    F-35 Stealth Aircraft Goes “Live” On Flight Tracking Websites As It Flies Mission Over Israel

    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.

    Noteworthy, the F-35 used a US hex code (AF351F, first logged on Nov. 15, 2016 over at Live ModeS and since then regularly tracked in the US) even though it’s safe to believe it could be one of the Adir aircraft delivered to the Israeli Air Force in the last weeks. A hex code is a unique ICAO 24-bit address assigned to a Mode-S/ADS-B transponder.

    According to Mil ModeS logs possible tailcode was 13-5067, even though this should be an F-35A that last June, based on the photographs available online, was assigned to the 6th Weapons Squadron, assigned to the USAF Weapons School, at Nellis Air Force Base, Nevada. Anyway, the F-35 flying over Israel yesterday did not broadcast its position via ADS-B but it could be tracked by means of Multilateration (MLAT). Using Time Difference of Arrival (TDOA) MLAT measures the difference in time to receive the signal from four different receivers, to geolocate and track an aircraft even if it does not transmit ADS-B data.

    As we have widely explained here at The Aviationist (read here for a complete analysis):

    The ADS-B system uses a special transponder that autonomously broadcasts data from the aircraft’s on-board navigation systems about its GPS-calculated position, altitude and flight path. This information is transmitted on 1090 MHz frequency: ground stations, other nearby aircraft as well as commercial off-the-shelf receivers available on the market as well as home-built ones, tuned on the same frequency, can receive and process this data.

    Flightradar24 and PlaneFinder rely on a network of several hundred (if not thousand) feeders who receive and share Automatic Dependent Surveillance-Broadcast (ADS-B) transponders data and contribute growing the network and cover most of the planet.

    Obviously, only ADS-B equipped aircraft flying within the coverage area of the network are visible.

    Actually, in those areas where coverage is provided by several different ground stations, the position can be calculated also for those planes that do not broadcast their ADS-B data by means of Multilateration (MLAT). […]

    Although the majority of the aircraft you’ll be able to track using a browser (or smartphone’s app) using the above mentioned Web-based tracking services are civil airliners and business jets, military aircraft are also equipped with Mode-S ADS-B-capable transponders: a 2010 Federal Aviation Administration rule requires all military aircraft to be equipped with ADS-B transponders by Jan. 1, 2020, as part of its program to modernize the air transportation system.

    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.

    As Israel made first operational use of David's Sling missile defense system 2day at two SS-21 Syrian ballistic missiles, another 1st occured: new F35 went fully visible (still w u.s trnspd AF351F) on @flightradar24@cencio4 @CivMilAir @AnshelPfeffer

    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?

    Here’s what we have been observing for some 7 years:

    […] during the opening stages of the Libya Air War in 2011 some of the combat aircraft involved in the air campaign forgot/failed to switch off their mode-S or ADS-B transponder, and were clearly trackable on FR.24 or PF.net. And despite pilots all around the world know the above mentioned flight tracking websites very well, transponders remain turned on during real operations, making their aircraft clearly visible to anyone with a browser and an Internet connection. As a consequence, we have been highlighting the the risk of Internet-based flight tracking of aircraft flying war missions for years. In 2014 we discovered that a U.S. plane possibly supporting ground troops in Afghanistan acting as an advanced communication relay can be regularly tracked as it circled over the Ghazni Province. Back then we explained that the only presence of the aircraft over a sensitive target could expose an imminent air strike, jeopardizing an entire operations. US Air Force C-32Bs (a military version of the Boeing 757 operated by the Department of Homeland Security and US Foreign Emergency Support Team to deploy US teams and special forces in response to terrorist attacks), American and Russian “doomsday planes”, tanker aircraft and even the Air Force One, along with several other combat planes can be tracked every now and then on both FR24.com and PF.net.

    So, what’s your take on this? The “F-35 visible over Israel” was a deliberate action or a mistake? Let us know in the comments section.

    I think that's transponder disclosing fighter's position, not radar ID. Don't be misled.

