About the company
Defense Systems And Services LLC, a Yorktown, Virginia-based SBA Veteran-Owned Small Business (VOSB) certified through April 2028, operates exclusively as a subcontractor delivering engineering and human resources services to the Department of the Navy Naval Air Systems Command (NAVAIR). The vendor holds no prime contracts or IDVs and does not compete in full-and-open procurements; all eight tracked awards are subcontracts under Northrop Grumman Systems Corporation on the NAVAIR Strategic Sourcing for CMMARS vehicle (N61340-19-D-1014). The vendor is a Subchapter S corporation structured as a for-profit organization.
Defense Systems & Services functions as a pure feeder subcontractor to Northrop Grumman on NAVAIR programs. All work flows through the CMMARS contract, with recent task orders (five in 2025, three in 2023) spanning engineering services, human resources support, and depot-level material provisioning for E-6B aircraft sustainment and repair operations. The vendor has zero prime-award volume and zero prime-vehicle seats; customer concentration is complete — NAVAIR accounts for 100% of tracked awards, and Northrop Grumman is the sole named prime.
Service Contract Inventory reporting captures minimal activity: two SCI records across FY2022–FY2024 (zero as prime, two as named subcontractor), reflecting the vendor's small scale on reportable service contracts. SCI-reported FTE delivery ran 0.4 FTEs in FY2022 and 0.9 FTEs in FY2024, with no prime invoicing. The SCI dataset is a partial view and does not include goods, classified contracts, or non-federal revenue; it signals that Defense Systems & Services operates at a small scale on the visible federal services footprint but does not capture the full magnitude of subcontract work or enterprise revenue.
The vendor's positioning as a 100% subcontractor on a single Northrop Grumman NAVAIR vehicle with no recompete exposure in the next twenty-four months (all awards are modifications and extensions under a standing CMMARS task order) places it outside the prime-contractor competitive set and makes it a feeder supplier for Northrop Grumman-anchored NAVAIR engineering and sustainment work.
