We deliver full‑spectrum submarine modernization and repair services, including scheduled maintenance, complex overhauls, emergent global repairs, SHIPALT/ORDALT/TEMPALT execution, and engineering support performed within a NAVSEA‑authorized SUBSAFE program.

Yes. Our teams operate under a NAVSEA‑authorized SUBSAFE program and provide NAVSEA Note 5000‑authorized support for modernization, overhaul, and engineering activities across all U.S. Navy submarine platforms.

Absolutely. We perform depot‑level availabilities, emergent global repairs, and rapid‑response technical support to keep submarine systems mission ready.

We execute Ship, Ordnance, and Temporary Alterations (SHIPALTs, ORDALTs, and TEMPALTs), including engineering, installation, testing, and documentation aligned with NAVSEA standards.

We collaborate with both public and private shipyards to provide waterfront engineering, on‑site test support, SUBSAFE and DSS maintenance, structural modifications, propulsion system replacements, and modernization of critical systems such as VLS and sonar.

Our engineering capabilities include end‑to‑end design and execution, DSS logistics planning, PRM overhaul, TEMPALT engineering, technical work document development, project engineer oversight, and Level III NDT services (UT, PT, ET, MT, VT).

We specialize in precision repairs and upgrades across air, seawater, hydraulic, and trim/drain systems, submarine control systems (fairwater planes and retractable bow planes), watertight doors and hatches, torpedo launch systems, sail systems, masts and antennas, hull framing, structural components, and support platforms for Virginia‑class submarines.

Yes. We perform SUBSAFE and Deep Submergence Systems (DSS) maintenance, ensuring compliance with NAVSEA requirements and maintaining the highest standards of safety and reliability

We combine SUBSAFE‑certified personnel, proven shipyard experience, precision engineering, and a zero‑defect execution culture. Our teams deliver reliable, high‑quality results for major availabilities, emergent repairs, and mission‑critical modernization projects.

Yes. We provide comprehensive lifecycle support, including DSS logistics planning, PRM overhaul, engineering documentation, rotatable asset support, and long‑term sustainment strategies for mission‑critical submarine components.
