Time Bomb
A time bomb (or a timebomb, time-bomb) is a bomb whose detonation is triggered by a timer. The use or attempted use of time bombs has been for various purposes including insurance fraud, terrorism, assassination, sabotage and warfare. They are a frequent plot device in thriller and action films as they offer a way of imparting a dramatic sense of urgency. Construction The explosive charge is the main component of any bomb, and makes up most of the size and weight of it. It is the damaging element of the bomb (along with any fragments or shrapnel the explosion might produce with its container or neighboring objects). The explosive charge is detonated by a detonator. A time bomb's timing mechanism may be professionally manufactured either separately or as part of the device, or it may be improvised from an ordinary household timer such as a wind-up alarm clock, wrist watch, digital kitchen timer, or notebook computer. The timer can be programmed to count up or count down (usua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

These are known as '' mechanical watches''. In the 1960s the electronic ''quartz watch'' was invented, powered by a battery and keeping time with a vibrating quartz crystal. By the 1980s it had taken over most of the watch market, in what became known as the quartz revolution (or the quartz crisis in Switzerland, whose renowned watch industry it decimate ...

Confederate Secret Service
The Confederate Secret Service refers to any of a number of official and semi-official secret service organizations and operations performed by the Confederate States of America during the American Civil War. Some of the organizations were directed by the Confederate government, others operated independently with government approval, while still others were either completely independent of the government or operated with only its tacit acknowledgment. By 1864, the Confederate government was attempting to gain control of the various operations that had developed since the beginning of the war, but often with little success. Secret legislation was put before the Confederate Congress to create an official Special and Secret Bureau of the War Department.

Turtle (submersible)
''Turtle'' (also called ''American Turtle'') was the world's first submersible vessel with a documented record of use in combat. It was built in 1775 by American David Bushnell (inventor), David Bushnell as a means of attaching Naval mine, explosive charges to ships in a harbor, for use against the Royal Navy during the American Revolutionary War. Connecticut Governor Jonathan Trumbull recommended the invention to George Washington, who provided funds and support for the development and testing of the machine. Several attempts were made using ''Turtle'' to affix explosives to the undersides of British warships in New York Harbor in 1776. All failed, and her transport ship was sunk later that year by the British with the submarine aboard. Bushnell claimed eventually to have recovered the machine, but its final fate is unknown. Modern replicas of ''Turtle'' have been constructed and are on display in the Connecticut River Museum, the U.S. Navy's Submarine Force Library and Muse ...

Frogman
A frogman is someone who is trained in scuba diving or swimming underwater. The term often applies more to professional rather than recreational divers, especially those working in a tactical capacity that includes military, and in some European countries, police work. Such personnel are also known by the more formal names of combat diver, combatant diver, or combat swimmer. The word ''frogman'' first arose in the stage name the "Fearless Frogman" of Paul Boyton in the 1870s and later was claimed by John Spence, an enlisted member of the U.S. Navy and member of the OSS Maritime Unit, to have been applied to him while he was training in a green waterproof suit. The term ''frogman'' is occasionally used to refer to a civilian scuba diver, such as in a police diving role. In the United Kingdom, police divers have often been called "police frogmen". Some countries' tactical diver organizations include a translation of the word ''frogman'' in their official names, e.g., Denmark ...

Limpet Mine
A limpet mine is a type of naval mine attached to a target by magnets. It is so named because of its superficial similarity to the shape of the limpet, a type of sea snail that clings tightly to rocks or other hard surfaces. A swimmer or diver may attach the mine, which is usually designed with hollow compartments to give the mine just slight negative buoyancy, making it easier to handle underwater. Types of fuses Usually limpet mines are set off by a time fuse. They may also have an anti-handling device, making the mine explode if removed from the hull by enemy divers or by explosions. Sometimes limpet mines have been fitted with a small turbine which would detonate the mine after the ship had sailed a certain distance, so that it was likely to sink in navigable channels (to make access difficult for other ships) or deep water (out of reach of easy salvage) and making determination of the cause of the sinking more difficult. Development In December 1938, a new unit was c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
