Could someone please identify what this yellow contraption being fitted on the P-8's nose is? It looks like no radar I've seen and if it is a radar why's it shaped so weird? About the only thing i can make out that the Korean text thinks its the APY-10 but then what's the radar that goes in the bulbous hump below the plane? Thanks in Advance

That would be the APY-10 Multi-Mission Maritime and Overland Surveillance Radar.

That yellow ball is the transmitter for the radar. It may not look what most of us think a radar should look like but it is.

I'm not sure what the hump is on the bottom of the aircraft.

But then

1) isn't that a complete waste of the 737's large nose aperture given that Physics dictates the bigger the array the more the signal throw?
2) this provides only 180 degree surveillance - who surveys the rear 180 degrees?
3) What's the hump on the belly?

I am no expert but the antenna is stabilised in pitch & roll, 25deg in roll and from what I can deterrmine the roll axis is off centre above the antenna so it requires room to swing.
A second consideration perhaps, as the APY-10 is a development of the APS-137 the size constraints of that system may have played a part.

Cheers

PS, A side note, I wonder when the Aust Govt is going to announce a purchase of some P-8 for the RAAF?

If your camera sends text messages, that could explain why your photos are rubbish!
