In our case, we have a mixed defence industrial base. This enables us to do some elements of systems integration and produce high-level radar capability indigenously, and that is now featured on a number of our warships, but we have tended to go to the U.S. for combat systems and weapons systems. For example, our torpedo is actually a joint Australia-U.S. Mk 48 torpedo.
The real challenge for Australian industry is how to integrate all of these capabilities onto one platform. In the case of a submarine, for example, the new submarine, a French design, will have American weapons systems integrated in Australia. That's quite a challenging task.
Where our industry needs to be really strong at the high-tech end is in those integration capabilities, rather than in the weapons system design, for which we're quite happy to go overseas.
