South Korea's Naval Triumph: HD HHI Delivers Advanced Aegis Destroyer 'ROKS Jeongjo the Great'

In a significant stride for South Korea's defense capabilities, HD Hyundai Heavy Industries (HD HHI) has officially handed over the cutting-edge Aegis destroyer, ROKS Jeongjo the Great, to the Republic of Korea Navy. The delivery ceremony, held on November 27 at HD HHI’s shipyard in Ulsan, underscored South Korea’s emergence as a leading force in advanced naval shipbuilding. Dignitaries from seven nations, including representatives from the United States, Poland, and Peru, were present, emphasizing the global interest in the country’s growing naval expertise.

A Pinnacle of Naval Engineering

The ROKS Jeongjo the Great, an 8,200-ton vessel from the KDX-III Batch-II class, represents a leap in design and technology compared to its 7,600-ton predecessor. It is South Korea’s fourth domestically designed Aegis destroyer and a testament to the nation's capability in integrating imported and indigenous systems. Key features include:

• Advanced Combat Systems: The ship integrates the latest U.S.-built Aegis combat system with South Korea’s Korean Vertical Launch System (KVLS-II), capable of deploying ballistic missile interceptors, long-range surface-to-air missiles, and surface-to-land ballistic missiles.

• Stealth and Detection: Enhanced stealth capabilities are complemented by a domestically developed integrated sonar system, offering superior underwater detection and response.

• Multi-Mission Readiness: The vessel is equipped with MH-60R Seahawk maritime helicopters for anti-submarine warfare and long-range strike missions.

• Hybrid Propulsion: Four gas turbine engines and a Hybrid Electric Drive (HED) system deliver a blend of high-speed capability and fuel efficiency.

Strategic Impact

The Jeongjo the Great is a linchpin of South Korea’s “Sea-Based Maneuvering Three-Axis System,” a strategic initiative designed to counter North Korea’s missile and nuclear threats. Its capabilities support integrated underwater kill chains, layered missile defense, and precision strike operations, strengthening the nation’s deterrence posture.

Meticulous Development and Testing

Construction of the Jeongjo the Great began in 2021 following a 2019 contract with South Korea's Defense Acquisition Program Administration (DAPA). The ship underwent rigorous testing, completing over 550 evaluations, including high-speed trials, before its delivery. This milestone reflects HD HHI’s reputation for adhering to deadlines and delivering high-performance naval assets, including the Ulsan-class frigates and the Shin Chae-ho submarine.

A Global Showcase

The delivery ceremony also highlighted South Korea’s ambitions in defense exports. Attendees toured HD HHI’s Naval & Special Shipyard and previewed the ROKS Chungnam, a state-of-the-art frigate set for delivery next month. Representatives from countries such as Poland and Peru, identified as potential buyers of South Korean defense products, were among the guests.

HD HHI’s leadership emphasized their commitment to strengthening K-defense exports through close collaboration with international partners. The company has already initiated projects with nations like the Philippines and Peru, including patrol vessels and joint ship development programs.

A Future of Naval Innovation

As HD HHI prepares to launch the second Jeongjo the Great-class destroyer next year and continues construction on the third, the company is setting benchmarks in naval technology. This class of destroyers, equipped with multi-role combat capabilities and advanced propulsion systems, underscores South Korea’s commitment to modernizing its naval forces and contributing to global maritime security.

With its successful delivery of the ROKS Jeongjo the Great, HD HHI has solidified its position as a leader in advanced naval shipbuilding, paving the way for further innovations and strategic partnerships.
