About the company

Seacorp, LLC, doing business as Sea Corp, is a small business systems engineering, software development, and test and evaluation firm based in Middletown, Rhode Island, that serves as a prime contractor (96% of recent awards) on defense and naval engineering programs under full-and-open competition with no recurring set-aside posture. The company manufactures specialized hardware, delivers submarine combat control systems and payload integration technologies, and conducts SBIR Phase III research and development for the Naval Sea Systems Command and the Office of Naval Research, with particular concentration in undersea warfare, communications, and electromagnetic warfare modernization.

Seacorp's federal footprint centers almost entirely on the Department of the Navy. Naval Sea Systems Command dominates the customer base at 830 awards carrying $13.58 billion in combined potential value, representing 97% of the active prime award count. The Office of Naval Research anchors research funding with 10 awards valued at $985.6 million (mostly a single $150 million definitive contract for Electromagnetic Maneuver Warfare Modular Suite design and development). The Defense Contract Management Agency holds 98 awards at $603 million potential value. This concentration reflects Seacorp's specialized technical posture: the company competes almost exclusively within Navy undersea warfare, submarine modernization, and advanced systems integration rather than seeking broad federal civilian exposure.

Seacorp's primary vehicle portfolio sits on Navy-managed IDVs rather than government-wide acquisition contracts. The firm holds positions on five major contract vehicles driving 460 task orders. The largest vehicle by task-order volume is Indefinite Delivery Contract N6660497D1007 with 172 task orders; N6660402D0940 carries 166 task orders and $37.2 million in potential value; N6660412D1068 spans 85 task orders at $29.3 million potential. Seacorp also holds a $29.5 million single-award IDV with NAVSEA for Extensible Markup Language Test Data Analysis Tool engineering services (multiple delivery orders cited in the source) and sits on the Seaport Next Generation (Seaport-NXG) multiple-award contract for submarine platform engineering, modernization, and technical services. Beyond Navy, the company recently acquired seats on GSA's OASIS+ Unrestricted (April 2025) and OASIS+ Total Small Business (December 2024) multiple-award IDIQs, signaling expansion into civilian federal services.

Concrete representative work spans submarine combat systems, payload control system development, and advanced test and evaluation. Seacorp delivered a $70.7 million Seaport-NXG delivery order (August 2025) for development, integration, test and evaluation, modernization, and sustainment of Los Angeles, Ohio, Seawolf, Virginia, Columbia, Vanguard, and Dreadnought class submarine fleets, with subcontractors Mikel Inc. (women-owned small business providing undersea defense engineering) and KMS Solutions, LLC (minority-owned small disadvantaged business delivering submarine maintenance and warfare systems engineering). An $85.7 million Seaport-NXG delivery order (December 2024) addressed Virginia Class, Columbia Class, SSN(X) Class platform and systems engineering with American Systems Corporation, Amentum Services, Inc., Mikel Inc., Marine Acoustics Inc., Cardinal Engineering LLC, and Rite-Solutions Inc. (service-disabled veteran-owned small business) as subcontractors. A $74.9 million definitive contract (May 2024) for Common Infrastructure Services design, development, test, integration, and logistics support involved General Dynamics Mission Systems, Sonalysts Inc., Advanced Systems Supportability Engineering Technologies And Tools, and Lockheed Martin Corporation as subcontractors. On SBIR Phase III, Seacorp holds a $150 million definitive contract (April 2023) for Advanced Technology Development Human Machine Interface research with subcontractors including Parity Intelligence, Systems & Technology Research LLC, Merrimac Industries, Xsoptix LLC (woman-owned small business), Nu Waves LTD (veteran-owned small business), and Amprius Technologies. Delivery orders under that phase address payload control system modification, kill chain software integration, combat control system adaptation, and XML test data analysis tool development, ranging from $70 thousand to $1.2 million per task order.

Activity has grown substantially year over year — 20 awards in 2022 to 65 in 2024 — then declined to 27 in 2025 and only 6 in the first quarter of 2026, reflecting the timing and profile of large annual Navy appropriations. The firm faces recompete exposure: 21 awards carrying $453.3 million in combined potential value complete within the next twenty-four months, including the $85.7 million submarine platform engineering order and multiple XTDAS and payload control system delivery orders under the large Seaport-NXG vehicle.

Seacorp operates as a prime on the vast majority of work; subcontractor engagement is minimal. The vendor holds four definitive contracts and multiple-award IDVs that generate delivery orders under which Seacorp primes and controls scope. Across SCI-reportable service contracts (federal awards above $150,000 threshold), Seacorp recorded $22.9 million in invoiced revenue in FY2023 across 143 FTEs, with hourly rates running a median $76.55/hr and a 90th percentile of $86.63/hr — a mid-tier government services rate posture. The SCI-reported sub-engagement share averages 9% of contractor hours, indicating Seacorp builds and staffs its own delivery teams. As a subcontractor, the company performs narrow technical roles: Seacorp subs to Lockheed Martin on submarine electronic warfare and sonar systems (multiple awards for BLQ-10, RFDU, and combat control system components), to General Dynamics Mission Systems on torpedo tube deployment systems and electronic warfare tactical upgrade, to Rite-Solutions on trainer systems development and engineering support, to CACI on Naval Undersea Warfare Center engineering, and to Northrop Grumman and Leidos on specialized naval systems work. Recent sub awards span imaging systems engineering, communications and electromagnetic warfare support, and tactical naval sensing correction tasks.

The company operates through one named subsidiary: Analysis Design & Diagnostics Inc., a veteran-owned small business, which appears in corporate structure but does not recur prominently in the award data. Seacorp's owner status is listed as a partnership or limited liability partnership without explicit minority, women-owned, or service-disabled veteran ownership stated in the corporate profile, though subcontractor teaming patterns and the subsidiary designation suggest internal diversity or veteran alignment. The firm's manufacturing designation in SAM reflects the breakout boxes, antenna and imaging hardware, and specialized cable assemblies it produces alongside systems engineering services — a capability set that distinguishes it from pure services vendors and aligns with its SBIR Phase III hardware-heavy research contracts.
