The military Sealift Command ocean surveillance ship USNS Impeccable is seen underway on Monday, March 9, 2009.
The United States maintains that the unarmed USNS Impeccable was operating legally in international waters when it was surrounded and harassed by the Chinese. Beijing responded hotly to a U.S. protest over Sunday's incident, and neither nation is backing down, even as they prepare for a much-anticipated first meeting between President Barack Obama and Chinese President Hu Jintao next month.
Although they would not be specific about the Impeccable's mission when it was intercepted by the Chinese ships, two defense officials said the ship is designed and equipped for sub-hunting work and was part of a calculated U.S. surveillance operation in the disputed South China Sea.
Comment: Wow, a somewhat different perspective from the bluster displayed in this article about the same event. Seems the US were not squeaky clean after all, spying on Chinese submarines in Chinese waters.
