\"An<\/a>The issue of ballistic missile defence (BMD) was a controversial one when US President Reagan first advocated a strategic-level system in the early 1980s. It remains so today\u2014defences against theatre- and tactical-range missiles are gradually improving, but no effective strategic-level system is in sight. Consequently, mutual deterrence will continue to define great-power nuclear relations for many years to come.<\/p>\n

What\u2019s Australia\u2019s interest? We live a long way away from most current ballistic missile arsenals. But the ADF frequently deploys within range of ballistic missile systems, especially in Northeast Asia or the Middle East, and those systems might proliferate more widely in the future.<\/p>\n

We have two questions to decide. The first is the priority for enhancing the ADF\u2019s own BMD capabilities. The second is whether it makes sense for us to participate in a cooperative arrangement with the US or other partners.<\/p>\n

In evaluating the effectiveness of BMD systems, there are three main factors to consider: the range of the ballistic missiles, the sophistication of countermeasures that the missiles employ, and the number of missiles employed in an attack. BMD systems have a good chance of working against a small number of short-range missiles with simple (or no) countermeasures. But the defensive task gets rapidly harder against more complicated attacks, and even defences that are effective against small attacks can easily be overwhelmed by larger ones. In the most challenging case\u2014an attack that involves a large number of long-range missiles with sophisticated countermeasures\u2014the defence has no chance of protecting the target. Those factors mean ballistic missiles will retain strategic potency for years to come\u2014and could prove to be an especially disruptive technology in a maritime area-denial role.<\/p>\n

At the moment, defences lag behind the capabilities of offensive missile systems. Whether the gap can eventually be bridged is an open question (although potential saturation of the defences will always be a problem). But a system of only limited capability can still have important effects. As well as providing a measure of defence against forces with limited missile numbers or capability, it can take the \u2018cheap shots\u2019 off the table in a crisis and it can complicate the decision-making of adversaries.<\/p>\n

For Washington, even a limited missile defence can better assure allies and partners, as well as Americans, that they\u2019re not hostage to every missile-equipped rogue. And it can make the US more willing to deploy its principal conventional weapons\u2014such as aircraft carriers\u2014in harm\u2019s way (although probably only where threat capabilities and numbers are limited).<\/p>\n

For Australia today, the strongest argument for committing to greater efforts in the BMD field lies in our possible alliance role in the broader western Pacific. The US is grappling with the problems posed by a growing Chinese anti-access capability that includes ballistic missiles, and it makes sense for us to be aware of our ally\u2019s priorities. But that doesn\u2019t mean a big investment is required in this specialist area. Other parts of the ADF force structure (not least, submarines) also represent valuable alliance contributions, and a sizeable expenditure on BMD would have opportunity costs for the ADF and for the US as well.<\/p>\n

With a continued modest investment in BMD research and development efforts, and a watchful eye on defensive technologies as they mature, Australia will be well placed to adopt them in the future, should externalities make that desirable.<\/p>\n
