Anvil Aerospace is a spacecraft manufacturing corporation headquartered on Terra (Terra III). Founded in SEY 2772 by spacecraft designer J. Harris Arnnold, it produces both military and civilian crafts. Anvil's earliest ship, the Osprey, was directly inspired by the work of the renowned ship designer Leonard Casse, who perished in a mid-air collision in SEY 2615. Casse's signature curves and circles are incorporated into the silhouettes of most Anvil ships. The F7 Hornet and the F8 Lightning are among the Anvil spacecraft currently produced for all branches of the United Empire of Earth (UEE) military.
