Operations MO MI AL

Hi guys. I am curious about these names given by the Japanese to the operations of Port Moresby, Midway and Aleutians. They are found in every book. Question is, what were the originals names in Japanese language? Would they be so dumb as naming the ops with the first letters of the target...? Regards

Re: Anatomy of the Ship Iowa/Stefan Draminski

What about Draminski´s Bismarck AOTS? It is the only ship that received two books from the series.

Re: USN cruisers fire control top

Yes, I found the answer in Friedman´s US Naval Weapons. The director in Chester is Mk24, it had no range finder. The first US director that incorporated a range finder (in the way the DCT of the RN did) was the later Mk34.

USN cruisers fire control top

Hi guys. In the early days of centralized fire control, the director and the range finder were different pieces of equipment. The director was mounted on the top of the masts, and the range finders (there were more than one) in lower positions, on top of the conning tower for example. Between wars t...

Re: Fuze delay in aerial antiship bombs

Thanks guys, That times make sense. I can no longer find the 8-15 sec delay info, I remember it being used in bombs involved in the skip bombing technique used in the Pacific.

Fuze delay in aerial antiship bombs

Hi guys. I am looking for delay times. Contrary to artillery shells, which activated on impact and had a delay of about 10 milliseconds to the explosion, aerial bombs seemed to have a very long 8-15 seconds delay, don´t even know if the delay is post impact or post launching. Does anyone have info o...

Re: German machine guns

A little late for answering! The mechanisms are different. The MG-34 has a turning bolt, that locks to the barrel extension with a quarter turn, D4 is the rotating part. http://cdn.shopify.com/s/files/1/1524/1342/products/MG34GDF1_12_grande.jpg The MG-42 has a lug locking system, the two cylindrical...

Re: boys anti tank rifle

Hi Paul, it was created in WWI, when the tanks had far less armour than in WWII, would be useless against a WWII tank.

Re: Bismarck´s paravanes

So, a floating line could be introduced from deck, exiting at the base of the stem, floating to the surface and retrieved over the side with a hook? And then this leader used to pass a heavy wire to attach the paravanes?

Re: Bismarck´s paravanes

Thanks guys, now I am getting a clearer picture. What about Bismarck´s and her extending boom? What is the pointed line going from boom to deck in the diagram?

Re: Bismarck´s paravanes

Thanks Byron, I gave it a look.

Anyway, for me the question remains, I do not remember seeing a ship with the chains loops rigged near the bow, may be that´s how it was used in the monitors but don´t think it was the same for others (Bismarck for instance).
