Re: British Cruisers: Two World Wars and After

There is a good description of the Mk-37 system in "Sumner-Gearing Class Destroyers" (Sumrall). The Mk-37 sent the range (obtained by radar) and target´s bearing to the Computer Mk-1, so it could calculate the speed and course of the target and predict its future position. As the computer used a sta...

Re: Admiral Graf Spee

Hi guys. I have sailed close to the wreck, is near Montevideo port. The water is not very deep there, may be around 8 m. The superestructure has been cut, so there only remains the hull and the main turrets, some of the secondary has been removed.

Re: Bunker fuel versus Diesel oil for Marine Diesels

There was a boiler, used among other things to warm the diesel oil. I think this was done to give it the proper viscosity.

Re: Nicaraguan military invasion to Costa Rica

Hi Karl. Costa Rica has no armed forces of any kind? I know that you have no army, but don´t you have a heavily armed border patrol force? Isn´t your security guaranteed by the US?

Re: Mission and propulsion for H-class battleships

I looked in Garzke´s. He says that the propulsion was chosen because it was asumed that the ships would have to travel many miles (from North Sea to the Altantic via north of England) before reaching operational ground, be it for commerce raiding or other missions.

Re: Mission and propulsion for H-class battleships

For one thing the H class battleships look like a fair amount of over kill for commerce raiding.
Was not that true even for Bismarck?

Re: Firing Key Mark XIV Mod 1 info?

As I said, and by your description, I presume that it is the mechanism used to fire a bagged charge. Surely it is inserted into the back of the breech block, and a cord bound to some form of trigger, so you pull the cord that pulls the trigger, and it detonates the explosive tube that goes in to the...

Re: Firing Key Mark XIV Mod 1 info?

May be it refers to a tube that is inserted in the breech block in order to fire a bagged charge. Or the mechanism that detonates the mentioned tube. Can you provide any photo?

Re: German Destroyer - Bernd von Arnim

I didn´t see it Dave. Can it be downloaded? Anyway, the case of Narvik is a bit different, it was at the beginning of the war.
