SEACORP

What SEACORP does

SEACORP LLC is a privately held, Rhode Island-based defense contractor founded in 1981 that delivers full-spectrum engineering services and integrated hardware for submarine and undersea warfare electronic systems used by the U.S. Navy and Allied Navies. The company's product surface spans six capability areas: Combat Systems (including AN/BYG-1 Common Infrastructure Services/Common Computing Environment and SWFTS-related work), Electronic Warfare (EMWMS, Code 34 EW, Next Generation EW HMI), Training & Simulation (SUBTM, Weapons Analysis Facility HWIL), Platform & Payload Integration (PWLS, SAFECAP, Modular Launch Canister Technology), in-house Manufacturing & Production at Middletown, RI and Groton, CT facilities, and Cybersecurity (CMMC Level 2 architecture). SEACORP is the second-largest contractor to the Naval Undersea Warfare Center in Newport, RI, and supports Virginia-class, Columbia-class, and SSN(X) submarine programs through dedicated NUWCDIVNPT, NAVSEA, and ONR contracts.

The firm generates revenue exclusively through U.S. government contracting vehicles (SeaPort-NxG, OASIS+, IDIQ-MACs, SBIR, OTA consortiums), with pricing determined via competitive bidding and sole-source awards for accredited submarine work. Recent contract ceiling value exceeds $200M (USW Strike $90M, CIS/CCE $72M, EMWMS $79M, SUBTM $41.9M, Code 34 $40.9M, plus several smaller awards), and the company employs 600-650 personnel across Rhode Island, Connecticut, Virginia, California, Hawaii, Washington, Florida, Georgia, and Australia. Following the March 2021 acquisition by Roy Kapani through KAPCO Defense, LLC and the December 2021 bolt-on of Analysis, Design & Diagnostics (AD&D) for acoustic capabilities, SEACORP's go-to-market is enterprise field sales into Navy program offices via direct contract capture and teaming arrangements.

SEACORP holds CMMC Level 2, ISO 9001:2015, CMMI V2.0 Maturity Level 3, and NAVSEA 09MP AIT approval, which collectively restrict the qualified vendor pool for its core programs. The company was selected as a finalist for the 2025 PBN Fastest Growing Companies Award ($50M+ category), marking its fourth consecutive year of recognition, and management has publicly stated the company is rapidly approaching and has continued past the $100M annual revenue milestone.
