About the company
Neptune Aviation Services, Inc., doing business as Northstar Jet, supplies aircraft maintenance and repair services for federal firefighting aircraft and aviation turbine fuel to federal agencies as a woman-owned small business operating exclusively as a prime contractor from Missoula, Montana.
The company competes exclusively on full-and-open awards without set-aside designation across two customer agencies. Northstar Jet's federal footprint divides sharply between high-volume, low-dollar fuel deliveries and lower-volume, higher-value aircraft maintenance work. The Defense Logistics Agency Energy (DLA Energy) dominates by award count—2,232 task orders representing $11 million in combined potential value—but represents routine aviation turbine fuel supply at commercial airports across eleven western states and territories (Alaska, American Samoa, California, Hawaii, Idaho, Montana, Nevada, Oregon, Utah, Washington, and Wyoming). The National Interagency Fire Center (NIFC) anchors the dollar value with 233 awards totaling $16.2 million in combined potential value, consisting of aircraft maintenance, inspection, repair, parts procurement, and specialized manufacturing work on SD3-60 Sherpa and Cessna 206 aircraft used in federal wildland fire management.
Northstar Jet's core capability is full-spectrum aircraft maintenance and repair—ranging from routine inspections (50-hour, A-check, B-check, C-check, and D-check inspections) through engine overhauls, structural repairs (wing skin repairs, landing gear overhauls, strut re-seals), avionics installation, component replacement, and specialized manufacturing (Sherpa jump seat diaphragms, hydraulic pressure switches, flight data recorder installations). Recent representative work includes a $1.16 million FDR-CVR A-kit installation on nine Sherpa aircraft (awarded December 22, 2025, completion December 30, 2026), a $179.65 thousand Sherpa heated windshield replacement (May 13, 2026), a $146.19 thousand Sherpa 3C check inspection (January 22, 2026), an $86.65 thousand Sherpa flight data recorder overhaul (September 3, 2025), and multiple five-figure engine hot section inspections and detailed aircraft inspections. DLA Energy work consists entirely of aviation turbine fuel (Jet A, Jet A-1, JP-8) supply calls under a single-award IDV (SPE60718D0050) running through March 2029.
The two parent vehicles dominate the portfolio. The DLA Energy IDV (SPE60718D0050) carries 2,084 task orders worth $3.2 million in combined potential value and runs through March 2029. The NIFC IDV (1202SA22T9505) generated 229 task orders valued at $6.1 million combined potential value. A secondary NIFC vehicle (1202SA22RT9505) supports parts procurement and specialized manufacturing, carrying additional aircraft maintenance and component orders. Northstar Jet self-performs all federal work with no subcontractor engagement.
Activity has rebounded sharply in 2026 after flat years 2023–2025. The company placed four awards in 2022 (226 total that year reflect parent-level consolidated data), 57 in 2023, 49 in 2024, 50 in 2025, and 185 in 2026 through September 18. Within the next twenty-four months, eleven awards (combined potential value $1.4 million) reach ultimate completion, creating recompete exposure concentrated among NIFC aircraft maintenance task orders and DLA Energy fuel delivery calls. The parent corporation, Neptune Aviation Services, Inc., is a Subchapter S corporation headquartered in Missoula, Montana, described in source material as operating the largest privately owned fleet of large airtankers in the United States and holding substantial IDV contracts with the U.S. Forest Service and Bureau of Land Management for aerial firefighting operations—context that positions Northstar Jet as the federal maintenance and supply arm of a larger, diversified aviation services enterprise focused on wildland fire management operations across the western region.
