Tridentis LLC

Tridentis LLC, an Alexandria, Virginia-based for-profit limited liability company, provides naval architecture, marine engineering, and ship design and technical documentation services as a prime contractor (99% of recent awards) to the Department of the Navy and other maritime federal agencies. The vendor competes predominantly in full-and-open federal procurements, with recent small business set-aside work limited to a single Coast Guard delivery order and a December 2024 OASIS+ Total Small Business IDIQ award.

The vendor's customer base is heavily concentrated in Navy maritime engineering. The Department of the Navy Naval Sea Systems Command (NAVSEA) anchors the portfolio with 62 awards carrying $16.36 billion in combined potential value, while the Department of the Navy Military Sealift Command holds 67 awards valued at $84.6 million. These two Navy customers represent 98% of all awards. The Department of Homeland Security US Coast Guard, the General Services Administration, and the Department of Commerce National Oceanic and Atmospheric Administration account for the remaining active customer relationships. NAVSEA's dominance in dollar value reflects Tridentis's position on large parent IDIQs and delivery orders for ship systems engineering, whereas Military Sealift Command's higher award count reflects frequent smaller vessel architecture and maintenance task orders.

Tridentis holds prime positions on multiple Navy IDIQ vehicles. The top parent contracts are Indefinite Delivery Contract N4523A19D1301 (36 task orders, $19.6 million combined potential value), Indefinite Delivery Contract N0003314D8017 (33 task orders, $2.1 million), and Indefinite Delivery Contract N0003313D8032 (18 task orders, $752 thousand). The vendor also recently secured the GSA OASIS+ Total Small Business Set-Aside IDIQ on December 19, 2024, with a multi-billion-dollar ceiling covering seven functional domains including Management and Advisory, Technical and Engineering, Research and Development, Intelligence Services, Environmental Services, Facilities, and Logistics; the minimum contract guarantee is $2.5 million, and a 0.15% Contract Access Fee applies to all task orders.

Recent concrete work exemplifies the vendor's portfolio. A $4.6 million definitive contract awarded by the Department of the Army on July 15, 2026, calls for Tridentis to develop, maintain, and update vessel data for Military Sealift Command Core Fleet through vessel computer models, AutoCAD drawings, and trim and stability calculations, with performance through September 2029 and optional extension through March 2030 under a total small business set-aside. NAVSEA delivery orders span ship systems documentation, shipcheck and habitability inspection services, drawing development, and comprehensive engineering support for aircraft carriers (CVN-70, CVN-72, CVN-73), landing ship dock (LSD) platforms, and yard repair barge (YRBM) vessels. A $2.1 million Coast Guard delivery order awarded March 13, 2025, covers engineering and technical support for vessel design plan review activities to ensure commercial vessel compliance with federal standards, performed in Washington, D.C., through March 2030 under a total small business set-aside. Work is performed across multiple locations including Alexandria, Virginia; Bremerton, Washington (Puget Sound Naval Shipyard and Intermediate Maintenance Facility); Portsmouth, Virginia; and overseas sites including Japan; personnel on Army and classified naval work must hold SECRET clearances, and cybersecurity incident reporting requirements apply.

Activity has remained modest but steady. The vendor recorded six awards in 2022, four in 2023, nine in 2024, eleven in 2025, and four through mid-2026. Only three awards carrying combined potential value of $1.3 million reach ultimate completion within the next twenty-four months, presenting minimal near-term recompete exposure. Tridentis operates almost entirely as a prime contractor; sub-award activity totals only two records across the source data window, with work as a subcontractor to Sayres and Associates LLC on program management and engineering for ship construction and to CACI, Inc. Federal on combat systems alteration and installation support.

GSA Schedule labor categories center on naval architecture and marine engineering roles spanning junior through senior levels and project management, with hourly rates from $73.00 per hour (Junior Naval Architect, bachelor's degree, no experience required) to $222.23 per hour (Project Manager, bachelor's degree, twelve years' experience). No security-cleared positions are offered on the Schedule. Service Contract Inventory data shows limited SCI-reportable activity: $1.2 million in invoiced revenue across FY2023–FY2025 on prime contracts, with staffing at 1.9 FTEs in FY2023 and FY2025 and 9.4 FTEs in FY2025 across prime and sub records. Government-paid rates on SCI prime contracts average $94.69 per hour across the tenth, median, and ninety-fifth percentiles, consistent with entry-level and mid-career naval architect hourly rates on the GSA Schedule.
