The subject of this thread will be the electronic warfare history of the Battle of the Bulge.
This history is almost unknown in military history circles, let alone the public, because there have been exactly two articles on it in 75(+) years. 1/
STRATEGIC JAMMING IN PERSPECTIVE.
Long range jamming platforms have been the focus of air campaigns against integrated air defense system (IADS) since WW2. There have never been enough of them and their allocation is a strategic level concern in every war fought since 1945. 2/
The 8th Air Force's 36th Squadron was its heavy jamming unit. It supported 8th AF bomber streams forming up to attack German with VHF band barrage jamming to prevent the Luftwaffe hearing formation chatter & it had a jamming major role during the D-Day invasion of Normandy. 3/
Where the 36th HBS gets involved in the Ardennes involves ART-6 through ART-11 "Jackal" series communications jammers. The photo below shows one of a series of six jammers targeted against German tank radio traffic. 4/ aafradio.org/countermeasure…
The "American Jackal" jammer was a piece of kit that duplicated a British tank radio jammer used in the Western Desert to cover 8th Army in Wellington twin engine bombers.
Despite the highly classified nature of the 36th Jamming Sqd’s capabilities, their were liaison teams of the British Branch of the American MIT Radiation Laboratory (BBRL) all over North West Europe from two months before D-Day to the Ardennes offensive. 6/
Starting in April 1944 BBRL was briefing every senior US Army staff officer it could catch. The flag rank briefer was named John Trump, the uncle of Pres. Donald J. Trump. So Ninth and Third Army senior staff would have been well aware of the capabilities of 7/
...the British build Jostle and American built Jackal tank radio jammers in the 36th Squadron’s B-24’s.
The problem with this 36th HBS Jackal tank radio jamming capability was the 8th AF bomber generals hated it.
They didn't want to share B-24's penny packet with the Army. 8/
Spaatz, Doolittle etc wanted to pass this mission to Ninth AF medium bombers.
This wasn't practical for the simple reason training up & equipping a medium bomber sqd to the 36th's capability would take too long. 9/
Now that we have the context established, lets get to the meat of the 36thJamming Squadron's involvement with the Ardennes offensive.
Short form: Everyone in Allied high command knew where the German Ardennes offensive attack force was.
With one exception, everyone 10/
...thought it was a _DEFENSIVE_ counter-attack force waiting for an allied attack.
The sole exception being 1st Army's G-2 intelligence officer Colonel Benjamin "Monk" Dickson.
As Jörg Muth author of "Command Culture: Officer Education in the U.S. Army and the 11/
...German Armed Forces, 1901–1940" recently put it on the H-War e-mail list:
12/
The full story of Colonel Benjamin "Monk" Dickson's Intel report 37 has to await another Ardennes thread, but it gives context to US Ninth Army's G-2 not only identifying 6th Panzer Army's assembly area, but also convincing Lt. Gen. William Hood Simpson to request the 36th 13/
Heavy Bombardment Squadron (RCM) to fly sorties to jam their radios days before the attack.
A request which was "officially" denied by 8th Air Force because of the German IADS heavy Flak gun threat B-24 to jamming planes. 14/
This is how Maj. Richard Riccardelli's 1985 article "Electronic Warfare in WWII" described the process by which Ninth Army asked for and was denied jamming support. 15/
The word that jumps out is -staffing-. The Ninth Army request for jamming had to be well staffed to make it through the approval process to get to 8th AF & get rejected there on the grounds of vulnerability to German Flak gun concentrations in the proposed jamming orbit of 16/
...Sixth Panzer Army radio emitters.
This staff work for requesting the 36th Jamming Sqd's support was akin to a request asking for the Operation Cobra type carpet bombing and had to include as a minimum the following: 17/
So, to be clear, LTG Simpson & staff, General Bradley & Staff, General Eisenhower's SHAEF staff, and 8th AF all knew where the Sixth Panzer Army was and its capabilities.
LTG Simpson wanted to do something about it and was denied. 18/
After the German's attacked, things changed.
General Patton's 3rd Army asked for the 36th HBS (RCM) to provide support. The 36th flew jamming missions on the 28th & 31st of Dec 1944 near Bastogne.
Three more jamming missions were flown 2 - 7 Jan 1945 supporting Patton. 19/
The biggest reason the EW history of the German Ardennes Offensive is unknown has less to do with the esoteric nature of EW than the light it places on the Allied command decisions before the attack.
The surprise of the attack wasn't intel failure. It was command failure.

The snail like pace of Western military procurement versus the Ukrainian fielding of an all-aspect stealth shaped OWA drone in less than a couple of years is very noticeable.
On the morning of 20 July 2025, a AFGSC airman at Minot AFB took his M18, still inside it's issued holster; and placed it on a desk.
It then went off, struck him in chest, and killed him
AFGSC issued a halt order on 21 July 2025 for use of M17/18 Modular Handgun System.

As an ex-DoD procurement official, that letter is a procurement killing hammer.
This is going to hit SIG Sauer like a moderate sized asteroid in terms of DCMA corrective actions requests or "CAR."
2/
This AFGSC halt use order letter will be grounds for a level three corrective action request (CAR).
A DCMA level III CAR is defined as follows:
"A Level III Corrective Action Request (CAR) issued by the Defense Contract Management Agency (DCMA) is a serious action taken when there are significant contractual nonconformities.
It is directed to the supplier's top management and is just one step below the possibility of contract suspension or termination.
This type of CAR serves as a management tool to address critical issues that need immediate attention."
During WW2's combined bomber offensive, unitary incendiary bombs were found to be five times as effective as high explosive, mass for mass, at destroying buildings & structures.
But the bomber barons were hung up on the tonnage delivered, not their effects.
A single 100lb M47 bomb (left) was as effective as a M65 500lb general purpose HE bomb.
The Bomber Mafia in ETO fought incendiaries, as their bombers lacked the bomb station multiple release modifications for most of WW2, as the mass of bombs dropped was a 'success metric.'

After the bomber barons -finally- surrendered to the realty of incendiaries operational effectiveness.
Avoiding any USAAF responsibility for the horror that was Dresden cemented the burying of the effectiveness of USAAF firebombs used in the ETO.
"Russian aircraft manufacturers have failed to create analogues of foreign bearings and electronic components for aircraft, said Anatoly Gaydansky, CEO of Aerocomposite."

Low friction roller bearings are a major technological strength of the West.
They are the difference between Rolls Royce jet engines lasting thousands of hours and Russian or Chinese jet engines lasting half as long.
Rail roller bearings are different in their application

The following is a serialized post from Strategypage -dot- com on the disastrously bad US Navy leadership decisions on fleet maintenance & where they have left US National Security.
"Surface Forces: USN Maintenance Mess
1/
July 11, 2025: The U.S. Navy is no longer able to maintain or repair its ships. In an earlier economy move, all the navy ship repair and maintenance facilities were sold off. The worst aspect of this was the loss of skilled shipyard workers. ...
2/
... The older ones were retiring and the navy did little to recruit and train replacements. Now, as the United States strives to expand its navy and repair and upgrade current ships, it finds that the resources are lacking. There are no easy solutions.
