Carrier (1999)

by Clancy, Tom - Nf

  G-Force One G is the force exerted by Earth’s gravity on stationary objects at sea level. High-energy maneuvers can subject the aircraft and pilot to as much as 9 Gs. Some advanced missiles can pull as much as 60 Gs in a turn.

  GBU Guided Bomb Unit. General U.S. term for precision-guided munitions.

  GBU-29/30/31/32 JDAM Joint Direct Attack Munition. A general-purpose bomb or penetration warhead, with inertial/GPS guidance package in the tail cone. Initial operational capability planned for 1999. Navy requirement is 12,000 bombs; Air Force requirement is for 62,000.

  Geosynchronous Also called “geostationary.” A satellite in equatorial orbit at an altitude of 35,786 km (about 22,230 miles) will take 24 hours to circle the Earth. In 24 hours the Earth rotates once on its axis, so the satellite will appear to be “fixed” over the same point on the earth.

  “Glass” Cockpit Design that replaces individual flight gauges and instruments with multi-function electronic display screens. A few mechanical gauges are usually retained for emergency backup.

  Goldwater-Nichols Common name for the Military Reform Act of 1986, which created a series of Unified Commands cutting across traditional service boundaries and strengthened the power of the Chairman of the Joint Chiefs of Staff.

  GPS Global Positioning System. A constellation of 24 satellites in inclined earth orbits, which continuously broadcast navigational signals synchronized by ultra-precise atomic clocks. At least four satellites are usually in transit across the sky visible from any point on Earth outside the Polar Regions. A specialized computer built into a portable receiver can derive highly accurate position and velocity information by correlating data from three or more satellites. An encoded part of the signal is reserved for military use. A similar, incomplete, Russian system is called GLONASS.

  HARM AGM-88 High Speed Anti-Radiation Missile, produced by Texas Instruments. Mach 2+. 146-1b blast-fragmentation warhead. Typically fired 35 to 55 miles from target, but maximum range is greater. First used in combat in April 1986 raid on Libya; 40 missiles fired.

  Have Blue Original Lockheed “Skunk Works” prototype for the F-117 Stealth fighter. Considerably smaller than the production aircraft, and still highly classified.

  HEI High Explosive Incendiary, a type of ammunition commonly used with air-to-air guns.

  HOTAS Hands on Throttle and Stick. A cockpit flight control unit that allows the pilot to regulate engine power settings and steering commands with one hand.

  HS Helicopter Antisubmarine Squadron.

  HSL Helicopter Antisubmarine Squadron, Light.

  HUD Heads-Up Display: a transparent screen above the cockpit instruments on which critical flight, target, and weapons information is projected, so that the pilot need not look down to read gauges and displays during an engagement. Current HUD technology provides wide-angle display of radar and sensor data.

  IIR Imaging Infrared. An electro-optical device similar to a video camera that “sees” small differences in temperature and displays them as levels of contrast or false colors on a operator’s display screen.

  ILS Instrument Landing System. A radio-frequency device installed at some airfields that assists the pilot of a suitably equipped aircraft in landing during conditions of poor visibility.

  INS Inertial Navigation System. A device that determines location and velocity by sensing the acceleration and direction of every movement since the system was initialized or updated at a known point. Conventional INS systems using mechanical gyroscopes are subject to “drift” after hours of continuous operation. Ring-laser gyros sense motion by measuring the frequency shift of laser pulses in two counter-rotating rings, and are much more accurate. The advantage of an INS is that it requires no external transmission to determine location.

  Interdiction Use of airpower to disrupt or prevent the movement of enemy military units and supplies by attacking transportation routes, vehicles, and bridges deep in the enemy rear.

  IOC Initial Operational Capability. The point in the life cycle of a weapon system when it officially enters service and is considered ready for combat, with all training, spare parts, technical manuals, and software complete. The more complex the system, the greater the chance that the originally scheduled IOC will slip.

  IRBM Intermediate Range Ballistic Missile. A rocket (typically two-stage) designed to deliver a warhead over regional rather than intercontinental distances. This class of weapons was eliminated by treaty and obsolescence from U.S. and Russian strategic forces, but is rapidly proliferating in various world trouble spots, despite international efforts to limit the export of ballistic missile technologies.