    The F35 don't have and no need ADS-B transponders

    As part of its modernization efforts, the FAA has issued a rule that requires all aircraft—military and civilian—operating within US national airspace to be equipped with Automatic Dependent Surveillance-Broadcast (ADS-B) Out transponders, which broadcast its position via satellite, by January 1, 2020.

    https://nationalinterest.org/blog/how-the-f-22-f-35-could-lose-their-stealth-thanks-the-24350

    “During the initial days of the conflict, F-35s occasionally return to their bases - only to discover several are heavily damaged from enemy missile attacks,” Harrigian and Marosko write, in their warplay. Those F-35s must divert to civilian airfields. By this time, the F-22 and F-35 won’t need air traffic controllers as their high-tech computers will guide them to runways, even in bad weather.

    We can track the aircraft without ADS-B transponders


    Aircraft without ADS-B transponders do not broadcast their latitude/longitude, so FlightAware uses multilateration of 1090 MHz Mode S transponder signals to determine the aircraft's location by using time difference of arrival (TDOA) when an aircraft is detected across four or more receivers/ground stations.

    https://flightaware.com/adsb/mlat/

    Secondary surveillance radar ( SSR ) [1] is a radar system used in air traffic control (ATC), that not only detects and measures the position of aircraft, ie bearing and distance, but also requests ad***ional information from the aircraft itself such as its identity and altitude.

    This system, which became known in civil use as secondary surveillance radar (SSR), or in the USA as the air traffic control radar beacon system (ATCRBS), relies on a piece of equipment aboard the aircraft known as a " transponder ." The transponder is a radio receiver and transmitter pair which receives on 1030 MHz and transmits on 1090 MHz

    https://en.wikipedia.org/wiki/Secondary_surveillance_radar

    Flightradar24 aggregates data from three sources:[4]

    1. Automatic dependent surveillance-broadcast (ADS-B). The principal source is a large number of ground-based ADS-B receivers, which collect data from any aircraft in their local area that are equipped with an ADS-B transponder and feed this data to the internet in real time. The aircraft-based transponders use the GPS and other flight data input to transmit signals containing aircraft registration, position, altitude, velocity and other flight data. Currently, about 65% of aircraft in Europe are equipped with ADS-B but only 35% in the US. For example: all Airbus aircraft are ADS-B equipped but Boeing 707, 717, 727, 737-200, 747-100, 747-200, 747SP do not come equipped and are not generally visible unless retrofitted by their operators. Typical ADS-B receivers include Kinetic Avonics′s SBS-1 and AirNav-systems's AirNav and these receivers are run by volunteers, mostly aviation enthusiasts. ADS-B signals can also be received and uploaded by a low-cost Software-defined radio, such as those based on the $15 R820T tuner.[5]
    2. Multilateration (MLAT). The second major source is multilateration using Flightradar24 (FR24) receivers. All aircraft types will be visible in areas covered by MLAT, even without ADS-B, but while 99% of Europe is covered, only parts of the US are. At least four receivers are needed to calculate the position of an aircraft.[4]
    3. Federal Aviation Administration. The shortfall in the US is mostly made up from 5 minute delayed data from the Federal Aviation Administration (FAA) but this may not include aircraft registration and other information.

    Why are you sure it does not happen? Theaviationist.com is a reputable source, not a tabloid

    Aaaahhh...I see another dreamer who thinks he has a way to defeat the American 'stealth' fighters. I can see him not reading his sources and not bothering to do basic research.

    Yeah could just be them informing the presence of F-35 with Luneberg Lense and that's how they have the label on the aircraft, IF they tracked it using radar, they'd be tracking the signature enhanced aircraft. How else can a radar know the exact aircraft. Sorry that's not how radars work. It's very difficult to positively identify a VLO aircraft and conclude it is XYZ.

    They do have such transponders and there is no way they could have identified the plane otherwise.

    If radars could detect the F-35 in such ease those Lebanese radars would have detected the F-35 when it flew over Beirut.
