China's first home-built carrier sets out for sea trials
China's first domestically developed aircraft carrier left its northeastern port to begin sea trials on Sunday, state media said, the latest milestone in the country's efforts to modernise its military.
The still-unnamed carrier was launched this time last year but since then has been undergoing fitting of weapons and other systems and has not yet entered service.
[...] "Our country's second aircraft carrier set sail from its dock in the Dalian shipyard for relevant waters to conduct a sea trial mission, mainly to inspect and verify the reliability and stability of mechanical systems and other equipment," Xinhua said.
"A sea trial is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a "shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days."

The land-based version of the US system works on artillery shells and mortars.
The US system sends out its own radar. The incoming trouble can be radio-silent and it won't matter. China's system also does optical tracking.
