Includes two resin GAM-67 Skybolt Missiles with pylons designed to fit the Airfix Avro Vulcan kit. The Airfix kit as supplied includes Olympus 301 tailpipes, the proposed engine variant that was due to go into service carrying the Skybolt ALBM, prior to its cancellation in 1962. If you wish to built the Vulcan which actually flew with Skybolt missiles for trials (early production XH537), this will be the subject of a future release, this set allows you to build the Skybolt carrying Vulcan, had it gone into service.
