The most-produced stealth fighter, and one you will almost never see on a tracker. Here is why, and what does appear.
No F-35 Lightning II is transmitting ADS-B at the moment.
Military aircraft are not obliged to broadcast, so this happens regularly. The count refreshes every thirty seconds.
Nothing of this type is up right now.
More than a thousand F-35s have been built and around twenty countries have ordered it, which makes the near-permanent zero on this page a fair question. The answer is that a stealth aircraft has an obvious reason not to broadcast its position, and its operators do not.
What does occasionally appear is European. The Netherlands, Norway, Denmark, Italy and the United Kingdom fly in airspace where transponder use is expected for routine transits, and a delivery flight or a transatlantic ferry will often be visible for part of the way.
Three variants share the name: the F-35A for conventional runways, the F-35B that can land vertically, and the carrier-capable F-35C. All three report the same designator here.
Because a stealth aircraft transmitting its position defeats much of its purpose, and operators keep ADS-B off outside routine transits. When you do see one, it is usually a ferry flight or a delivery.
Runway requirements. The A is conventional, the B has a lift fan for short takeoff and vertical landing, and the C has a bigger wing and stronger structure for carrier operations.
Around twenty, including the United States, United Kingdom, Italy, Netherlands, Norway, Denmark, Israel, Japan, South Korea, Australia, Finland, Switzerland, Poland, Belgium and Germany.
