Hanwha Aerospace Develops South Korea’s First Indigenous 4500-lbf Turbofan Engine

On May 26, 2026, Hanwha Aerospace and the Korea AeroSpace Administration (KASA) officially launched a joint development program to produce South Korea’s first indigenous 4,500-pound-force (lbf) turbofan engine. According to the official press release, the engine is targeted for operational deployment by 2029 and is designed primarily to power Collaborative Combat Aircraft (CCA) and unmanned aerial vehicles (UAVs).

We note that this initiative represents a critical milestone in South Korea’s pursuit of aerospace self-sufficiency. Historically reliant on foreign military engines, Seoul is now positioning itself as a top-tier player in the rapidly expanding global market for autonomous military systems, aiming to end its dependence on external supply chains.

Technical Specifications and Innovations

The 100 kW Embedded Starter-Generator

The new high-bypass turbofan engine will generate 4,500 lbf (2,040 kg) of thrust. While optimized for military UAVs, the program details note that the engine maintains a dual-use architecture, meaning it could eventually be adapted for civil aviation applications such as small commercial business jets.

A major technical innovation highlighted in the development plan is the inclusion of an embedded starter-generator. Rather than utilizing a traditional external unit, the generator will be integrated directly onto the engine’s rotating shaft. According to industry research, this design choice significantly reduces the overall weight of the engine, thereby improving flight performance and efficiency.

Crucially, this embedded generator is designed to reliably supply up to 100 kilowatts (kW) of electrical power. Defense analysts emphasize that this high power output is essential for modern autonomous combat aircraft, which require substantial electricity to run advanced artificial intelligence computing, sensor arrays, radar systems, and electronic warfare systems.

Strategic Funding and Market Implications

A Billion-Dollar Investment in Autonomy

The project is being led by Hanwha Aerospace, South Korea’s largest defense conglomerate, in collaboration with KASA, the Korea Aerospace Research Institute (KARI), various universities, and domestic subcontractors.

Financial commitments to the program are substantial. According to industry reports, KASA has allocated approximately 900 billion won (roughly $650 million) in state funding between 2026 and 2029 for this next-generation dual-use aircraft engine program. In tandem, Hanwha Aerospace plans to invest an additional 750 billion won (approximately $498 million) to build out a comprehensive drone engine portfolio.

This 4,500-lbf engine is part of a broader government-backed UAV propulsion strategy. Hanwha is also reportedly developing a 5,500-lbf low-bypass turbofan for low-observable unmanned wingman aircraft, as well as core technologies for a 10,000-lbf turbofan intended for larger stealth platforms.

AirPro News analysis

We view this combined investment of over $1.1 billion as a clear declaration of aerospace independence by South Korea. Currently, the domestically built KF-21 Boramae fighter jet relies on the American General Electric F414 engine. By developing an indigenous turbofan, South Korea mitigates the vulnerability of potential export restrictions and strengthens the resilience of its national defense supply chain.

Furthermore, securing domestic technology for the “heart of the unmanned fighter” positions South Korea to capture a significant share of the global CCA market. Industry forecasts expect the CCA market to exceed 3,000 units by the 2040s. If Hanwha successfully produces a reliable and affordable turbofan by 2029, South Korea will possess a highly lucrative export product for allied nations developing their own drone programs.

Liselotte Odgaard, a Senior Fellow at the Hudson Institute, noted that Seoul’s attempt to indigenize this complex drone technology should be viewed as a “deliberate bid to enter the top tier of UAV producers.”

Frequently Asked Questions (FAQ)

What is a Collaborative Combat Aircraft (CCA)?

The Collaborative Combat Aircraft concept represents a major shift in military aviation. Instead of deploying manned fighters alone, the CCA model pairs them with AI-powered “loyal wingman” drones that can scout ahead, jam enemy radars, or carry additional munitions to support the primary manned aircraft.

Why do modern drones require 100 kW of electrical power?

As aircraft become increasingly “electrified,” they rely on power-hungry onboard electronics. A 100 kW output is necessary to support the intense computing requirements of artificial intelligence, as well as advanced sensors, radar systems, and electronic warfare equipment required on the modern aerial battlefield.
