P-8b-2 Supersonic Flying Wing

As I love flying wings I thought I'd built a flying wing in besiege. This is a fictional, supersonic speed exceeding flying wing. It is quite stable in all directions which is usually a common flaw in flying wing designs.
It has retractable landing gear, a detailed cockpit and a aerodynamic body shape. The wings can withstand a hard turn while flying over 800 km/h. It also has trims which allows it to fly perfectly straight when flying at high speeds.
