Torpedo

Compressed gas stored inside the torpedo is ejected out of the nose, and the torpedo “glides” through the water inside the bubble, remaining relatively dry.

Navy officials did add that some of the improvements to the torpedo relate to letting more water into the bottom of the torpedo as opposed to letting air out the top.

The CAT torpedo was designed to home in on the incoming torpedo and blast it short of its target.

Here's one of the four torpedo launchers in the torpedo room.

Along with lack of knowledge of the capabilities of the Long Lance torpedo, the US Navy was hampered by a deficiency it was initially unaware of: the unreliable Mark 15 torpedo for destroyers.

Another early torpedo boat, HNoMS Rap As originally built, Lightning had two drop collars to launch torpedoes; these were replaced in 1879 by a single torpedo tube in the bow.

By WW1, Whitehead's torpedo remained a worldwide success, and his company was able to maintain a monopoly on torpedo production.

Compressed air The Whitehead torpedo of 1866, the first successful self-propelled torpedo, used compressed air as its energy source.

Destroyers became so much more useful, having better seaworthiness and greater capabilities than torpedo boats, that they eventually replaced most torpedo boats.

During World War I the US and UK developed the first high-performance motor torpedo boats (often with top speeds over convert) and corresponding torpedo tactics, but these projects were all quickly disbanded with the Armistice.

Early use and World War I Navies originally built torpedo boat destroyers to protect against torpedo boats, but admirals soon appreciated the flexibility of the fast, multi-purpose vessels that resulted.

Endurance can be improved by ensuring a target can be effectively engaged by a single torpedo, which gave rise to the guided torpedo.

In October 1887 the first torpedo division was created at Wilhelmshaven and the second torpedo division based at Kiel.

In semi-active mode, a torpedo can be fired to the last known position or calculated position of a target, which is then acoustically illuminated ("pinged") once the torpedo is within attack range.

In the case of deck or tube launched torpedoes, the diameter of the torpedo is obviously a key factor in determining the suitability of a particular torpedo to a tube or launcher, similar to the caliber of the gun.

In the late 19th century, many navies started to build torpedo boats 30 to 50 m in length, armed with up to three torpedo launchers and small guns.

Lyon p. 8 Once destroyers became more than just catchers guarding an anchorage, it was realized that they were also ideal to take over the role of torpedo boats themselves, so they were fitted with torpedo tubes as well as guns.

One such weapon, called the Whitehead torpedo after its inventor, caused the word "torpedo" to apply to self-propelled underwater missiles as well as to static devices.

She was manned by a crew of 60. In terms of gunnery, speed and dimensions, the specialised design to chase torpedo boats and her high seas capabilities, Destructor was an important precursor to the torpedo boat destroyer.
