The Bilgepumps podcast crew's Episode 48 spent a lot of time discussing how USS Mustin (DDG-89) was dogging the new Chinese CVBG in the SCS.

This thread connects USS Mustin to some decades old open source intelligence on the USN.

the-bilgepumps.simplecast.com/episodes/bilge…
The OSINT story of the USS Mustin monitoring the PLAN CVBG in the SCS recently reaches back to the 1969 seizure of the USS Pueblo (AGER-2) by the DPRK

2/
en.wikipedia.org/wiki/USS_Puebl…
In the aftermath of both the 1967 USS Liberty incident and the "Pueblo incident," the USN decided to move the intelligence gathering role from auxiliaries to real warships.

One of the first warships so fitted after that decision was the Spruance class USS Caron (DD-970).
3/ Image
USS Caron's cover as an intelligence ship was blown by William Arkin in the Washington Post plus the Bulletin of the Atomic Scientists May 1988 edition.
4/
books.google.com/books?id=7wUAA… Image
The USS Caron and Aegis cruiser USS Yorktown were both rammed by Soviet warships in Feb 1988.

They were doing a freedom of the seas exercise passage between the US recognized 3-mile limit and the Soviet's claimed 12 mile territorial limit.

5/

Arkin's Washington Post story emphasized the fact both Yorktown and Caron carried nukes and their exercise "endangered the world with a possible nuclear accident."

AKA the usual left of center anti-nuclear cant of the Late Cold War era.

6/
What was really interesting in Arkin's Bulletin of the Atomic Scientists piece was the extensive detail on the USS Caron's operational patterns, as well as it's possession of Tomahawk targeting gear, that was clearly planted via Soviet intelligence.

7/
navyhistory.org/2012/04/outlaw…
The USS Caron's danfs history entry shows that she had both OUTLAW SHARK and CLASSIC OUTBOARD systems.

8/
history.navy.mil/content/histor…
The danfs USS Caron entry states:

"The destroyer’s 1979 cruise book proudly noted that Caron became the only Atlantic Fleet destroyer with both Classic Outboard and Outlaw Shark installed and was the first ship to operate the two systems simultaneously."
9/ Image
As mentioned previously, Outlaw Shark was an ELINT targeting system for antiship missiles. For context, see:

Christopher Ford and David Rosenberg's "The Admirals' Advantage: U.S. Navy Operational Intelligence in World War II and the Cold War"

amazon.com/Admirals-Advan…

10/
USS Caron's other intelligence system, CLASSIC OUTBOARD (Organizational Unit Tactical Baseline Operational Area Radio Detection Countermeasures Exploitation System) AN/SSQ-108(V) was a US Navy shipboard direction finding system.
globalsecurity.org/intell/systems…
11/
William Arkin's two 1988 pieces gave away the operational pattern for all USN intelligence tasked warships.

Black Sea visits, loitering off hot spots, presence during major nav-ex, freedom of the seas passages in contested areas are all the meat & potatoes of intel-DD's.
12/ Image
While USS Caron was given 64 VLS tubes in one of her refits. She was to be decommissioned in 2000.

This is where Arleigh Burke-class guided missile destroyer USS Mustin (DDG-89), launched in 1998, enters the story.
13/ Image
The USN had to replace the USS Caron with a new intelligence DD and replacement intelligence platforms need a working up so there is no gap in coverage.

The timing of the USS Mustin's launch and her recent PLAN CVBG trailing mark her as Caron's replacement as intel-DD.

14/ Image
While USS Mustin is obviously an intel-DD, she is far from the only one.

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

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

@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.

en.wikipedia.org/wiki/Bombing_o…
@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

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:
