Antarctic missions[edit]

The Paul Buck harbored next to an Ice breaker in Polar Bear Bay

Paul Buck made frequent deliveries of fuel to the Antarctic for resupply. This was the most common route that this ship made delivering a variety of fuel types to the base. It was always escorted by an ice breaker.

In 2010 the vessel was replaced by Empire State[2] and Paul Buck was taken out of service and transferred to the Maritime Commission's National Defense Reserve Fleet. The vessel was laid up in "Interim Hold" as of April 2020.[1]
