A torpedo on a rail A detonator on a railway line in Belgium South African example. Typical uses of detonators include: A warning, caution or stop signal in dense fog, when signals are difficult to see; A warning of a train stopped on the line ahead by an incident or accident—the train crew are usually responsible for placing the detonators
A warning system is any system of biological or technical nature deployed by an individual or group to inform of a future danger. Its purpose is to enable the deployer of the warning system to prepare for the danger and act accordingly to mitigate or avoid it.
Torpedo defence includes evasive maneuvers, passive defense like torpedo belts, torpedo nets, torpedo bulges, and sonar torpedo sensors, "soft-kill" active countermeasures like sonar decoys and sonar jammers, and "hard-kill" active defenses, like anti-torpedo torpedoes similar in idea to missile defense systems.

Later, lightweight mounts for 12.75 in (32.4 cm) homing torpedoes were developed for anti-submarine use consisting of triple launch tubes used on the decks of ships. These were the 1960 Mk 32 torpedo launcher in the US and part of STWS (Shipborne Torpedo Weapon System) in the UK. Later a below-decks launcher was used by the RN.
A schematic cross-section of a ship with anti-torpedo bulges. [nb 1] USS Texas with its starboard torpedo blister removed during ongoing repair work, showing the original hull underneath. Essentially, the bulge is a compartmentalized, below the waterline sponson isolated from the ship's internal volume. It is part air-filled, and part free ...
A B61 nuclear bomb in various stages of assembly; the nuclear warhead is the bullet-shaped silver canister in the middle-left of the photograph.. 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.
It was to feature an open architecture, allowing it to serve as a host to other systems and support their information gathering and threat detection. [7] In 2012, the AN/SLQ-25D program became a part of the Surface Ship Torpedo Defense (SSTD) program, a US Navy effort to field a system that could detect and destroy incoming torpedoes.
Early designs may have relied solely on an inertial guidance system. [9] [10] The initial design was intended for nuclear warhead delivery. Later designs reportedly include terminal guidance and conventional warheads. [7] The torpedo steers using four fins that skim the inner surface of the supercavitation gas bubble.
