No. 202 Squadron (CCII Squadron), currently stationed at RAF Valley in Wales, serves as the "Maritime and Mountains Training Squadron" within No. 1 Flying Training School. Operating the Airbus Jupiter HT1, it is tasked with the specialized instruction of helicopter aircrew, teaching them the complex techniques required to operate safely over the sea and in challenging mountainous terrain. Formed in 1914 as a Royal Naval Air Service unit before joining the RAF in 1918, the squadron has a deep maritime heritage, having flown flying boats like the Catalina and Sunderland on long-range patrols during World War II. However, it is perhaps best remembered by the British public for its decades of service as a premier Search and Rescue (SAR) unit, where its iconic yellow Sea Kings saved countless lives. Its badge features a Mallard alighting on water, and its motto, Semper Vigilate ("Be always vigilant"), remains a testament to its watchful history.
