@tac_air_power@ReassessHistory The IJA needed to protect its trains from 14th AF raiding. They blanketed China with both ground observers & radar. Then fed the information into filter centers that warned the trains.
Shades the 1999 Serb F-117 shootdown, the IJA had observers watching 14th AF air fields.
@tac_air_power@ReassessHistory To make it even more interesting, the IJA built revetments on railways, railway sidings & in switching yards for their locomotives to take cover in as protection from strafing & bombing!
The Germans were not that smart in 1944 versus Allied airpower!
@tac_air_power@ReassessHistory As for your "standing air patrols were the only alternative to radar" comment. Whether you are aware of it or not. You are conflating the Sept 1940 threat environment after Norway & France fell to the 1932 to Aug 1939 threat environment RAF Fighter Command was planning for.
The RAF anticipated having to defend Great Britain against massed formations of unescorted enemy bombers on one threat vector over the North Sea.
@tac_air_power@ReassessHistory You needed neither radar not standing fighter patrols to deal with such threats. Picket boats with radios could do the job in 1932 - 1940 just fine.
In fact, picket boat No. 23 Nittō Maru, a 70-ton patrol craft, did that on April 16, 1942.
The 1st the Doolittle raid task...
@tac_air_power@ReassessHistory ...force knew of the picket boat was when it started transmitting. (Typo note: 18 Apr, not 16 Apr 1942)
A screen of @AC_NavalHistory "Dog boats" in the North Sea and a RAF Wireless Observer Unit system deployed in Northern France would have been sufficient for the early warning
RAF Fighter Command did not think that way because wireless observers in RN Dog boats would have been a threat to Fighter Command's depression era budget.
Radar was an innovation that kept Fighter Command's budget intact.
@tac_air_power@ReassessHistory@AC_NavalHistory This brings up the point that military innovation happens for a lot of reasons. The German manpower bind was such pre-WW2 that Radar for them was a labor saving device.
The Luftwaffe innovated with radar was it reduced the manpower demands of visual air defense ground observers.
@tac_air_power@ReassessHistory@AC_NavalHistory The radar narratives of WW2 handed down in the institutional histories were 1st & foremost written to serve the Flag rank career & budget goals of the military services writing those histories at publication time hack.
All that was necessary was for ground observers and defending fighters to have radios that could talk to each other.
The attached map is from a 1933 exercise where then Captain Claire Chennault proved that.
@tac_air_power@ReassessHistory I've written a couple of Chicagoboyz columns addressing the institutional lying attached to "The bomber always gets through."
@tac_air_power@ReassessHistory Umm... the issue when the Baldwin made the comments was the use of bomber delivered mustard gas on civilian populations.
And for that to be militarily useful, you needed something a lot better than a 5-mile/8km CEP Bomber Command was getting before Gee was used.
@tac_air_power@ReassessHistory The USAAF 8th AF flying during the day with the aid of Bomber Command Gee, LORAN and H2X radar could not drop a bomb within 1,000 feet of a target 1/2 the time before March 1945.
This chart does not include "systemic error" that saw 8th AF bomber streams hitting Swiss cities.
@tac_air_power@ReassessHistory These are the average "instrument errors" from the various WW2 radars and radio navigation systems on heavy bombers versus the Norden bomb site on a sunny, 0/10ths cloud day.
Flak shooting at these planes with these instruments made the CEP increase to several miles.
This thread is on combat actions 76 years ago yesterday & #OnThisDay, 6-7 Apr 1945 at Okinawa. No, not on the sinking of the HIJMS Yamato which @JHistoryC covered very well here:
No, I'm talking about USN leadership failures on those dates at Okinawa. 1/
Failures that lead to this.
Six US Navy planes were blown out of the sky by US Navy anti-aircraft fire.
Four of those six planes were in the landing approach pattern for Yontan Air Field. 2/
Worse, one of the FM-2 Wildcats shot down exploded in mid air and it's wreckage landed on fuel barges off Hagushi Beach.
The wreckage was tracked by every ship AA gun into barges & strafed Kadena airfield downrange. The results were both horrific & operationally significant. 3/
Since COVID-19 has kept the major archives closed or so limited in access they might as well be. This thread is an examination of an on-line source of primary sources here:
The bulletpicker.com collection went public in late May, 2016 and has a huge number of ordnance, small arms, and defusing related items.
The library section is the heart of the site and it covers WW2 UK, US, Australian, and technical intelligence by those powers on German, Italian and Japanese ordnance, engineering and small arms.
This is another thread on Imperial Japanese radar countermeasures in WW2.
This thread will also include the US inter-service intelligence/classification/budget wars between the Joint Chiefs & MacArthur's Section 22 radar hunters. 1/
The information in this thread is coming from a 28 May 1945 training document from Boca Raton Army Air Field.
William Cahill of the Sec 22 Special Interest Group found it in Late Feb 2021. 2/
What Cahill found in RCM Digest 14 was yet another bit of Japanese radar countermeasures.
One utterly unique in the history of electronic warfare. 3/
