There, Carver's stealth ship sends a sea drill into the Devonshire and steals one of the ship's missiles. Then Carver's goons shoot down a chinese J-7 fighter and the survivors of the Devonshire using Chinese weapons, causing tension between the two nations, which each believing the other attacked them.
When looking through the sound files of Carver's satelite launch event, Gupta hears Bond talking to Carver's wife. When he shows Carver the footage, Carver decides to have his wife killed by Dr. Kaufman.
While infiltrating Carver's agency at Hamburg, Bond sneaks into Gupta's bureau and opens his safe, finding the GPS encoder inside and returning it back to the American military
