I agree for Navantia, the obvious, known and existing features are there but we still don't know whether they have changed the propulsion system to be more in line with modern ASW practice. Sonar outfit, ship ASW weapons are still not knownHave to agree with Assail, none of the contenders are showing their hands in public.
But I think Navantia is a bit of an exception to the rule, whilst we don't know the finite details of their proposal, we do know that they are clearly basing the F5000 on the AWD, which is already a 'known' entity in the Australian environment, unlike the other two contenders.
Anyway, the guessing game continues, and will no doubt continue until we have an announcement.
I still feel that if the building schedule and ship system commonality are to be achieved Navantia must be the favourite. All three ships are close enough in capability that these other factors above will be the determining factor.......and political self interest, naturally.