  JCS Joint Chiefs of Staff. The senior U.S. military command level, responsible for advising the President on matters of national defense. The JCS consists of a Chairman, who may be drawn from any service, the Chief of Naval Operations, the Chief of Staff of the Army, the Commandant of the Marine Corps, and the Chief of Staff of the Air Force. JFACC Joint Forces Air Component Commander. The officer who has operational control over all air units and air assets assigned to a theater of operations. The JFACC is typically drawn from the service that has the greatest amount of airpower in the area of operations, and reports directly to the theater Commander in Chief.

  JP-5 Standard U.S. jet fuel. A petroleum distillate similar to kerosene.

  JTF Joint Task Force: a military unit composed of elements of two or more services, commanded by a relatively senior officer. JTFs may be organized for a specific mission, or maintained as semi-permanent organizations, such as the anti-drug JTF-4 based in Florida.

  KC-10 Extender Heavy tanker/transport based on Boeing DC-10 wide-body commercial airliner. 59 aircraft in service, some modified with drogue refueling hose reel as well as tail boom. Three CF6 turbofan engines. Maximum takeoff weight is 590,000 lbs.

Forbidden by many international treaties that have been widely ignored.

  NCO Non-Commissioned Officer. An enlisted soldier, sailor, or airman with supervisory responsibility or technical qualifications. There are nine standardized enlisted pay grades, but each service has its own complex nomenclature for NCO ranks. In the navy these are petty officer, chief petty officer, senior chief petty officer, and master chief petty officer. The senior NCO on a vessel, regardless of rank, is informally known as “Command Master Chief.”

  “Nugget” Pilot jargon for an inexperienced aviator, or new person in the squadron.

  O&M Operations and Maintenance. A major budget item for all military units.

  OpTempo Operational tempo—subjective measure of the intensity of military operations. In combat high OpTempos can overwhelm the enemy’s ability to respond, at the risk of burning out your own forces. In peacetime a high OpTempo can adversely affect morale and exhaust budgeted funds.

  Ordnance Weapons, ammunition, or other consumable armament. Frequently misspelled.

  OTH Over the Horizon. Used in references to sensors and targeting. Distance to the visual horizon may be 20 miles from the masthead of a ship, or more than 200 miles from an aircraft at high altitude.

  PAA Primary Aircraft Authorized—the number of planes allocated to a unit for the performance of its operational mission. PAA is the basis for budgeting manpower, support equipment, and flying hours. In some cases, a unit may have fewer aircraft because of delivery schedule slippage or accidents. Units may also have more aircraft than their PAA, such as trainers, spare “maintenance floats,” or inoperable “hangar queens.”

  PAO Public Affairs Officer. Military staff officer responsible for media relations, coordination with civil authorities, VIP escort duties, and similar chores. The PAO of an aircraft carrier is typically a Navy lieutenant, supervising a small team of enlisted writers and media specialists.

  Paveway Generic term for laser-guided bombs. Made by Raytheon/Texas Instruments since 1968. Latest Paveway III version provides standoff range of 3-5 nm.

  PGM Precision Guided Munition. Commonly called a “smart bomb,” any weapon that uses electronic, electro-optical, inertial, or other advanced forms of terminal guidance to achieve a very high probability of hitting its target.

  Pitch Change of an aircraft’s attitude relative to its lateral axis (a line drawn from left to right through the center of gravity). Pitch up and the nose rises; pitch down and the nose drops.

  “Pucker Factor” Flight crew anxiety level. Typically related to highly stressful combat situations such as major aircraft system malfunctions while under fire from enemy missiles.

  Pylon A structure attached to the wing or fuselage of an aircraft that supports an engine, fuel tank, weapon, or external pod. The pylon itself may be removable, in which case it is attached to a “hard point” that provides a mechanical and electrical interface.

  RAM Radar Absorbing Material. Metal or metal-oxide particles or fibers embedded in synthetic resin applied as a coating or surface treatment on radar-reflective areas of a vehicle in order to reduce its radar cross

  section. A particular RAM formulation may be specific to a narrow band of the radar frequency spectrum.

