Sedna Digital Solutions, LLC

Sedna Digital Solutions, LLC, a for-profit limited liability company headquartered in Manassas, Virginia, specializes in engineering design, rapid prototype development, and specialized component manufacturing and repair services for naval platforms and missile defense systems, operating as a prime contractor on 69% of recent awards and as a subcontractor to defense primes on the remainder. The vendor competes on full-and-open basis across all recent work with no set-aside designations except for one total small business set-aside award.

Sedna's customer concentration is extreme and single-customer dependent. The Department of the Navy Naval Sea Systems Command (NAVSEA) accounts for 27 of 44 awards and $1.51 billion of $1.56 billion in combined potential value — representing 98% of dollars. This concentration reflects Sedna's core mission: engineering design and development for submarine modernization and acoustic system upgrades across Los Angeles, Virginia, and Columbia-class submarines, along with component manufacturing and repair services through Naval Supply Systems Command (NAVSUP). Representative prime work includes a $223.6 million cost-plus-incentive definitive contract awarded December 2022 for FY23 engineering design development of Total Ship Monitoring Systems supporting Virginia-class modernization (performance through December 2030); a $112.1 million cost-plus-fixed-fee engineering design development contract awarded March 2023 for submarine decommissioning and reactivation of electronic equipment (DEOB-REOB) and Total Ship Monitoring Systems upgrades (performance through March 2028); and smaller NAVSUP purchase orders for towed array integrated electrical enclosure chassis, circuit card assemblies, and repair services for towed array hardware ($259 thousand, $450 thousand, and $114 thousand respectively, awarded January 2026, September 2025, and September 2023). Sedna also holds a $151 billion multiple-award IDIQ with the Missile Defense Agency under the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) vehicle, awarded December 2025 with a ten-year performance period through December 2035; a single $500 initial task order has been placed against SHIELD. The vendor maintains two active single-award indefinite delivery contracts with NAVSEA: a $48.9 million rapid prototype development services contract (October 2021–September 2026) and a now-expired or completed IDC.

Activity has accelerated recently, rising from two awards in 2022 to eleven in 2024, with a moderation to six awards in 2025 and one in early 2026. Three awards with combined potential value $112.8 million are scheduled for ultimate completion within the next twenty-four months, creating recompete exposure centered on NAVSEA engineering design and development work. Sedna's top NAICS concentrations are search, detection, navigation, guidance, aeronautical and nautical system and instrument manufacturing (20 awards) and engineering services (9 awards), with electrical hardware and supplies and underwater sound equipment as leading PSC categories.

In its subcontractor role, Sedna delivers engineering design, integration support, and maintenance labor to Lockheed Martin on multiple tranches of submarine modernization work (ten sub awards since December 2023, including integration labor for ICP builds T-22, T-23, T-99 and JAOS support), to General Dynamics on Total Ship Monitoring Systems production (one award May 2025), and to General Dynamics Information Technology on signature measurement and control support services (one award November 2024). Sedna's federal award footprint is Navy-centered and narrow: nearly all dollars flow from NAVSEA's submarine platform modernization portfolio, with material near-term recompete risk concentrated in three large engineering design and development awards completing in the next twenty-four months.
