AN/APQ-140 was a multifunction radar operating in J-Band, developed by Raytheon and intended for the B-1 Lancer supersonic strategic bomber. The prototype was tested in a KC-135 with an enlarged nose radome. It used a passive, radiation-fed phased-array antenna (reflection type) with a diameter of about 70 cm and 3 300 phase-shift elements. However, for cost reasons, in B-1 Lancer, various radars developed from the AN/APQ-66 were used instead in the initial production phases. The AN/APQ-164 was then finally used.
