Subtopics

• Acoustic energy [r]: Add brief definition or description
  • Microphone [r]: Acoustic-to-electric transducer or sensor that converts sound into an electrical signal, the most basic design uses a thin membrane which vibrates in response to sound pressure. ^[e]
  • Sonar [r]: A contraction of sound navigation and ranging, formally includes the active mode in which a pulse goes out and a receiver measures the echo. Also includes hydrophones or passive, listen-only systems. ^[e]
• Gravity [r]: The tendency of objects with mass to accelerate toward each other. ^[e]
• Hydrography [r]: Add brief definition or description
• Magnetic field [r]: Vector field H caused by permanent magnets, conduction currents, and displacement currents. ^[e]
  • Magnetometer [r]: A scientific instrument used to measure the strength and/or direction of the magnetic field in the vicinity of the instrument. ^[e]
  • Superconducting Quantum Interference Device [r]: A highly sensitive device for detecting and measuring magnetic fields ^[e]
• Maritime patrol aircraft [r]: Very long range, usually land-based, aircraft optimized for sea surveillance, originally principally for anti-submarine warfare but often with anti-surface warfare capabilities; newer types also have land and littoral surveillance roles ^[e]
• Meteorology [r]: The interdisciplinary scientific study of the processes and phenomena of the atmosphere, including weather studies and forecasting ^[e]
  • Special operations weather [r]: Part of the U.S. Air Force Special Operations Command, this is an additional qualification for weather technicians, such that they can operate deep behind enemy lines, plan the weather aspects of military operations, and train others in basic weather skills ^[e]
• Oceanography [r]: The scientific study of the oceans. ^[e]
  • Bathythermograph [r]: Add brief definition or description
  • Thermocline [r]: A boundary layer between water at different temperatures in deep bodies of water. ^[e]
• Seismology [r]: Add brief definition or description

• Anti-submarine warfare [r]: Add brief definition or description
• Counter-rocket, artillery and mortar [r]: Military equipment and techniques to detect unguided rockets, artillery shells, and mortar rounds in flight, warn friendly forces that are threatened, and, with new methods, intercept and destroy the projectiles before they can do damage ^[e]
• Counterbattery [r]: Defense against enemy artillery involving identifying the point of origin of hostile fire and directing lethal force against it ^[e]
• National technical means of verification [r]: Euphemism principally for imagery intelligence satellites and other means of strategic arms control verification, principally because the Soviet Union did not want its public to know that they could not prevent Western observation of the state ^[e]
• Vietnam War military technology [r]: Add brief definition or description
