This model is in 1/700 scale. The aircraft are unarmed. The 6x Mikoyan MiG-31 (Firefox) 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 MiG-31 NATO reporting name "Firefox", is a fictional aircraft appearing in Craig Thomas' novels Firefox and Firefox Down, as well as the Clint Eastwood film based on the former.
The Firefox is an interceptor aircraft with stealth capabilities, to the point that it is invisible to radar. It is powered by two incredibly powerful "Turmansky" turbojet engines that permit flight at hypersonic speeds, but their exhaust gives the Firefox a prominent infrared signature. The Firefox's most famous feature is its Thought-Controlled Weapons System, which uses signals from the pilot's brain to target enemies and fire weapons; however, it only responds to commands thought in Russian. The Firefox's weapons consist of up to four air-to-air missiles (modified for thought guidance), two cannons, and four Rear Defense Pods on the wings, which fire explosive charges at a pursuing aircraft or missiles."
