Grid Defence Systems LIMITED

Grid Defence Systems LIMITED, a United Kingdom-based manufacturer of ruggedized military electronics and computers, supplies specialized components and equipment to the U.S. Department of Defense as a prime contractor (75% of recent awards) and as a subcontractor to defense primes. The company is an international limited liability company with no SBA certifications and operates outside the small-business set-aside environment — all prime awards to Grid Defence are full-and-open sole-source procurements based on the company's status as the incumbent qualified supplier for configuration-controlled components.

Grid Defence's federal customer base concentrates entirely within the Department of Defense. The Department of the Navy's Naval Air Systems Command Naval Air Warfare Center accounts for four awards totaling $262 thousand in combined potential value, and the Department of the Air Force Materiel Command (split across the Air Force Sustainment Center with three awards at $262 thousand and the Ogden Air Logistics Complex with two awards at $101 thousand) accounts for five awards. The Department of the Army carries two awards. All twelve awards in the source data are split 75% prime and 25% sub, with dollar concentration matching award count — Navy and Air Force drive both volume and value across the portfolio.

Grid Defence operates on a single IDC, Indefinite Delivery Contract FA823221D0004 (Air Force), with one recorded task order. Recent prime work centers on spare components for Air Force systems: a $91,065 November 2025 firm-fixed-price purchase order from the Air Force Sustainment Center for GMLTS controllers and hard-drive spares (completing August 2026), a $28,335 February 2023 Naval Air Warfare Center purchase order for laptops (completed December 2023), a $52,440 October 2022 Naval Air Warfare Center purchase order for GM-LTS controllers (completed April 2023), a $76,600 September 2022 Naval Air Warfare Center purchase order for navigation test kits (completed January 2023), and a $104,880 May 2022 Naval Air Warfare Center purchase order for GRiDCASE 1590 rugged laptops and hard-drive spares (completed November 2022). All sole-source awards cite Grid Defence as the configuration-controlled incumbent supplier for the GMLTS system and related Air Force equipment with no approved alternate sources.

In its subcontractor capacity, Grid Defence supplies rugged tablets and transport cases to Bell Textron on the Future Vertical Lift FLRAA (Army tactical assault helicopter) pre-ACAT program and provides F-16 support equipment boresight computer kits to BAE Systems Information and Electronic Systems Integration. Activity has been episodic — one award in 2021, three in 2022, one in 2023, one in 2024, and three in 2025 — with modest scale (combined potential value of $625 thousand across twelve awards, though $3 million has been obligated). One award (the November 2025 GMLTS purchase order at $91 thousand) reaches ultimate completion within the next twenty-four months and faces potential recompete exposure. Grid Defence's portfolio is dominated by Electronic Computer Manufacturing and Aircraft Manufacturing NAICS categories, reflecting its core business in ruggedized military computers, laptops, tablets, and associated spares and support equipment.
