@IntelCrab @IntelCrab, you may have just made the single most important observation of the 2021 Gaza War.

Underground fiber optic cables are extremely & uniquely vulnerable to the seismic shock from high order detonations. They stop transmitting light when subjected to them.
1/
@IntelCrab This fact was used in the 1991 Gulf War Scud Hunt. Saddam used fiber optic cables to communicate to Scud hide sites.

Many air strikes US SF teams called down in the western Iraqi desert were to "sanitize" an area of fiber optic cables after flushing a Scud launcher.
2/
@IntelCrab The collapsing Hamas commercial internet bandwidth, decreasing Hamas ability to coordinate large rocket launches, and the IDF's sustained bombardment of North Gaza combined with that GW1 fact tells me the IDF is destroying underground fiber optic cables.
3/
@IntelCrab To paraphrase the Roman original:

The IDF are making a (bandwidth) desert in Gaza and calling it peace.

@boys_ian @Steveho25139795 @clark_aviation Radar proximity fuzes were a UK concept & engineering development that it took American industrial capacity to make real. (photo)

Time fuzes came in 2 flavors.

Flavor 1 was mechanical like an old Swiss watch. Flavor 2 was a burning pyrotechnic fuze.

Flavor 1 kept better time
@boys_ian @Steveho25139795 @clark_aviation Flavor 2 was far lighter and MUCH cheaper.

This meant barrages and director controlled pointer fire using mechanical fuzes were much more consistent in altitude.

But the pyrotechnic fuzes could reach higher flying USAAF bombers in 1944 that mechanical could not.
@boys_ian @Steveho25139795 @clark_aviation This article (link) is a good one for explaining German AA gun defenses as a system.

The key pacing item for German flak defenses were the directors, mechanical-analog fire control computers. (photos)

This James Dunnigan strategypage.com article lists the export customers for the Israeli Iron Dome system. The listed nations are as follows:

India
Romania
USA

Text from the posted article:

"Using Iron Dome effectively has always been a matter of numbers. In the 2014 50-day war with Hamas, Iron Dome intercepted 735 Hamas rockets, which were 90 percent of those headed for populated or military base areas...
...That was up from the eight-day 2012 war where there were 421 intercepts and of those 84 percent were headed for populated or military base areas.

One of the crying shames of academic WW2 history is it's unwillingness to address what we now call electronic warfare.

The Ham radio community is both different & far more useful.

See:

Now to explain why Ham radio guys can be a whole lot more useful that academic & archival historians** for EW -- the 2 August 1939, LZ130 Graf Zeppelin flight.

**Note: Every field has it's weak points. Extremely few academic tract historians are radio geeks...
2/
...and being a radio geek is a better skill set for the subject matter than most PhD's not awarded to Dr Alfred Price.

LZ130 flew one of the first ELINT missions ever, against the UK Chain Home system with 25 RF engineers aboard.

@DrydockDreams has put up another Coral Sea post modeling ships & US Navy CAG William Ault plus his disappearance returning from the strike against IJN CarDiv 5.

This thread goes into what the role of preventable HF communications failure played in that

...disappearance.

To do so I will be using screen captures from Squadron Leader A. L. Hall, RAAF, presentation "farewell to communication failures" reprinted in the Aug 1944 CIC magazine

This is a clip showing the beginning of S/F Hall's manuscript.

WW2 wartime military periodicals often have 'retro' or 'era specific' high tech buried in the articles that modern eyes will not understand.

@DrydockDreams has a great post up on the Battle of Coral Sea with models of the ships sunk there.

This thread is going to take a lessor known road in exploring that battle.

Namely, why search plane radio communications sucked in the battle.
1/
When people remember the Battle of Coral Sea. These are the sort of strategic and tactical maps people use to understand the battle.
2/
This map is not one normally used for the Coral Sea, but is absolutely necessary backdrop to it.

These are the active Japanese seaplane search sectors in May 1942.

So...why didn't they both spot USN CV's & pass on data to the Japanese CV's?

This thread is the fourth visit to the logistical disaster known as Operation Iceberg.

1/
The three previous threads have dealt with the hidden friendly fire, USN doctrine & a horrid staff planning error that left far too few staffers to plan because of a grand standing USMC general/Deputy Chief of Staff in 10th Army .

"Failing to plan is planning to fail."

2/
This thread focuses on how unexamined CentPac & 10th Army staff assumptions in changed combat conditions turned around and bite them all in the assets.
