I guess I should start an AGM-86 ALCM thread; since I dropped the ill-fated AGM-109 variants.

ALCM as we know it began with something completely different -- the SCAD (Subsonic Cruise Armed Decoy) program which began in 1969 or so to replace the earlier QUAIL decoy.

SCAD A would have been for the B-52, while SCAD-B would be for the B-1A.

Both would have had the option of a nuclear warhead.Image
Image
Image Somewhere along the way, SCAD became the AGM-86 SCAD, and then the ALCM. At this point (December 1974 and the ZAGM-86A) there was an option for a drop tank for extended range.

Once upon a time, @heatloss1986 there was a plan for the USAF to buy the Tomahawk. Image @heatloss1986 Naturally, the AGM-109 would have been launched from tons of platforms ranging from KC-10s... Image

I've had some time to think about the Chinese "filled with water" claims; and I think I know what happened.

Every modern ICBM has what's called the "Post-Boost Vehicle"; which aims and releases the warheads following ICBM burnout.

Picture is of an American PBV.

1/ Image Virtually all PBVs use some form of liquid hypergolic propellants -- there are only a few exceptions, such as the USN's Trident PBVs which use a series of solid propellant gas generators to avoid hypergolics on a submarine. (They also have much less delta V)

US Casualty Care in WW2, a thread.

"The Surgical Management of the Wounded in the Mediterranean Theater at the Time of the Fall of Rome"

ncbi.nlm.nih.gov/pmc/articles/P…

Has a nice diagram showing US casualty care circa the summer of 1944.

But how did all this work?

/1 Image books.google.nl/books?id=lFIEA…

LIFE Magazine in their 29 January 1945 issue followed one specific casualty from his wounding to arriving in the US.

I've seen the following casualty rates tossed out:

150K UA v. 220K RU = 1.46x (RU journos connected to RU .mil)
100K UA v. 180K RU = 1.8x
100K UA v. 200K RU = 2.0x (US/NATO estimates)

The spread between RU and NATO cas estimate ratios isn't that great; the avg is 1.77x

/1 Prior Ratios are:

1991 Gulf War: 100 to 114x (unclear)
2003 OIF: 20x (unclear)
1956 Suez : 10.34x
1967 Six Days: 3.7x
1993 Mogadishu: 3.42x
1945 Okinawa: 2.44x
1979 Soviet-Afghan War: 2.19x
1973 Yom Kippur War: 1.5x
1942/43 Stalingrad: 1.29x
1945 Iwo Jima: 1.25x

@TrentTelenko, Shoigou may have inadvertently revealed🇷🇺casualty ratios back in Sep '22 when commenting on🇺🇦casualties.

armenpress.am/eng/news/10930…

That comes out 55.4% KIA, 44.6% WIA - and that's for the first portion of the war when conditions were more favorable to Russia.

/1 @TrentTelenko Socialist scientificism (for lack of a better term) required incredibly precise figures when stating things in the USSR. So when it came to analyzing 🇺🇦 casualty estimates; Shoigou's speechwriters used 🇷🇺 ratios to get those numbers. Oops.

A while back I saw a comment by someone (can't remember who, sorry) that the most common 🇷🇺 tank AP round was 3BM42 'Mango' APFSDS -- which is a pretty "old" round that entered service in...1986.

/1 I just realized now that the use of MANGO may be due to the Frankensteined status of the 🇷🇺 tank fleet -- you have a lot of older tanks from the 1980s still in service; albeit lightly modernized.

@TrentTelenko, I am seeing some rumors that a boat was passing under the Kerch Strait bridge just before it exploded. 🤔If true, it means JAVAMAN rides again.

For those of you who don't know, JAVAMAN was part of the overall US effort to develop robot drones in WW2.

/1 @TrentTelenko The USN had it's own WW2 drone program, which was

PT Boats: 30 kts with 17 tons of TNT
Destroyer Escorts: 17 kts with 1,200 tons of TNT
Cargo Ship (AK): 13 kts with 8,000 tons of explosives

@TrentTelenko @azeem You know, on second thought...now that I've had time to think about this, @TrentTelenko is correct. I've been basing my assumptions on "classic" World War II studies for aerial spraying or artillery shell delivery (ref 1946 FM3-5 / FM3-6); which are wildly inefficient.

/1 @TrentTelenko @azeem During WW2, they did a lot of studies on how best to deliver CW; and found that aerial spraying from high altitude (12,000+ ft or so) didn't work as well as from low altitude (200~ ft or so).

This is an elaboration from an earlier tweet thread by me:

()

Now that I've had time to sit down and type things out on a real keyboard; I think the reasons for the Russian Collapse we're seeing go back several months.

/1 I think that since around May or so of this year, the majority of RU ground forces along the front have been skeletons -- i.e. only 50 or so men in a 700 man BTG; whether from pre-war corruption, or combat losses with no replacements.

In my previous thread; I talked about how "firepower oriented" RU design philosophies were, in relation to other priorities. After some thought, I feel that a little more information is necessary. We'll start off with this declassified CIA summary from 1980.

/1 Image In the post-WW2 era, well into the 70s; a lot of military thought centered around the classic "WW3" scenario -- where there would either be the outright use of tactical nukes from day one, or days of increasingly high intensity conventional war ending with strategic release.

Let's discuss this captured BMD-4 walkthru posted on Ukraine Weapons Tracker:



1/ As previously noted by UWT; it's previously unseen footage; the snow indicates it was videotaped perhaps in February or March.

A thread on Russian Navy firefighting capabilities.

A friend of mine pointed out an article (in Russian) from November 2018 that had been getting some attention recently.

/1 Apparently Soviet ships designed before 1980 did not have a fully centralized fire alarm system. The Project 1164 (Slava) Cruisers, of which Moskva was one, fell into this period; having been designed in the early 1970s.

A thread on corruption in the Russian Navy.

There's a strong possibility that the Moskva's Anti-aircraft systems may have been severely degraded before the war.

A nameless anon on 4chan posted the text of a news article that piqued my interest and prompted this thread.

1/ Back in 2012, Captain of the First Rank (equivalent to NATO OF-5 Captain) Igor Supranovich (Игорь Супранович) was the Deputy Head of the Department of the Ministry of Defense for ensuring State Defense Orders.

He had contract authority over the following systems:
