Yeah, and the rest is for propulsion. I’m guessing it probably has several backup hydraulic systems. I can’t imagine the hydraulics needed to manipulate the flap, rudder, aileron,……….. at +3 Mach. Another amazing thing is the amount of fuel capacity and still go that fast. Watched a video about it and the cockpits are pretty tight. There’s not the visibility that one would want or expect.
