I have just recently noticed that on the Kriegsmarine grid square map there is no second letter I. There is AH then AJ. DH then DJ.

Any one know why? :hmmm:

many armies exclude the I when it can be confused with an 1.
same for O and 0...

The KM grid map has no 'I', not because it can be confused with '1', but because it can be confused with 'J'. Same with the US Air Force when giving sub-variant letters to aircraft.

Oddly, though the Royal Navy had both 'J' and 'I' class destroyers in WW2, in WW1 there was no 'J' class, for the same reason.

Weird...

There was an F-4J. There was no F-4I.

Likewise in WW2 there was a P-38J, but no P-38I.

Further to Sailor Steve's answer - might be due to the fact there are no number 1s on typewriters, you use lower case 'L's instead. So lower case 'L' is reserved for number 1, and all KTBs were typed up on typewriters on return to base.

Combine that with the fact that most military telegraph printers of the day printed in lower case (in order to differenciate between 'o' for Oscar and the number 0), so there's no way of differenciating between a '1' and an 'L'.

Don't know that for a fact, just those two seperate bits of trivia (I use a typewriter at work oddly enough) might also be contributing factors in this typographical conundrum.
