China's shipbuilders are teasing a new coast guard 'mothership,' and there's talk it could be an aircraft or drone carrier

• A state-owned Chinese shipbuilder said it's debuted the design of a "mothership" for its coast guard.
• Military bloggers in China speculate that it might be an aircraft carrier or a drone platform for the high seas.
• If so, it would be an unprecedented asset for a law enforcement agency, though Japan is also planning one.

In early August, military bloggers started buzzing about a small detail on a Chinese shipbuilder's social media.
