Destroyer acceleration

Hi Guys

Trying to work this one out, hope someone can help

A British A class Destroyer is sailing at 16 knots, she spots a U-boat and goes into action, how long would it take her to work up to a speed of 25 knots?

Regards

 

They said there would be no math on this forum!

 

oops Sorry.

Ok I will rephrase, what is the average acceleration speed of a WW2 British Destroyer Hope this is ok

Regards

 

Don't worry somebody here is likely to be able to answer this one, give it a little time.

 

I'd give it a lot of time...my brain hurts...Won't it depend also on local weather conditions....?

 

Average acceleration is not likely to help much. Ship acceleration is very nonlinear.
There's a power setting curve for Yamato at

along with some discussion of Japanese destroyer fuel consumption that represents some clues. However DDs of different nationalities showed a huge variation in such things.

One of these books might have an answer:

If you could get access to the ship logs for thier acceptance trials that might also be a good source. The USN has some on line I'm not sure about the RN.

 

African or European destroyer???

 

Thanks for the input, and The Charge of the Light Brigade!

The website U-Boat Archive has reports on the sinkings of many U-boats, there are likely to be a few that are useful to you. The various reports can be found here: http://www.uboatarchive.net/Uboatlist.htm

But is that as sad as when passing ruffians can say "Ni" at will to old ladies?
