The LX(R) class (formerly LSD(X) class) is a class of amphibious warfare ships under development for the United States Navy, to be contracted from 2020, as a replacement for the current Whidbey Island-class and Harpers Ferry-class dock landing ships. [1]: (Summary)

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. [1] 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 tank landing ship ...

The San Antonio class is a class of amphibious transport docks, also called a "landing platform, dock" (LPD), used by the United States Navy.

These ships transport and launch amphibious craft and vehicles with their crews and embarked personnel in amphibious assault operations. LSD 41 was designed specifically to operate LC AC...

The Navy’s FY2012 30-year shipbuilding plan calls for the procurement of a new class of amphibious ship called the LSD(X) starting in FY2017. Some observers have suggested using the LPD-17 design as the basis for the LSD(X). Navy officials do not stress this option and instead appear more interested in developing an all-new design for the LSD(X).

The LX(R) class (formerly LSD(X) class) is a class of amphibious warfare ships under development for the United States Navy, to be contracted from 2020, as a replacement for the current Whidbey Island-class and Harpers Ferry-class dock landing ships.
