You doubt the AAS is powerful based on what? Don't perhaps.
Hey I can make a scenario to. Realistic, another submarine or aircraft can follow the arsenal ship and provide info for torpedoes or missile guidance from P-8.

The
Advanced Airborne Sensor (
AAS) is a multifunction
radar installed on the
P-8 Poseidon maritime patrol aircraft. The radar is built by
Raytheon as a follow-on to their
AN/APS-149 Littoral Surveillance Radar System (
LSRS).
The AAS has its roots in the highly classified AN/APS-149 LSRS, which was designed to provide multi-function moving target detection and tracking and high resolution ground mapping at standoff ranges covering land,
littoral, and water areas. The radar was deployed on a small number of
P-3C Orions, with "game changing" results. Containing a double-sided
AESA radar with near 360-degree coverage, it could scan, map, track, and classify targets, and do all of these tasks near simultaneously; it was reportedly sensitive enough to pick up a formation of people moving over open terrain.

Building upon the LSRS, the AAS also has a double-sided AESA radar, which contains a
moving target indicator (MTI) that can detect, classify, and track targets on land and at sea at the same time, with
synthetic aperture radar (SAR) and
inverse synthetic aperture radar (ISAR) for picture-like radar imagery of both inland and ocean areas at the same time; these can profile vessels from a long distance and generate fine resolution without relying on optical sensors, especially in day or night and in adverse weather conditions. Once it detects and classifies a hostile vessel, the P-8 can send targeting information to another armed platform and guide a networked weapon (e.g.
Tomahawk cruise missiles,
SLAM-ER,
JASSM,
LRASM,
SDB II) to it through a
data link. The AAS is in ways superior to the
AN/APY-7 used on the
U.S. Air Force's
E-8 Joint STARS, looking both port and starboard rather than just being side-looking. Other potential missions could include detecting and tracking low flying and stealthy
cruise missiles, communications relaying, and
electronic warfare as a standoff platform to penetrate contested airspace, since AESA radars are capable of radar jamming, producing fake targets, frying electronic components, and even
cyberwarfare.
