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: US Battleships

The main armored deck of the West Virginia class was only 1.5" of STS laid directly on 1.5" of mild steel.

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...

Re: The Swordfish's Torpedo misses Bismarck

It was not until September that attacks on the German warships were resumed with each quarter moon phase, obviously only at night. The attacks were much larger in scale with about 150 bombers per raid, and included more and more four engine heavy bombers carrying more and/or larger bombs. Moreover, ...

Re: The Swordfish's Torpedo misses Bismarck

July 23. The location of Scharnhorst had been confirmed by a recon flight on July 23 in La Pallice, 200 miles to the south. Scharnhorst was running machinery trials there. Some secondary sources claim that the scheduled night raid on Brest was moved to the next day to ensure hits in an attempt to si...

Re: The Swordfish's Torpedo misses Bismarck

The first raid against S&G occurred on the night of March 30/31. 109 bombers were sent. They scored no hits. Examination of the bomb fragments indicated the use of armor piercing bombs, leaving no question of the intentions. April raids on Brest: April 3/4 90 bombers. Target area not found. 3 lost. ...

Regarding the question of how Bismarck may have fared in French Atlantic ports, and the capabilities during 1941 of RAF Bomber Command: During the last few years I have been interested in researching Bomber Command’s operations during 1941. I was surprised by some of the findings. The arrival of S&G...
