Coal burning merchants and escorts for the Japanese?

Just had a thought regarding the Japanese Oil shortages and their navy/merchant fleets. Would it have made more sense to use coal burning vessels for merchants and destroyer escorts? It seems on the surface that this would have somewhat alleviated the need for oil which hamstrung their navy. I know ...

Re: Japanese CA's and the Long Lance

Just one more point on the S Dakota's and New Jersey's decision for an internal belt - In addition to not working as a de-capping layer, the internal main belt posed a few problems. One was that piercing of the outer armor (which was comparatively easy to penetrating the main armored belt) could res...

Re: Japanese CA's and the Long Lance

Well, your comments about de-capping makes me feel better about the issue :D It just seems that de-capping is used so much by American BB fanboys to say why the South Dakota and New Jersey were so incredible of ships. Granted they were nice state of the art battleships, newer than most almost any ot...

Re: Japanese CA's and the Long Lance

Interesting theories on deck armor. Seems to me at short to medium range it's likely to work to decap as you might be looking at 80-85 or so degree angles. As you get further out, it's less likely to decap as the plunging fire angle angles become close to a 45 degree or so. Against bombs though it d...

Re: Japanese CA's and the Long Lance

A question just came to mind that I do not see an answer for. Is it the angle of obliquity of the decapping layer that is calculated? Or the angle of obliquity of the underlying belt? I know the South Dakota's main belt was inclined at 19 degrees. Was the outer layer inclined as well? And if not, I ...

Re: Japanese CA's and the Long Lance

De-capping has been studied ten ways to Sunday for decades. It is not all that inexact. My point as that if one of the current "authorities" on the subject has had to change his "rules" if you would or laws as to how a de-capping layer performs, then it is still somewhat inexact. I guess my biggest...

Re: Japanese CA's and the Long Lance

This is in keeping with un-capped shells striking face hardened armour at velocities above what is called the critical velocity. The de-capped shell will shatter when striking the face hardened armour in such conditions even if the thickness of the armour is not thick enough to defeat the same shel...

Re: Japanese CA's and the Long Lance

These torpedoes were not shot from 3 point range (see Frank). They were from inside the paint. They were shot at 7,000 meters or less, at good angles with good solutions. You missed the analogy I was making. I meant that surface to surface torpedo fire is by it's own nature less predictable than gu...

Re: Japanese CA's and the Long Lance

What about the failures of IJN torpedoes during Second Guadalcanal? It cost the Japanese that decisive battle. I would not say the torpedoes "failed" in a mechanical sense, they just were inaccurate. Kind of reminds of a team that shoots a lot of 3's in basketball - when they hit, great, when they ...

Re: Japanese CA's and the Long Lance

IJN design philosophy, in consequence of the nation's certain position of numerical/productive inferiority in a war against the USA, was to seek a technical edge wherever possible. Yes indeed. Though I think that merely having 12-16 fully functional non O2 based torpedoes gives one a tactical super...

Re: Japanese CA's and the Long Lance

Spoken like a true American CA skipper, Steve :D , or at least a proponent of the Baltimore class. But I think Torpedoes were indeed a viable option for CA's who's primary job was to engage other warships. The Japanese hi at about 7% with their surface to surface torpedo fire, but looking at later w...

Japanese CA's and the Long Lance

Any thoughts on if the Japanese CA's should have carried the Long Lance? I'm not suggesting they go without torpedoes. The Japanese did have some pretty effective non oxygen based torpedoes, and Japan did not seem to have the problem the US did with fuses/detonation. Put a little R&D into coming up ...

Re: 1939 Battleship Forces: US Navy vs Royal Navy

I was thinking of the some of the British R-class and some QE class, limited to 20* and 23km max range, IIRC.
Good point

I guess I was in essence re-iterating your comment. :D

Re: 1939 Battleship Forces: US Navy vs Royal Navy

Most of the guns installed had maximum ballistic ranges of below 30km, and effective ranges below 27km due to elevation limitations While this is true for those having 15 degree max elevation, the ship with limited to 15 degrees where outnumbered by those with a 30 degree or better elevation, at le...
