    An F-35, most probably one of the Adir jets recently delivered to the Israeli Air Force, appears on Flightradar24.com: deliberate action or just a case of bad OPSEC?
    On Jul. 23, an F-35 went fully visible on popular flight tracking website Flightradar24.com as it performed a mission out of Nevatim airbase. The aircraft could be monitored for about 1 hour as it went “feet wet” (over the sea) north of Gaza then flew northbound to operate near Haifa.
    […]
    As for the reasons why the aircraft could be tracked online, there are various theories. The first one is that it was a deliberate action: considered the F-35 went “live” few hours Israel made first operational use of David’s Sling missile defense system against two SS-21 Syrian ballistic missiles, there is someone who believes the mission was part of a PSYOPS aimed at threatening Israel’s enemies (Syria in particular). Our readers will probably remember the weird, most probably bogus claim of an IAF F-35 mission into the Iranian airspace originally reported by the Al-Jarida newspaper, a Kuwaiti outlet often used to deliver Israeli propaganda/PSYOPS messages.

    However the Israeli Air Force has already made public the fact that the F-35 has been used in air strikes in the Middle East (Syria and another unspecified “front”) lately. On May 23, the Israeli Air Force Commander, Maj. Gen. Amikam Norkin said during a IAF conference attended by 20 commander of air forces from around the world: “The Adir planes are already operational and flying in operational missions. We are the first in the world to use the F-35 in operational activity”. He also showed a photograph of an “Adir” flying at high altitude off Beirut (with radar reflectors, hence not in “stealthy mode”). In other words, there’s probably no need to remind Syria or Iran that the Israeli Air Force has the F-35 since they are already using it in combat.

    For this reason, there is also someone who believes that the first appearance of an Israeli Adir on Flightradar24 may have been a simple mistake: the Mode-S transponder was not turned off. A case of OPSEC fail in one of the most secretive air arms in the world.

    Indeed, transponders are usually turned off during real operations as well as when conducting missions that need to remain invisible (at least to public flight tracking websites and commercial off the shelf receivers). Unless the transponder is turned on for a specific purpose: to let the world know they are there. In fact, as reported several times here, it’s difficult to say whether some aircraft that can be tracked online broadcast their position for everyone to see by accident or on purpose: increasingly, RC-135s and other strategic ISR platforms, including the Global Hawks, operate over highly sensitive regions, such as Ukraine or the Korean Peninsula, with the ADS-B and Mode-S turned on, so that even commercial off the shelf receivers (or public tracking websites) can monitor them. Is it a way to show the flag? Or just a mistake?
