Bai Zhizhan, during his visit to the "Huai River" class, was given a special introduction to the radio proximity fuzed shells by the shipyard's technicians.
In order to test this new type of ammunition, the Empire's Navy had already converted a long-range cruiser, equipped with 130mm and 80mm high-altitude guns, into a test ship. The main modification was to adapt the high-altitude guns to be able to fire radio proximity shells directly.
As for the test targets, they were remote-controlled airplanes.
The results indicated that the main value of radio proximity shells lay in long-range interception.
Simply put, when engagement distances were between 5 and 15 kilometers, radio proximity shells could intercept incoming enemy aircraft more effectively. The biggest advantage this brought was that it forced enemy aircraft to disperse before entering attack range, thus preventing them from launching organized attacks on carriers.
