South Korea’s domestically developed fighter, the KF-21 Boramae, has moved beyond development and entered serial production. The country’s aerospace industry, centered in Sacheon in Gyeongsangnam-do, is gearing up for a major push into global markets.

Gyeongsangnam-do said it held a successful rollout ceremony for the first production KF-21 at Korea Aerospace Industries (KAI) headquarters in Sacheon on the afternoon of the 25th. About 500 people attended, including President Lee Jae-myung, Gyeongsangnam-do Governor Park Wan-su, officials from the Ministry of National Defense and the Defense Acquisition Program Administration, Air Force representatives and development personnel, who marked a new milestone in South Korea’s aviation history.

The first production jet is significant because every step—from design and manufacture to testing—was completed within the province. The KF-21 is more than a weapons system; it represents a concentrated body of South Korean aerospace technology and a strategic asset for Gyeongsangnam-do.

The event featured an unveiling of the aircraft, a vision video outlining next-generation fighter plans, and a celebratory flypast by the Air Force’s Black Eagles aerobatic team, underscoring the capabilities of Korea’s defense sector. The rollout confirms the KF-21 is on track for stable operational fielding and signals that entry into the global fighter market is imminent.

Park Wan-su, governor of Gyeongsangnam-do, said in his congratulatory remarks, “The rollout of the first production KF-21 marks a historic turning point as K‑aerospace moves from manufacturing to operational deployment and exports. We will marshal all provincial administrative resources to help Gyeongsangnam become a world-class aerospace hub.”

Gyeongsangnam-do plans to use KF-21 production as a springboard to expand the industrial ecosystem. Officials singled out plans to establish an advanced aero-engine cluster and to build a civil-military integrated aviation maintenance, repair and overhaul (MRO) hub, aiming to secure end-to-end competitiveness across the aerospace sector.

International interest was strong. Ambassadors from 13 countries and defense attaches attended the rollout, including representatives from co-development partner Indonesia, all expressing keen interest in the KF-21’s performance and production system.

The province intends to build on the momentum at the Sacheon Airshow: Aerospace and Defense Industry Exhibition this October, using the event as a platform to promote exports.

Officials said they will strategically invite potential buyers from target markets and conduct focused sales consultations as part of an all-out campaign to market K‑defense products.

As KF-21 production ramps up, Gyeongsangnam-do expects increased orders for local aerospace parts suppliers and significant job creation, injecting new momentum into the regional economy.
