SAF Digital and Intelligence Service — Fourth Service

In October 2022, Singapore's Ministry of Defence formally established the SAF Digital and Intelligence Service (DIS) as the fourth Service alongside the Army, Navy, and Air Force, with sole responsibility for digital and intelligence operations, cyber defence, and AI decision support. In 2025, DIS was further reorganised into two commands: DCCOM (Digital Cyber Command) and SAFC4DC (C4 and Defence Computing Command). This is the deepest structural move in Singapore's national AI-native strategy — writing AI into the Service structure itself rather than running it as a departmental project. Supporting elements include the DIS × AI Singapore MoU, the DIS Sentinel Programme with AI curriculum, and upgrades to the SAF Digital Range / CyTEC.
