One of the greatest interceptor fighters used by Legiones Astartes during Great Crusade and Horus Heresy was Primaris Lightning. It was a fast maneuverable aircraft capable of delivering overwhelming firepower. While it wasn’t extremely durable, it was piloted by skillful space marine legionaries capable of extreme evasive maneuvers. After those events Lightning jetplanes were mostly abandoned by Space Marine chapters, and their new pattern (which isn’t performing as well as heresy-era ones) is used almost exclusively by Imperial Navy
