Reliable System Services Corp.

Reliable System Services Corp., a minority-owned, Hispanic American-owned subchapter S corporation based in Melbourne, Florida, manufactures specialized electronic systems and communications equipment as a prime contractor to the Department of Defense, with 100% of recent awards held as prime positions and zero subcontract footprint. The vendor operates as a for-profit manufacturer of goods (NAICS 334220 — Radio and Television Broadcasting and Wireless Communications Equipment Manufacturing) and electronics repair specialist (NAICS 811210), competing predominantly in full-and-open procurements with no set-aside designation across most of its portfolio, though individual awards occasionally employ small-business or woman-owned small-business set-asides.

Reliable System Services Corp.'s capability portfolio centers on high-power amplifiers (HPAs), radio amplifiers, tactical communications equipment, inspection and repair services, and systems engineering support for naval programs. Representative work includes a $48.3 thousand purchase order from Naval Sea Systems Command for a linear amplifier supporting the Navy's Unmanned Surface Vehicle Family of Systems program (awarded August 2024), a $33.4 thousand sole-source purchase order from Naval Sea Systems Command for inspection and repair of High Power Amplifiers (awarded July 2025), a $44.2 thousand 100% small-business set-aside purchase order from Air Force Materiel Command for a Legacy IRIG Flight Termination System (awarded July 2025), and a $45.8 thousand pre-repair services award from Naval Sea Systems Command (awarded December 2023). The vendor also holds a $151 billion indefinite delivery/indefinite quantity contract awarded by the Missile Defense Agency in December 2025 (SHIELD — Scalable Homeland Innovative Enterprise Layered Defense), though only a $500 initial delivery order has been issued to date.

Customer concentration is extreme: Naval Sea Systems Command dominates at 46 awards carrying $991.7 million combined potential value (84% of combined potential value across all 153 awards). The Department of the Navy as a whole accounts for 74 awards, with Naval Information Warfare Systems Command ($5.4 million across 3 awards) and Naval Supply Systems Command ($1.1 million across 10 awards) providing secondary Navy volume. The Department of the Air Force holds 44 awards but carries only $44 thousand in combined potential value, reflecting the small, transactional nature of Air Force engagement. GSA Federal Acquisition Service places 14 awards worth $475 thousand. Activity is episodic — four awards in 2020, one in 2021, two in 2023, two in 2024, and five in 2025 — with combined potential value concentrated at $1 billion and obligated dollars at only $57.4 million (6% of potential value), indicating the portfolio carries substantial ceiling value but limited invoiced spend to date. The vendor holds seats on Federal Supply Schedules (GS23F0172K with 15 task orders and GS35F0151J with 3 task orders) and placement on multiple Navy indefinite delivery contracts (N6600109D0030 with 10 task orders and $2.8 million combined potential value; F0865096G0029 with 8 task orders).
