The engine nozzles, plus the single TCS mount in the nose (as opposed to the dual TSC/IRST mount in the F-14D) give this particular Tomcat away as an F-14B, rather than an “A” (although it might have been one of the initial upgrades under the F-14A+ program).
Personally, I would have put the digital radar in all the aircraft and left the old Pratt motors in the rest of the jets. It would have cost half as much and we could have done the whole fleet. The compressor stall/spin issue in the A was almost matched by the AB burn through explosion issues in the GE engine.
