[1]: 5  In early 2014, Huntington Ingalls Industries suggested a modified version of the San Antonio-class hull for the Navy's LX(R) amphibious warfare ship, which they designated as "LPD Flight IIA".

This design modified the San Antonio class by removing some of its higher-end capabilities, resulting in a design that had improved command and control features compared to the existing LSDs, half the medical spaces of the San Antonio class, a smaller hangar for stowing two MV-22 tilt rotor aircraft, no composite masts, two main propulsion diesel engines instead of four, two spots for Landing Craft Air Cushion hovercraft or one Landing Craft Utility boat, and a reduced troop capacity.

[2] In October 2014, Secretary of the Navy Ray Mabus signed an internal memo recommending that the LX(R) amphibious warfare ship be based on the existing San Antonio-class design.

[11] On 26 March 2019, Huntington Ingalls announced the award of a US$1.47 billion, fixed-price incentive contract for LPD 30 (the 14th ship, and first of Flight II).
