Harrington was the pilot of a PBY Catalina (callsign Hammerhead). He and his PBY helped destroy a Japanese merchant fleet on its way to Okinawa. He was flying to a destroyed US fleet with the other PBY (callsign Mantaray). Unfortunately, he, his plane, and the crew were attacked by at least five Japanese A6M Zeros and their engine caught fire and exploded, destroying the plane's right wing and killing Harrington and his crew. The plane then crashed into the ocean. He was probably friends with Booth. He is never seen in-game. At the beginning of "Black Cats", the player can see one of his crewmen at the left gun.
