Here’s a concise update on the FF(X) frigate program based on the latest publicly reported items up to May 2026.
Direct answer
- The U.S. Navy is pursuing a new small surface combatant, FF(X), based on the Coast Guard’s Legend-class National Security Cutter design. The service aims to have the first hull in the water around 2028 and to deliver initial units into service by the early 2030s, with ongoing development to add modules and growth capacity in later flights. This follows the decision to wind down the Constellation-class program and shift to a more rapid, lower-risk frigate approach built around an established hull design. [Source: multiple outlets reporting Navy statements and defense coverage in early 2026, including Navy press materials and analyses of the FY2027 budget actions.]
Key context and components
- Basis and rationale: FF(X) is intended to fill a gap in the fleet by providing a smaller, more agile platform focused on surface warfare, with modular payloads and capacity to integrate unmanned systems. It is described as a complement to larger destroyers rather than a one-for-one replacement. [Sources noting Navy framing and mission concept around distributed maritime operations.]
- Procurement and production: The program shift places the lead hull at the Huntington Ingalls Industries (HII) Ingalls yard, with a plan to leverage existing NSC components to accelerate construction and reduce lead times. A Critical Design Review was anticipated in 2026 to set baseline design for initial production. [Reports tied to 2025–2026 timeline and Navy budget briefings.]
- Capability growth: Flight-based development is planned, with Flight I limited but Flight II expected to add a fixed vertical launch system and expanded anti-submarine warfare and air-defense capabilities. Containerized payload modules remain a core concept for early configurations, enabling rapid reconfiguration for different missions. [Analyses of program trajectories and Navy briefings.]
What to watch next
- Delivery milestones: Monitor Navy announcements and Congressional/DoD budget documents for the formal commitment to the 2028 in-water target, the sequencing of two lead ships under a potential sole-source arrangement, and any updates to the 22-ship plan for a broader small surface combatant fleet. [Sources discussing budget-driven milestones and contract actions in 2026.]
- Flight evolutions: Expect updates on Flight I vs Flight II configurations, potential inclusion of VLS, and integration pathways for unmanned systems and payload pods as the program matures. [Analyses of program design approaches and lessons from earlier frigate efforts.]
Illustration
- Concept sketch: FF(X) built on a National Security Cutter hull with modular mission packages and containerized weapons—this enables a cheaper, faster path to a reconfigurable light surface combatant compared with more bespoke designs. This high-level concept has appeared across several defense-press discussions in early 2026. [General program description across multiple sources.]
