The Whidbey Island class dock landing ship is a dock landing ship of the United States Navy. Introduced to fleet service in 1985, this class of ship features a massive well deck for the transport of US Marine Corps vehicles and a large flight deck for the landing of helicopters or V-22 Ospreys. The well deck was designed to hold four LCAC hovercraft, five if the vehicle ramp is raised, for landing Marines. Recent deployments have instead filled the well deck with a combination of LCU(s), AAVs, Tanks, LARCs and other USMC vehicles and gear. The Whidbey Island class of ship also uniquely benefits from multiple cranes and a shallow draft that further make it ideal for participating in Amphibious operations.

As of 2009, all ships of the class are scheduled to undergo a midlife upgrade over the next five years to ensure that they remain in service through to 2038. The ships will be upgraded each year through 2013, and the last ship will be modernized in 2014. Ships homeported on the East Coast will undergo upgrades at Metro Machine Corp., while those on the West Coast will receive upgrades at General Dynamics National Steel and Shipbuilding Company in San Diego.[1]

Major elements of the upgrade package include diesel engine improvements, fuel and maintenance savings systems, engineering control systems, increased air conditioning and chill water capacity, and replacement of air compressors. The ships also replaced steam systems with all-electric functionality that will decrease maintenance effort and expense.[1]

The Whidbey Island (LSD 41) and Tortuga (LSD 46) are to be decommissioned during the FYDP 2013-2018 and the remaining ships of the class are to be retired before the end of their service lives.[2] However, recent unofficial reports state that the Whidbey Island (LSD 41) decommissioning date has been changed to 2021.[citation needed]
