The United States has approved the sale of more than $4 billion in military helicopters to South Korea, the latest in a series of major arms transactions as Washington presses its allies to shoulder more of their own defense costs.
The State Department cleared South Korea to purchase 24 "Romeo" Seahawk naval helicopters in a deal valued at $3 billion, along with a separate $1.2 billion package to upgrade Seoul's existing fleet of Apache attack helicopters.
The Seahawk, a carrier-based rotary aircraft, is designed to track and destroy submarines as well as engage land targets, making it a versatile asset for a peninsula military that faces a persistent underwater threat from North Korea.
According to a State Department statement, the sale will improve South Korea's "capability to meet current and future threats" and support a "credible force that is capable of deterring adversaries."
The approval comes against the backdrop of a sweeping defense commitment made by South Korean President Lee Jae Myung during a summit with President Donald Trump.
Lee pledged that Seoul would purchase $25 billion in U.S. military equipment by 2030 and contribute $33 billion to support American forces stationed on the peninsula, a force of roughly 28,500 troops that has anchored the bilateral security alliance since the Korean War.
Trump has made defense burden-sharing a central demand of his foreign policy, repeatedly pressing NATO members and Asian allies alike to increase military spending and questioning the rationale for maintaining U.S. forces abroad.
Lee, who took office as a relative moderate, has advocated direct talks with Pyongyang without preconditions, a departure from the harder line favored by his conservative predecessors.
That outreach has so far gone unanswered. North Korea has shown no willingness to engage, leaving the inter-Korean relationship effectively frozen.
The diplomatic picture with Washington is complicated by Trump's own unpredictable history with Pyongyang.
During his first term, Trump held three face-to-face meetings with North Korean leader Kim Jong Un, at one point claiming the two had "fell in love," an unusual characterization that drew widespread attention.
In his current term, however, North Korea has received little visible attention from the administration.
The two helicopter platforms at the center of the sale come as different dimensions of South Korea's defense needs.
The MH-60R Seahawk, produced by Lockheed Martin's Sikorsky division, is the U.S. Navy's primary anti-submarine warfare helicopter and is in service with several allied navies.
The AH-64 Apache, manufactured by Boeing, is one of the most widely deployed attack helicopters in the world, capable of engaging armored vehicles and fortified positions.
South Korea already operates Apaches, and the approved package would bring its existing fleet up to current specifications.
