@ArmouredCarrier @NaomiClareNL @AC_NavalHistory @Drachinifel @CIMSEC @CIMSEC_UK Electronic warfare is an attritional form of warfare.

The firestorming of Hamburg due to RAF Bomber command use of an early form of chaff, code named 'Window', did not end WW2.

The Luftwaffe adapted & a few months later "defeated" them over Berlin.

@ArmouredCarrier @NaomiClareNL @AC_NavalHistory @Drachinifel @CIMSEC @CIMSEC_UK A few months after that , RAF 100 Group developed a suite of EW tactics and suppressed Luftwaffe C3I for night fighters & flak. Image

This thread is another visit into the pyrrhic victory known as Operation Iceberg, the Apr 1945 invasion of Okinawa.

This thread is based on my Aug 2013 Chicagoboyz column "Technological Surprise & the Defeat of the 193rd Tank Battalion at Kakuzu Ridge"

This is a short thread on Japanese bulldozers in WW2.

There weren't many & they were small

My copy of Rikugun. Volume 2: Weapons of the Imperial Japanese Army & Navy Ground Forces 1937 - 1945 does not show a single Japanese bulldozer design.
1/ Image
There are a few hints about them on the internet.

In December 1942, the Imperial Japanese Navy commissioned Komatsu to produce heavy earthmovers for the purpose of building air bases.

See this link -- kenkenkikki.jp/museum/bulldoz…
2/ Image
Only 148 of the 5,000 kg Komatsu bulldozers were produced by the end of the war. Some were sent to the Philippines to build air bases

And note "Heavy" by Japanese standards compares to the 23 tons of a US D-8 bulldozer of 1943 vintage.

@adam_tooze @gideonrachman A UH-60 Blackhawk has a radius of action of 368 miles with external stores system fuel tanks.

The Chinese have copied & improved on this helicopter as the Z-20.

It is 130-ish kilometers in the closest Chinese coast to the closest Taiwan coast.

thedrive.com/the-war-zone/5…
@adam_tooze @gideonrachman The Z-20 has a 5-blade rotor system and more powerful engines as well as auxiliary wing-like hardpoints attached to it, similar to the Lightweight Armament Support Structure (LASS) and External Stores Support System (ESSS) wings on the US Blackhawks.

thedrive.com/the-war-zone/3…
@adam_tooze @gideonrachman Essentially, a fleet of Z-20's with external stores can do 2 round trips from Mainland China to Taipei loaded with 11 troops per lift.

Or they can trade fuel for weapons and play assault gunship to support infantry air-landings.

A Chinese coup de main vs. Taiwan is now possible

Alright, since the Bilge Pumps episode 52 is up, and I really didn't get a chance to go deep with US military 3D printing as is, versus what I see coming.

I'm going to drop a background thread here to do just that.

Note: long thread warning

 the-bilgepumps.simplecast.com/episodes/bilge…
3D Printing/Additive Mfg has been around for a while.

The four “foundational” patents for 3D/AM processes were issued one each in 1984 and 1986 with the remaining two in 1989.

Two National Science Foundation impacted 3D/AM patents were issued in 1987 and 1995. (See photo)

RAND in 2017 identified seven different 3D/AM Processes for seven material classes.

This is a thread on Normandy/Overlord airpower, signals & invasion stripes.

There was a neat post by @militaryhistori about D-Day to D+1 airpower talking about how many aircraft sorties the Allies racked & stacked over Normandy 6-7 June 1945.


1/
I replied to it with four photo captures of how the airpower flew during the daylight hours of June 6, 1944.

It was a whole lotta planes!


2/
I wrote a thread dealing with all of the above over on the Chicagoboyz blog on 2019's 75th Anniversary of D-Day here:

How Allied Planes Got Their D-Day Invasion Stripes and other "Retro-High Tech" Secrets of the Normandy Invasion

Paul Woodage's [@WW2TV] had a very nice video stream today with Kevin Hymel using information from his forthcoming book on Gen Patton.

This thread will expand on a piece of it regards Operation Huskey's friendly fire incident that killed 400 troops
1/
Operation Huskey's 2nd set of air drops resulted in 23 C-47 & C-53 troop carriers, & some gliders, being shot down with 400 US & UK paratroopers plus air crew aboard them. 
2/
 amcmuseum.org/history/a-very… Image
The friendly fire incident was due to the lack of a plan for centralized control of fleet and the just landed shore based anti-aircraft weapons.

The Report of Allied Force Airborne Board on Operation “HUSKY” is online (link)
