After months of internal debate within the Obama administration, the guided missile destroyer USS Lassen transited within 12 nautical miles of Subi Reef, one of China’s artificially-built features in the South China Sea, on October 27 in what is termed a “freedom of navigation” (FON) operation. It was accompanied by two maritime surveillance aircraft, a P-8A Poseidon and a P-3 Orion.
