The U.S. Navy awarded HII's Ingalls Shipbuilding division a $283 million lead yard support contract on April 28, 2026, to begin pre-construction activities on the FF(X) class frigate — the ship the Navy selected to replace the Constellation-class program it cancelled in November 2025 after years of cost growth and schedule delays. The contract covers long-lead material procurement, design execution, and initial steel-cutting work at the Pascagoula, Mississippi shipyard, with the Navy targeting first-ship delivery by 2028. The award, confirmed in an HII press release and covered across defense trade press, marks the opening gun of what could be the most consequential Navy surface combatant program of the decade.

From Constellation's collapse to FF(X)

The Constellation-class frigate program — designated FFG(X) — was terminated by the Navy in November 2025 after the sole-source award to Fincantieri Marinette Marine in 2020 produced a ship program that by 2024 was more than 40 percent over its original cost estimate and running years behind its delivery schedule. The lead ship, USS Constellation (FFG-62), had still not been launched at the time of cancellation despite a contract signed six years earlier. Congress and the Navy ultimately concluded that the European-derived FREMM design was too difficult to Americanize for domestic shipyard production at the scale and price the Navy required.

In December 2025, the Navy awarded Ingalls Shipbuilding the right to design and build the FF(X) using a fundamentally different approach: leverage the Legend-class national security cutter (NSC), a design Ingalls had already delivered ten times to the U.S. Coast Guard. The NSC is a proven, domestically designed hull that Ingalls knows how to build at cost and on schedule. The FF(X) will be navalized — adding combat systems, weapons, and survivability features appropriate for a warship — but the baseline design risk is dramatically lower than the Constellation program's attempt to adapt a foreign frigate design for American production.

What the $283M covers

The April 28 lead yard support contract funds three main buckets of work. First, Ingalls will procure long-lead time materials — components like main reduction gears, propulsion shafting, and combat systems hardware that require eighteen to thirty-six months of production lead time and must be ordered well before construction begins to avoid delaying the shipbuilding schedule. Second, Ingalls engineers will advance the ship's design from the selected baseline to production-ready drawings, incorporating Navy-specific requirements for survivability, electronics, and weapons integration. Third, the shipyard will begin cutting and shaping raw steel to support the main structure foundation, allowing the construction sequencing plan to be validated and refined before full-rate production tooling is committed.

About 73 percent of the initial $80.6 million in obligated funding comes from the Navy's fiscal 2026 shipbuilding and conversion appropriation. The remaining 27 percent is funded from Navy research and development accounts, reflecting the design development component of the early work. The contract structure anticipates subsequent awards for full construction as design matures and long-lead deliveries begin arriving at Pascagoula.

The 2028 delivery goal

The Navy's stated goal of getting the first FF(X) in the water by 2028 is aggressive by historical shipbuilding standards. The Legend-class NSC baseline helps substantially: Ingalls has a proven build sequence, trained workforce, and established supplier relationships for that hull type. But navalization introduces complexity — combat systems integration, weapons mounting, and survivability modifications require coordination with the Navy's program office, combat systems integrators, and weapons system contractors who were not part of the Coast Guard cutter program. Industry observers at gCaptain and Naval News have noted that the 2028 target "reflects a smooth transition from design to production" assumption that leaves little margin for the inevitable engineering questions that arise when adapting a civilian platform for warfighting use.

The schedule is also shaped by the Navy's surface fleet readiness concerns. The service is operating with a frigate gap — the last Oliver Hazard Perry-class frigate was retired in 2015, and the Navy has been relying on destroyers to cover escort missions that frigates would traditionally handle. Each year of delay in FF(X) delivery extends that gap and increases the operational burden on a destroyer fleet that is itself under strain.

Ingalls' broader shipbuilding posture

The FF(X) award comes as Ingalls navigates a busy period. The shipyard holds active contracts for Arleigh Burke-class destroyers, San Antonio-class amphibious ships, and the America-class amphibious assault ship program. Adding a new frigate production line to that workload is a significant workforce and facilities challenge. HII has signaled plans to invest in expanded capacity at Pascagoula to support the FF(X) ramp, but the specifics of that investment have not been publicly disclosed. The ATSP V microelectronics contract that includes HII Mission Technologies — a separate award from the Defense Microelectronics Activity for advanced technology support — gives the broader HII enterprise additional revenue diversification as the FF(X) construction program matures.

The Navy's decision to go sole-source to Ingalls reflects both the urgency of the 2028 schedule goal and the limited domestic shipyard capacity for surface combatants. Bath Iron Works, the other major surface combatant builder, is fully committed to Arleigh Burke production and its DDG(X) next-generation destroyer development work. Austal USA and other smaller yards do not have the infrastructure for a frigate of the FF(X)'s complexity. Ingalls was the only yard positioned to take on the program at the pace the Navy requires.

What it means for contractors

  • Combat systems integrators — particularly Lockheed Martin, Raytheon, and L3Harris — should expect solicitations for FF(X) weapons, sensors, and electronic warfare systems as the design matures through late 2026 and into 2027.
  • Long-lead material suppliers for marine propulsion, electrical systems, and structural steel should be aware that Ingalls is now in active procurement mode; the $80.6M initial obligation includes long-lead buys that will hit supplier pipelines in the near term.
  • Small business subcontractors with Coast Guard NSC program experience are well-positioned to participate in FF(X) production as Ingalls leverages its existing supply chain.
  • Firms that participated in the now-cancelled Constellation-class program should review any intellectual property or tooling they developed for that effort — there may be value in that work for the navalization phase of FF(X), and proactive outreach to the Ingalls team is appropriate.
