When I was in Okinawa in the late 60s It was fun watching the U2s and Sr-71 take off. One time I timed a Sr-71 From the time he went to full afterburner to start his takeoff to out of sight (clear day) was 70 sec. Yes the F-16 can accelerate strait up. I built F-16s and F-22 and F/A-35s. Our test pilot for the F-16 use to do the full power climb to altitude on the first flight. I asked him about that one time and he said "you guys built it and said it was good to go. Besides if it breaks and I have to eject I am over the field and I don't have to walk home.
They would send a tanker up prior to take off. I clocked one taking to out of sight at around 90 seconds. Anyway-FAST!!!
The F-35 can take off vertically faster than the harrier. They like to use the little jump ramp to save fuel.
