Mark 15 Torpedo
The Mark 15 torpedo, the standard American destroyer-launched torpedo of World War II, was very similar in design to the Mark 14 torpedo except that it was longer, heavier, and had greater range and a larger warhead. It was developed by the Naval Torpedo Station Newport concurrently with the Mark 14 and was first deployed in 1938. It replaced the Mark 8 torpedo on surface ships with tubes that could accommodate the longer Mark 15; this primarily included destroyers built after 1930. Older destroyers, primarily the ''Wickes'' and ''Clemson'' classes, continued to use the Mark 8, as did PT boats early in World War II. During the war 9,700 were produced at Newport and at the Naval Ordnance Station Forest Park, Illinois. The Mark 15 had the same basic design problems that plagued the Mark 14 for the first 20 months following U.S. entry into the war, though this was not realized nearly as quickly by the destroyer crews as it was by the submariners.

Type 93 Torpedo
The was a -diameter torpedo of the Imperial Japanese Navy (IJN), launched from surface ships. It is commonly referred to as the Long Lance by most modern English-language naval historians, a nickname given to it after the war by Samuel Eliot Morison, the chief historian of the U.S. Navy, who spent much of the war in the Pacific Theater. In Japanese references, the term is also used, in reference to its propulsion system. It was the most advanced naval torpedo in the world at the time. History and development The Type 93's development (in parallel with a submarine-launched model, the Type 95) began in Japan in 1928, under the auspices of Rear Admiral Kaneji Kishimoto and Captain Toshihide Asakuma. The torpedo design was inspired by the British oxygen-enriched torpedoes used on the s. At the time, the most powerful potential enemy of the Japanese Navy was the United States Navy's Pacific Fleet. The U.S. Navy's doctrine, presuming an invasion by Japan of the Philippines (an Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fleet Problem
The Fleet Problems are a series of naval exercises of the United States Navy conducted in the interwar period, and later resurrected by Pacific Fleet around 2014. The first twenty-one Fleet Problems — labeled with roman numerals as Fleet Problem I through Fleet Problem XXI — were conducted between 1923 and 1940. They were usually once-a-year exercises in which U.S. naval forces would engage in mock battles. One or more of the forces would play the part of a European or Asian navy. They were the culmination of the Navy's annual training maneuvers. Fleet Problem XXII, scheduled for 1941, was canceled because of the rising tensions with Japan that led to the US' entry into World War II. Following the outbreak of war, Fleet Problems underwent a prolonged hiatus, with other names being used to describe large American naval exercises. However, the term was revived in the 21st century under Admiral Scott H. Swift, with Fleet Problem XXIII through XXVIII taking place in the Pacific ...

Battle Of Vella Gulf
The was a naval battle of the Pacific campaign of World War II fought on the night of 6–7 August 1943 in Vella Gulf between Vella Lavella Island and Kolombangara Island in the Solomon Islands of the Southwest Pacific. This engagement was the first time that American destroyers were allowed to operate independently of the American cruiser force during the Pacific campaign. In the battle, six American destroyers engaged four Japanese destroyers attempting to reinforce Japanese troops on Kolombangara. The American warships closed the Japanese force undetected with the aid of radar and fired torpedoes, sinking three Japanese destroyers with no damage to American ships. Background After their victory in the Battle of Kolombangara on 13 July, the Japanese had established a powerful garrison of 12,400 around Vila on the southern tip of Kolombangara island in an attempt to block further island hopping by the American forces, which had taken Guadalcanal the previous year as part o ...

Phenolic Resin
Phenol formaldehyde resins (PF) or phenolic resins (also infrequently called phenoplasts) are synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde. Used as the basis for Bakelite, PFs were the first commercial synthetic resins (plastics). They have been widely used for the production of molded products including billiards, billiard balls, laboratory countertops, and as coatings and adhesives. They were at one time the primary material used for the production of circuit boards but have been largely replaced with Epoxy#Electrical systems and electronics, epoxy resins and fiberglass cloth, as with fire-resistant FR-4 circuit board materials. There are two main production methods. One reacts phenol and formaldehyde directly to produce a thermosetting polymer, thermosetting network polymer, while the other restricts the formaldehyde to produce a prepolymer known as novolac which can be moulded and then cured with the addition of more formaldehyde ...

Mark 6 Exploder
The Mark 6 exploder was a United States Navy torpedo exploder developed in the 1920s. It was the standard exploder of the Navy's Mark 14 torpedo and Mark 15 torpedo. Development Early torpedoes used contact exploders. A typical exploder had a firing pin that stuck out from the warhead and was restrained by a transverse shear pin. The torpedo would hit the target with enough energy to break the shear pin and allow the firing pin to strike a percussion cap that ultimately detonated the warhead. An arming impeller was an additional safety device: the firing pin could not move until the torpedo had traveled a preset distance. Just before World War I, the Bureau of Ordnance (commonly called BuOrd) started developing an inertial exploder. The result was the Mark 3 exploder. Warships employed defenses against torpedoes. A new technology, torpedo blisters, appeared on capital ships. The torpedo would explode against the blister but do little damage to the hull. Torpedo blisters wer ...

PT Boat
A PT boat (short for patrol torpedo boat) was a motor torpedo boat used by the United States Navy in World War II. It was small, fast, and inexpensive to build, valued for its maneuverability and speed but hampered at the beginning of the war by ineffective torpedoes, limited armament, and comparatively fragile construction that limited some of the variants to coastal waters. In the USN they were organized in Motor Torpedo Boat Squadrons (MTBRONs). The PT boat was very different from the first generation of torpedo boat, which had been developed at the end of the 19th century and featured a displacement hull form. These first generation torpedo boats rode low in the water, displaced up to 300 tons, and had a top speed of . During World War I Italy, the US, and UK developed the first high-performance gasoline-powered motor torpedo boats (often with top speeds over ) and corresponding torpedo tactics, but these projects were all quickly disbanded after the Armistice.
