Torpedo in the context of "Nose cone"

Anti-submarine warfare (ASW, or in the older form A/S) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, or destroy enemy submarines. Such operations are typically carried out to protect friendly shipping and coastal facilities from submarine attacks and to overcome blockades.

Successful ASW operations typically involve a combination of sensor and weapon technologies, along with effective deployment strategies and sufficiently trained personnel. Typically, sophisticated sonar equipment is used for first detecting, then classifying, locating, and tracking a target submarine. Sensors are therefore a key element of ASW. Common weapons for attacking submarines include torpedoes and naval mines, which can both be launched from an array of air, surface, and underwater platforms. ASW capabilities are often considered of significant strategic importance, particularly following provocative instances of unrestricted submarine warfare and the introduction of submarine-launched ballistic missiles, which greatly increased the lethality of submarines.

Hasan al-Rammah (Arabic: حسن الرماح, died 1295) was a Syrian Arab chemist and engineer during the Mamluk Sultanate who studied gunpowders and explosives, and sketched prototype instruments of warfare, including the first torpedo. Al-Rammah called his early torpedo "an egg which moves itself and burns." It was made of two sheet-pans of metal fastened together and filled with naphtha, metal filings, and potassium nitrate. It was intended to move across the surface of the water, propelled by a large rocket and kept on course by a small rudder.

Al-Rammah devised several new types of gunpowder, a new type of fuse, and two types of lighters.

Naval artillery is artillery mounted on a warship, originally used only for naval warfare and then subsequently used for more specialized roles in surface warfare such as naval gunfire support (NGFS) and anti-aircraft warfare (AAW) engagements. The term generally refers to powder-launched projectile-firing weapons and excludes self-propelled projectiles such as torpedoes, rockets, and missiles and those simply dropped overboard such as depth charges and naval mines.

A weapons platform is generally any structure, vehicle or mechanism on which a weapon can be installed (via various mounting mechanisms) for optimal stability and performance. The mounted weapons, the platform and all other associated supporting equipments together form the weapon system.

In more general use, a weapons platform could be structured around a gun, such as a gun turret on a ship, or bracing on an aircraft. For example, a jet aircraft is a weapons platform for missiles, bombs or autocannons, and the resultant weapon system is the fighter jet; a motorboat can serve as a weapons platform for automatic weapons, torpedoes and flamethrowers, resulting in weapon systems such as gunboats and fast attack crafts. Land vehicles, either wheeled, tracked or mixed, are also considered weapons platforms for grenade launchers, machine guns, recoilless guns and some missile launchers, which transform the vehicles into weapon systems such as armored cars (such as the Humvee), IFVs and technicals (improvised from civilian pickup trucks). In addition, artificial satellites have been proposed as potential space weapon platforms. These satellites could carry an arsenal of weapons, such as to threaten other countries with the possibility of an orbital nuclear strike (see Rods from God).

Kamikaze (神風; pronounced [kamiꜜkaze]; 'divine wind' or 'spirit wind'), officially Shinpū Tokubetsu Kōgekitai (神風特別攻撃隊; 'Divine Wind Special Attack Unit'), were a part of the Japanese Special Attack Units of military aviators who flew suicide attacks for the Empire of Japan against Allied naval vessels in the closing stages of the Pacific campaign of World War II, intending to destroy warships more effectively than with conventional air attacks. About 3,800 kamikaze pilots died during the war in attacks that killed more than 7,000 Allied naval personnel, sank several dozen warships, and damaged scores more. The term is used generically in modern warfare for an attacking vehicle, often unmanned, which is itself destroyed when attacking a target; for example, a kamikaze drone.

Kamikaze aircraft were pilot-guided explosive cruise missiles, either purpose-built or converted from conventional aircraft. Pilots would attempt to crash their aircraft into enemy ships in what was called a "body attack" (tai-atari) in aircraft loaded with bombs, torpedoes or other explosives. About 19 percent of kamikaze attacks were successful. The Japanese considered the goal of damaging or sinking large numbers of Allied ships to be a just reason for suicide attacks. By late 1944, Allied qualitative and quantitative superiority over the Japanese in both aircrew and aircraft meant that kamikaze attacks were more accurate than conventional airstrikes, and often caused more damage. Some kamikazes hit their targets even after their aircraft had been crippled.

A main battery is the primary weapon or group of weapons around which a warship is designed. As such, a main battery was historically a naval gun or group of guns used in volleys, as in the broadsides of cannon on a ship of the line. Later, this came to be turreted groups of similar large-caliber naval rifles. With the evolution of technology the term has come to encompass guided missiles and torpedoes as a warship's principal offensive weaponry, deployed both on surface ships and submarines.

A main battery features common parts, munition and fire control system across the weapons which it comprises.

A warhead is the section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb.
