So, of the three, there are more mine warfare modules, it is the one role they do which nothing else does, they are in production and with the ability to become mine warfare ships if need be. By default, the emphasis ends up on mine warfare.
Also, at times, in the current musings over our force structure, analysts (like Bryan Clark) have proposed that they all simply be given mine warfare modules, and relegated to just that job.
So, others more qualified than myself also stress their mine warfare aspect. Bill has seen them as auxilliaries, and if mine warfare is an auxiliary function, then I can agreen with that. So, yes...I stress their mine warfare task.
As to downplaying the other tasks, I don't need to do that. Everyone else seems to be doing a fine job of it. I have elaborated on their other abilities. They have both diesel and gas turbine engines, and they can be run at speeds other than 40 knots all the time, so your arguments about ship noise in the ASW role would be something I have the impression you miss.
And in a discussion of their surface warfare abilities, I pointed out their shallow draft gives them a unique advantage which you dismissively laughed at. Here is the article from which I made my claims. (Finally refound it.) :
Keep laughing. My message at this point is that these things are in production and entering fleet service. They will then prove themselves whatever anybody's opinion of them is.
