Aquarian Systems LLC

Aquarian Systems LLC, a Maryland-based limited liability partnership, provides federal IT service delivery as a 100% prime contractor on GSA Schedule task orders, competing on full-and-open basis without set-aside designations. The vendor specializes in communications security operations support, COMSEC system modernization, and government IT infrastructure sustainment, with particular depth in classified communications environments and legacy system migration.

Aquarian operates exclusively as a prime; across ten awards in the source dataset, the vendor has placed zero subcontracted work and builds its own delivery teams. The vendor holds seats on the GSA Multiple Award Schedule (8 task orders, $42 million combined potential value) and operates with minimal customer diversity — 90% of recent awards fund two civilian agencies: the Department of State Bureau of Information Resource Management (2 awards, $34.9 million combined potential value) and the Department of Homeland Security Office of the Chief Information Officer (4 awards, $7 million combined potential value), with smaller exposure to GSA Federal Acquisition Service and the Department of the Air Force. The two highest-value customers rank differently by volume versus dollars; State anchors the dollar position despite fewer awards, while DHS OCIO places more frequent but lower-value task orders.

Recent representative work includes a $2.76 million time-and-materials delivery order from DHS OCIO (awarded September 2026, running through September 2029) for COMSEC Central Office of Record support, requiring personnel technically proficient in the Keystone CMCS software baseline and DHS communications security operations, performed at Chantilly, Virginia. Preceding that work, Aquarian delivered a $807,354 interim task order (September 2025) to finalize development, testing, accreditation, and production deployment of DHS's modernized COMSEC system. These awards sit on the GSA MAS vehicle and reflect the vendor's core capability: managing and modernizing classified communications infrastructure and the personnel who operate it.

Aquarian's activity profile shows sparse but long engagement. The vendor holds ten prime awards dating to 2002, with obligated dollars of $35.1 million against $64.8 million in combined potential value (54% obligation rate). Recent velocity is low — one award in 2025 and one in 2026 — following a two-year gap; the vendor's prior active period ran 2021–2022. On SCI-reportable federal service contracts, invoiced revenue ran $3.1 million across 10.1 FTEs in FY2022, dropped to zero in FY2023, then recovered to $5.9 million (21.6 FTEs) in FY2024 and $6.5 million (19.9 FTEs) in FY2025 — consistent with the gap in task-order activity. Government-paid median hourly rates on SCI records sat around $133.83/hr, with senior labor pricing through $148.54/hr. GSA Schedule labor rates span $102–$208 per hour across eight categories, with security-clearance requirements present across all listed roles and experience bands ranging from two to ten years. The vendor's workforce skews toward operations and technical support analyst positions, systems engineers, and senior engineering management, grounded in bachelor's-degree requirements.

The company designs, develops and implements customized software systems to support full life-cycle applications; converts legacy programs to client-server platforms; provides migration services to new systems; and modifies and enhances existing systems.
