🇨🇦🇮🇱 About an hour ago #RCAF CC-130J Hercules 130603 #C2B53F fell victim to Israeli GNSS/GPS spoofing & jamming. 130603's transponder ceased transmitting accurate position data, then stopped transmitting position data at all.

Image It is unclear if flight #CFC2503 is air-dropping relief to Gaza, or transiting near #Israel.

It is clear that Israel is not pausing their months long electronic warfare attack on all civilian and military aviation in line of sight, and the media doesn't want to mention it.

🇨🇦⚓️ Where #HMCSMontréal has been since March 26, when they departed Halifax on #OpPROJECTION, using @MarineTraffic AIS-T and AIS-S data. 🧵

This thread serves as a guide, to you the reader, of what to look for in Royal Canadian Navy communications; it's your crackerjack box secret decoder ring when they're vague.

All of this information has been broadcast by the ship's AIS transponder over the airwaves, picked up with every SIGINT satellite in orbit, military and commercial, every plane in line-of-sight(LOS), collected by every significant adversary, and included in a dossier with other intelligence, that was reported up their chain of command, before I woke up this morning.

Our military and government public affairs officials can, without compromising national security, speak plainly and include everything up to (at least) this level of information, because every adversary already knows; they told them. They got the memo.

This is also the minimum amount of detail that the public should expect in any media story about HMCS Montréal's deployment; all this information is at journalists' fingertips too. Public affairs should be more forthright to make journalists' lives easier. This information isn't a secret to the outside world.

All times in UTC, unless otherwise mentioned.
🇨🇦⚓️ Royal Canadian Navy Halifax-class multi-role patrol frigate #HMCSMontréal's first port of call was Lisbon for 4 days from April 4 to April 8.

Fighting erupted in Sudan on April 15. #OpPROJECTION

🇬🇧 41% (9) of the RAF A400M Atlas fleet of 22 do not fly. Of the remaining 59% (13) that do fly, some of them are deployable, and some are homebodies doing training and certification. #ZM406 returned from the Airbus depot in Getafe, Spain 🇪🇸. Image 🇬🇧 RAF C-130J Hercules #ZH869 #43C198 was sent to Cambridge 🇬🇧 to be decommissioned, bringing the number of Hercs remaining to 5, all of which are flying regularly, except #ZH870 #43C04C hasn't flown in a week.. maybe they're next? 🪦
+ No coverage of the Herc flight to Benghazi. Image

Hasn't anyone thought about the implications of what the government admits to doing?

"China promptly issued a protest on Monday after a US Navy P-8A Poseidon reconnaissance plane flew through the Taiwan Strait"

Monday, their time, is still 2023-02-27, ie today.

Did anyone already identify which #USNavy Boeing P-8A Poseidon that was this morning? Very likely, yes. 👇

Are you familiar with how MLAT works? I have a dataviz/infographic/GIS visualisation challenge that I'm coming to the realization I do not have the skills to adequately convey in a graphic, and am looking for some help. Basically, I'd like to show what Syria (say) would look like with a robust MLAT-gathering network of Mode-S receivers in an isometric 3D representation, showing overlapping coverage cones, and the density of receivers needed for border or nationwide MLAT, if that makes any sense.

‣ 177703 flew the 3rd shipment of armoured vehicles to #Haiti 🇭🇹
‣ 177703 flew supplies from #14WingGreenwood to Sicily 🇮🇹 for the pair of CP-140 Auroras deployed to Ex #DynamicManta.

