3,500-ton attack submarine to get high-tech control module

Exail, a Paris-based company, has commenced production of the sixth advanced steering console for the Republic of Korea Navy’s next-generation diesel-electric attack submarines under the JangBogo III (Dosan Ahn Chang-ho) program. These consoles, integral to submarine navigation and control, are built around Exail’s Opsys integrated computer, which serves as the intelligence core, ensuring precise and reliable operation. Since 2014, Exail has designed, produced, and delivered five such consoles, with the sixth system’s construction starting in 2026 and commissioning planned for 2027. The development of each unit involves nearly two years of multidisciplinary work and includes comprehensive support from integration to onboard commissioning, facilitating long-term knowledge transfer. The steering console is a critical component that unifies navigation, propulsion, and control systems, enhancing mission safety, tactical efficiency, and naval autonomy. Exail’s expertise is underscored by the deployment of 15 pilot stations worldwide, confirming its role as a trusted
