No. 115 Squadron (CXV Squadron) currently serves as a vital training unit based at RAF Wittering, functioning as the Grob Tutor T1 Operational Conversion Unit (OCU) for No. 1 Flying Training School. Its primary mission is to train Qualified Flying Instructors (QFIs) who will go on to teach the next generation of RAF pilots. Formed in 1917, the squadron has a distinguished heritage as a heavy bomber unit, most notably during World War II, where it operated Vickers Wellingtons and Avro Lancasters and was one of the first units to trial the "Gee" navigation system. Its badge features a palm tree—a reference to its re-formation in 1937 after service in the Middle East—and its motto, Despite the Elements, pays tribute to the perilous weather conditions and hostile skies its crews faced during night bombing campaigns.
