Re: A Force Z What If

Kondo will try to position his fleet to cut off Phillip's path to Singapore and beyond. Then he will send in his destroyers. He probably doesn't want a running fight from plus 20,000 yards going toward Singapore to the west of the Anamaba Islands. There was minefield there that both sides knew about...

Re: Operations MO MI AL

The third writing system in Japanese is the Kanji. Kanji is not phonetic, but uses symbols to convey a meaning. It can therefore convey a more complex meaning than just the sound of a word. The Kanji borrows its symbols from Chinese but they may or may not mean the same things in Japanese. A Kanji w...

Re: Operations MO MI AL

The use of Roman letters, or Romanji, within the Japanese language date back to 16th century AD when Christian missionaries needed a way to cross translate scriptures. Of course if morse code is used, Romanji must be used instead of Japanese script. There are three writing systems in Japanese over t...

Re: German Radar

During Operation Berlin S&G still operated FUMG39 sets. The MK2 sets were available and installed on new construction. However, S&G did not get the updated technology until after they arrived at Brest.

It wasn't until after noon that the Army advised Com14th of the radar track Lockard and Elliott developed at that radar installation on the north side of Oahu. (Now what was that name again?)

Re: Leyte gulf

The USN was much better at night fighting than they were earlier in the war. How could they not be? I know there was at least one case where USN DDs ambushed some IJN DDs with torpedoes at night, using radar as their primary sensor. I agree that USN was much better at night fighting as the war prog...

Re: Halsey on Leyte Gulf

The massive battle opportunity was the Battle of the Philippine Sea during June 1944. The reason a massive surface fleet engagement did not develop was because of the complete domination of USN air power, and Adm. Lee's refusal to fight at night. Actually, Philippine Sea had influence on Halsey's de...

Re: Leyte gulf

You seem to be saying that the Japanese radar was superior to the Mark 3 fire control radar which was mounted on many US battleships and which couldn't be used successfully against Yamashiro at Surigao Strait. Only the three BBs with Mark 8 could get radar ranges. So hypothetically the IJN had a te...

Re: Leyte gulf

I’m taking a more historical perspective rather than assuming that US carriers do not exist. Instead since the hypothetical assumes Musashi is still available, I am taking it as Musashi isn’t sunk or significantly damaged by the carrier strikes. I think looking at the various angles from this basis ...

Re: Damage to German warships in Brest

One book on the Atlantic Ports reports that Scharnhorst completed repairs by Nov, 1, 1941, by bringing in extra technicians from Germany and also the U-boat repair facilities at the Biscay ports. Another source specifically reads that the Gneisenau was declared fully operational in the OKM briefing ...

Re: Damage to German warships in Brest

Schmalenbach included a drawing detailing the damage to PG in his Under 3 Flags book (pg142). The bomb hit just inboard of the intersection of the oberdeck and the side plating. A few inches outboard and it would have missed. A few feet inboard and the damage probably would not have been as signific...
