Tourist,
People who argue the case for an MPA based on "SAR" are delusional.
Don't think you will find many in the maritime world who argue for an MPA based on SAR. What you will find is those who argue for an MPA for the ASW/ASuW/ISR reasons with the 'bonus' of being able to conduct SAROPs somewhere down the line in the mission set.
Betty,
There is presently NO long range SAR asset. The end..
Yes there is. They are called ships.
But I'm sure you meant to say No long range airborne SAR asset....
