SSN-23 in MSF at Kitsap(click to view full) Aug 11/08: The Watts-Healy Tibbitts joint venture in Honolulu, HI receives an initial $42.4 million increment to build a drive-in magnetic silencing facility at Beckoning Point, Naval Station Pearl Harbor. The 2nd increment will be funded in FY 2009 at $35.9 million, and the 3rd increment will be funded in 2010 at $6.6 million to finish the $84.8 million contract. The contract also contains an unexercised option, which would increase the cumulative contract value to $86.1 million. The reason behind these expensive facilities is simple. Any mass of iron stressed in the earth’s magnetic field becomes a magnet. Riveting and other construction activities magnetize a ship, as do some operational activities. That magnetization then changes gradually when the ship is underway, depending on its heading and location. A magnetized object can be detected, of course, and magnetic field changes can also be used as a trigger for weapons like mines and homing torpedoes. Magnetic Silencing Facilities provide deperming/ degaussing, which reduces the ship’s electromagnetic signature to a point that’s much closer to the earth’s natural level. Cryptome has a partial list of American MSFs, including some photos and links. Work will be […]
