Rantec Power Systems Inc.

Rantec Power Systems Inc., a small-business manufacturer of specialized power supplies, DC-DC converters, and circuit card assemblies for military and aerospace applications, operates as a subsidiary of RPS Holdings, Inc. and competes predominantly in full-and-open federal procurement with no set-aside designation recurring across most of its prime footprint — though Total Small Business set-asides appear on roughly 10% of awards. The company is based in Baywood-Los Osos, California, and manufactures source-controlled components under firm fixed-price purchase orders and definitive contracts.

Rantec's customer concentration is heavily weighted toward Navy and Army logistics and sustainment functions. The top five customer agencies by potential value account for 84% of combined potential value, led by the Department of the Navy Naval Supply Systems Command ($23.7 million across 118 awards) and the Department of the Army Materiel Command Aviation and Missile Life Cycle Management Command ($13.5 million across 31 awards), followed by Defense Logistics Agency Land and Maritime ($12.7 million across 165 awards), Air Force Sustainment Center ($10.8 million across 12 awards), and Army Materiel Command Detroit Arsenal ($9.5 million across 5 awards). The Naval Supply Systems Command dominates both award count and dollar share, reflecting sustained reliance on Rantec for power supply components across Navy platforms. Award count and potential value diverge slightly — DLA Land and Maritime places the most individual purchase orders (165) but carries the third-largest dollar total, indicating a high-volume, lower-average-order-value relationship, while Army Aviation and Missile LCM concentrates larger platform-level contracts into fewer awards.

Rantec holds positions on five named parent vehicles: single-award indefinite delivery contracts with DLA Land and Maritime (SPRBL115D0017, 8 task orders), Naval Supply Systems Command (SPRWA121D0010, 6 task orders, $8.9 million combined potential value), and Air Force Sustainment Center (valued near $2 million with recurring delivery orders for ALR-56M power supplies for F-16C and C-130J aircraft), plus basic ordering agreements with Naval Supply Systems Command (N0010492GA080, 5 task orders) and Air Force Sustainment Center (FA862021G4028, 3 task orders). Recent representative prime work includes a $3.978 million delivery order for production of ALR-56M PS1 and PS2 power supplies for the Air Force Sustainment Center (February 2025), a $2.25 million Naval Supply Systems Command definitive contract for power systems (October 2025), a $1.776 million DLA Land and Maritime total small business definitive contract for power supply equipment (May 2026), and a $1.996 million Army Aviation and Missile Command definitive contract for power supplies (January 2026). A single-award IDC with DLA Land and Maritime for pulse transformers (NSN 5950011228898) was awarded June 30, 2026, with a $350,000 ceiling and completion through June 30, 2027.

Prime awards account for 90% of the total footprint (544 of 603 awards), with sub work (10%, 59 awards) concentrated on Raytheon Company across Patriot missile system production and support, Advanced Technology Support Program (ATSP) microelectronic capability work, and foreign military sales. Rantec also subcontracts DC-DC converter and electronics components to BAE Systems Information and Electronic Systems Integration Inc., General Dynamics Land Systems Inc., Northrop Grumman Systems Corp, General Atomics, Lockheed Martin Corporation, and Lockheed Martin Sippican Inc., primarily for power supply and converter work on airframe integration, munitions guidance, and carrier platform systems.

Activity has grown steadily — 14 awards in 2022 to 34 in 2025 — with 11 awards in 2026 year to date. Ten awards with ultimate completion dates in the next twenty-four months carry combined potential value of $12.7 million and face recompete. The source material indicates obligated dollars ($144.6 million) exceed combined potential value ($83.9 million) by 72%, reflecting cumulative invoicing and modifications across the multi-year portfolio. NAICS concentration clusters in electrical transformer and specialty component manufacturing (62 awards in Power, Distribution, and Specialty Transformer Manufacturing; 61 in All Other Miscellaneous Electrical Equipment and Component Manufacturing; 57-58 in Motor/Generator and Capacitor/Inductor categories). PSC-level concentration shows Converters, Electrical, Nonrotating as the dominant commodity code (242 awards), followed by Coils and Transformers (111 awards) and Electrical and Electronic Assemblies (46 awards). The vendor has worked with 29 distinct federal customer agencies across four decades of contracting history dating to 1989.
