It was precisely because of its bulkiness that the "Attack-8" was disliked by the Navy and failed to become a ship-borne attack aircraft, and the Navy could only let the "Attack-5" continue in service.
In fact, it was also key to the Air Force's decision to use the "Attack-8" to develop Electronic Attack Aircraft.
With a larger tonnage, it could carry enough electronic warfare equipment without significantly affecting flying performance, acquiring a sufficiently strong electronic warfare capability.
Of course, this also had a lot to do with the poor miniaturization of electronic equipment.
With its large tonnage, as well as an equally rare large internal bomb bay among attack aircraft, the "Attack-8FZ" could carry about 6 tons of electronic equipment without using external pylons, and by virtue of its relatively high speed, it could perform combat missions alongside attack aircraft.
