Beginning in 1955, annual Operation Deep Freezes were conducted in the Antarctic for
scientific studies and exploratory expeditions of the region. At least one icebreaker
was involved in each operation, with the majority accompanied by two icebreakers.
Their primary responsibility was in breaking the ice from the paths of the conventional
vessels carrying the bulk of personnel and equipment. Beyond breaking the ice,
these vessels also conducted search and rescue missions and participated in meteorological
and oceanographic studies. Helicopters launched from the icebreakers also provided
a range of services: surveying, meteorological data gathering, transportation, and
logistical support.
