The US has long promoted its advanced F-35 fighter jet to allied nations, including India, but New Delhi has consistently shown little interest in acquiring the costly aircraft. Meanwhile, in a strategic move to counter American dominance in the defense sector, South Korea, partnering with Indonesia, has developed the 4.5-generation KF-21 Boramae fighter jet. Positioned as a competitor to France’s Rafale, which is already a key asset in the Indian Air Force, this new aircraft marks a significant shift in the regional aerospace landscape.

First Test Flight In 2022

The KF-21 Boramae is being hailed as a significant step by South Korea towards altering the military balance in Asia. Korea Aerospace Industries (KAI) developed the jet in partnership with Indonesia. The KF-21 Boramae is a modern 4.5 generation multi-role fighter jet designed to reduce dependence on American aircraft and bolster the domestic defence industry. The first test flight of the KF-21 took place on July 19, 2022.

Capabilities And Specifications

The KF-21 can establish air supremacy and accurately target ground and sea targets. The aircraft is 16.9 metres long, has a wingspan of 11.2 metres, and is powered by two General Electric F414-GE-400K turbofan engines, allowing it to reach a top speed of 2,200 km/h (Mach 1.81). Its range is approximately 2,900 km, with a combat radius of around 1,100 km.

Stealth And Weaponry

The KF-21 features 10 hardpoints, capable of carrying a payload of up to 7,700 kg. It can be equipped with advanced air-to-air missiles such as the AIM-120 AMRAAM, Meteor, and IRIS-T, as well as JDAM and Mk series bombs and anti-ship missiles. The aircraft also has a 20 mm M61A2 Vulcan cannon. Future upgrades will include an internal weapon bay and enhanced stealth features. While not entirely ‘invisible’ like the F-35, its design and materials significantly reduce radar detection.

Projected Production Timeline

The KF-21 incorporates South Korea’s indigenous AESA radar, a high-tech glass cockpit, and a modern data link system. The total project cost is estimated at $7.9 billion, with each aircraft priced between $65 and $70 million. South Korea plans to induct 120 KF-21s into its air force by 2032, with around 50 aircraft to be built for Indonesia.
