Dredging up long ago memories, cost (including estimated through life costs) and the extant design requirement ruled out the modified FFG option, remembering that at the time we were just discovering the cracks. What was known as the T23 light was knocked out on cost. M vs Meko was a very tight contest, came down to the more minor issues like the fact that the Meko looked more upgradable, and was more easily able to accomodate the Mk 45; and comparative cost for what you got. You have to remember that the Anzac was in those days supposed to be a cheap and cheerful patrol frigate; indeed it was called a Tier 2 or maybe even Tier 3, it’s a bit hazy, at the time (things that go around come around). As I say, that’s my memory but it was more than 35 years ago, and I was a Commander who was on one part of the evaluation, not a senior member of the team.
