The article mentioned above is incorrect: the radar in question, the
AN/APY-10 is NOT an AESA antenna.

The APY-10 is a deravitive of the APS-137, both use a parabolic dish.

JSTARS is a passive ESA system.

I thought the APs-137 sat in the nose of the P-3, while the APY-10 is
the
improved version slated for the P-8.

The LSRS on the other hand, is a different radar that uses the large
"canoe"
radome mounted under the P-3's fuselage.

At least that's my understanding of the situation. If I'm wrong, feel
free
to correct me.
