RP - Basically that mix, plus Saab 2000 (faster than C295, a mini-P-3), with the EriEye as a companion for both wide-area maritime surveillance and AEW.
Boeing is now making a run at Joint STARS replacement with the 737-700 and an aft-mounted radar canoe (P-8A/AAS is heavy) and still has the idea of replacing all C-135/707-like ISR with the 737. Who knows, in the spirit of their love affair with Saab they might stick the EriEye next-gen (gallium-nitride) radar on the 737... I really don't know how well the NGC radar on Wedgetail works after all the fixes.
