Team Bath Drones is a University of Bath student engineering team founded in 2014 that designs, builds and flies autonomous aircraft for the IMechE UAS Challenge. It placed second overall in 2024 and won the 2025 competition, including the Scrutineering and Sustainability Awards. Its 2025 SULIS aircraft used a flax-fibre composite structure, a V-tail and lifting fuselage, with a 3 kg parachute-delivered payload at 10 kg maximum takeoff mass. The team describes BLUEFIN as its 2026 competition aircraft under development, providing experience in aircraft manufacturing, autonomy and systems integration.
