In early March 2015, the 109th Airlift Wing, the New York Air National Guard LC-130 Ski-Herk unit at Stratton ANGB in Scotia, concluded its twenty-seventh season supporting the National Science Foundation's Antarctic Program as part of Operation Deep Freeze. Airmen from the 109th AW flew 241 missions, delivering more than 3,000 passengers and 2,250 tons of cargo and fuel to Antarctic research stations during the deployment, which began in October 2014. This season also saw the successful deployment of IcePod, an imaging system that can measure the depth of an ice sheet, on the LC-130. About 575 Airmen and seven aircraft were deployed to McMurdo Station during the five-month operation. About 120 Airmen were at McMurdo at any given time.
