Allenfort Air Base is seen in Ace Combat 04: Shattered Skies on the very first mission. Allenfort is stationed on the coast of Newfield Island, a base for some international passenger transport. During the Usean Continental War, it was an air force base protecting the City of Newfield. The air base was damaged during the Battle of Newfield Island by Erusian bombers who were attempting to bomb North Point, but because of an ISAF counter-attack, were forced to quickly drop their bombs on the air field, and return to base. Allenfort substained little damage on its facility, so the Erusians barely made any progress that day. Little is known about Allenfort's purpose in stationing a base here other than transportation and military protection on Newfield.