🇺🇸 Has anyone looked up the Mode-S of the #USNavy P-8 Poseidon used in this piece, and put together the timeline of this story yet? Mike is on the case, zeroing in on the time, which is what I needed! 😎

Very interesting; if I'm not mistaken the #AusAirForce changed their emissions posture vis-a-vis their transponder between their 2020 and 2021 #OpARGOS missions. In 2020, either they didn't fly, or they obfuscated their patrols sufficiently to avoid open source scrutiny. From 2020-09-22 to 2020-10-24 🇦🇺 #RAAF P-8A Poseidon A47-010 #7CF9D4 was deployed on #OpARGOS, but they were never picked up using ADS-B flying any missions over the East China sea, only transits between bases. 🤔

Some git that moderates the @flightradar24 subreddit censored easily accessible publicly available information. 🤦‍♂️ I'm going to need to tweet a lot more about the E-4, again, to raise awareness of their baseline, clearly! 🤦‍♂️

Before I explain to the #AusAirForce 🇦🇺 comms ppl, please appreciate that their P-8A Poseidon fleet broadcasts its own location to anyone who will listen, using ADS-B. That signal will geolocate them from orbit. On patrol, their locations are the least secret thing over the SCS. This tweet, that has all the words in it you'd need to find it, gives you the tail numbers and ICAO Mode-S hexes of the whole #AusAirForce 🇦🇺 P-8A Poseidon fleet. You can follow them pretty much any day with the link that's included in the quoted tweet.

Here's a way you may not have looked at the data #ADSBexchange gives you.

Planes using ADS-B transmit their precise location (lat/lon/alt/speed/etc) but planes using Mode-S need to be geolocated using multilateration (MLAT). like TRIangulation, but with 4 data points (Multi) 🧵 Here is an image (and link) representing *only* planes being geolocated using MLAT. Meaning, 4 or more #ADSBexchange receivers have them in line-of-sight (LOS); 10 of them.

Gripe:
The CAF display poor situational awareness re public visibility of 🇨🇦 #RCAF aircraft.

Examples:
- #14WingGreenwood deployments to Keflavik
- #19WingComox #OpCARIBBE Jan/Feb 2023
- #CANSOFCOM ISR over #Ottawa Jan 27/28 2022
- Withdrawal x2 CC-130J from #OpIMPACT Aug 2022 What about #14WingGreenwood deployments to Keflavik?

It's only a matter of time before the CP-140 Aurora deployments to Keflavik, that coincide with Russian Navy movements through the GIUK gap, get traction in the press.

They pretend it's not happening. We see them. 🤦‍♂️

🇺🇸 People stop me on the street all the time and ask me, Stef, how can you tell where in the United States there are too few #ADSBexchange receivers to geolocate aircraft that aren't broadcasting their precise location data using multilateration (#MLAT)?
Great question! Here's what you do:
filter by altitude, between 10,000-40,000 ft, that restricts the results to aircraft which are flying high enough that we should home four or more receivers are in line of sight, a requirement for #MLAT.

Let me understand this really well, 🇺🇸🇨🇦 #NORAD QRA fighters didn't shoot down the 🇨🇳 Chinese spy balloon in American, then Canadian, then American airspace? 😂

YOU HAD ONE JOB.

🤦‍♂️ They flew right through the #ADIZ that the media get their bloomers in a bunch about when the Russians fly antiques through, and VIOLATED American and Canadian airspace, which the Russians never do, and the Chinese continue to do; did I get that right? What a bunch of bullsh!t.

🇨🇦 Here's the distribution of the Canadian-registered Top Aces Alpha Jet fleet. I took the superset of everything registered to them, worked back to 2022-09-01, identified everything that's flown in that time, and flagged those that haven't flown in a month+. Image 🇨🇦 CFB Cold Lake (4)
🇨🇦 CFB Bagotville (5)
🇨🇦 Halifax (1)
🇩🇪 Fliegerhorst Nordholz (2)
(+5 haven't flown in over a month)

The idea is, if they haven't flown in over a month, they may be going through some maintenance; or not, I can't tell. 🤷‍♂️

While this article is 5 years old, and likely out of date regarding the operations that are being carried out from Keflavik 🇮🇸, it makes it clear to me that the "rotational" deployments of large numbers of #USNavy P-8A Poseidon and #RCAF CP-140 Aurora aircraft are a #NATO mission It's also clear that #RCAF and #USNavy operations out of NAS Keflavik 🇮🇸 and NAS Sigonella 🇮🇹 are related, it's basically the same mission, the only difference is #Keflavik surges when the Russian Navy is brining a submarine through the GIUK gap, making a very obvious tell for us
