  • LPD program: delivered LPD 29 Richard M. McCool Jr.; building Harrisburg (LPD 30), Pittsburgh (LPD 31), Philadelphia (LPD 32); multi-ship procurement for LPD 33–35 in 2024.
  • DDG program: design agent for the Arleigh Burke-class with multiple recent ships (DDGs 128–135).
• Site and facilities: Pascagoula, MS on about 800 acres along the Pascagoula River; major manufacturing assets include a 660-ton gantry crane and a Land Based Test Facility; long-term lease of riverfront property.

Newport News Shipbuilding (nuclear)

• Designs, builds, refuels, overhauls, and inactivates nuclear-powered aircraft carriers and submarines.
• Exclusive prime contractor for nuclear aircraft carrier refueling and complex overhaul (RCOH).
• Carrier program history: designed and built over 31 aircraft carriers since 1933, including all ten Nimitz-class carriers; delivered USS Gerald R. Ford (CVN 78) in 2017. John F. Kennedy (CVN 79), Enterprise (CVN 80), and Doris Miller (CVN 81) are in various stages. CVN 82 and CVN 83 (William J. Clinton and George W. Bush) have NDAA 2026 authorizations and ongoing alignment.
• Submarines: capability to design and build nuclear-powered submarines. Virginia-class (SSN 774) program delivered multiple submarines in blocks IV–VI in collaboration with Electric Boat. Columbia-class (SSBN 826) program is in partnership with Electric Boat, with Build II underway for five additional boats.
• Site and capabilities: Newport News shipyard on about 550 acres near the James River and Chesapeake Bay; capabilities include engineering, design, construction, refueling, complex overhaul, and inactivation of carriers and submarines.

Mission Technologies

• Organized into four groups: All-Domain Operations, Warfare Systems, Global Security, and Unmanned Systems.
• Focus areas: C5ISR systems integration, sensors and data fusion, artificial intelligence and machine learning for defense, cybersecurity, software and hardware development, electronic warfare, unmanned underwater and surface systems, live/virtual/constructive training, and platform modernization.
• Market position: competes domestically and internationally against mid-to-large aerospace and defense firms and other tech-focused players; differentiators include advanced technology capabilities and competitive pricing.

Geography and assets

• Core U.S. facilities:
  • Ingalls: Pascagoula, MS (about 800 acres).
  • Newport News: Newport News, VA (about 550 acres).
• Recent acquisition: January 2025 — acquired W International SC, LLC and Vivid Empire SC, LLC (complex metal fabrication and ship module production) on a leased ~45-acre site near Charleston, SC, expanding manufacturing capacity and capabilities.
• Mission Technologies operations span the U.S., U.K., and Australia, with headquarters in Fairfax and McLean, VA, and a major presence in multiple U.S. cities and at customer sites.

Business model and risk posture

• Business depends heavily on U.S. Government contracts, with a mix of prime and subcontracting roles across shipbuilding and defense technology.
• Revenue concentration with the U.S. Navy is a material factor (81% in 2025).
• Operational risks include reliance on subcontractors and suppliers, labor considerations, complex program management, potential cost growth, and contract disputes. There are also risks related to funding, contract pricing, and regulatory compliance.
