BEIJING, Sept. 20 -- Recently, a base under the PLA Naval Aviation University organized a live-fire shooting exercise for J-15 fighter jets over the shore of Bohai Bay. According to a carrier-based aircraft flight instructor of the university, this exercise was a very intense one with several rounds of jets dispatched. And the complex weather conditions had made it much more difficult for the pilots to aim, shoot and drop bombs. The training has tested the pilots' ability to fire ammunitions in actual combat scenarios, verified the performance of weapons and equipment, and accumulated valuable experience for follow-up training.
