Bonza, Cheers for your points, Thoe as far as my understanding is, The 25mm Typhoons are used for defence against asymmetric threats, Such as small boats. So there got defence against boats packed with explosives, Still dont see any defence against aircraft.
And realistically, A light plane can still make a reasonable distance, And the Canberra class assault ship would have to operate with in reasonable range of the coast, Due to there LCM's.
I just find it highly irrispnsible of those in the power to fix the lack of defences on the Canberra's, These days plenty of misle boats that can hit targets 50-70km away, Mass firing of missiles, And the defensive weapons of a single AWD will have an impossible time of defending just its self, Let alone a Canberra.
And just to calrrify your second point, I advocate getting more destroyers, As in my personnal beliefe, The RAN needs them, But only after such times as the Canberras are fitted with proper defensive weapons and radar. Once thats done then go for getting more AWD's.
Now onto reading the RAN thread =) Cheers
No worries mate, it's a good thread and if you check back through the Navy thread archives there's quite a few bits and pieces about the Canberras from the last few years. Very instructive to read what some of the professionals have to say!
As far as the Typhoons go, I think they'd do fine against a light plane. Granted it'd be pretty close-in defence - but I imagine a naval task force (and it's important to remember the LHDs aren't going to operate in a vacuum, and as such capability should be measured against an integrated force, not necessarily individual units) would have assigned a response to a light plane long before it got within ramming distance.
Anti-ship missiles are prolific, as you say, but in what constitutes a high threat environment (and I imagine the presence of AShMs would qualify) there would be quite a bit of "preparation" of the battlespace done before the LHD entered. What are the likely threat environments where an Australian LHD is going to face a massed firing of anti-ship missiles? And in that environment, is it likely an LHD is going to be committed without sufficient support to respond to such threats?
Remember to look at the whole picture, not just the ship itself and not just the capability of an escort by itself. Look at the threat environment, look at the likely response as an integrated force and then consider the capability as a whole. And consider it from the perspective of the ADF as a whole, not just the RAN (as in a high threat environment the other branches will absolutely be involved).
For example, how likely is it to face a massed firing of anti-ship missiles from the 50-70km range bracket when you have RAAF air support (Wedgetail, Super Hornet, etc), submarines on ISR, possibly inserted special forces providing additional observation of the enemy (which the SAS have done in the past and do very well), and so on.
Now I know the scenario above has a lot of "ifs" in it, and that the support granted by such a force would be situational and bound by limitations of platform range, circumstance and so on. But the question is, is the RAN going to commit an LHD to an environment where they can't provide the above support (or similar, it's just an example), or are they going to approach the situation with alternative strategies that will ensure the LHD is placed at minimum risk?
The threat environment must be considered, as you say, but what also must be considered is how the LHD is intended to be used and supported within that environment.
As I said the above is just an example so I welcome corrections on behalf of other posters, but I think in the context of an integrated force, a light plane isn't going to get close to an LHD. Nor do I think an LHD would be deployed within range of hostile anti-ship missiles without sufficient support to defeat those missiles. No one is going to be more aware of the Canberra's individual defence deficiencies more than the RAN. As such I believe they are confident in the overall capability afforded by their force mix to use the ships in the roles for which they're intended.
