text_A: The USN operated the F4H-1 (re-designated F-4A in 1962) with J79-GE-2 and -2A engines of 16,100 ;lbf (71.62 ;kN) thrust and later builds receiving -8 engines. A total of 45 F-4As were built and due to the rigors of combat, none survived in a condition necessary for use as test or training aircraft. The USN and USMC received the first definitive Phantom, the F-4B which was equipped with the Westinghouse APQ-72 radar (pulse only), a Texas Instruments AAA-4 Infrared search and track pod under the nose, an AN/AJB-3 bombing system and powered by J79-GE-8,-8A and -8B engines of 10,900 ;lbf (48.5 ;kN) dry and 16,950 ;lbf (75.4 ;kN) afterburner (reheat) with the first flight on 25 March 1961. 649 F-4Bs were built with deliveries beginning in 1961 and VF-121 Pacemakers receiving the first examples at NAS Miramar.
text_B: If a Navy pilot were to give his F-4A fighter an affectionate nickname, would he be more likely to choose something like "A is for Angel" in reference to the fact that the jet got him home safely from a potentially-deadly battle, rather than a semi-facetious "A for Effort"
YES.
