Trivia

 * The Drone Fighter was originally going to be featured in Halo 3 under the name "F99 Wombat", but didn't appear until Halo 3: ODST. It was featured in the Art of Halo 3 book. It wasn't actually officially named the Wombat, but was just a joke referring to the fighter's designation.
 * The vehicle also appears as a silhouette on a nearby ship in Longshore.
