Aegis Vanguard

The Vanguard Warden is a deep space fighter created by Aegis Dynamics for the United Empire of Earth Navy (UEEN). Its base model is a twin-engine, multi-crew ship designed to perform long-duration missions that would otherwise be outside the reach of shorter-range fighters. Though it is less maneuverable than other Navy spacecraft like the Hornet, it is capable of taking more damage and carrying more munitions. Other variants of the Vanguard include the Harbinger fighter-bomber, the Sentinel electronic warfare platform, and the Hoplite dropship. A hard-charging bulldog of a fighter that features extensive forward-mounted weaponry designed to tear through the shields and armor of other spacecraft. So-named because their multiple-jump range allows them to form the vanguard of any military expedition, Vanguards have seen extensive service against the Vanduul.
Here is a short history of publications about the series from the RSI website, CIG has not actually made a dedicated cinematic for any of the Vanguards so the following are closely related videos.
