@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.
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.”
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. 5/ ozatwar.com/sigint/paluma.…
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." 6/ awm.gov.au/visit/exhibiti…
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.

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.
400 Houthi aerial drones, cruise missiles and ballistic missiles were fired at/near USN ships since Oct 2023
120 SM-2 & 80 SM-6 missiles, 160 five-inch main guns rounds, plus a combined 20 Evolved Sea Sparrow and SM-3 missiles engaged them.
Drone War Cost Trades 🧵 1/
Tyler Rogoway has reported the following missile costs:
SM-2 Block IIIC - $2,530,000 per missile.
SM-6 - $4,270,000 per missile.
Evolved Sea Sparrow Missile (ESSM) RIM-162 Block II - $1,490,000 per missile.
SM-3 -$12,510,000 for the Block IB, and $28,700,000 for the Block IIA 2/
So:
120 SM-2 * $2.53 million = $303.6 million
80 SM-6 * $4.27 million = $341.6 million
12 ESSM (guess) = $17.88 million
6 SM-3 IB (guess) * $12.51 million = $75 million
2 SM-3 IIA (guess) * $28.7 million = $57.4 million
The fire and forget millimeter wave (MMW) radar guidance AGM-114L "Hellfire Longbow" being referred in the War Zone post as "a new anti-drone armament" for the LCS actually ceased production in 2005 and reaches end of life in 2025.
One of the reasons the AGM-114L was dropped from the US Army M-Shorad is the US Army didn't want to pay money to recertify the AGM-114L inventory...

...with the AGM-179 Joint Air-to-Ground Missile (JAGM) equipped with dual-mode Semi-Active Laser (SAL) and millimeter wave (MMW) radar seeker just entering production.

The process was invented by a Russian, Via wikipedia:
"The Russian chemist Sergei Vasilyevich Lebedev was the first to polymerize butadiene in 1910....

...In 1926 he invented a process for manufacturing butadiene from ethanol, and in 1928, developed a method for producing polybutadiene using sodium as a catalyst.
The government of the Soviet Union strove to use polybutadiene as an alternative to natural rubber ...
