USS "Point Defiance" (LSD-31) was a "Thomaston"-class dock landing ship of the United States Navy.
 She was named for a location in Pierce County, Washington, the site of a military reservation established by the U.S. Government in 1866.
 She was the second ship assigned that name, but the construction of the "Casa Grande"-class dock landing ship "Point Defiance" (LSD-23) was canceled on 17 August 1945.
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 United States Marine Corps (USMC) 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.
USS "Rushmore" (LSD-47) is a "Whidbey Island"-class dock landing ship of the United States Navy.
 She was the second Navy ship to be named for the Mount Rushmore National Memorial in the Black Hills of South Dakota.
 She is the seventh ship in her class of dock landing ships and the fourth ship in that class to serve in the United States Pacific Fleet.
The Bell Boeing V-22 Osprey is an American multi-mission, tiltrotor military aircraft with both vertical takeoff and landing (VTOL), and short takeoff and landing (STOL) capabilities.
 It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft.
A dock landing ship (also called landing ship, dock or LSD) is an amphibious warfare ship with a well dock to transport and launch landing craft and amphibious vehicles.
 Some ships with well decks, such as the Soviet Ivan Rogov class, also have bow doors to enable them to deliver vehicles directly onto a beach (like a Landing Ship, Tank).
 Modern dock landing ships also operate helicopters.
A Landing Ship, Dock (hull classification LSD) is a form of auxiliary warship designed to support amphibious operations.
 The Ashland class dock landing ship were the first of the type and were built during World War II.
USS "Whidbey Island" (LSD-41) is a "Whidbey Island"-class dock landing ship of the United States Navy.
 She was named for Whidbey Island, in Puget Sound, Washington, the location of NAS Whidbey Island; the name ultimately derives from the sailor, explorer and engineer Joseph Whidbey.
A vertical take-off and landing (VTOL) aircraft is one that can hover, take off, and land vertically.
 This classification can include a variety of types of aircraft including fixed-wing aircraft as well as helicopters and other aircraft with powered rotors, such as cyclogyros/cyclocopters and tiltrotors.
 Some VTOL aircraft can operate in other modes as well, such as CTOL (conventional take-off and landing), STOL (short take-off and landing), and/or STOVL (short take-off and vertical landing).
 Others, such as some helicopters, can only operate by VTOL, due to the aircraft lacking landing gear that can handle horizontal motion.
 VTOL is a subset of V/STOL (vertical and/or short take-off and landing).
The Project 1174 (Nosorog) class landing ship (NATO reporting name: Ivan Rogov) is a class of Soviet/Russian dock landing ships (Soviet classification: Large landing ship, Russian: БДК, большой десантный корабль ).
 They were built as part of the expansion of the Soviet Navy's amphibious warfare capabilities in the 1970s.
USS "Anchorage" (LSD-36) was the lead ship of the "Anchorage"-class dock landing ship of the United States Navy.
 In the ship's 34 years of service, she completed 19 deployments in the western Pacific and became the most decorated dock landing ship on the west coast.
