The Island Air Defence (IAD) System, a networked air defence System-of-Systems (SoS) which protects Singapore against a wide spectrum of threats, was designed and implemented by DSTA. The team has continued to enhance the air defence capability, strengthened system design with increased capacity and redundancy, and improved on the IAD SoS integration testing methodology and processes.
One of the IAD System’s development involves the integration of the SPYDER short-range air defence weapon, for which the team received the Defence Technology Prize 2016 Team (Engineering) Award. By networking a suite of sensors, weapons and C3 systems together, the IAD System provides an enhanced and robust air defence shield for Singapore, with reduced equipment and manpower.
The scale and complexity of IAD SoS, with systems in various locations, required significant time for tests. To address the apportioning of time for system development work while operations were ongoing, the team developed several frameworks and processes that helped manage verification and validation, as well as resources. The team also developed innovative test tools such as message translators and system emulators to stress load the network and validate the IAD System’s performance under maximum load condition.
The multi-disciplinary team worked closely to manage project development and support ongoing operations. Today, the team continues to leverage various opportunities, such as when providing exercise support to the RSAF, to better understand their operational requirements. The team also works closely with the RSAF to incorporate emerging technologies in the development of future capabilities and new concept of operations for the IAD System.
