A distinct special-mission class

GAO’s 2026 attack-submarine maintenance cost analysis excludes Seawolf from its main comparisons because its mission set differs. Virginia or Los Angeles operating costs should not be substituted.

Open research: Separately scoped historical R&D total remains unverified; missing is not zero. A platform-specific contract award with verified date, value and scope remains to be added. Quantity and cost figures retain their source dates. Historical snapshots are not a census of operational availability on the review date. No international purchase record verified in this profile; this is not proof that no foreign operators exist.
