HMS Revenge 1916 & aircraft
While trying to get a better view of a WWI era
British RN BB gun turret, I found: http://upload.wikimedia.org/wikipedi...le_drawing.png IMHO a nice set of color line drawings! OK, not that unusual, both the top (front and rear) main gun turrets, have wood planking constructed to enable a bi-plane to take off. OK, at ship top speed, & bit of a breeze, the plane could take off, & give scouting capability (& perhaps if all was worked up very well with a wireless, maybe even spotting capability,, although noting, even in 1939&40 that often did not go all that well,,). Question #1, under non-combat conditions could the bi-plane generally land safely on that platform? (Hey, ISTM, if the battle fleet is engaged & firing, the least important concern is aircraft recovery, when out of gas, ditch near a DD & hitch hike home.) Question #2, when the main guns elevated & fired, how much of that scaffolding fell off? Or, was it planned to quickly dismantle & cast overboard? Question #3A (while I have someone looking at this drawing ((??)) I may as well ask a more ignorant question) Go up the main front mast. There is here, & routinely, a large 'spar' that sits horizontal, and atwartship (90 degrees to ship centerline). I've long believed it to be a optical rangefinder. http://en.wikipedia.org/wiki/Coincidence_rangefinder But I can not find pictures of it at an angle (or aimed toward a broadside target) Is it an optical rangefinder, or just a spar? #3B, if that is not an optical rangefinder, where is the rangefinder? #3C, where does the primary gunfire director crew sit/work? |

(Hey, ISTM, if the battle fleet is engaged & firing, the least important concern is aircraft recovery, when out of gas, ditch near a DD & hitch hike home.) A normal approach to the front platform is quite impossible since there is superstructure behind it. (Though theoretically possible if the ship quartered into a headwind and aligned the turret with the apparent wind. It would take a super-pilot, and any error would douse the ship with burning gasoline. Therefore, I just don't think it happened.) The rear platform also doesn't seem to be designed for a landing. For half it's length, there is no place for the tail wheel! Imagine how turbulent the air would be behind the ship from the superstructure and the stack-gasses. My guess is that the planes normally landed on an airstrip for exercises and were intended to be sacrificed in case of actual combat. Also, note that the Captain wouldn't want that gasoline-filled plane on his deck during combat. Those flammable platforms also look like a danger. |

Just aft of "B" turret is a small turret-like structure with two ports on the front - that's the Director Control Tower. The Range Finder is the rectangular structure across the back of this. There is a similar but smaller backup installation just forward of "X" turret, a conning tower with a smaller rangefinder on the roof. Cheers, Moramarth |

Would you care to look at this one & offer info.? http://en.wikipedia.org/wiki/File:HM...le_drawing.png Probably one generation earlier (or, the first modern battleship). I would believe I see the primary gunfire control director station just forward of the rear stack. (with rangefinder). If that is correct, how many men do you figure sat inside that station? (For what it's worth, I believe I have a somewhat 'decent' understanding of WWII era BB & cruiser, and newer DD gunfire directors.) |

As built Dreadnought had two control positions, one on top of the foremast and another on the roof of the signal tower. Each had a 9ft Barr and Stroud rangefinder and fed them to a mechanical computer and range clock in the control position below them. Later extra rangefinders were fitted to the compass platform and to A turret and fire control refitted with a Dreyer Table The foretop crew would be relatively small. Keith |

I had thought they came later, but, on looking it up I find that 'range clock' first referred to what later became 'fire control clock', the name 'range clock' having apparently been taken over by the big dials mounted on capital ships post-Jutland to show gun elevation to ships ahead and astern. (If anyone has the details I'd be interested.) Peter |
