From Citizendium, the Citizens' Compendium
- Guided missile : A weapon that flies through air or space, under its own power, which adjusts its course to hit its target.
- Naval warfare : The military history of the organized navies of the world from 300 BCE to the present.
- Anti-shipping missile : An air, surface (sea or land), or submarine-launched missile that can track and intercept a maneuvering ship target against the background of moving water
- Anti-submarine warfare : (ASW) In the context of naval warfare, the mission of attacking underwater vessels, from platforms under naval command and control.
- Anti-surface warfare : (ASuW) In the context of naval warfare, the mission of attacking surface vessels, from small boats to supertankers and aircraft carriers, from platforms under naval command and control
- Mine (naval warfare) : A naval explosive weapon that waits passively for a target to come into its range, and then detonates or releases a mobile weapon once its sensors detect an appropriate target
- Maritime patrol aircraft : 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
- Torpedo bomber : Now obsolete, but a naval bomber optimized for making a long, straight, slow and level approach to a target ship, to drop a heavy torpedo within a critical set of flight parameters
- Submarine : A ship or boat that can travel underwater
- Long Lance (torpedo) : WWII Japanese torpedo, straight-running and unguided, but longer-range and probably more accurate than any other torpedo of the war; also known as Type 93
- Type 93 (torpedo) : WWII Japanese torpedo, straight-running and unguided, but longer-range and probably more accurate than any other torpedo of the war; also known as Long Lance
- Shkval (torpedo) : Russian/Soviet torpedo of revolutionary design, traveling, at relatively short range, in bubble of supercavitation at speeds of hundreds of kilometers per hour; probably unguided and may have nuclear warhead
- Type 65 (torpedo) : Soviet/Russian guided torpedo, probably the largest in the world at 650mm diameter, designed to follow the wake of a large warship target, especially an aircraft carrier
- Mark 8 torpedo : Add brief definition or description
- Spearfish torpedo : Add brief definition or description
- Mark 46 torpedo : Lightweight antisubmarine torpedo, primarily air-dropped but also ship-launched for close-in defense
- Mark 48 torpedo : U.S. heavyweight submarine-launched torpedo with bidirectional wire link to launcher, and autonomous active sonar; later versions known as Mk 48 ADCAP (advanced capability); uses liquid monopropellant; can engage subsurface and surface targets
- Mark 50 torpedo : Add brief definition or description
- RUM-139 Vertical Launch ASROC : A surface-to-underwater missile consisting of a guided booster that delivers a homing antisubmarine torpedo to a distant location
- Torpedo bulge : An extension of the underwater armor of warships, intended to cause torpedoes to predetonate before their blast can affect the main armor; generally obsolete against modern weapons
- SLQ-25 : A towed deceptive decoy for protecting ships against acoustic-homing torpedoes
- Safety and survivability of naval vessels : Beyond the rules of the Safety of Life at Sea convention, protective measures, for naval vessels, against their own systems as well as enemy fire
- Surface-to-underwater missile : A means of launching an antisubmarine torpedo from a surface ship, often by an unguided rocket booster, moving it at greater speed and range than possible for a torpedo in the water, and releasing the guided torpedo over the approximate location of the target
- Underwater-to-underwater missile : A weapon launched by one submarine at another submarine, which has an intermediate part of its path in which it flies through the air rather than the water, or possibly through a steam bubble.
- Unguided rocket : A form of artillery weapon that uses a rocket motor to propel a warhead at a target, using no guidance once launched
- Warhead : That part of a military weapon, which actively moves to strike a target, that causes the desired destructive effect on the target
