2nd Chinese Navy Demagnetizing Facility Located

A second Chinese Navy facility for degaussing submarines and others vessels has been located about 5 miles from Maocao Nong Navy base, home to some 19 Kilo Class conventional submarines.

The East Sea Fleet facility was built between August 2007 and March 2008.

The East Sea Fleet facility is the second known Chinese demagnetization facility. In April 2008, I identified the first such facility at the South Sea Fleet base near Yulin on Hainan Island.

The South Sea Fleet facility was constructed sometime between January 2006 and February 2008.

The two demagnetization facilities are similar but with differences. The South Sea Fleet facility is built in a c-shape, similar to the U.S. design. The East Sea Fleet facility, which is located in a river, consists of two parallel piers, perhaps to accommodate strong currents.The Purpose of Demagnetization

Demagnetization is conducted before deployment to remove residual magnetic fields in the metal of a vessel to make it harder to detect by other submarines and surface ships. It reduces the ship’s vulnerability to mines that are triggered by magnetic signals from metal hulls. Demagnetization apparently also can improve the speed of the vessel.

This is another upgrade for PLAN facilities and their strategic abilities. It allows for a better outcome than portable, shipborne systems. Read the whole article to get a feel for not just why degaussing is important, but why this shows China’s interests in becoming a full-on blue water Navy.

A U.S. SSBN is prepared for demagnetization at the Kitsap Naval Submarine Base near Bangor, Washington. The U.S. Navy has such facilities on both coasts.

    Well, that should be good news to Boeing, since they didn’t put MAD on the P-8.

    Deperming sure is a pain in the butt. All that mag tape has to be removed from the boat. Not to mention the old fashioned way of dragging cables around the hull.

      You got that right! This is a part of China’s long-term plan to upgrade their facilities and join the modern world with a blue-water Navy. Just another step in their long journey towards strategic influence in the Pacific.
