Torpedo Defense System
The torpedo belt was part of the Naval armour, armouring scheme in some warships between the 1920s and 1940s. It consisted of a series of lightly armoured compartments, extending laterally along a narrow belt that intersected the ship's waterline. In theory this belt would absorb the explosions from torpedoes, or any naval artillery shells that struck below the waterline, and thus minimize internal damage to the ship itself. Torpedo belts are also known as Side Protection Systems or SPS, or Torpedo Defense System or TDS. Background: insufficiency of belt armor Armoured warships (dreadnought battleships, armoured cruisers and later light cruiser, light and heavy cruiser, heavy cruisers) of the early 20th century carried their main protective armour above the waterline – the "belt armor, main belt" – which was intended to stop flat-trajectory gunfire from piercing the hull. Below the belt, the armour generally tapered away, to reduce overall weight. This, however, makes ...

Naval Armour
Naval armour refers to the various protections schemes employed by warships, and is distinguished from other kinds of armour. Naval sailing ships have had protection from weaponry since at least ancient times, when Greek and Roman warships used simple cladding. As weapons evolved and became more destructive, naval armour became an important part of warships. Korean and European ships began to use some iron plating in the 1500s. The first ironclad warship was created in 1859, and the pace of armour advancement accelerated quickly thereafter. The emergence of battleships around the turn of the 20th century saw ships become increasingly large and well armoured. Vast quantities of heavily armoured ships were used during the World Wars, and were crucial in the outcome. The emergence of guided missiles in the last part of the 20th century has greatly reduced the utility of armor, and most modern warships are now only lightly armored. Naval armour consists of many different designs, depe ...
