacked in a 'monkey,' a metal frame which was laid on the deck to help contain the bottom layer of the pyramid of cannon balls. Monkeys were typically made of brass (though monkeys made of rope were used as well). In extremely cold temperatures, the brass monkey shrank more than the iron cannon balls, and the stack of balls would collapse, or perhaps ice which formed under the balls pushed them up enough to break them loose. The root of the debate is whether such an event is possible at all, though the phrase appears to be more a traditional exaggeration than an engineering possibility. Aboard ship, cannonballs were more typically stored in SHOT GARLANDS, horizontal racks.
Cold Iron :: An engineering term meaning that the entire engineering plant has been secured. Lighting off boilers and getting steam up has always been an involved and lengthy operation, requiring anywhere from an hour to even longer before the ship could get underway. In time of war, being caught 'cold iron' could be tactically disastrous (cf. the Pearl Harbor air raid). With the increasing usage of gas turbines, this is less of an issue; a gas turbine ship can get underway within minutes if the lube oil systems are warm.

Conn :: Has several uses, all to do with control of the ship. (1) As 'Conning Officer,' that individual is legally responsible for the safe and proper usage of steering and engine orders to ensure the safe navigation of the ship. (2) (Submarines) Obsolete, the term used to refer to the conning tower, a structure built atop the hull from which periscope attacks on shipping were conducted. In more modern times, 'the conn' refers to the submarine's control center, an analogous compartment located within the pressure hull. (3) In general, the area of the ship from which conning orders are given.
Conning :: (1) Giving orders regarding the maneuvers of a ship. See CONN. (2) (Aviation) Generating a contrail.

Cook Off :: A serious casualty, the premature detonation of a loaded (naval or shore artillery) gun round caused by the residual heat within a HOT GUN. In a cook-off, the powder charge ignites all at once, rather than progressively from the rear of the shell casing as from the normal action of the primer. Similarly, the shell's BURSTING CHARGE may be initiated by this residual heat.

The ball moves vertically on the Fresnel lens array as the aircraft moves up and down the glideslope; a high ball, when the ball is above the datum lights, indicates that the aircraft is above the optimum glideslope. If the ball is lined up with the datum lights, the aircraft is correctly positioned on the glideslope. The ball appears red if the pilot gets dangerously low. The Fresnel lens assembly also has red lights mounted on it which can be used to give WAVEOFF and CUT commands. Fresnel lens installations are also found on almost all Naval Air Station runways.

Head :: Marine toilet. In their original form, toilet facilities were found right forward in the bows, so that the smell would be blown downwind and away from the ship (since sailing ships could not lie directly into the wind when underway). The extreme fore part of a ship was known as the 'beakhead,' which may have been shortened to 'head' over time.

Hooker :: Fishing craft.
Hook Point :: The part of the tailhook that actually engages the wires. It is replaced periodically, as it is worn down by contact with the deck or by field arrestment. Field traps are particularly rough on the hook point, as it is common practice to touch down well prior to the gear and roll into it, and length of rollout in field arrestment gear is much longer. As the hook is held down against the deck by a gas-pressurized snubber, wear is accelerated.

Illumination Round :: Star shell
IMC :: Instrument Meteorological Conditions. A set of FAA-defined criteria for inflight visibility.
Indexer :: (Aviation) The indicator lights mounted on a carrier aircraft's glare shield to indicate AOA during an approach to landing. The light array consists of a red 'fast' (AOA too low) indication (an upward-pointing chevron) at the bottom of the array, a green 'slow' (AOA too high) indication (a downward-pointing chevron) at the top, and a yellow on-speed indication (a circle or 'donut') in the center. It is generally active only when the landing gear are deployed. The same light pattern is sometimes echoed on an external array on or near the nose gear, so that aircraft AOA can be determined by the LSO.

Aircraft damage can result.
In-Flight Refueling :: Replenishing an aircraft's fuel supply in flight. US Navy systems (as well those of numerous other countries) use the 'probe and drogue' system where a hose is streamed aft of the tanker aircraft. The receiving aircraft then plugs into the drogue (also called 'the basket') and receives fuel. The US Air Force uses the 'boom' method, which has a much higher rate of fuel delivery. In this method, the receiving aircraft flies in close formation aft of and just below the tanker aircraft. A boom operator ('boomer') aboard the tanker aligns the boom via control surfaces and plugs it into a receptacle on the receiving aircraft.

Can be a noun (for the system or static tendency) or a verb, to use the system to change longitudinal (fore and aft) or lateral (side to side) balance. In aircraft, trim is usually accomplished by the adjustment of small surfaces ('tabs') on the flight control surfaces, although the entire control surface is moved on some types. In submarines, trim is usually accomplished by pumping fluids (water or fuel, usually) from one tank to another, or by moving weights such as stores from one compartment to another.
Trim Party :: A prank often perpetrated on a newly-qualled Dive Officer or Chief of the Watch, where men and other weights are shifted fore and aft to affect the trim of the boat.
