"Increase Collaboration with South America to Protect U.S. Antarctic Interests"

The United States has significant national interests in Antarctica, but it currently lacks the maritime capacity to secure them. The United States sent more commercial vessels (42) and citizens (over 50,000) to the Southern Ocean than any other country during the 2023/2024 season. The United States, unlike many other nations, can also conduct unannounced inspections of stations and equipment in the region. However, the U.S. government is reducing its icebreaker capacity in the region by removing two vessels from service, continuing to rely on one heavy icebreaker that is beyond its expected service life. As of this writing, the United States has yet to take concrete steps to design and build appropriate vessels to ensure continued access in the region.
While Washington has acted to eventually address icebreaker shortcomings in the Arctic, it has not taken similar steps to protect its Antarctic interests. Therefore, as it starts the lengthy process of planning and building Polar Security Cutters for Antarctic operations, the United States should increase its collaboration with South American countries. Doing so will strengthen already-positive relations with key South American countries, protect American citizens and economic interests, and help the United States leverage Antarctic Treaty provisions to maintain peace in the region amid growing geopolitical interests.

March is the month of the famous carnivals in South America. However, the month also signifies the end of the Antarctic summer campaigns. Argentina and Chile are two of the seven countries that claim Antarctic territory, but other South American countries are also present on the frozen continent. The cornerstone of these annual campaigns, unsurprisingly, is the armed forces. As Antarctica’s importance grows, it is necessary to understand the strategies and objectives of South American governments toward the southernmost region. And to do that, we need to understand the role of South American militaries.
