The defence of Singapore has been bolstered with the acquisition of new advanced sensors and air defence weapons. DSTA designed local command and control (C2) systems to integrate these advanced systems into the nation’s multi-layered air defence system.

Before such guided weapons are incorporated into the sophisticated system, it is necessary to analyse the compatibility of these weapons with the sensors in the networks. DSTA developed comprehensive methodologies which would allow the performance of air defence weapons to be assessed when there is a need to integrate them with existing sensors and communications network.

Previously, such assessments were performed by the manufacturers of these systems, while DSTA focused on delivering the integrated solution through selected analyses, ground tests and live-firing tests. There was no methodology or tool to perform end-to-end analysis of a networked system’s performance. DSTA established new methodologies and models, while ensuring that several factors, including accuracies, network latencies and system errors, were addressed to meet the Singapore Armed Forces’ unique operational requirements.

Independent engineering development as well as testing and validation of the model were conducted. To this end, the results of analyses can now be seen within minutes. In addition, the tool can perform independent checks on the achievable performance of an integrated sensor-shooter system. Based on preliminary weapon specifications, tests can be performed before the actual acquisition. These methodologies have enhanced DSTA’s capability to conceptualise, design and analyse the Networked Air Defence system in dealing with any form of aerial threats.
