President Donald Trump has dismissed Kristi Noem from her position as Secretary of the U.S. Department of Homeland Security (DHS), concluding her term during which she made significant changes to various maritime policies. These changes included historic funding for modernizing the Coast Guard and seizing tankers related to sanctions against Venezuela.
The White House announced that Trump intends to nominate Markwayne Mullin to head the DHS, which oversees the U.S. Coast Guard and plays a crucial role in maritime security, enforcing sanctions, and counter-drug operations.
Noem's leadership included a mix of major modernization efforts and controversial decisions in shipbuilding that impacted the U.S. maritime industry.
One major achievement during Noem’s time was the passing of the "One Big Beautiful Bill," which allocated approximately $25 billion for the modernization of the Coast Guard, marking the largest investment in its history. This funding aims to upgrade the Coast Guard’s aging ships and aircraft while enhancing its abilities in Arctic operations, maritime security, drug interdiction, and border enforcement.
A key focus of the modernization effort was the significant expansion of the U.S. icebreaker fleet, which has become increasingly important for national security and competition in the Arctic.
Currently, the Coast Guard operates just two polar-capable ships: the heavy icebreaker USCGC Polar Star and the medium icebreaker USCGC Healy.
Under Noem’s leadership, DHS supported increased procurement for the Polar Security Cutter and Arctic Security Cutter programs. The funds from the modernization package will allocate billions towards these new ships, potentially allowing the Coast Guard to significantly expand its fleet of polar-capable vessels in the coming decades.
This expansion is timely as the U.S. seeks to counter Russia’s dominance in icebreaker capabilities and respond to growing Chinese interests in Arctic shipping routes and related infrastructure.
Leaders within the Coast Guard argue that rebuilding the icebreaker fleet is crucial for maintaining year-round access to polar regions, supporting scientific missions, securing emerging shipping routes, and demonstrating U.S. presence in the Arctic.
While managing a historic modernization funding package, Noem also oversaw several controversial shipbuilding decisions that affected Coast Guard acquisition programs.
DHS canceled plans for the 11th Legend-class National Security Cutter, which was under contract with Huntington Ingalls Industries. The department stated that this move would save about $260 million while redirecting funds to maintain and support the current fleet.
The department also partially halted parts of the Coast Guard’s Offshore Patrol Cutter program, impacting work at Eastern Shipbuilding Group due to rising costs and delays in scheduling.
In addition to shipbuilding policies, Noem oversaw a more proactive maritime enforcement approach related to sanctions and counter-narcotics operations targeting Venezuela's oil trade.
In December, U.S. authorities seized a tanker identified as the VLCC Skipper, which was allegedly transporting Venezuelan crude using deceptive practices. The vessel reportedly had around 1.8 million barrels of crude oil when it was intercepted. The case later turned into a civil forfeiture action by the U.S. Department of Justice seeking to confiscate both the tanker and its cargo.
During her testimony before Congress, Noem described this seizure as part of a broader strategy to disrupt criminal networks involved in both sanctions evasion and drug trafficking.
“We will not allow regimes that flood our country with drugs to benefit from illegal oil shipments,” she told lawmakers, connecting the tanker seizure to larger counter-drug efforts.
Further tanker interceptions occurred as part of a wider maritime enforcement campaign aimed at vessels suspected of carrying Venezuelan oil using tactics like false registries and AIS manipulation.
Noem also highlighted notable major maritime drug seizures during her time in office, with the Coast Guard intercepting large amounts of cocaine and other narcotics along trafficking routes in the Eastern Pacific and Caribbean.
These interceptions, worth hundreds of millions of dollars, showcased the Coast Guard as a primary force in fighting transnational criminal organizations at sea.
Noem's departure comes amid rising global maritime tensions, including escalating conflicts in the Middle East and increasing rivalry in the Arctic. The leadership change also arrives as the Coast Guard faces growing responsibilities related to counter-drug missions, enforcing sanctions, ensuring Arctic security, and safeguarding new polar shipping routes.
Mullin, nominated for the DHS secretary position, served in the U.S. House from 2013 to 2023 and was part of the House Transportation and Infrastructure Committee, supporting legislation related to shipping emissions and maritime modernization. If confirmed, he will oversee one of the most ambitious Coast Guard modernization efforts in decades while managing an ever-changing maritime security landscape.
