When I wrote that, I had no idea (and have no idea) what air support is available to the Phillipines Border patrol formations.
My understanding is that in the Australian context, JORN and Aerial Assets do the locating, with the Bay and Armidale class PB's providing the 'response',
*If* the Phillipines has aircraft patrolling their EEZ, whether helicoptor or light fixed wing, my thoughts were that given the fact that their issue seems to be mostly in the littoral, they could possibly get away with using the converted fishing boats as motherships for the RHIB's, which lets face it, can do 40+ knots quite easily with a decent engine on the back.
With the Cape class appearing to be quite similar in capability to the Armidale class it looks like BPC will be experiencing a step change in their capability as long as enough are procured to compensate for the probable removal of the Armidale class from their current taskings.
