Print this article Since at least Monday, United States Navy aircraft, British sea and air forces, and French anti-submarine aircraft have been engaged in unusual operations in and around waters proximate to the location of this week's G-7 summit. I have highlighted the relevant waters in the context of this week's G-7 summit at Carbis Bay in Cornwall, England. The summit begins on Friday and ends on Sunday. Google Maps The unusual deployments and the G-7 summit's proximate location beg a question: Is Russia operating a submarine in these waters? NATO activity certainly lends to that prospect. On Monday, a French air force surveillance Beechcraft Super King Air 350 was in the area, and a U.S. P-8 Poseidon aircraft operated off the northern Cornish coast. The U.S. P-8 then transited to Europe. On Tuesday, a British (either Royal Air Force or Royal Navy Fleet Air Arm) Super King 350 was operating in the area.
