LPD Flight II

Huntington Ingalls Industries (HII) has revised its plan to use the hull form of the San Antonio-class amphibious warship as a candidate for the Navy’s next generation amphibious warship – LX(R).

HII’s new Flight IIA modifies the original LPD-17 design by removing some of the higher end capabilities of the San Antonio and creating a so-called amphibious truck to replace the existing class of aging Whidbey Island and Harpers Ferry 16,000-ton landing ship docks (LSD).
