SEOUL – The Republic of Korea's military said it will hold a three-day joint exercise with the United States and Japan starting on Wednesday, featuring fighter jets and marine patrol aircraft as well as the US nuclear-powered aircraft carrier USS George Washington.

The "Freedom Edge" exercise is a response to what the ROK military said were threats from the Democratic People’s Republic of Korea, which recently conducted an intercontinental ballistic missile test, drawing condemnation from Seoul, Tokyo and Washington.

The exercise will include ROK and Japanese fighter jets and maritime patrol aircraft, as well as the USS George Washington, Seoul's Joint Chiefs of Staff (JCS) said in a statement.

The trilateral exercise follows a first round held earlier this year after the leaders of the three countries agreed at a summit in 2023 to hold annual training drills.

Pyongyang has long condemned joint drills between the ROK and the US, calling them a rehearsal for invasion.

The trilateral exercise will also include maritime missile defense training and cyber defense training, according to the JCS.

In a statement on Tuesday, the US Air Force said it would retire its A-10 Thunderbolt II aircraft in key regions including the ROK in the fiscal year 2025 as part of its modernization strategy.

The aircraft, nicknamed "The Warthog", was developed for the US Air Force by the Fairchild Republic Company, which is now part of Northrop Grumman, according to the US defense company's website.
