Draft article on Mk 24 Mine/Torpedo aka FIDO completed

I have just completed and sent off a late draft of the FIDO article I have been preparing for what seems like forever to Battlefleet, the journal of the Naval Wargames Society. After this is published I will post a copy on my academia.edu site. There is a possibility that I might prepare a presentation based on this article for this years DSTL symposium on Historical Analysis, we will have to wait and see if this pans out.

As a taster though: One of the things discussed in the paper is the effectiveness of FIDO and to do that we need to be able to compare  its contribution to an attack compared to what an aircraft could have carried in its place. In order to make such a comparison I needed data on the kill probability of depth charges as a function of number in a stick. Fortunately this data is included in Waddington's: Operations Research in World War 2, some of which I have reproduced in the form of a table which is shown below:

# of DCs
Prob of Kill
Prob of Damage or Kill
2
18%
24%
4
31%
40%
6
45%
53%
8
57%
~70% (extrapolated)
