Zhang Dingfa

As commander, Zhang initiated steps to reform the PLA Navy in the aftermath of the Ming 361 accident, including reorganizing the chain of command to improve accountability for maintenance and emphasizing training for more realistic scenarios. After serving for three years, however, Zhang was forced to step down in August 2006 because of terminal cancer. He was replaced by Admiral Wu Shengli, who continued his reforms.

On 14 December 2006, Zhang Dingfa died in Beijing. President Hu Jintao and Vice President Zeng Qinghong were among those who attended his funeral. He was cremated and buried at the Babaoshan Revolutionary Cemetery.

Zhang became the PLA Navy commander in the aftermath of the fatal submarine 361 accident in 2003. He initiated reforms to improve maintenance and training of the naval force, but stepped down three years later because of cancer, and died soon afterwards.

Following a fatal accident with the Type 035 Ming-class submarine 361 in April 2003, Admiral Shi Yunsheng was removed from his position as Commander of the PLA Navy. Zhang Dingfa was chosen as his replacement partly because of his background as a career submariner, in an era when the PLA Navy was relying on its submarines in the event of a possible conflict with the United States over the Taiwan Strait issue. In September 2004, he was promoted to the rank of admiral, and became a member of the Central Military Commission (CMC). He was the first naval commander to become a CMC member.

In November 2002, Zhang was appointed president of the PLA Academy of Military Science, the first naval officer to hold the position.

In August 1985, Zhang became chief of staff of the Qingdao Naval Base of the PLAN's North Sea Fleet, and he attained the rank of rear admiral in June 1991. He was then promoted to chief of staff of the North Sea Fleet in 1993, deputy commander in 1995, and commander of the North Sea Fleet and concurrently deputy commander of the Jinan Military Region in 1996. He became a vice admiral in July 1998, and a deputy commander of the PLA Navy in December 2000.

After graduating from the Submarine Academy in July 1964, Zhang joined the PLAN's submarine force, and participated in the development of China's nuclear submarines. He became a deputy submarine commander in 1971, and commander in 1975.
