Maybe the T26 is probably the best option for the longer term, but I think the current Government is in a bit of a 'Catch 22' position, in my opinion anyway.
Not wanting to sound too political, but it's now seven years (June 2007) since the Howard Government announced the selection of the 3 AWD's and 2 LHD's, and since that time not one ship has been ordered from an Australian yard, nil, zero, zip!
During the six years of the Rudd/Gillard/Rudd Governments nothing happened.
When the 2009 DWP was produced the possibility of the 4th AWD was still an option, and there was the announcement of the class of 20 OCV's, but by the time the 2013 DWP was released, the 4th AWD had disappeared and the 20 OCV's disappeared way into the distance (gone forever?) and of course there was still no decision on the replacements for Success and Sirius either.
So maybe if the 4th AWD had been ordered, way back when, these discussions of the suitability, or not, of a modified AWD hull for the Future Frigates wouldn't even be an issue or being discussed.
Maybe if Federal Labor and the SA State Labor Governments had poured some money into Techport, eg, enlarged the shiplift, increased the hard stand areas, more fabrication sheds, etc, there could have been the possibility (probably remote) that the replacements for Success and Sirius could now be under construction and block work spread around the other yards (but now because of the tight time frame for entry into service, those two ships will be built O/S) and those enlarged facilities could have also come into use when Choules is eventually replaced too.
And of course there are (or where) the 20 OCV's too.
So as I said, that's the Catch 22 I see the Government finding itself in, does it investigate (as it is now doing), the possibility of modifying the AWD hull for the Future Frigate so that block work can start sooner rather than later to keep naval shipbuilding (and jobs) going, or does it wait much longer till the first UK T26 hits the water (I think the first is to commission in 2021), see how it performs and then start construction of an Australian version of the T26?
Are there other alternatives, or solutions, to keep industry going till the Future Frigates (as per the original time table) and Collins replacements start construction?
The 20 Pacific Patrol Boats would supply some work (but I don't know the planned start date or how stretched out the construction period is intended to be), there is of course the replacements for the LCH fleet and the very remote possibility that the OCV's could end up back on the table too.
Obviously till we see the 2015 DWP (and the DCP too), all those questions (and answers) will still be up in the air!!
Cheers,
