Aquila (previously 'Condor') is the second stage of Griffin 1, CUSFs first attempt to cross the Karman line. It is powered by a Cesaroni Pro-98 motor, has a bistable fin system, and is equipped with a hypersonic recovery system. CUSF intend to launch Aquila for testing of the recovery system in 2022.


Griffin 1 was conceived in early 2020, but specific work on Aquila did not begin until early 2021, when Barty Wardell was appointed Aquila PM after the March 2021 AGM. Following his appointment, there was a period of very rapid development of the Aquila aero in April 2021, partially based off of Martlet 4, but the stability had to be 2 directional due to the nature of the recovery system. After this period of rapid design at the end of April, development has slowed for exam season, with only some design review and documentation taking place over summer.
