Human torpedoHuman torpedoes or manned torpedoes are a type of diver propulsion vehicle on which the diver rides, generally in a seated position behind a fairing. They were used as secret naval weapons in World War II. The basic concept is still in use. The name was commonly used to refer to the weapons that Italy, and later (with a larger version) Britain, deployed in the Mediterranean and used to attack ships in enemy harbors. The human torpedo concept has occasionally been used by recreational divers, although this use is closer to midget submarines.
Type 95 torpedoThe Type 95 torpedo was a torpedo used by submarines of the Imperial Japanese Navy during World War II. The Type 95 was based on the Type 93 torpedo (Long Lance); its mod 1 had a smaller and mod 2 had a larger warhead size than the Type 93's . The Type 95 was similar to the U.S. Navy's contemporary Mark 16 hydrogen peroxide torpedo, which had a shorter range, slightly higher top speed and a larger and nearly twice as powerful war head at 580 Kilograms filled with TORPEX or HBX/HBX-3 Explosive.
Croatian NavyThe Croatian Navy (HRM; Hrvatska ratna mornarica, Croat war navy) is a branch of the Croatian Armed Forces. It was formed in 1991 from what Croatian forces managed to capture from the Yugoslav Navy during the breakup of Yugoslavia and Croatian War of Independence. In addition to mobile coastal missile launchers, today it operates 30 vessels, divided into the Navy Flotilla for traditional naval duties, and the Croatian Coast Guard. Five missile boats form the Croatian fleet's main offensive capability.
Pneumatic motorA pneumatic motor (air motor), or compressed air engine, is a type of motor which does mechanical work by expanding compressed air. Pneumatic motors generally convert the compressed air energy to mechanical work through either linear or rotary motion. Linear motion can come from either a diaphragm or piston actuator, while rotary motion is supplied by either a vane type air motor, piston air motor, air turbine or gear type motor.
Autonomous underwater vehicleAn autonomous underwater vehicle (AUV) is a robot that travels underwater without requiring continuous input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications an AUV is more often referred to as an unmanned undersea vehicle (UUV).
Motor gunboatThe motor gun boat (MGB) was a small, high-speed British military vessel of the Second World War, which was armed with a mix of guns, in contrast to the physically similar motor torpedo boat (MTB), whose main offensive weapon were torpedoes. The small size of the MGBs, and their high speed, made them difficult targets for German E-boats, though, like their opponents, they were limited by heavy weather, because they did not provide a stable-enough platform to aim the guns.
Coastal defence and fortificationCoastal defence (or defense) and coastal fortification are measures taken to provide protection against military attack at or near a coastline (or other shoreline), for example, fortifications and coastal artillery. Because an invading enemy normally requires a port or harbour to sustain operations, such defences are usually concentrated around such facilities, or places where such facilities could be constructed.
Guidance systemA guidance system is a virtual or physical device, or a group of devices implementing a controlling the movement of a ship, aircraft, missile, rocket, satellite, or any other moving object. Guidance is the process of calculating the changes in position, velocity, altitude, and/or rotation rates of a moving object required to follow a certain trajectory and/or altitude profile based on information about the object's state of motion.
Magnetic pistolMagnetic pistol is the term for the device on a torpedo or naval mine that detects its target by its magnetic field, and triggers the fuse for detonation. A device to detonate a torpedo or mine on contact with a ship or submarine is known as a contact pistol. A magnetic pistol on a mine will allow the mine to detonate in proximity to a target, rather than actual contact, allowing the mine to cover a larger effective area. A magnetic pistol on a torpedo allows the torpedo to detonate underneath the ship, instead of upon impact with the side of the ship.
New London, ConnecticutNew London is a seaport city and a port of entry on the northeast coast of the United States, located at the mouth of the Thames River in New London County, Connecticut. The city is part of the Southeastern Connecticut Planning Region. New London is home to the United States Coast Guard Academy, Connecticut College, Mitchell College, and The Williams School.
