Rantec Power Systems Inc.

Rantec Power Systems Inc., doing business as Rantec Power Systems, manufactures specialized power supplies, DC-DC converters, circuit card assemblies, and related electronic components for military and aerospace applications as a prime contractor (91% of awards) and subcontractor to major defense primes. The company operates as a subsidiary of RPS Holdings, Inc. and competes predominantly on full-and-open federal procurements without set-aside designations, though it qualifies as a small business and has won a small number of Total Small Business set-aside awards.

Rantec is headquartered in Baywood-Los Osos, California, and operates as a for-profit Subchapter S corporation. The company's capability footprint centers on engineered power conversion equipment: power supplies for avionics systems including the Advanced Radar Warning System (ALR-56M) on F-16C and C-130J aircraft, AC-DC and DC-DC converters for missile systems including the Patriot weapon system, circuit card assemblies for defense platforms, and transformers and reactors supporting military electronics. Representative prime work includes a $3.98 million delivery order from the Air Force Sustainment Center (February 2025) for ALR-56M PS1 and PS2 power supply production, a $2.25 million Naval Supply Systems Command power supply contract (October 2025), a $1.995 million single-award Indefinite Delivery Contract with the Air Force Sustainment Center for Advanced Radar Warning System power supplies (running through September 2026 with six delivery orders executed totaling over $8.8 million), a $1.19 million Aviation and Missile Command contract for Patriot missile spare power supplies (January 2025), and a $1.35 million Naval Supply Systems Command power supply award (August 2025).

Customer concentration sits heavily with defense logistics and Navy supply agencies. The top five funding entities account for 83% of combined potential value: the Department of the Navy Naval Supply Systems Command leads with 116 awards ($23.2 million), followed by the Department of the Army Materiel Command Aviation and Missile Life Cycle Management Command (31 awards, $13.5 million), the Department of the Air Force Materiel Command Air Force Sustainment Center (12 awards, $10.8 million), the Defense Logistics Agency Land and Maritime (162 awards, $10.6 million), and the Department of the Army Materiel Command Contracting Command Detroit Arsenal (5 awards, $9.5 million). Rantec has worked with 29 distinct federal customer agencies spanning Navy, Army, Air Force, and Defense Logistics Agency components. Award volume has grown sharply — from 14 in 2022 to 33 in 2025 — with seven awards (combined potential value $11.8 million) reaching ultimate completion inside the next twenty-four months and therefore facing recompete.

The vendor holds or participates in several indefinite delivery vehicles. Top parent vehicles include an unnamed Indefinite Delivery Contract (SPRBL115D0017) with six task orders, Indefinite Delivery Contract SPRWA121D0010 with six task orders ($8.9 million combined potential value), Basic Ordering Agreement N0010492GA080 with five task orders, Indefinite Delivery Contract SPRWA125D0004 with five task orders, and the Advanced Technology Support Program IV with three task orders. The single-award Air Force Sustainment Center IDC for power supplies serves as the highest-value recurring vehicle, generating substantial delivery order activity.

In its subcontractor role, Rantec supplies specialized power conversion equipment to defense primes including Raytheon Company (dominant partnership, with sub awards for Patriot missile spare parts, counter-unmanned aircraft systems, Silent Knight radar systems, and foreign military sales packages), General Dynamics Land Systems, Northrop Grumman Systems, Lockheed Martin Corporation (warhead upgrade kits, aircraft-fixed wing components), BAE Systems Information and Electronic Systems Integration, General Atomics (CVN 79 EMALS long lead material), and Atlantic Diving Supply. The subcontract work centers on DC-DC converters, AC-DC power supplies, and frequency converters for aircraft, missiles, and radar systems.

NAICS concentration reflects manufacturing specialization: Power, Distribution, and Specialty Transformer Manufacturing (61 awards), Motor and Generator Manufacturing (58 awards), All Other Miscellaneous Electrical Equipment and Component Manufacturing (58 awards), and related categories. Product Service Code concentration is similarly narrow: 239 awards for Converters, Electrical, Nonrotating (PSC 59-U), 109 awards for Coils and Transformers (PSC 59-L), and 46 awards for Electrical and Electronic Assemblies, Boards, Cards, and Associated Hardware (PSC 59-P). The vendor's portfolio shows cumulative dollars obligated at $138.6 million against a combined potential value of $81.3 million across all 595 awards in the source, indicating either significant contract modifications or invoice activity exceeding initial ceiling values on recurring vehicle awards. Rantec's recent activity trajectory and single-award Air Force IDC positioning place it as a specialized supplier entrenched in legacy avionics and missile power supply supply chains for multiple defense agencies.
