The navy's not the only ones that used the term. Tanks in Vietnam also used the term, "Ron" was short for "rendezvous"...a meeting site (a place to link up). The term, "Ron site" was used a lot; example: "We've got a Ron site over that hill about 2 clicks, see ya in 2 hotels, out!"
Some terms used during the Vietnam War:
Hotels=Hours
Comic book=map
NDP=Night Defensive Position
Out=End of transmission
Over=Your turn to talk
H & R Fires=Harassment & Interdiction Fire
Recon By Fire=Shooting up the place prior to entering it
Thunder Run=Firing all tank guns while driving down the road
See website: Patrol Torpedo Boats (PT Boats)
Torpedoes were originally launched from torpedo boats in the 1870s. Although TBs were still used, by the Russo-Japanese War of 1904, Torpedo Boat Destroyers (TBDs) were more effective in launching torpedoes; as well as destroying TBs. Which is why they were called "destroyers", because they originally were designed to "destroy (kill)" torpedo boats.
Because they could be launched from the decks of a fast moving boat. Submarine technology wasn't available for service in the 19th century, so torpedo boats were used instead. To kill torpedo boats, "torpedo boat destoryers" were invented. These evolved into "destroyers", the first of which sunk their first all steel battleships during the Battle of Tsushima on 27 May 1905.
They were intended to protect the battleships and cruisers from attack by enemy torpedo boats. After the war torpedo boats became less of a threat, but destroyers were retained to protect the larger warships against two new threats; enemy aircraft and submarines.
PT stands for Patrol Boat. PT boats were small fast torpedo boats used by the United States Navy during WWII. Their small size gave them a speed advantage over larger vessels such as destroyers and frigates. They would use their speed and small size to there advantage and close in on the size of their target ship then launch a series of torpedo's usually 4 and then speed away. They had a 5 to 7 man crew and were armed with .50 cal heavy machine guns as well for engaging small vessels and anti aircraft defense.
The were used for reconnaissance bombing, ground support, ASW patrol, transportation, Air/Sea rescue, torpedo planes, Bomber/fighter interceptors and as fighters.
The US Navy's Riverine Forces were part of the US Navy's Brown Water Navy; only the second time it was created. The first time was the US Civil War (1861-1865). The Brown Water Navy (Riverine Forces) used: Swift Boats (PCF-Patrol Craft Fast, all aluminum 50' foot long boats); PBR's (Patrol Boat River-fiberglass 32 foot long boats); Alpha boats (ASPB-Assault Support Patrol Boats, all steel contructed boats); and Monitors (River Battleships).
A torpedo is a miltary weapon which is shot from a submarine, ship or patrol boat or dropped form an aircraft. Once dropped it races towards its target where its warhead explodes on contact with its target, usually another ship (although they have been fired against dams before, such as the Chosin reservoir.) Torpedoes are long and cylindrical in shape with propellors at one end to provide propulsion. They are still used by virtually every modern Navy. Torpedoes are named after a fish called the torpedo ray, so sailors refer to the torpedo weapon as a fish. Prior to the invention of the Whitehead Torpedo (the first modern torpedo), the term "torpedo" was often used for what we now term a naval mine. (Adm Farragut's famous quote "Damned the torpedos! Full speed ahead!" was in reference to a minefield).
War costs money! Money is used to build (in Vietnam's case): Swift Boats (these boats were built in Louisiana); PBRs (Patrol Boat River, built in Washington state); Monitors; Alpha Boats (ASPB-Assault Support Patrol Boats; these boats were built in Oregon); M48 Patton tanks (built in Detroit); ammunition/rifles/machineguns built in various plants thru out the continent...etc. etc. Once the war is over...so's your job.
The spar torpedo was first effectively used to sink ships during the US Civil War (1861). The automotive torpedo was first effectively used in the Russo-Turkish War (1877). The first major use of self propelled torpedoes (automotive torpedoes) was the Russo-Japanese War (1904-05). All torpedoes mentioned above were launched from torpedo boats or torpedo boat destroyers.
The British Royal Navy built the first boat to launch self-propelled torpedoes in 1877. They followed up with new designs right up till WW1 and on. The Italian Navy also built many early torpedo boats and used them to great effect in WW1.
The most famous of all of the German boats in WW2 was the U-boat, it was a kind of submarine that fired torpedo's and a ship before it could see it or even know that an enemy was nearby.
