Defence’s electromagnetic spectrum challenges

Richard Wolf

The Australian Defence Force is ill prepared for a modern conflict. It is not doing nearly enough to ensure dominance of the electromagnetic spectrum (EMS), the kind of energy used in communications and by many sensors.

The ADF must fully exploit the EMS to command forces, to direct weapons and to know what’s going on, and it must be able to prevent an enemy from doing the same.

In some areas, it is well equipped for these tasks but in others far too weakly. The biggest gaps are in maritime, air and space sensors and effectors; spectrum awareness; and communications. Some projects to improve capability are publicly disclosed, though not in any detail, and maybe a few more are proceeding behind the scenes.
