This past September 11 saw a first in aviation history – a C-17 Globemaster III aircrew from McChord Air Force Base, Washington, performed the first known after-dark landing in Antarctica using night vision goggles. Combined with the use of reflective cones, the aircrew was able to verify the C-17’s capability to access McMurdo Station and successfully land in complete darkness.
The mission was flown as part of Operation Deep Freeze, which is commanded by US Pacific Command’s Joint Task Force Support Forces Antarctica. The job of JTF SFA is to provide air and sealift support to the National Science Foundation and US Antarctic Program.
Antarctica does not receive any sunlight for several months of the year, usually from late March to mid-August. The night vision goggle concept helps aircrews to safely and easily get into Earth’s southernmost continent regardless of the time of the year.
There are many reasons the National Science Foundation may need strategic airlift during winter months, said Maj. Corey Simmons, an evaluator pilot with McChord’s 62nd Operations Support Squadron and one of the pilots on the mission.
“There could be a contingency operation where someone is sick or hurt down here during the winter-over months, when they have complete darkness for four and a half months,” he said. “We have the capability now to get them out.”
Lt. Col. Jim McGann, commander of the 304th Expeditionary Airlift Squadron and the night vision goggle concept’s chief architect, adds, “Previously, we couldn’t physically light the entire runway; it wasn’t possible. Now, with the inherent [night vision goggle] capability in the C-17, the increased technological advances in night vision goggles, and 64 high-intensity retro-reflective cones placed on the runway edge, we can leverage the technologies and say, ‘Let’s see if we can get in there and access McMurdo at night.’
“We found the cones to be very good at illuminating the runway and providing critical situational awareness. When the aircraft turns to final [approach], the wingtip light reflects off the cones to the [night vision goggles] and we can see the entire runway.”
And even though they are not powered, the cones light up “like Christmas trees,” said Maj. Simmons. “Even if you looked under the [night vision goggles] with the naked eye, you could see these things from two or three miles out coming in to Pegasus. So the safety factor that we were able to give to this type of mission by adding something like this is exponential.”
The use of night vision goggles and reflective cones on the ground capitalizes on an inherent strength of the C-17 Globemaster III – the aircraft is built for night vision operations. Its Heads-Up-Display shows all of its operating parameters directly in front of its pilots on a piece of glass, allowing them to use night vision goggles to survey the area while keeping a close eye on the C-17’s performance at the same time.
Lt. Col. McGann said the concept will open up many opportunities for the National Science Foundation and US Antarctic Program. “ Now [the National Science Foundation]…can take advantage of the full capabilities of the C-17.”
