Talk:Mackensen-class battlecruiser

Accuracy of the horsepower figure

I do not know what the correct horsepower is. However the number shown (85,000) is too low. The Farragut class destroyer leaders (DLG-6) of the US Navy produced 87,000 in a ship of only 5,800 tons for 32 knots. The battle cruiser would require far more than that.

I've got a copy of Groner's German Warships 1815-1945, I'll check it later tonight. It's probably correct though; Template:SMS had 63,000 shaft horsepower, for comparison. Parsecboy (talk) 22:12, 17 June 2009 (UTC)

Sorry it took me so long to reply here. Groner's does indeed give the figures as 90,000 shaft horsepower. The thing is, there were 4 shafts, so 90,000 on each shaft is quite a lot of horses. Parsecboy (talk) 12:02, 28 July 2009 (UTC)

Also, you require exponential increases in horsepower to achieve quite small increases in speed. The Iowas needed twice the horsepower of the South Dakotas (and a much finer hull) in order to realise a five knot increase in speed. 85,000 shp is about right for 28 knots in a 30,000 ton, four shaft ship.

Secondary Armament

The article states that the Mackensen class ships had a secondary battery of twelve 15 cm guns however the accompanying illustration clearly shows that there are seven 15 cm guns mounted along the starboard side. Since there would have been an equal number of secondary guns on the opposite side it would appear that these ships actually mounted a secondary armament of fourteen guns. — Preceding unsigned comment added by 108.26.84.169 (talk) 11:57, 28 April 2013 (UTC)

It's just a typo in the infobox - the text has the correct number. Thanks for pointing it out. Parsecboy (talk) 17:33, 28 April 2013 (UTC)

FAC link broken

And I really don't see how... Adam Cuerden ^(talk) 21:01, 23 January 2015 (UTC)

Somehow when the article history was updated, the DYK line got spliced. Should be good now. Thanks for catching this Adam. Parsecboy (talk) 21:23, 23 January 2015 (UTC)

Was setting up the Signpost Featured content report. Makes it pretty obvious when your method of doing so is "open all articles in the weekly list, click to talk page of each, go back to start, click to FAC to get needed information." (That's simplified slightly - I also check for good images and such. MUST be something good. Give me the dates of major engagements. I'll check that book I have. I mean, I know it has Scharnhorst.

Fluid drive

Under "Machinery" we've got this: "The turbines mounted in Fürst Bismarck were equipped with Föttinger fluid transmission, while those on the other three ships were two sets of direct-coupled turbines with geared transmissions." Then this: "The ships' turbines were equipped with Föttinger gears..." Assuming "Föttinger gears" means fluid drive, these seem contradictory. Kendall-K1 (talk) 12:56, 5 November 2015 (UTC)

I'll have a look at Hildebrand et. al. later today and get some clarification. Thanks for pointing it out. Parsecboy (talk) 13:00, 5 November 2015 (UTC)
