Siller Helicopters, LLC

Siller Helicopters, LLC (doing business as Siller Helicopters Inc.) operates as a small-business prime contractor delivering aerial firefighting and emergency response helicopter services to the National Interagency Fire Center under full-and-open, non-set-aside federal contracts. The Yuba City, California-based company is a child entity of Helicopter Express LLC and competes on merit in lowest-price technically acceptable procurements, holding a $50 million multiple-award IDIQ (Type 1 Helicopter Support Services 2025-2034) and the prior $26.5 million Basic Ordering Agreement (12024B20G5056) from the U.S. Department of Agriculture Forest Service.

Siller Helicopters delivers specialized rotary-wing aerial firefighting services using a fleet of Type 1, 2, and 3 helicopters equipped with water buckets, tanks, hoists, and advanced firefighting systems. Core mission capabilities include fire suppression, water bucket drops, aerial ignition, air tactical supervision, short-haul and rappel operations, reconnaissance, and emergency response. All delivery orders under both the current and legacy IDIQ vehicles carry firm fixed-price terms. Recent representative work includes a $1.65 million delivery order from NIFC in August 2026, a $15.4 million Total Small Business set-aside delivery order for Grantsdale, Montana operations issued May 2025, a $12.97 million Total Small Business set-aside for Placerville, California issued May 2025, and $1.38 million and $1.29 million delivery orders from September 2024. The company operates exclusively as prime contractor with no subcontractor engagement across its federal footprint.

Customer concentration is extreme and singular. The Department of Agriculture Forest Service Fire and Aviation Management National Interagency Fire Center accounts for 212 awards (99% of total) and $428.6 million (99.98% of combined potential value). The Department of the Interior National Park Service Pacific West Region holds 2 awards valued at $48 thousand. This laser focus on NIFC wildfire suppression contracting reflects Siller's specialized operational model and the seasonal, call-when-needed nature of aerial firefighting procurement.

Siller holds two parent vehicles: the newly awarded Type 1 Helicopter Support Services 2025-2034 IDIQ ($50 million ceiling, 67 delivery orders totaling $74.2 million as of the source date) and the legacy Basic Ordering Agreement 12024B20G5056 ($26.5 million, 138 task orders totaling $79.9 million). The BOA, awarded January 1, 2020, ran through December 31, 2024 and supported seasonal fire suppression operations from Yuba City with two-hour mobilization capability. The new IDIQ, effective January 1, 2025 through December 31, 2034, extends the same mission set across a ten-year period with optional one-year extensions. Both vehicles procure through lowest-price technically acceptable competition with no set-asides.

Activity has declined from 55 awards in 2022 to 32 in 2026 year-to-date, reflecting the source snapshot's August–September 2026 capture point (partial year). The vendor faces no published recompete cliff within the source data window; the legacy BOA expired end of 2024, and the new IDIQ extends through 2034. The majority of delivery orders issued in recent months carry ultimate completion dates of December 31, 2029 or December 31, 2024 (legacy BOA orders), reflecting seasonal fire campaign cycles.

Service Contract Inventory data shows zero invoiced revenue reported across FY2022–FY2025 and zero FTE trajectory in the SCI dataset, indicating that Siller's federal work—valued at $428.7 million in combined potential across 214 awards—is captured as goods/products (aircraft and aviation services under NAICS 488190, PSC 1560) rather than as labor-intensive service contracts above the $150,000 SCI threshold. The vendor reports neither subcontractor hours nor sub-engagement in the SCI records, confirming prime-only delivery posture.

Siller Helicopters competes in a specialized, non-set-aside, full-and-open federal market with no SBA certifications cited in the source. The company is positioned as a sole-source supplier for Type 1 helicopter aerial firefighting to federal land management agencies through established IDIQ and BOA vehicles, with proven rapid-response capability and extensive experience mobilizing specialized aircraft for emergency fire suppression operations across the U.S. Forest Service, Department of Interior, Bureau of Land Management, and National Park Service jurisdictions.
