There were stories all over the Internet, some of them even well-documented, about the guy in New Zealand who built his own cruise missile. The government decided to take it away from him. Students in the Engineering faculty next door to me at university build UAVs. At the end of each year students put up posters about the work they've been doing. One group put cameras on the UAV, low-light ones IIRC, for tracking wildlife. Another group had done a feasibility study of launching air-to-ground missiles from it! Battle tanks are a bit harder, sure. But if Israel and Sweden can build their own, Australia could probably manage. The big-iron items, warships and high performance jets, seem likely to remain restricted to major industrial powers. Unlike everything else, they are becoming more and more expensive and difficult to make. And the do-it-yourself UAVs and cruise missiles rely on high performance CPUs which have become incredibly difficult to manufacture. There's only about four or five foundries in the world that could build a Pentium 4 chip, and they cost billions of dollars to set up. Yet just about anyone can obtain one if they have a few hundred $US. Extrapolating to GZG, I imagine ship hulls and engines to be fabulously expensive and valuable, so never ever get junked. Old NAC/ESU/FSE/NSL hulls end up being sold to lesser powers, where they are extensively refitted with new electronics and software. Most of the budget in such navies probably goes to welding the hulls back together when they start to leak too much. cheers,
