The Chinese navy , once generally limited to coastal operations, has developed rapidly under President Xi Jinping's ambitious military modernization.
It commissioned 18 ships in 2016, including missile destroyers, corvettes and guided missile frigates, according to state media.
Barely a week goes by without an announcement of some new piece of equipment, including an electronic reconnaissance ship put into service in January.
Still, the PLA Navy significantly lags the United States, which operates 10 aircraft carriers to China's one, the Soviet-era Liaoning.
Xu Guangyu, a retired major general in the People's Liberation Army now senior adviser to the government-run China Arms Control and Disarmament Association, said China was keenly aware of the U.S. ability to project power at sea.
"It's like a marathon and we're falling behind. We need to step on the gas," Xu said.
Trump has vowed to increase the U.S. Navy to 350 ships from the current 290 as part of "one of the "greatest military buildups in American history", a move aides say is needed to counter China's rise as a military power.
"We’ve known this is a 15-20 year project and every year they get closer to being a blue-water navy with global aspirations," said a U.S. administration official, speaking on the condition of anonymity.
"What you have seen this last year and what I think you will see with the new budget is that they are moving ahead with the short-term goal of being the premier naval force in the South China Sea and the East China Sea, with the mid-term goal, of extending all the way to the Indian Ocean."
In January, China appointed new navy chief, Shen Jinlong, to lead that push.
Shen has enjoyed a meteoric rise and is close to Xi, diplomatic and leadership sources say.
"The navy has gotten very lucky with Shen," said a Chinese official close to the military, speaking on condition of anonymity. "Now they know for certain their support goes all the way to the top."
Recent PLA Navy missions have included visits to Gulf states, where the United States has traditionally protected sea lanes, and to the South China Sea, Indian Ocean and Western Pacific, in what the state-run website StrongChina called Shen's "first show of force against the United States, Japan and Taiwan".
Last month, a Chinese submarine docked at a port in Malaysia's Sabah state, which lies on the South China Sea, only the second confirmed visit of a Chinese submarine to a foreign port, according to state media.
The submarine had come from supporting anti-piracy operations off the coast of Somalia, where China has been learning valuable lessons about overseas naval operations since 2008.
Chinese warships have also been calling at ports in Pakistan, Bangladesh and Myanmar, unnerving regional rival India.
"It's power projection," said a Beijing-based Western diplomat, of China's navy.
