LSD - Whidbey Island / Ha
Function: Dock landing ships which support amphibious operations.
History: The Whidbey Island Class ships (LSDs 44 to 48) were built by Avondale Industries of New Orleans, which was also selected to build the cargo version of the ship, the Harpers Ferry Class (LSD 49 to LSD 52).
Description: The Whidbey Island Class ships were built to transport and launch air-cushioned landing craft (LCAC). The ships also provide docking and repair facilities for LCACs and for a range of conventional military, utility and personnel landing craft and also provide landing facilities for helicopters. The Harpers Ferry Class provides an increased cargo capacity and reduces the number of air-cushioned landing craft carried from four to two. As well as 340 crew members, the ships have capacity for 500 troops.
The last of this class, USS Pearl Harbor (LSD 52), was commissioned in May 1998
Under a U.S. Navy program, the Whidbey Island (LSD 41) was fitted with a Quick Reaction Combat Capability/Ship Self Defense System to provide it with a more co-ordinated and effective defence against attack by anti-ship missiles and aircraft. SSDS integrates the weapon control system, the close-in weapon system, the air search radar, the electronic warfare systems and the anti-air missile system. The latest ship of the class, the USS Pearl Harbor, has already been fitted with SSDS, and all twelve ships will be retrofitted with the SSDS by the year 2002.
