About the company
Western Diesel Services, Inc., doing business as CK Power, manufactures and distributes power generation equipment and engine components to the Department of Defense, Department of Veterans Affairs, and related federal agencies as a prime contractor. The company is a small business based in Olivette, Missouri, and competes predominantly under full-and-open and Total Small Business set-aside designations across a highly fragmented portfolio of purchase orders and delivery orders rather than large complex vehicles.
CK Power's federal work centers on supplying discrete mechanical and electrical engine components — fluid filters, electric starter engines, fuel pumps, gaskets, seals, injector assemblies, and related power generation parts — for military equipment maintenance and logistics operations. The company operates from its Olivette facility and performs work domestically and at overseas Defense Logistics Agency depots and Department of Veterans Affairs medical centers. Recent representative work includes a $33,115 purchase order from the National Oceanic and Atmospheric Administration (June 2026) for a hurricane program generator supporting Hurricane Radar 2; a $50,000 emergency automatic transfer switch repair delivery order from the Veterans Integrated Service Network 15 (March 2026); a $71,850 fuel pump cam actuator delivery order under a Defense Logistics Agency Total Small Business set-aside (November 2025); and a $93,002.93 annual generator maintenance and load bank testing delivery order from VISN 15 (January 2026). The company also holds a substantial $986,137 indefinite delivery contract with VISN 15 running through November 2029 for generator maintenance, load bank testing, and electrical services at VA medical facilities.
Customer concentration is extreme and heavily weighted toward the Defense Logistics Agency Land and Maritime, which accounts for 3,646 awards (66% of the total portfolio) and $70.8 million (66% of combined potential value) across CK Power's 5,505 awards since 1982. The top five funding agencies cover 98% of recent awards. The Defense Logistics Agency Troop Support Hardware places 1,058 awards valued at $234 thousand; Aviation places 563 awards valued at $1.3 million; and the Department of Veterans Affairs VISN 15 places 20 awards valued at $1.9 million. Two outlier Army awards (Joint Munitions Command, 2024) carry $24.9 million combined potential value but appear isolated from the vendor's primary business.
CK Power holds ten active indefinite delivery contracts with the Defense Logistics Agency Land and Maritime, each valued at $250,000 to $350,000 and running one-year terms. Eight carry Total Small Business set-aside designations; two carry no set-aside. These vehicles procure fluid filters, electric starter engines, fuel pump cam actuators, injector assemblies, and control assemblies, with delivery requirements typically between 28 and 105 days. The company draws task orders across these vehicles continuously; recent high-volume vehicles include IDC SPM7LX13D0059 (41 task orders, $501 thousand) and IDC SPE7LX14D0014 (16 task orders, $162 thousand). The company also holds one indefinite delivery contract with VISN 15 valued at $986,137 through November 2029.
Activity has declined from 356 awards in 2022 to 35 in 2026 (year-to-date as of June 2026), reflecting a sharp drop in ordering volume over the past four years. Four awards with completion dates in the next twenty-four months carry combined potential value of only $215 thousand, signaling low near-term recompete exposure. The vendor obligated $24.2 million against $107.2 million in combined potential value across the portfolio (23% obligation rate), suggesting a large backlog of unexercised delivery order capacity.
CK Power operates as a prime contractor on all identified federal awards with no named subcontractors. The source identifies one subsidiary, C-K Power Products Corp, also a for-profit organization. The company's award portfolio spans 35 customer agencies but is dominated by a single customer relationship — the Defense Logistics Agency Land and Maritime — which represents both the primary revenue stream and the dominant vehicle structure for the business. The vendor does not hold positions on government-wide acquisition contracts, multiple-award schedules, or agency-wide IDIQs; all work flows through direct awards from the Defense Logistics Agency or targeted single-award indefinite delivery contracts with specific agencies.
