GK,
Where do I assume that the current P8 is the final version?
Why HAAWC? What is driving this?
GPS sonobuoys expected to cost $800 each!
Torpedoes with wings? Can the UK use Mk 54? We got rid of Mk 46 because they were deemed to be unsafe. The Mk 54 back end is essentially the same.
MAD satisfied by launching a UAV, which will probably be, unless there is a suitable ship or land based facility within range, on a one way journey.
Why have the Indians added another belly mounted radar and MAD to their version?
P8 fuel burn rate is 3-5 time the rate of others in the current options mix? Admittedly you can go further, quicker but that is not always an advantage.
