The head of production for China's new J-15, dubbed by Chinese officials as the 'cradle of China's fighter jets' died of heart attack on Sunday while on duty, official media in Beijing reported.
"Mourn General Manager Luo Yang. Luo will be immortal," read the electronic signs at the gates of China's Shenyang Aircraft Corp (SAC), which developed the new aircraft said.
Luo, who headed the group which developed the aircraft, was also chairman and chief manager of the SAC.
"Luo experienced a sudden heart attack while participating in flight landing training for China's first aircraft carrier, the Liaoning, around noon on Sunday", state-run Xinhua news agency quoted official China Central Television (CCTV)report as saying.
A new J-15 fighter jet was used as part of the landing exercise.
Sunday's event was first for landing of the aircraft on the carrier as well as the debut for the new jet, which now has been identified as the aircraft to be used for China's new aircraft carriers to be developed in future.
In many ways it was a debut performance for J-15 too as China unveiled it only in the recent weeks.
Russians specialists said it closely resembled Su-33 and carried a Russian engine.
J-15 is capable of firing anti-ship, air-to-air and air-to-ground missiles and precision guided bombs, according a report in China.org.cn.
Military experts believe its capabilities are comparable to Russia's Sukhoi Su-33 and the US F/A-18 Hornet, it said.
