McMurdo Station

McMurdo-based aircraft, including helicopters, fixed wing aircraft, and uncrewed aircraft systems (UAS) will continue to support USAP researchers and program logistical functions.

Helicopters

Pathfinder Aviation, LLC

Pathfinder Aviation, LLC (PAA) is contracted by the U.S. National Science Foundation (NSF) to operate up to three helicopters during day shift and up to two helicopters during night shift this season in support of approved research and operational efforts in the vicinity of McMurdo Station.

Missions typically take place in McMurdo Sound, McMurdo Dry Valleys, Royal Society Range, Ross Ice Shelf and Ross Island regions, and will be supported by light (Astar B3s) and/or medium (Bell 212) airframes. Antarctica New Zealand (ANZ) will be contracting an Astar B3 from Southern Lakes Helicopters (SLH) this season. U.S. Antarctic Program aircraft are slated to provide several NSF-approved quid pro quo missions in support of ANZ's 2025-26 field science program as supportable throughout the season.

Fixed Wing Support

The New York Air National Guard 109th Airwing LC-130 Hercules aircraft will provide research and operational support to South Pole Station, and West Antarctic Ice Sheet Divide (WAIS).

Kenn Borek Air

Kenn Borek Air (KBA) will provide three DHC-6 Twin Otter and one DC-3T Basler aircraft to support a number of USAP operations on continent. Both aircraft types will be based out of McMurdo Station, South Pole Station, WAIS Divide, and Union Glacier at different times throughout the season.

Uncrewed Aerial Systems (UAS)

There will be several UAS operating in the McMurdo Station area this season, as well as some field camps. NIWC Air Traffic Control and ASC Aviation Operations will advise aircraft of all UAS activities and deconflict airspace, as required.
