No. 120 Squadron (CXX Squadron), currently stationed at RAF Lossiemouth in Scotland, is a premier maritime patrol unit operating the Boeing Poseidon MRA1. Re-formed in 2019 to usher in a new era of anti-submarine warfare, the squadron is responsible for protecting the UK’s nuclear deterrent and critical undersea infrastructure by tracking hostile submarines in the North Atlantic. Formed in 1918, it quickly became the RAF’s top-scoring anti-submarine unit of World War II, famously sinking 14 U-boats while flying the Liberator from bases in Iceland and Northern Ireland. Its badge features an Icelandic Falcon perched on a rock, symbolizing its vigilant watch over the northern seas. This relentless pursuit is captured in its motto, Endurance, a quality that defined its exhausting long-range patrols during the Battle of the Atlantic and continues to define its missions today.
