"Despite significant efforts to improve P-8A intelligence, surveillance, and reconnaissance (ISR) sensors, overall P-8A ISR mission capabilities remain limited by sensor performance shortfalls."
Slightly concerning?
The Navy did not complete the planned Multi-Static Active Coherent (MAC) wide area ASW search sensor testing during the ECP 2 OT&E period due to submarine target unavailability. As a result, OPTEVFOR submitted a separate operational test plan to complete remaining MAC ASW test events during future operational test periods.
My understanding is that there is a real shortage of coherent (as opposed to impulsive) active buoys, and that the failure to complete MAC testing is as much down to this as to the lack of targets. Either way, it's clear that MAC - the baseline capability underpinning the claimed superiority of the P-8 in the ASW role, remains unavailable.
High Altitude ASW Weapon Capability (HAAWC) testing remains incomplete, too. How does the P-8A manage to engage targets from FL nosebleed without it?
