@danieljleahy & @ww2tv had a crackerjack stream on Australian Stuart tanks at Sanananda New Guinea this morning. Someone in the chat asked how they go there.

This thread will address that question.
1/
So, lets talk about the Australian Operation Lilliput that ran freighter convoys from Milne Bay to Oro bay in 1942.

The route that was used in Dec 1942 was pioneered by the US Army Small Ship Service (USASS).
en.wikipedia.org/wiki/Operation…
John Sheridan Fahnestock and Adam Bruce Fahnestock, friends with Pres. Roosevelt, originated the idea of a unit of small sailing ships to deliver supplies to Bataan, called “Mission X.”

It was a measure of the desperation of the time that MacArthur bit

These small boats were the key distribution mode for the SWPA. They moved supplies at night from advanced bases outside the bombing range of the Japanese Army and Naval Air Forces. Like the PT-Boat, their biggest enemy in 1942-43 was the small Japanese float planes...
3/
...that flew day & night plus were both low and slow enough to spot them. Then either these sea planes attacked, or worse, orbited and reported by radio to awaiting Japanese fighter patrols.
4/
The RAAN vessel HMAS Paluma (a 45 ton former examination vessel, see photo) did the actual surveys with the USASS luggers & fishing smacks the to find a reliable approach for larger vessels from Milne Bay to supply troops landed by air near Cape Nelson.

The 1st Lilliput convoy "Operation Karsi" was in Dec 1941, it took "...the former train ferry Karsik was pressed into service as an emergency tank landing ship, carrying four M-3 Stuart tanks of the Australian 2/6th Armoured Regiment to Oro Bay."

The Japanese took great exception to these convoys.

And given the geography of the Owen Stanley mountain range. The IJN had air superiority a few hours every day.

Photo left is of survivors of the s’Jacob, sunk on 8 March 1943, await rescue by HMAS Bendigo near Oro Bay
7/
The Allies in their turn took greater exception to these IJN attacks and deployed airfields radar & fighter control sensor network to gain air superiority & shield these sealanes.

This effort began before the Stuarts were delivered & went on after Sanananda was won.

The one thing I have not seen discussed with the impending major Russian invasion of Ukraine is the affects on world food security.

This USDA prediction of Oct 2021 will not come true.
1/
 fas.usda.gov/data/ukraine-g…
Specifically the USDA predicted this:

"Ukraine is estimated to increase production and, subsequently, exports of all major grains (barley, wheat and corn) for MY2021/22."
2/
A mid-February 2022 invasion of Ukraine will result in the April 2022 grain planting just not happening.

What happens to Europe's, heck the World's, food security if there is no Ukrainian grain in 2022 at all and millions of refugees?

The RAF airlift of AT-weapons to Ukraine is now 5 x C-17 sorties.

Rough order, you can fit around 400 FGM-148 or NLAW on 463L pallets on a single C-17.
1/
NLAW's inertial guidance is accurate versus moving targets to 400 meters and stationary at twice that. It uses a 15 cm Bill style slant down tandem HEAT warhead and will beat the front slope of any Russian tank.

You can't jam it.
2/
Only active defenses can stop and NLAW. And a tank hunter team can simultaneously fire several at the same tank to saturate an active defense.

Plus NLAW can be fired indoors.

Given the enormous interest in the "Electronic Warfare during the Battle of the Bulge" thread.

I'm posting a new thread whose subject is the historiography of EW in WW2 with foundational books, a road map of available primary sources, & recent research

1/
The late Alfred Price's "Instruments of Darkness: The History of Electronic Warfare, 1939–1945' is the foundational WW2 electronic warfare history.

It has been in continual print since 1969 with the last edition in 2020.

amazon.com/Instruments-Da…
2/
"Instruments of Darkness..." provides the some of the history of the "Battle of the Beams" but focuses on RAF Bomber Command's war with German integrated air defense system (IADS)

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.

@ArmouredCarrier @smooreBofB1940 @AC_NavalHistory @Drachinifel @MilAvHistory @MilHiVisualized @CBI_PTO_History @DrydockDreams @TheBaseLeg IJNAS single engine planes in service in 1941 were equipped with the Type 1 Ku 3 RDF system. This included the Mitsubishi F1M Type Zero Observation Seaplane, Allied reporting name Pete.

So IJN cruiser spotters could & did use the Yamamoto C3I System within range of the beacons.
@ArmouredCarrier @smooreBofB1940 @AC_NavalHistory @Drachinifel @MilAvHistory @MilHiVisualized @CBI_PTO_History @DrydockDreams @TheBaseLeg MacArthur's Central Bureau tracked single engine IJN float planes as a operational pattern warning of a major troop convoy before enciphered message traffic arrived.

I hadn't figured out how they were doing that until the role of M/F radio beacons came along.
@ArmouredCarrier @smooreBofB1940 @AC_NavalHistory @Drachinifel @MilAvHistory @MilHiVisualized @CBI_PTO_History @DrydockDreams @TheBaseLeg Those IJN float planes worked at night hunting for PT-boats as well as submarines by day.

They needed the beacons up to accomplish their missions.

When Central Bureau hear the beacons. They knew a troop convoy was in-bound.

The subject of this thread is the IJNAS C3I system behind the destruction of Force Z.

(I'll be using clips from Angus Konstam's book to illustrate this thread)
ospreypublishing.com/store/military…
1/
The anniversary of the sinking of Force Z is on the minds of many #twitterhistorians

For example, @ArmouredCarrier has three really nice videos on YouTube about the sinking of HMS Repulse
2/

Konstam's book is wonderful for most of the journalistic "Who, What, Where, When, How, & Why" on Dec 10, 1941, but it leaves out how the command control, communications & intelligence worked for the IJNAS Rikko Kokutai and why it came into existence in time to destroy Force Z.
