Upon takeoff from ZZZ; lost all hydraulic fluid and pressure. Opted for landing at [nearby airport] due to a longer runway. Landed uneventfully. Was noted a nose gear hydraulic line had ruptured and mx is looking into the issue.
I was acting as the pilot in command of a CE-680 on an FAA Part 135 charter. We had picked up four passengers in ZZZ. At 400 feet AGL I called to the second in command for 'gear up'. I immediately heard a loud noise and felt a vibration under my feet when the landing gear handle was selected up. As the gear handle was raised we were alerted to 3 messages on the EICAS telling us that we had low hydraulic pressure on the left and right engines as well as low hydraulic volume. We also got an almost immediate value of '0' displayed on our hydraulic quantity indicator. We notified ATC immediately and made them aware of our situation and requested time to go through our checklists. After completing the appropriate checklists; briefing the passengers and evaluating our situation we determined that it was in the best interest of safety to get the airplane on the ground as soon as possible. We determined that we needed to land at an airport with a longer runway than what ZZZ had to offer since our breaking would be severely limited. ZZZ1 was the closest most suitable alternative so we informed ATC that that was our intention. We were given radar vectors for the ILS and made a successful landing and were able to clear the runway on a high speed taxiway using emergency braking. We were then towed in to [FBO] at ZZZ1 without any further issues. Upon exiting the airplane we immediately noticed an orange fluid streaming down both sides of the aircraft and its belly emanating from the nose gear wheel well. Upon inspection of the nose gear wheel well we discovered what appeared to be a ruptured hydraulic line. The aircraft is now currently parked at [FBO] in ZZZ1 awaiting inspection and maintenance.
CE-680 experiences a loss of hydraulic fluid and pressure upon gear retraction at takeoff. Crew elects to divert to a nearby airport with longer runways. Upon landing crew notes hydraulic fluid streaming from the front wheel aft towards the belly.
