HII’s Ingalls Shipbuilding extends its distributed shipbuilding model to amphibious transport docks, signaling a shift toward modular construction for larger Navy vessels
Executive summary: HII’s Ingalls Shipbuilding expanded its distributed shipbuilding initiative to include modular unit construction for the U.S. Navy’s amphibious transport dock program, starting with LPD 32 Philadelphia. Applying modular construction to larger amphibious ships could lower unit costs, reduce build‑time risk, and expand industrial base participation in Navy shipbuilding.
Who is involved: Huntington Ingalls Industries (HII), Ingalls Shipbuilding division, U.S. Navy (specifically the LPD 32 program), and unspecified partner shipyards.
Likely next: Fabrication of modular units for LPD 32 will commence in 2026, with assembly at Ingalls following delivery of the first modules; HII may evaluate extending the distributed model to additional LPD hulls or other amphibious classes.
Huntington Ingalls Industries announced that its Ingalls Shipbuilding division will apply the distributed shipbuilding approach—previously used for destroyers—to the U.S. Navy’s amphibious transport dock program, beginning with LPD 32 Philadelphia. The strategy involves constructing hull modules at partner facilities and assembling them at the Ingalls yard. This expansion aims to leverage existing partner capacity and potentially improve schedule predictability for the Navy’s amphibious ship procurement.
