I've made a new topic in the technology forum regarding the use of type 273 and 284 radar, but it also shows an AFCT in use and target plotting:

This is a RN training film showing the use of Type 273 and 284 for WS and GS: https://www.iwm.org.uk/collections/item/object/1060020035 The 4 part video shows the sequence of events from initial detection to blind firing using Type 273 and/or 284. The 2nd part of the film is mislabeled and you have ...

Hello everybody, @ Wadinga, on December 2nd, 2018 I have posted : http://www.kbismarck.org/forum/viewtopic.php?f=1&t=8335&start=165#p81496 The bearing communicated at 05:44 from PoW was 335° T and not 325° T as you can read on the posted original messages.

Just an FYI for everyone, especially Bill Jurens, who may have missed it. This data is extracted from the Admiralty War Diary and the two files contain all the relevant RN radio transmissions from May 22/23 onward: http://www.sfu.ca/~dmunro/images/Bismarckops.pdf http://www.sfu.ca/~dmunro/images/Bi...

We know that Brooke had to be viewing Bismarck because his director never shifted targets, and apparently never did the forward DCT because both directors were slaved to the same bearing. The field of view in Brooke's optics was very small and he couldn't see Prinz Eugen during the action.

Hello everybody, do not even try to tell me that Suffolk did not have the 1 degree accuracy on the bearings. It is enough to read her reports : 0447 (B). Enemy bore 186°, 15 miles, course 220°, speed 27-28 knots and bore 196° at 0456 (B). 0520 (B). Enemy bore 203°, 15 miles, possibly increasing spe...

Hello everybody, since we will be mainly covering distances and mostly the relative bearings taken visually, ... below the 16 sea miles close to the horizon line, ... starting from the smoke and after looking at the enemy warships, ...

This would seem to be a good start. Does any other correspondent wish to either add a document or for whatever reasons -- which should be specified -- have one of these documents removed? Bill Jurens Yes: http://www.hmshood.org.uk/reference/official/adm234/adm234-509suff.htm and Leach's narrative a...

Unfortunately I've never seen long range data of dispersion for any of the ships - only that the British noted VV's dispersion to be particularly bad at Gaudo, while the same observations were not present in regards to her long-range shooting at Capo Teulada/Spartivento, or Littorio 's fire at eith...

"the battleship Littorio, while able to target the Caio Duilio with her rangefinders previously, this became impossible when the other battleship turned on her searchlights and blinded the Littorio. However, use of 'Zeiss-Septar' polarizing filters made it possible to target the other battleship wi...

Here's the crest:
