Re: Anatomy of the Ship Scharnhorst - Stefan Draminski

I received mine today. It is very well done, to say otherwise is untrue. Incredible heavy for an AOTS, 400 pages, the closest one (that I have) is Dreadnought with 256 pages. The plans are accompanied by 3D renderings, which are excellent to understand the superstructure. No, it has not the detailed...

Re: trawler damaged by explosion in North sea

Yes, any kind of detonator that needs no contact with the ship, mostly magnetic in WW2, I am not sure if there were acoustic detonators then, will go to Campbell´s book to confirm. They have interesting (and deadly) capabilities. For example they would go live after a preset time, not only for the l...

Re: trawler damaged by explosion in North sea

The mine proper has positive buoyancy, so it will always float near the surface, unless the mechanism in the sinker has failed and taken it to the bottom. If it exploded in the bottom it was most probably an influence mine, remember that they can seriously damage a ship in depths of more than 20 fat...

PARTE II​ Como se ha dicho anteriormente respondiendo al concepto de Operaciones del Comandante FT 79 en cuanto a intentar inducir al enemigo a dividir sus fuerzas, lo que en caso de concretarse daría lugar a una de las pocas situaciones en que se les podría infligir daño si estaban además aferradas...

Re: the main armament of the General Belgrano

Hi Francis. I think your info is pretty accurate, I only will add that may be the destroyers were equipped with depth charges of the old style too. I have a long text in Spanish, part of an official doc about the sinking, For lack of time I can not translate it, do you want it posted anyway so you c...

Re: the main armament of the General Belgrano

With the sub 100%, unless her CO made some mistake. The destroyers were in poor condition too, max speed about 20 kt, they were in close contact with the cruiser but sailing on her disengaged side, what assured that their sonars would not get the sub. I do not remember exactly her ASW weapons outfit...

Re: Loading big guns

Sorry, all the described tasks were done electrically or hydraulically. The levers just opened a valve for the hydraulics to actuate or closed a circuit for the electricity to power the motors. There were mechanical backups, but they are not what is shown in the movie.

Re: the main armament of the General Belgrano

I have in pdf the Report of Proceedings HMS Conqueror Operation Corporate, went thru the relevant parts many times. The weapon mentioned is the Mk VIII. The firing distance was 1400 yards, the three were launched with a spread set in their gyros, all this is compatible with an attack done with strai...

Re: the main armament of the General Belgrano

The hit forward...would not be different that the many suffered by USN cruisers that lost their bows courtesy of the Japanese Long Lance torpedo. These severed bows occurred at a structural discontinuity both internally an externally, externally because of the end of the armoured belt forward of A t...

Re: the main armament of the General Belgrano

I am not sure she would have survived with a better trained crew. AFAIK the aft impact killed most of the victims of the sinking, because the torpedo exploded just below the crew quarters when most of the crew was at rest. The other impact sectioned the bow just forward of A turret. May be in the Pa...

Re: the main armament of the General Belgrano

Paul, let me tell you some background. The Argentine armed forces were then composed of: -officers and NCO who assisted for 3/4 years to the corresponding military college/school -troop, which were composed from drafted civilians 18 years old. The drafted troops received about 2 months training, ser...
