This study analyzes the effectiveness of an optical camouflage method called counterillumination and its effectiveness on an unmanned aerial vehicle (UAV). Counterillumination is achieved by emitting blue light on the bottom of the UAV to blend into the sky. Preliminary results are underwhelming, but design modifications can be made to improve the performance of the system. Further testing is required in order to collect any relevant data. Due to the COVID-19 Pandemic, unfortunately, this project could not be completed.Lew Wentz FoundationMechanical and Aerospace Engineerin
