Casse Aerospace was a spacecraft manufacturer that operated from 2599 to 2623. Founded by noted ship designer and former Roberts Space Industries (RSI) engineer Leonard Casse, it released its first ship in 2604, the limited-run Cosmo Sloop. Due to the ongoing Second Tevarin War (2603 - 2610), the leisure craft's sales were lower than projected, and Casse made the decision to pivot his designs from civilian to military. The 2607 Hurricane fighter saw success in the latter years of the war. After the conflict ended, the company accepted a contract from the United Empire of Earth (UEE) government to create a long-range patrol ship, but all work ceased when Casse passed away in 2615 after an in-air collision. The board sold the company to an investment firm in 2620, and closed its doors. In 2784, J. Harris Arnold of Anvil Aerospace purchased Casse Aerospace's portfolio in response to a copyright infringement lawsuit for allegedly stealing elements of Casse's designs. Today, Anvil utilizes Casse's signature elements of curved wings and an open circle signet in many of its ships.
