Jack-In-The-Box (ジャック·イン·ザ·ボックス, Jakku in za Bokkusu) is the twenty-second episode of the anime series, Full Metal Panic!
To discredit Mithril, Gauron uses the Tuatha de Danaan to attack the USS Bunker Hill (CG-52), which is patrolling just nearby. Using resonance, Tessa communicates to Kaname a plan to regain control of the submarine, then creates a diversion that allows Kaname to escape. Gauron's men pursue her, but Sousuke and Kurz arrive in time to help. Kalinin visits Bunker Hill to convince the U.S. Navy not to respond in force after Gauron fires two harpoons at the ship.
