Notes:
--'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
--Terms in ALL-CAPS have a separate listing.
--A great deal of variation in pronunciation may be experienced between services or between countries. For example, in the US Navy "ASAP" is spoken as a word, "eh' sap" (eh = long 'A' sound) while the US Army and U. S. Air Force essentially spell the word aloud, "eh ess eh pee."
--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 FAQ may not be for you. You have been warned.



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.
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.
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 an unaccelerated stall.
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).
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.
AEF/A - (USN submarine) Auxiliary Electrician Forward/Aft.
A.F.R.T.S. - Spoken as "a-farts", with long '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 - Aqueous Film Forming Foam. A fire-fighting agent which is mixed with water and sprayed on flammable liquids fires. Spoken "A triple-F". Aka 'Light Water' 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 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 - Auxiliary, Intelligence Gathering, aka 'Tattletale'. Refers to USSR 'trawlers' (or, more recently, 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. See also 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.
Airdale, airedale - Naval aviator, aka 'BROWNSHOE'. 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 stuff 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 (AKA Arctic Fits) - What results when trying to urinate through 6 inches' thickness of clothing with 3 inches of wedding tackle.
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 'launch' signal. This generally requires that the aircrew be seated in the aircraft at all times. There may also be aircraft/aircrews on alert fifteen, etc., in which cases the aircrew may be out of the aircraft but must be nearby.
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 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."
All Ahead Bendix - Traditionally, an engine order for "max tracks," i.e. as fast as she can go. The Engine Order Telegraph (q.v.) 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 "All Ahead Bendix" tends to irritate the Chief Engineer.
Alpha Mike Foxtrot - Acronym for "Adios, Motherfucker". Polite form: "Adios, My Friend." Also seen as initials, 'AMF.'
Amateur Night - The day after payday, when nothing seems to go right, especially shipboard evolutions.

Andrew (the) - (UK) Nickname for the Royal Navy. Refers to pressgang leader Andrew Miller who, it was said, owned the Royal Navy.
Angled Deck - The landing area of a modern aircraft carrier, which is offset 10 degrees to port from the ship's centerline to provide for safe BOLTERs. Aka 'angle deck', 'the angle.'
Angle of Attack - Abbreviated AOA, generally measured and reported in "units," an arbitrary quantity which differs from aircraft to aircraft. AOA is defined as the angle measured between the relative wind and the chord line of an airfoil, in a practical sense it measures how hard a wing is working. Essentially, AOA is the angle between the air movement (*not* the horizon!) and the aircraft's wing. Has a tremendous import in the handling and behavior of the aircraft. Aka 'Alpha', from the engineering notation for AOA. Primarily 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 (see WASHOUT).
Angles and Dangles - Operating a submarine at steep angles of ascent and descent, and to perform rapid turns (a submarine in a tight turn will bank in the same fashion as an aircraft).
Anti-Smash Light - The rotating or flashing anti-collision beacon on an aircraft.
AOA -Angle of Attack (q.v.).
AOW - Auxiliaryman Of (the) Watch. Also called 'The Aux'.
ARAB - (UK) Arrogant Regular Army Bastard.
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 (q.v.), though this type of installation is becoming less common. The chain arrestment device (aka "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. 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' given the long sound, or essentially by being spelled aloud.
Ashcan - A depth charge which is cylindrical in shape. See also "TEARDROP"
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.
AUX - Pronounced 'ox', with short 'o' sound. (1) Verbal shorthand for 'auxiliary', as when referring to a machinery space, '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. From the process of weighing anchor, the sequence of reports is usually as follows:
"Anchor's at short stay" - The ship has been pulled up to the anchor, but the anchor is still lying on the bottom, undisturbed.
"Anchor's 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's aweigh" - The anchor has left the bottom. Legally, at this point the ship is under way (not in contact with or attached to the ground), whether or not it is "making way" (moving through the water under its own power).
AWOL Bag - A small canvas or vinyl bag used to carry clothing or personal items while on weekend liberty.

