The Blacksword Missile is a deadly type of ordnance utilised exclusively by the Dark Angels Space Marine Chapter's elite 2nd Company, known as the Ravenwing and the Successor Chapters of the Unforgiven. The Blacksword Missile is designed to fit under the wings of the deadly aircraft known as the Nephilim Jetfighter. These missiles take their name from the ominous black contrails they leave in their wake, and are used primarily to bring down enemy flyers and light ground vehicles.
