High-performance computing for a rapidly evolving battlespace

The nature of the battlespace is fast changing and requires swift adoption of new technology and greater procurement agility to find flexible solutions that can be fielded across a range of scenarios. In response to increasingly complex threat challenges, it is vital to maintain a ‘full spectrum’ capability across land, sea, and air, as well as AI, space, cyber and the creation of sensor-laden connected hardware capabilities.

Defence investment is increasing globally to enhance the lethality, precision and reach of weapons, communication range, and other support services to address new and quickly developing threats.
