Overview

Naval Systems & Shipbuilding covers shipyards and defense contractors designing, building, and overhauling naval combatants, submarines, auxiliary vessels, and shipboard combat systems. It is a consolidated, capital-intensive segment dominated by Huntington Ingalls and General Dynamics (submarines and surface combatants).

Demand is supported by a U.S. naval buildup — submarine and surface-combatant programs, including the AUKUS submarine commitment — and by sustainment and overhaul work. It is a long-cycle, program-driven business with significant capacity-expansion and workforce challenges.
