L3Harris Maritime Services Inc.

L3Harris Maritime Services Inc., a division of L3Harris Technologies Inc., supplies specialized maritime electronic components, cable assemblies, and repair services to the U.S. Navy as a prime contractor (75% of recent awards) and as a subcontractor to major shipbuilders including BAE Systems, Huntington Ingalls, and Electric Boat Corporation. The company competes in full and open competition without set-aside designation across its federal footprint.

L3Harris Maritime Services is headquartered in Norfolk, Virginia, a major naval hub, and operates as a manufacturer of goods and provider of engineering and repair services. Primary NAICS concentration spans Ship Building and Repairing (271 awards), Engineering Services (119 awards), and Electronic Component Manufacturing (43 awards). The vendor's capability portfolio centers on copper sonar cable assemblies for submarine platforms, specialized cable assemblies (power, fiber optic, and hybrid variants), circuit card assembly repair, pressure transducers, electrical control panels, rudder angle transmitters, and engine room control system maintenance across naval vessel classes. Representative prime work includes a $3.67 billion delivery order for keel cables supporting SSN 774 submarine programs, a $2.12 million TANO Phase III RTU replacement delivery order for Military Sealift Command, a $1.08 million build-to-print copper sonar cable assembly order for NAVSEA, and recurring circuit card assembly repairs valued at $300,000 to $700,000 per order for Naval Supply Systems Command.

Customer concentration is overwhelming. Naval Sea Systems Command (NAVSEA) anchors 377 awards (49% of portfolio) with $14.37 billion combined potential value—by far the largest customer. Naval Supply Systems Command follows with 109 awards at $99.5 million, Military Sealift Command with 59 awards at $101.6 million, and Defense Logistics Agency Aviation with 56 awards at $7.5 million. These top five agencies account for 87% of recent awards. The Army Materiel Command's TACOM Life Cycle Management Command holds a single but outsized award: a $186 million multiple-award contract for Army Watercraft Sustainment Maintenance providing pier-side maintenance services for Army vessels worldwide.

L3Harris Maritime Services holds four principal indefinite delivery vehicles. A $29.4 million single-award NAVSEA IDV covers cable assemblies (copper, fiber, and hybrid) supporting submarine programs through September 2029, with 74 task orders totaling $82.5 million in combined potential value. A $31.3 million single-award NAVSEA IDV for outboard cables and technical services runs through December 2027. A $49 million multiple-award IDV with Military Sealift Command (awarded February 2026) covers engine room control systems maintenance and repair on USNS Supply and T-AO class vessels through August 2031. Two smaller DLA Aviation single-award IDVs—one for $712,566 covering power cable assemblies through October 2029 and another for $1.56 million for specialized cable assemblies through September 2029—round out the vehicle portfolio.

Activity has grown significantly over five years: 41 awards in 2022, accelerating to 145 in 2024 before moderating to 126 in 2025 and 18 through April 2026 (partial-year data). Thirty-eight awards reach completion within the next twenty-four months with combined potential value of $23.6 million, representing recompete exposure primarily in cable assembly and circuit card repair categories.

As a subcontractor, L3Harris Maritime Services delivers specialized cable assemblies and electronic components under BAE Systems Jacksonville Ship Repair and BAE Systems Maritime Solutions (eight awards spanning USS Ramage, USS The Sullivans, and CNO availability work), Huntington Ingalls (fourteen awards on DDG 51 class construction and carrier refueling and overhaul planning), Vigor Marine (seven awards on destroyer and guidance system transducers), Electric Boat Corporation (four awards on submarine ship control backfit and secondary propulsion), National Steel and Shipbuilding (three awards on DDG and cruiser repair planning), Eastern Shipbuilding (three awards on Offshore Patrol Cutter support), Lockheed Martin (one cable assembly and test labor award), and Metro Machine (two awards on destroyer and carrier availability). These sub relationships reveal L3Harris Maritime Services' strategic position as a specialized supplier of critical electronic and cable systems to the Navy's primary integrators and shipyards.

Service Contract Inventory reporting shows minimal captured activity: zero SCI-reportable invoiced revenue across FY2022–FY2024, with FTE trajectory of 45.4 in FY2022 declining to zero in FY2023 and recovering to 24.5 FTEs in FY2024. This sparse SCI footprint indicates the vendor's work—primarily goods manufacturing and delivery orders under existing IDVs—falls outside the $150,000 SCI reporting threshold for service contracts, or is classified. SCI does not capture the vendor's actual federal revenue or workforce scale; the award portfolio and obligated dollars provide more decision-relevant signals of commercial activity.

L3Harris Maritime Services operates as a division of L3Harris Technologies Inc., a major aerospace and defense prime contractor. The parent company's technological infrastructure and established Navy relationships underpin the division's competitive position on specialized maritime electronic systems. The vendor's strategic assets include sole-source or limited-competition positioning on submarine and surface-vessel cable assembly work, established footprint with NAVSEA and Military Sealift Command, and tight integration with Navy shipyard and shipbuilder supply chains. The $186 million Army Watercraft contract and smaller Coast Guard awards (interface units, loudspeakers, modification kits, microphone elements) signal diversification beyond Navy core business, though Navy exposure remains dominant by both award count and dollar value.
