The MiG-31 is the replacement for the MiG-25 from which it was developed. It entered service in 1981 and is expected to remain in service until 2030. It has a powerful radar and is armed with a 23mm cannon and up to 8 air to air missiles. It also features an exceptional top speed (like the MiG-25) of around Mach 2.8 or over 1800mph. It has the capability to intercept small targets, such as cruise missiles as well as conventional aircraft at long or short ranges. In short it is a highly effective interceptor aircraft.
Trumpeter are a relatively new company to us in Western Europe. They are from China and are known for producing well engineered kits with a good level of detail. This particular kit looks very well detailed and should build into a very nice model. There are markings provided for 2 Russian aircraft and their is a decent amount of ordnance included in the kit.
