The U.S. State Department has given the green light for the sale of 36 AH-64E Apache helicopters to South Korea, a deal valued at approximately $3.5 billion.

The Defense Security Cooperation Agency (DSCA), a branch of the U.S. Department of Defense, announced the approval on Monday, underscoring the sale’s significance in bolstering South Korea’s defense capabilities amid ongoing regional tensions.

The deal, requested by South Korea, includes not only the Apache helicopters but also a range of essential equipment and support services. Among the items included are up to 76 T700-GE-701D engines, 36 Modernized Target Acquisition and Designation Sights/Modernized Pilot Night Vision Sensors, 14 Fire Control Radars with Mast Mounted Assemblies, and Radar Electronic Units.

The AH-64E Apache, regarded as one of the most advanced attack helicopters in the world, is equipped to perform in day and night operations and under all weather conditions. With a maximum cruising speed of 269 kilometers per hour, the Apache can carry a formidable array of armaments, including Hellfire missiles and up to four Stinger air-to-air missiles.

This purchase comes as South Korea seeks to enhance its military capabilities in response to the growing threat posed by North Korea. The Republic of Korea Army has already been operating 36 AH-64E Apache helicopters since 2017, following a previous purchase from the United States. The new acquisition not only includes additional helicopters but also operational support systems aimed at upgrading the performance of the existing Apaches.

The Apache helicopter, which has been in service with the U.S. military for 40 years, has undergone continuous upgrades, ensuring it remains at the forefront of attack helicopter technology.
