About Palmer Johnson Power Systems LLC
Palmer Johnson Power Systems LLC, doing business as Palmer Johnson Distributors, is a for-profit limited liability company based in Sun Prairie, Wisconsin, that supplies and distributes marine propulsion components, heavy-duty transmission and axle parts, and industrial equipment to defense and civilian federal agencies entirely as a prime contractor on small purchase orders and delivery orders. The vendor operates across 730 federal awards with no subcontract footprint; it competes under both full-and-open and total small business set-aside designations, with set-asides appearing in roughly 30% of recent named awards.
Palmer Johnson's customer concentration is fragmented across defense logistics and maritime operations. The top five customers by award count account for 61% of all awards: Defense Logistics Agency Land and Maritime (252 awards, $1.9 million combined potential value), Defense Logistics Agency Aviation (59 awards, $188 thousand), Department of Homeland Security US Coast Guard (51 awards, $1.5 million), Defense Logistics Agency Troop Support Hardware (48 awards, $133 thousand), and Department of the Navy Military Sealift Command (33 awards, $1.7 million). The potential-value ranking shifts slightly toward naval and maritime customers; DLA Land and Maritime, Naval Sea Systems Command, and the Coast Guard anchor most of the dollars across the portfolio. Palmer Johnson sits on the Federal Supply Schedule GS07F0213M with 155 task orders generating $6.4 million in combined potential value, plus three smaller indefinite-delivery contracts with the Coast Guard and the Military Sealift Command.
The vendor's capability portfolio centers on authorized distribution and repair services for marine equipment: clutch and coupling assemblies (Eaton and Danfoss branded components), flexible coupling shafts, brake and power-transmission parts for naval vessels, generator sets, and heavy-duty transmission and axle overhaul services for defense and civilian marine platforms. Recent representative awards include a $56.7 million firm fixed-price purchase order from the Military Sealift Command in April 2025 for butt-end tubes for the USNS Patuxent (a no-set-aside restricted procurement with The Rowland Co as the only other authorized Danfoss distributor), a $44.9 million total small business set-aside delivery order from the Coast Guard in March 2025 for linear actuating cylinders supporting Hamilton Jet outboard propelling units, a $60.5 million total small business set-aside purchase order from the Army Corps of Engineers in February 2024 for Whirley Crane torque-converter repair, and a $25.3 million firm fixed-price purchase order from the Coast Guard in February 2026 for clutch assembly rebuild kits manufactured by Eaton. Activity has declined from eight awards in 2022 to one to four awards annually since 2023; combined potential value sits at $22.5 million across all 730 awards, with $14.9 million obligated to date.