  RIM-116A RAM RIM-116A Rolling Airframe Missile. Development began in 1975 as a joint U.S./German/Danish program. Entered service in June 1993 on USS Peleliu (LHA-5). Combines seeker head of Stinger SAM with motor, warhead, and fuse from AIM-9 Sidewinder. Angled tail fins cause the missile to spin in flight for stability. Range of around 5 nm, and carried in a 21-round box launcher.

  RO-RO Roll-on/Roll-off. A cargo ship with vehicle parking decks, flexible ramps, and special ventilation, allowing loaded vehicles to drive on or off under their own power.

  ROE Rules of Engagement. Guidance often determined at the highest levels of national government, regarding how and when warriors may employ their weapons. In air-to-air combat, ROE usually specify specific criteria for declaring a non-friendly aircraft as hostile. In air-to-ground combat, ROE usually forbids attacking targets likely to involve significant collateral damage to civilian populations or religious sites. Regardless of the ROE, the right of self-defense against direct armed attack is never denied.

  Roll Change of attitude relative to the longitudinal axis (a line drawn from nose to tail through the center of gravity). Roll to port and an aircraft tilts to the left; roll to starboard and it tilts to the right. Roll also describes a class of aerobatic maneuvers, such as the barrel roll.

  RWR Radar Warning Receiver. An electronic detector tuned to one or more hostile radar frequencies and linked to an alarm that alerts the pilot to the approximate direction, and possibly the type of threat. Similar in concept to automotive police radar detectors. Also known as a RHAW (Radar Homing and Warning Receiver).

  SAM Surface to Air Missile. A guided missile with the primary mission of engaging and destroying enemy aircraft. Most SAMs use rocket propulsion and some type of radar or infrared guidance.

  SAR Synthetic Aperture Radar. An aircraft radar (or operating mode of a multi-function radar) that can produce highly accurate ground maps.

  SCUD Western reporting name for the Soviet R-11 (SCUD-A) and R-17 (SCUD-B) short-range ballistic missiles. Based largely on captured WW II German technology. Range of 110-180 miles with 900-kg/1,980-1b warhead, with inaccurate inertial guidance. Can be transported and erected for launch by a large truck. Widely exported to Iraq, Nort
h Korea, and other Soviet client states. Iraq modified basic SCUD-B design to produce longer-ranged Al Abbas and Al Hussein missiles with much smaller warheads.

  SEAD Suppression of Enemy Air Defenses. This requires enticing the enemy to “light up” search and tracking radars, launch SAMs, or fire antiaircraft guns, which can then be targeted for destruction or neutralization by jamming and other countermeasures.

  SIGINT Signal Intelligence. Interception, decoding, and analysis of enemy communications traffic.

  Skunk Works® Lockheed’s Burbank, California, Advanced Development group, created during WW II by engineer Clarence “Kelly” Johnson. Developed the U-2, SR-71, F-117, and other secret aircraft. Lockheed Martin copyrights the name and skunk cartoon logo.

  Slat A long, narrow, moveable control surface, usually along the leading edge of the wing, to provide additional life during takeoff.

  Sortie The basic unit of airpower: one complete combat mission by one aircraft. “Sortie generation” is the ability of an air unit to re-arm, refuel, and service aircraft for repeated missions in a given period.

  Sparrow AIM-7 family of long-range radar-guided air-to-air missiles produced by Raytheon. Variants include the ship-launched Sea Sparrow.

  Stall Sudden lost of lift when the airflow separates from the wing surface; may be caused by a variety of maneuvers, such as climbing too steeply with insufficient thrust. “Compressor stall” is a different phenomenon that occurs inside a turbine engine.

  Stealth A combination of design features, technologies, and materials, some highly classified, designed to reduce the radar, visual, infrared, and acoustic signature of an aircraft, ship, or other vehicle. This can be taken to the point where effective enemy detection and countermeasures are extremely unlikely before the vehicle has completed its mission and escaped. The F-117A is the best-known modern example.

  STOVL Short Takeoff-Vertical Landing. Capability of certain vectored-thrust aircraft, notably the Harrier and variants of the future Joint Strike Fighter. Short takeoff is assisted by a fixed “ski-jump” ramp.