Top

Baby Shit - Yellowish, evil-smelling grease.
Back Afty - (RN) Anything to do with the nuclear power plant or the people who operate it. 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).
Bag - (1) Get, or collect. "Let's go bag some traps." (2) Stop, or leave. "Let's bag this project."
Ball (the) - The glowing image projected by the FRESNEL LENS. Gives glideslope reference. Short for 'meatball,' the term for the red ball of light seen in the old mirror landing system which predated the Fresnel lens system. 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 harness used when working aloft.
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 - Four to midnight 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 do not recommend she hear you use the term. See also BOSNIA.
Banca Boat - Term for any small native craft, especially in the Western Pacific or Indian Ocean/Persian Gulf. '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, Butty - (1) (RN) A sandwich. Also 'sarnie'. (2) (USN) 'Banjo' is also a nickname for the F-2 Banshee fighter. (3) During WWII, a device used aboard U.S. submarines as a visual aid during approach to an 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.
Barrack Stanchion - (RNZN) A sailor who rarely goes to sea.
Barricade (the) - (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). Aka 'barrier'. (2) In the days of the straight-deck carriers, the barricade was a series of devices rigged during normal landing operations to prevent an aircraft which 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.
Basha - An improvised shelter.
Batten Down - Make fast, secure, or shut. Originally, deck hatches did not have hinged, attached covers. Hatch covers were separate pieces which were laid over the hatch opening, then made fast with battens (pieces of timber).
Battle Cover - The steel cover for a port or deadlight.
BB Stacker - Generically, any ORDIE.
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.
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, for example, you will collide unless one or another (or both) platforms maneuver (see CBDR). Similarly, slow bearing drift may not indicate a safe condition if the other object is close.
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.
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 of marking the time aboard ship. Each bell represents half an hour, and bells are rung in pairs, so 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 engine room 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!"
Bent - Radio pro word. Broken, or inoperative. E.g. "My gadget is broken."
Between the Devil and The Deep Blue (Sea) - See "Devil to Pay."
BFM - Basic Flight Maneuvers. Simple maneuvers (turns, climbs, dives, skids, etc.) which can be combined to make up more complex ones.
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.

Birds - (1) Term for the rank markings of a USN/USCGS Captain or USMC/USAF/USA Colonel (silver eagle, O-6 paygrade). (2) (RCN) Punishment consisting of confinement to the ship, base, etc., or sailors under punishment (derived from the slang term 'jailbird.') (3) Generic, airplane. (4) Missiles, especially in the surface warfare community.
Birds Free - Permission has been granted to fire missiles.
Birds Tight - Permission to fire is refused.
Bitchbox - (USN) Intercom or amplified circuit used to communicate between spaces of the ship.
Bitching Betty - The (usually female-voiced) cockpit warning system of many aircraft today.
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 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 - See 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) Someone who acts like an idiot (aka 'blank file').

Blonde and Bitter - Coffee with cream.
Blonde and Sweet - Coffee with cream and sugar.
Bloodhound - Radio codeword for Mark 46 ASW torpedo.
Blowdown - A generic engineering term which can be used as noun or verb. A cleaning and/or venting process. Some specific applications: (1) A process for cleaning water-sides of a boiler.

(3) The process of removing excess pressure from a system, or venting it completely.
Blow Through - (Aviation) Noun or verb, when an intercepting aircraft does not turn to continue the engagement but continues straight ahead. Refusing an engagement.
Blue Force - Friendly forces in a wargame exercise.
Bluejacket - See BLUE-SHIRT.

Blue-Shirt - (1) (aviation) Aviation Boatswain's Mate. During flight deck ops, wears a jersey color-coded blue. Responsible for positioning and chaining down aircraft. Aka 'Chock and Chain boys.' A type of KNUCKLEDRAGGER. Often a non-rated person. (2) Anyone E-6 or below wearing the dungaree uniform. Very similar to the more traditional term "Bluejacket," due to the Navy blue jacket issued with the dungaree uniform.
Blue Water - Literally, 'deep water,' or 'deep draft,' but more traditionally, 'away from land.' The opposite of BROWN WATER. A 'blue water navy' is capable of prosecuting battle away from shore-based support in vessels of sufficient size and endurance to do so safely.
Blue Water Ops - Flight operations conducted when beyond range of a BINGO or divert field. At this point it is literally sink or swim for the aircrew--if a successful trap or landing aboard cannot be made, the aircrew will have to eject, bail out, or ditch.
Boarding Rate - The percentage of carrier approaches that result in successful arrestments. May be counted for a pilot, a squadron, or an airwing.
Board - Oral examination board.
Boards - (1) (Aviation) Speed Brakes. (2) Shoulder boards (rank markings).
Boat - (1) Traditional term of reference for a submarine. (2) Traditional aviation term used to refer to an aircraft carrier. (3) Any small vessel incapable of making regular independent voyages on the high seas. The traditional differentiator is that "ships carry boats."
Boats - Boatswain's Mate.

