The metal-fabrication skill cluster — welders, structural iron & steel workers, structural metal
fabricators/fitters, and layout workers/shipfitters — employs ~600,000 nationally. A job-ready
supply of ~37,000/yr meets demand of ~85,000/yr, a structurally widening shortfall.
Demand triangulated three independent ways (mission top-down, pipeline bottom-up, market signal);
government data sets the replacement floor only. Modeled trajectories are flagged.

Trajectory is modeled. Endpoints anchored to current ~48K cluster gap and the rising mission overlay (Columbia/Virginia/AUKUS/CHIPS/IIJA); intermediate years illustrative.

BLS Employment Projections (Aug 2025). Welders ~flat to slightly up, but 51-2041 projected −16% and rolled into the declining Assemblers parent. This is the lagged FLOOR — it excludes the mission overlay layered into demand above.

SOURCES & METHOD. Demand triangulated three independent ways: (A) mission top-down — Navy 174K shipyard workers/decade (DOD 45-Day Review via GAO-25-106286) × ~15.5% metal-fab cluster share of NAICS 336600 (BLS OEWS), plus Submarine Industrial Base 140K, CHIPS fab construction, IIJA, IRA, converted to annual cluster flows over the BLS replacement floor (~62K/yr); (B) pipeline bottom-up — NCES IPEDS (CIP 48.0508 welding ~50,561 completions 2023) + DOL RAPIDS + military (HT/SW, MOS 1316/91E) + ATDM, discounted for completion (~72%) and day-one readiness (~65%, per McKinsey Jan 2026 maritime study); (C) market signal — AWS ~82,500 openings/yr, HII Ingalls Mar-2026 wage hike (+18% immediate / +35–47% to 2031), Electric Boat 33K peak workforce. Methods A and C independently converge at ~80–90K/yr. Cost-of-vacancy uses BEA value-added per worker; multipliers NAM/IMPLAN ~5× manufacturing, MARAD 3.67× shipbuilding. Modeled trajectories (panels 02, 04) flagged in-panel. China ~200× shipbuilding capacity is un-triangulated on exact magnitude. Treat range and direction as robust; any single point as directional. — Full sourcing in the companion brief.
