South Korea’s Hanwha Aerospace has successfully completed acceptance trials for a domestically-developed engine tailored for the K9 self-propelled howitzer, marking a significant milestone in the advancement of its defense capabilities. The intensive trials spanned a year and were conducted in various locations, including South Korea and Egypt, as well as other international settings.
During these trials, the engine underwent rigorous testing, accumulating over 10,000 kilometers (approximately 6,214 miles) of evaluation in a variety of conditions, including extreme desert environments. Developed by STX Engine, this new 1000-horsepower engine is designed to outperform the existing German MTU diesel engine, which had previously been manufactured under license by STX Engine.
The improvements are notable, with the domestic engine being lighter and more fuel-efficient than its predecessor, enhancing the operational capabilities of the K9 howitzer. Besides its performance benefits, the new engine’s design allows for customization according to specific customer needs—an advantage that also facilitates exportation without the need for approvals from foreign governments. This development is expected to significantly boost the export potential of the howitzer.
Kim Dong-hyun, Head of the Land Systems Business Group at Hanwha Aerospace, expressed optimism regarding the engine’s implications for international sales. “With the successful completion of the homegrown engine test, we can offer specialized engines to any potential K9 customers, which is expected to expand K9’s global presence,” he stated. This initiative forms part of Hanwha’s broader strategy to diversify its portfolio in line with the evolving demands of global clients.
The new engine is set to be installed in the hundreds of K9 units that Egypt acquired for $1.7 billion in 2022. This procurement also includes K10 ammunition resupply vehicles and K11 fire control vehicles. The initial batch of K9A1EGY (the Egyptian variant) is anticipated to be delivered by the first quarter of 2026.
Currently, the K9 howitzer is in service with ten nations worldwide, including six NATO members, attesting to its growing reputation and effectiveness on the battlefield. The weapon system boasts the capability to engage targets at ranges exceeding 40 kilometers (about 25 miles) and is designed for “shoot and scoot” operations to minimize the risks associated with counter-battery fire. This ongoing advancement in the K9’s technology underlines South Korea’s commitment to enhancing its defense industry and solidifying its position in the global arms market.
