After the attack by Japan at Pearl Harbor, Hawaii, on December 7, 1941, Huntington Beach, along with many other coastal cities, mobilized to help the war effort. The U.S. Navy installed a submarine lookout post on the pier, along with a heavy caliber machine gun. When the war was over, all military equipment was removed and the pier was returned for public use. In 1983 and on 7 January 1988, Pacific storms destroyed the pier and the "End Cafe". Fluor/Daniel Consultants of Irvine conducted a study on the structural stability of the pier and the pier was declared unsafe. It was closed in July of that year. A community group called P.I.E.R. (Persons Interested in Expediting Reconstruction) was organized to raise funds for the pier's reconstruction. P.I.E.R. raised over $100,000 by selling T-shirts and other merchandise with the P.I.E.R. logo. An additional $92,000 was donated by the community of Anjo, Japan, a Huntington Beach Sister City.
