Over 200 South Korean and US fighter jets are scheduled to conduct round-the-clock flights for five consecutive days this week, marking the largest number of training sorties by the allies, according to South Korea's air force on Tuesday.

These exercises are part of the annual Ulchi Freedom Shield drills aimed at enhancing the joint defense readiness of South Korea and the US against potential threats from North Korea.

The drills involve defensive patrol aircraft being redirected to simulate air combat situations, including mock enemy aircraft interception and cruise missile defense scenarios.

Participating in the drills are aircraft from two US fighter wings stationed in South Korea, where the United States maintains 28,500 troops for combined defense against North Korea's nuclear capabilities.

North Korea frequently criticizes the Ulchi Freedom Shield exercises, which commenced on Monday and will continue until August 29, accusing them of escalating tensions on the Korean peninsula and labeling them as preparations for a nuclear war.

Despite efforts to modernize its air force, North Korea struggles with the introduction of new aircraft, primarily relying on outdated models, including some vintage Soviet MiG fighters from the 1950s.

Pyongyang has intensified its tactical warfare capabilities, focusing on short-range missiles and heavy artillery designed to target the South, following significant advancements in its longer-range ballistic missile and nuclear programs.
