![]() The senator said he was “heartened to see that this latest incursion was met with four U.S. “Given that our response was tepid, I strongly encouraged senior military leaders to be ready with a much more robust response should such another joint Chinese/Russian naval operation occur off our coast,” Mr. Sullivan said he received a classified briefing on the warships and noted that a similar operation was conducted off the Alaskan coast last year. John Roberts' "British warships of the second world war" has official plans of Southamptons, Leanders and Arethusas to check if anyone has it, but you will be measuring distances of about 1cm.Mr. The numbers are very rough, but it gives an idea. Then Rsquared is about 121 + 27 = 148 R is about 12 and the triple turret is about 24 ft diameter, or up about 10% on the twin. Then for a 6in L/45, 2r is about 22ft, put r = 11 Suppose the twin turret diameter is about the same as the barrel length. Īssume L = 6 then Rsquared - rsquared = Lsquared - (L/2)squared = 36 - 9 =27 Length needed for the recoiling gun is 2x in both turrets This distance (all things, especially the gun, being equal) will be the same in both triple and twin turrets, so the twin turret barbette can be smaller.ĭraw the diagrams: gun separation L in both turrets, gun offset from centreline is L in the triple of radius R, L/2 in twin of radius r. What fixes the minimum barbette size is the distance needed to accommodate the recoiling gun between the forward and rear points where the straight line along the gun meets the circular barbette. Assuming that the gun separation can be the same, in a twin the guns both lie on lines only 3ft from the centreline. That means the outer guns lie on lines 6ft from the centreline. IIRC the distance between the guns in a RN 6in triple was about 6ft. Lots of interesting pictures, but it is not easy to see what is happening unless you look at a plan view. Post subject: Re: Does barbette size shrink when gun number goes down? Note on how far down the gun elevate on this one: The Barbette have to fit the recoil of the guns. ![]()
