The TA-4J is a dedicated trainer version based on A-4F, but lacking weapons systems, and with down-rated engine, 277 built new, and most TA-4Fs were later converted to this configuration. A refinement of A-4E with wing-top spoilers to reduce landing roll out, nose wheel steering, and more powerful J52-P-8A engine with 9,300 lbs of thrust. 147 built.
The A-4 Skyhawk, in the two-seat TA-4J configuration, was introduced to a training role replacing the TF-9J Cougar. The TA-4J served as the advanced jet trainer in white and orange markings for decades until being replaced by the T-45 Goshawk. Additional TA-4Js were assigned to Instrument Training RAGs at all the Navy master jet bases under RCVW-12 and RCVW-4. -[Wikipedia]
