China’s navy has a new problem: not enough names for its rapidly growing fleet of warships.“China is running out of provincial capitals to name new destroyers, and it might have to turn to other big domestic cities, which reflects the country's rapid naval development in recent years,” according to Chinese newspaper Global Times.The People’s Liberation Army Navy recently named its first Type 055 destroyer the Nanchang, which is the capital city of East China's Jiangxi Province.One of the three other Type 055 destroyers will be named Lhasa, the capital of Southwest China's Tibet Autonomous Region, according to Chinese media. That just leaves Nanning and Taipei as the names of provincial capitals for destroyers (Taipei is Taiwan’s capital, though Taiwan has not yet declared independence as a separate nation from China).Which means non-capital cities will have to bequeath their names to Chinese destroyers. The latest destroyer is named Qiqihar, which is a non-capital city in in Northeast China's Heilongjiang Province. A few ships have been named after major cities, such as the Shenzen, a Type 051 destroyer.“Chinese destroyers and frigates should be named after big and medium Chinese cities, according to the naval vessels naming regulation,” Global Times said. “This means naming of destroyers does not necessarily have to use provincial capitals, as it was a non-binding tradition.”
