Let's talk about American weapons and how Europe has to wean itself off them.
Part 1 of a long thread; this one looking at fighter jets.

First and foremost: Europe has to get all American made components out of all weapon systems produced in Europe. If Trump can shut down a
1/24 Image
European production line by withholding a component, then that component has to replaced... and if that is impossible, then that weapon system has no future and production has to end.
As for the F-35... Europe has nothing even close in combat capability. Best course will be
2/n Image
to see the existing deals through and then focus on acquiring Eurofighters and Rafales, both of which are way more capable than whatever junk russia sends up in the air.

The main issue will be that the Rafale's production line is running already at full capacity, while the
3/n Image
Eurofighter Eurofighter assembly lines in the UK, Italy, Germany and Spain should in theory be able to triple output to 60 fighters per year, but there are many uncertainties as the stinginess of European governments led to the Spanish & German lines being suspended in 2018.
4/n
At least the assembly line in Germany was restarted in 2023... at a very low rate.

As for the Gripen: it's dead. Sweden being stingy in 2012 and opting for US made GE F414-GE-39E engines instead of further developing the Swedish made RM12EF engine means that the Gripen E
5/n Image
either has to switch engine (costly) or production will end once the last Gripen E comes of the production line in Linköping... or when Trump suspends engine deliveries.

For the future: Europe needs to focus on getting the British/Japanese/Italian Global Combat Air Programme
6/n Image
(GCAP) into service ASAP.
The competing French/German/Spanish Future Combat Air System (FCAS) will come years later... if at all.
As for fighter weapons: almost every European air force has its depots full of US made AIM-120 AMRAAM and AIM-9 Sidewinder air-to-air missiles...
7/n
and i.e. Sweden and Germany are currently buying 1,219 AIM-120C-8 missiles for $3.5 billion... even though Europe produces the Meteor missile, which is better than the AIM-120C-8.

As said before: see the current deals through but then buy European missiles only.
8/n Image
Image
This means that European air forces have to buy Meteor (or the cheaper/less range French MICA NG RF) when they need a radar guided beyond-visual-range air-to-air missile; and buy the German IRIS-T, British ASRAAM or French MICA NG IR when they need an infrared homing missile.
9/n Image
As for anti-ship missiles:

🇫🇷 Exocet AM39 B2.2 (for Rafale)
🇸🇪 RBS 15 Mk.4 Air (for Gripen; photo)

There are also other options... but they use an American engine:
🇮🇹 Marte ER (🇺🇸 Williams WR WJ-24-8G)
🇳🇴 Joint Strike Missile (🇺🇸 Williams F‐415)

In both cases it should be
10/n Image
possible to replace the American engines with the French Microturbo TRI-40, which is used in the aforementioned Exocet and the Norwegian surface-launched Naval Strike Missile (which was the basis for the development of the air-launched Joint Strike Missile).
The RBS 15 uses
11/n
a French made Microturbo TRI 60 engine, which is also used in the British/French SCALP/Storm Shadow cruise missile.
The German Taurus uses a Williams P8300-15 engine... which means it needs to be redesigned.
As for air-to-surface missiles and bombs... it's not looking good.
12/n Image
The British Brimstone initially used an American made Orbital ATK rocket engine; AFAIK the newer Brimstone 2 uses a French made engine.
However the newest British air-to-surface missile, the SPEAR 3, uses an American Pratt & Whitney TJ-150 engine...
13/n Image
When it comes to guidance kits for bombs almost everyone in Europe uses the American made Paveway or JDAM kits.
Only European made option are the French AASM Hammer kits. But even the AASM uses the American controlled GPS.
Europe licence produces Paveway and JDAM kits, but
14/n Image
long term Europe has to only produce European guidance kits, which then also use Galileo PRS instead of GPS.

As for targeting pods: most European air forces bought the Israeli Litening, but again the French developed their own system: first the Damocles and now the TALIOS.
15/n Image
TALIOS is cutting edge and so far only compatible with the Rafale, but European air forces should consider adding it to the Eurofighter.

Where Europe has nothing to compete with the US are SEAD (Suppression of Enemy Air Defenses) systems.
The key weapon system for this
16/n
mission are anti-radiation missiles... the UK developed and produced such a missile, namely the ALARM, but in 2013 it was taken out of service.

Ukraine received older American AGM-88 HARM missiles, which were essential to push back russian ground based air defence systems.
17/n Image
Europe not only does not longer produce its own anti-radiation missiles, its most modern fighters can't even use them. (15 German Eurofighters will get the ability to use AGM-88E Advanced Anti-Radiation Guided Missile by 2030)
As russia deploys a massive number of ground
18/n
based air defence systems like the S-400, S-300, Buk, Pantsir, etc. Europe needs produce its own anti-radiation missile and mount it on more fighters, as currently 85% of NATO SEAD aircraft are provided by the US Air Force (Italy and Germany maintain 13 respectively 21
19/n Image
outdated Tornado ECR fighters for the SEAD mission; while the US Air Force has 200+ F-16CM/DM Block 50 fighters).
Yes, European air forces also plan to use the AGM-88G AARGM-ER with their F-35A... but that is an American missile on an American fighter; and having a locally
20/n Image
produced missile is better for Europe's defence capabilities, for Europe's industry, and for Europe's future.
I did not dive into avionik systems, as Europe can produce all of them... it's just a question of will to remove US systems. Overall Europe can defend itself against
21/n
russia, but that will require: no more US components to secure production lines in war time from American sabotage and investing a LOT more into developing, producing and buying European systems.
Europe can do it, if European politicians stop deluding themselves that the US
22/n
will be a trustworthy partner again once Trump is gone... a) he will die in office no matter what the term limits are and b) after him the regime will "vote" into power someone worse (Vance? Trump jr?).
So: be more French Europe and start developing/buying European only!
23/n
Next up: aircraft (transport, tanker, etc.), then helicopters, then naval systems, land systems, etc. etc.