Bogey Dope - Radio calls to the intercepting fighter giving data on the bogey's position, course, altitude, etc.
BOHICA - Acronym for "Bend Over, Here It Comes Again."
BOL - Bearing Only Launch (q.v.)
Bollard - A squat cylindrical fixture attached to a pier or quay, with small horizontal horns which are used for tying off lines. Used to secure lines, such as mooring lines.
Bolter - The go-around that occurs when the carrier plane's tailhook misses the wires. Only possible on modern carriers with an ANGLED DECK (q.v.). Prior to the advent of the angled deck, missed wires generally resulted in a BARRICADE engagement or a crash into the PACK.
Bomb (The) - (submarines) The oxygen generator system.
Bomber - See BOOMER.
Bonedome - Flight helmet. Aka 'hardhat', 'brain bucket'.
Boom - (1) (aviation) Sonic boom. (2) (USAF) The winged pipe extending aft and below a tanker aircraft. The wings are used to fly the boom into position to connect with the receiving aircraft, then the boom extends to make contact. Offers much higher rates of transfer than that found in the probe and drogue systems common to the USN and all other countries that employ inflight refueling.
Boomer - (1) (Naval) Ballistic missile submarine. Primary mission is nuclear deterrence. May also be seen as 'bomber.' (2) (USAF) The operator of the boom (q.v.).
Boomer Pin - See PATROL PIN.
Boomer Widow - The wife of a boomer sailor, if she chooses to stray while he's on patrol.
Boondockers - High-top (over the ankles) black shoes, worn as part of the working uniform.

(3) (Aviation) A location on the aircraft's datum line, often used as a center point for dogfight radar scan modes, or when telling the RIO to get a lockup, goddammit! (4) A radar mode which slaves the antenna scan to the aircraft boresight.
Boot - Rookie or newbie, as in 'boot Ensign.' Originated in the practice of referring to a new man as 'bootcamp,' rather than by name.
Bootneck (RN) - See ROYAL MARINE.
Boot Topping - The black paint used at the waterline of many warships. Separates the (above-water) hull paint from the anti-fouling underwater paint.
BOSNIA - Big Old Standard Navy Issue Ass. Refers to the size of the sterns of some (usually female) navy personnel.

Bosun - The phonetic spelling of 'boatswain.'
Bosun's Whistle (or Pipe) - A small metal whistle used to signal the announcement of important messages, or for ceremonial purposes.
Bounce - (1) Carrier landing practice. (2) (older usage) Surprise air-to-air attack by a fighter, usually from above and behind.
Bow Array - (Submarine) That part of the sub's sonar suite which is located in the bow.
Box the Compass - (1) To name all the points of the compass. (2) To face successively in all directions, as when a ship loses steerage and drifts aimlessly.
Boy Butter - A light tan grease used by weapons types on torpedoes.
Bracket - In shipboard gunnery, a bracket results when one salvo lands to the left of the target and the next lands to the right. Adjustments in deflection usually result in a hit soon after.
Bracket and Halving - A method of correcting the aim of shipboard gunnery. For example, say a salvo falls left of the target; a "spot" (an aim correction) is made using right deflection, and the next salvo falls to the right of the target. Another spot is applied back to the left, half the amount of the previous correction. In this way, the fall of shot is walked onto the target.
Brain Fart - Conceptual discontinuity. Loss of the bubble. Polite forms: 'brain fade', 'brain cramp'.
Brass - Officers, especially senior officers.
Bravo Zulu - Phonetic pronunciation of 'BZ' from the NATO signals codes. Signifies 'Good Job' or 'Well Done.'
Break - (1) Maneuver used by pilots of tactical aircraft to slow to traffic pattern speed. Typically, a 180-degree turn to the downwind leg at 4.5-6 G's (depending on speed of entry and type of aircraft). This maneuver minimizes the amount of time an aircraft spends in the traffic pattern, one of the most dangerous flight regimes. It also maximizes the rate at which aircraft can arrive at the airport.

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. 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.
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. 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.

May or may not result in the aircraft entering a spin.
Deuce - (or Ma Deuce) Browning cal fifty heavy machine gun.
(The) Devil to Pay - Originally, the saying was "The devil to pay and no pitch hot." In the old wooden-hulled ships, 'devil' seams joined the external hull timbers with the deck planking; there are also references to a devil seam back aft, where the hull timbers join at the rudder post. Seams were caulked or sealed-paid-by jamming oakum fiber into the gaps, then smearing the seam with melted pitch or tar. If one of these seams worked open in rough weather, a great deal of water could be shipped before it was repaired.
