Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individuals ...

Pearl Harbor
Pearl Harbor is an American lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. It was often visited by the Naval fleet of the United States, before it was acquired from the Hawaiian Kingdom by the U.S. with the signing of the Reciprocity Treaty of 1875.

Shakedown (testing)
A shakedown is a period of testing or a trial journey undergone by a ship, aircraft or other craft and its crew before being declared operational. Statistically, a proportion of the components will fail after a relatively short period of use, and those that survive this period can be expected to last for a much longer, and more importantly, predictable life-span. For example, if a bolt has a hidden flaw introduced during manufacturing, it will not be as reliable as other bolts of the same type. Example procedures Racing cars Most racing cars require a "shakedown" test before being used at a race meeting. For example, on May 3, 2006, Luca Badoer performed shakedowns on all three of Ferrari's Formula One cars at the Fiorano Circuit, in preparation for the European Grand Prix at the Nürburgring. Badoer was the Ferrari F1 team's test driver at the time, while the main drivers were Michael Schumacher and Felipe Massa. Aircraft Aircraft shakedowns check avionics, flight contro ...