Lots of things to do, but Europe can do it!

The 11th Airborne Division is the least likely to be used to invade #Greenland.
The division's deputy commander is Canadian. He is responsible for Operations. The 11th would have to arrest part of their own officers, before being able to plan a Greenland invasion.
Also

there are just 8 C-17 Globemaster aircraft at Elmendorf Air Force Base. The USAF would need to fly a dozen more up to Alaska, which of course Canada would notice. Then to reach Greenland the C-17 would have to cross Canada's North, which NORAD's Canadian officers would report

to the Canadian and Danish governments.

It is much more likely the US will inform allies that a brigade of the 82nd Airborne Division at Fort Bragg will fly to the Middle East, which means the air route will take them right over Greenland. And at Fort Bragg you also have the

This is a typical clown tweet by someone, who knows nothing about WWII.

3 years before D-Day, the Soviets & nazis were in a love-feast, while the US had not entered the war; & when it did it had to cross an ocean full of nazi submarines to stage troops & materiel for D-Day.
1/14
And unlike the warmongering Soviets, which in June 1941 fielded 304 divisions, the US Army fielded just 37 divisions when Japan attacked Pearl Harbor (+ two Marine Corps divisions).
Before any D-Day the US Army had to start forming new divisions (38 in 1942 and 17 in 1943) &

then ship those divisions across the Atlantic, which was teeming with German subs, while the Soviets just used trains to bring troops and materiel to the front (& if the Soviet had had to ship troops across an ocean, they would have just accepted that a third of their troops

The @RoyalAirForce - once the strongest air force in Western Europe... but now...

7 Eurofighter Typhoon squadrons are expected to fulfill the tasks, for which 35 years ago the RAF fielded 40 squadrons (31 active & 4 reserve + 5 shadow squadrons, which would have been formed
1/27 Image
from the personnel & fighters of the RAF's operational conversion units).

At the end of the Cold War these 40 squadrons were assigned to 4 commands, each with a specific mission & enough aircraft to fulfill their mission.

No. 1 Group was tasked with striking Soviet forces
2/27 Image
in Northern Germany, including with WE.177 tactical nukes.

The Group fielded 8 active, 4 reserve and 2 shadow squadrons, which flew Tornado GR1, Jaguar GR1A, and Harrier GR5 fighters (the reserve squadrons flew Hawk T1A). The group also included the RAF's 3 aerial

I was asked to talk about Austria's Armed Forces... which is a bit boring, because surprisingly their armed forces get so much right.

Yes, the Austrians are some of the worst sanctions ignorers when it comes to russia, and they host the biggest russian signals intelligence

Anyway, unlike the other neutral EU member (an island that spends GDP-wise less on its armed forces than the Vatican), Austria has a proper air force and a proper army; both of

Italy has ordered its first KF41 Lynx infantry fighting vehicles... but there is a twist.

As the Italian Army is in a rush to ready its forces to battle invading russians in the Baltics (& Finland), the first 5 × KF41 will arrive within weeks in the Hungarian configuration.
1/8 Image
That means there won't be any Italianization of the first 5 × KF41. The Italian Army feels that it can't wait for that. Training has to start ASAP.

Therefore these 5 × KF41 will come with Rheinmetall's Lance Turret with 30mm MK30-2/ABM autocannon. Along with these KF41 Italy
2/8 Image
will receive training and simulation systems to begin training troops ASAP.

This order also includes 16 × KF41 in a hybrid version: the chassis will come from the Hungarian production line, but these KF41 will receive Leonardo's Hitfist turret with Leonardo's 30mm X-Gun.

I am relaxed about the US ending the rotation of a light brigade through Romania.

Yes, it is bad optics and russia will use it for its propaganda, BUT two armored brigades, a combat aviation brigade, a division artillery, a division sustainment brigade, and a division HQ
1/4 Image
continue to rotate to Poland and the Baltics.

Right now the:
• 3rd Infantry Division HQ (arrived in Poland 4 days ago - photo)
• 1st Armored Brigade, 1st Infantry Division
• 3rd Armored Brigade, 1st Cavalry Division
• 3rd Division Artillery
• 3rd Combat Aviation Brigade
2/4 Image
are in Poland and the Baltics.

Ending the rotation of a light brigade to Romania is a far less bad than ending the rotation of the armored brigades. It is also understandable as the US Army's light divisions (10th Mountain, 25th Infantry, 82nd Airborne, 101st Airborne) are
