This model is in 1/700 scale. The aircraft are unarmed. The 12x Supermarine Attacker F.1 aircraft are connected as a single sprue by a wire under the body of the aircraft. Once the wires are cut the model does not require finishing.
According to Wikipedia: "The Supermarine Attacker was a British single-seat naval jet fighter built by Supermarine for the Royal Navy's Fleet Air Arm (FAA). It was the FAA's first jet fighter. Last 11 production F 1s were built as FB 1s plus an additional aircraft ordered on 27 March 1951 to replace one aircraft destroyed on a production test flight. The FB1 had been modified from the original design to allow it to carry rocket projectiles or bombs under the wings."
