Report: China has secret nuclear sub base

BEIJING, May 1 (UPI) -- China has built a major secret underground nuclear submarine base, intelligence shows.

Displaying satellite imagery it has obtained, The Daily Telegraph shows a harbor it says can house several nuclear ballistic subs and aircraft carriers.

Other images show numerous moored warships and underground tunnels at the Sanya base on the southern tip of Hainan island.

The report said the Pentagon is more concerned with massive tunnel entrances that could lead to caverns in which up to 20 nuclear subs could be hidden from spy satellites.

The report says the United States estimates China will have five 094 nuclear subs operational by 2010.
