High-resolution satellite images show that the construction of China's first full-size aircraft carrier is progressing steadily alongside expansive infrastructure work that analysts say suggests the ship will be the first of several large vessels produced at the site.

The images of the Jiangnan shipyard outside Shanghai were taken last month and provided to Reuters by the non-partisan Center for Strategic and International Studies (CSIS), building on satellite photos it obtained in April and September last year.

Noting a series of pre-fabricated sections, bulkheads and other components stacked nearby, CSIS analysts say the hull should be finished within 12 months, after which it is likely to be moved to a newly created harbor and wharf before being fitted out.
