This model is in 1/700 scale. The aircraft are unarmed. The 12x Supermarine Swift Mk 5 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 Swift was a British single-seat jet fighter of the Royal Air Force (RAF), built by Supermarine during the 1950s. After a protracted development period, the Swift entered service as an interceptor, but, due to a spate of accidents, its service life was short. A photo reconnaissance variant resolved some of the Swift's teething problems."
