The original Hornet, now flown mainly by Finland, Switzerland and Spain. Live F/A-18 Hornet positions.
No F/A-18 Hornet 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.
The legacy Hornet has largely left American service but remains the front-line fighter for several European air forces, and those are the aircraft most likely to appear here. Finland and Switzerland in particular fly in busy shared airspace where transponder use is expected, so their Hornets transmit more consistently than most fighters anywhere.
Both of those fleets are on their way out. Finland is replacing its Hornets with the F-35A and Switzerland has ordered the same, so this page is documenting a type in its final years in Europe.
Spain, Kuwait and Malaysia are the other significant operators. The US Marine Corps still flies a diminishing number of F/A-18C and D aircraft.
Finland, Switzerland, Spain, Kuwait and Malaysia, plus a shrinking US Marine Corps fleet. Canada and Australia have retired theirs.
Both operate in dense civil airspace where ADS-B is expected for peacetime flying. It is a rule about airspace rather than anything about the aircraft.
The F-35A in both Finland and Switzerland. Spain is moving toward the Eurofighter and a future European design.
