About KMS Solutions, LLC
KMS Solutions, LLC, a minority-owned, small disadvantaged business and subsidiary of Subsystem Technologies Inc., delivers naval engineering, program management, submarine maintenance, cybersecurity, and integrated logistics support services to the Department of the Navy as a prime contractor under the Seaport-NXG vehicle and other Navy-managed IDIQs, with no set-aside restrictions on most prime awards despite qualifying for total small business set-asides.
KMS Solutions is a Subcontinent Asian American-owned, self-certified small disadvantaged business headquartered in Alexandria, Virginia. The company operates as a prime contractor on 69 percent of its 67 recent awards (46 primes versus 21 subs) and competes predominantly in full-and-open, unrestricted procurements rather than under small-business set-asides, though it holds positions on multiple set-aside vehicles including OASIS+ Total Small Business and participates in the Undersea Weapons and Undersea Defensive (UW/UD) Family of Systems contract. Primary NAICS concentration runs to engineering services (49 awards), professional and management development training (7 awards), and research and development in physical and engineering sciences (3 awards).
Naval Sea Systems Command (NAVSEA) dominates KMS Solutions' customer footprint, accounting for 49 of 67 awards and $10.91 billion of $10.93 billion in combined potential value (99.8 percent concentration). The remainder distributes across the Department of State Foreign Service Institute ($71 thousand, 5 awards), GSA Federal Acquisition Service ($3.4 million, 4 awards), the Office of the Secretary of Defense ($8.7 million, 4 awards), and the Missile Defense Agency ($500, 2 awards). This concentration reflects KMS Solutions' specialization in submarine and undersea warfare systems rather than diversification across civilian or defense agencies.
Seaport-NXG anchors the vehicle portfolio, with 33 task orders and $562 million in combined potential value, followed by SeaPort-e (13 task orders, $108.8 million). KMS Solutions also holds seats on OASIS+ Unrestricted and OASIS+ Total Small Business (both awarded December 2024 with placeholder ceilings), the SHIELD multi-domain defense IDIQ (awarded December 29, 2025, $151 billion ceiling), and the Undersea Weapons/Undersea Defensive Family of Systems MAC ($245.9 million ceiling). Representative Seaport-NXG awards include a $177.5 million delivery order (September 10, 2025) for in-service submarine contractor support spanning program management, administrative, financial, technical, and integrated logistics services across six program offices (PMS 390, 392, 394, 396, 07L, 07Q); a $60.3 million order (July 21, 2025) for submarine maintenance engineering, planning, and procurement (SUBMEPP) support; a $30.7 million order (January 14, 2026) for submarine program management and engineering technical support to NSWCPD Code 24; and an $18.7 million cybersecurity order (November 21, 2023) covering assessment and authorization packages, test and evaluation environment maintenance, and information systems security support to Naval Undersea Warfare Center Division Newport Code 25.
Activity has accelerated sharply in recent years, rising from 3 awards in 2022 and 2023 to 7 in 2024 and 21 in 2025, reflecting NAVSEA's sustained demand for submarine and undersea systems engineering. Six awards (combined potential value $234.5 million) reach ultimate completion within the next twenty-four months, presenting recompete exposure concentrated on Seaport-NXG platforms.
Across SCI-reportable prime service contracts, KMS Solutions invoiced $92 million over FY2022–FY2024, growing from $22.3 million (115 FTEs) in FY2022 to $40.7 million (190 FTEs) in FY2024. The vendor reports 33 percent average sub-hours share on its prime SCI contracts and engages roughly 30 named subcontractors, indicating reliance on subcontractor delivery rather than an entirely in-house workforce. Government-paid hourly rates on prime SCI work run with a median of $107.92/hr, spanning 10th percentile at $86.20/hr to 90th percentile at $140.56/hr. Named subcontractor partners appearing across SCI records include Serco Inc., Synchron LLC, and Epsilon Systems Solutions, though Serco and other subs also appear as primes on parallel NAVSEA work. KMS Solutions subcontracts primarily to Seacorp, LLC (17 visible sub-awards covering Virginia, Columbia, and SSN(X) class submarine engineering and systems engineering since March 2024), and performs named engineering and technical services for Serco Inc. and Synchron LLC on submarine combat systems and platform engineering work.
