Open-source maritime and aerial tracking data has been revealed. U.S. naval and air assets appear to be shadowing Russian warships that passed Florida’s eastern coast on their way to make port in Cuba. Open-source intelligence analysts on Tuesday posted updates showing the CG Stone coastguard vessel, the USS Truxtun and USS Donald Cook destroyers, and a Royal Canadian Navy frigate travelling south down the Florida coast, following the Russian ships headed to Cuba. Above them, at least one U.S. Navy P-8A Poseidon and Canadian CP-140 Aurora appeared to be conducting surveillance.
