Megaships being built in Shanghai

Massive vessels, the biggest in world, will be able to carry 23,000 containers

China is building the world's largest container ships, each of which will be able to carry more than 23,000 standard containers, which together can hold, for example, more than 1 billion units of the Apple iPhone X.

The construction of the first two megaships started in late July. They're being built by Jiangnan Shipyard Group and Hudong-Zhonghua Shipbuilding Group, both of Shanghai, according to China State Shipbuilding Corp, a State-owned giant that owns the two companies.
