AN/APY-10
American multifunction radar
The AN/APY-10 is an American multifunction radar developed for the U.S. Navy's Boeing P-8 Poseidon maritime patrol and surveillance aircraft. AN/APY-10 is the latest descendant of a radar family originally developed by Texas Instruments, and now Raytheon after it acquired the radar business of TI, for Lockheed P-3 Orion, the predecessor of P-8.
The AN/APY-10 mechanically scanned radar is a development of Raytheon's AN/APS-149 radar. Compared to the AN/APS-137, it is smaller in size, lighter, and uses less power. The radar is optimized for maritime, littoral and overland surveillance.
The AN/APY-10 is able to provide high resolution radar images in both overland and water modes. Available modes include color weather, synthetic aperture radar (SAR), inverse synthetic aperture radar (ISAR), periscope detection, and navigation. ISAR mode is said to be capable of both detecting, imaging and classifying surface targets at long range using a variety of resolutions.
AN/APS-80
The AN/APS-80 is the first member of the radar family the AN/APY-10 directly descends from, and this first member of the family was installed on P-3A/B. AN/APS-80 is an analog radar with a peak power of 143 kW. The original AN/APS-80 produced a single 2.6 x 3.4° beam, but later version, AN/APS-80A produces two beams: a 3.6° pencil beam and an 18° fan beam. A unique feature pioneered by AN/APS-80 is that it adopts two antennas to provide 360° coverage, with one antenna in the nose, the other in the tail, under the magnetic anomaly detector (MAD).
This brief starts where responsible research should: with the source description of “AN/APY-10” as american multifunction radar. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as american multifunction radar. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Mar 5, 2026. The linked authority identifier is Q4652822. None of the 0 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
