Navy LPD-17 Flight II and LHA Amphibious Ship Programs: Background and Issues for Congress [Updated June 10, 2021] [open pdf - 1MB]
From the Introduction: "This report provides background information and issues for Congress on two types of amphibious ships being procured for the Navy: LPD [landing platform/dock]-17 Flight II class amphibious ships and LHA [landing helicopter assault]-type amphibious assault ships. Both types are built by Huntington Ingalls Industries/Ingalls Shipbuilding (HII/Ingalls) of Pascagoula, MS. The Navy's LPD-17 Flight II and LHA shipbuilding programs pose multiple oversight issues for Congress. Congress's decisions on the LPD-17 Flight II and LHA programs could affect Navy capabilities and funding requirements and the shipbuilding industrial base. They could also have implications for the preservation and use of Congress's power of the purse under Article 1 of the Constitution, and for maintaining Congress as a coequal branch of government relative to the executive branch."
