thumb|An McDonnell Douglas F/A-18 Hornet|F/A-18 taking off from an [[aircraft carrier]] thumb|An Embraer E175 taking off Takeoff or take-off is the phase of flight during which an aerial vehicle leaves the ground and becomes airborne. For space vehicles that launch vertically, this is known as liftoff.
For fixed-wing aircraft that take off horizontally (conventional takeoff), this usually involves an accelerating ground run (known as the roll) on a runway to build up speed so the wings can generate enough lift. For aerostats (balloons and airships), helicopters, tiltrotors (e.g. the V-22 Osprey) and thrust-vectoring STOVL fixed-wing aircraft (e.g. the Harrier jump jet and F-35B), a helipad/STOLport is sufficient and no runway is needed.
