Japanese site (in simulated/automatic translator English!) with details of the Kawasaki P-1 (radar, sonobuoy processor, illustrated with 8xASM-1E, etc ... Is the only site where I've finded the approximative wing area), and some notes of humour with the P-1 speculative variants painted in RAF or Japanese 1942 styles:

The text says the HPS-106 is very similar to the modelled APY-10.

Including details about rare Japanese weapons, as modern deep charges:

The text says the HPS-106 is very similar to the modelled APY-10.

 

The reference to how the HPS-106 and the AN/APY-10 works is in regards to the modes of search (Track While Scan, Synthetic Aperature, Moving Target Mode, etc.) The HPS-106 is not in the same category as the AN/APS-137(V)10 AKA the AN/APY-10 radar.

 

Other than that little bit I find this Microsoft Flight Simulator site to be chock full of good information on Japanese aircraft. I have bookmarked it and thanks for sharing it!
