Heatcon Composite Systems, Inc.

Heatcon Composite Systems, Inc., a veteran-owned small business manufacturer based in Tukwila, Washington, supplies composite repair sets, hot bonder controllers, vacuum pumps, cable assemblies, and specialized aerospace maintenance equipment to the Department of Defense as a prime contractor (99% of recent awards). The company is a subsidiary of Heatcon, Inc. and competes predominantly in full-and-open procurements, though it holds several small-business-set-aside IDICs with Defense Logistics Agency Aviation and single-award contracts with Naval Air Warfare Center.

Heatcon's customer concentration centers on defense logistics and naval aviation. Defense Logistics Agency Aviation dominates the portfolio—272 awards carrying $17.3 million in combined potential value across 758 total prime and sub awards in the source data—followed by Naval Air Systems Command and Naval Air Warfare Center combined (38 awards, $14.7 million potential value), Naval Supply Systems Command (36 awards, $3.7 million), and DLA Land and Maritime and DLA Troop Support Construction and Equipment (102 and 100 awards respectively, carrying smaller unit values in the $169 thousand and $595 thousand range). The two rankings align closely: DLA Aviation's volume dominance mirrors its dollar concentration. Representative prime work includes a $3.26 million single-award total-small-business-set-aside IDC with DLA Aviation awarded June 3, 2025 for composite repair sets (HCS9200B model) running through June 2030; a $718,520 single-award IDIC with Naval Air Warfare Center awarded February 3, 2026 for composite repair set temp/vac controllers (HCS9200N-02.5) running through February 2028; a $161,550 total-small-business-set-aside purchase order from DLA Aviation awarded August 6, 2025 for a heated debulking/curing table with delivery to Fleet Readiness Center East; a $135,820 firm-fixed-price purchase order from Air Force awarded March 7, 2025 for a hot bonder kit with accessories and tooling; and a $73,768 total-small-business-set-aside purchase order from Pacific Air Forces awarded September 26, 2025 for pre-built composite tool kits with delivery to Yigo, Guam. Activity has remained relatively flat across 2022–2026, averaging 33 awards annually over the past five years, with seven awards posted to date in 2026. The company faces minimal recompete pressure: only one award with ultimate completion inside the next twenty-four months ($60 thousand combined potential value).

Heatcon places task orders against five named parent vehicles, with an Indefinite Delivery Contract (N6833504D0009) carrying nine task orders worth $5.3 million combined potential value as the largest vehicle position, followed by IDC SPE4A622DC119 (seven task orders, $1.1 million), IDC SPM8E009D5B15 (seven task orders, $30 thousand), BPA FA449717A0019 (three task orders, $43 thousand), and IDC FA823221D0004 (three task orders, dollar value not specified in source).

In its subcontractor role, Heatcon delivers dual-zone hot bonders and F-16 support equipment to BAE Systems Information and Electronic Systems Integration Inc. (awards dated February 26, 2024 and February 23, 2026); battle-damage-assessment-and-repair kit materials to Science and Engineering Services LLC (awards dated December 9, 2024, March 21, 2025, and October 24, 2025); B-2 programmed depot maintenance composite materials to Northrop Grumman Systems Corp (award dated September 4, 2025); A-10 universal rudder prepreg fiberglass and materials support to Kihomac Inc. (awards dated March 13, 2023 and January 30, 2024); and Space Launch System universal stage adapter composite materials to an unnamed NASA prime (award dated June 13, 2025).

Heatcon's capability portfolio centers on hot bonder equipment (controllers, dual-zone units, temperature/vacuum controllers), vacuum equipment (pumps, vacuums systems, debulking chambers), composite repair sets and molds, cable assemblies, thermocouple components, and specialized aerospace maintenance tools. The work is classified primarily under NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) and PSC 4920 (Aircraft Maintenance and Repair Shop Specialized Equipment). Top NAICS categories across the portfolio reflect this focus: Other Aircraft Parts and Auxiliary Equipment Manufacturing (208 awards), Instruments and Related Products Manufacturing (110 awards), and Air-Conditioning and Warm Air Heating Equipment Manufacturing (97 awards). Place of performance for the vast majority of work is Seattle, Washington 98188, with recent exceptions including Yigo, Guam (Pacific Air Forces work), Jacksonville, North Carolina (Naval Air Systems Command training device), and subordinate DoD logistics facilities nationwide.
