PoW在丹麦海峡之战的炮术报告

丹麦海峡BSM的fumo也坏了，双方还真打了场原教旨的海战。双方25000-15000码之间的交战能力展现得很充分
不过之后24号傍晚18点-19点掩护欧根脱离和25号凌晨的第二和第三次接触，英德两国在30000码级别表现都比较糟糕，25号凌晨20000码即使有雷达辅助得到距离，但是由于敌舰烟雾，射击也无法持续。效果也不大，而且能见度不太好，看不到自己炮弹落点
丹麦海峡的纬度在5月底日照时间极长，夜里23点箭鱼都能像BSM发起攻击

24日2300时刻胜利号航母825中队拍摄的空袭BSM的照片，可见丹麦海峡此时光线还不错

第一场射击情况：典型的阶梯射抓距离，先射远再一点一点拉回，细节很丰富。还有海况、航行姿态对火控与火炮 ...

我觉得KGV第一次齐射不是故意打出远蛋的，根据英国30年代的远距离射击试验来看，15英尺的测距仪在25000码级别的测距精度在900码附近，第五次齐射才通过200码的ladder推到跨射是很正常的表现吧
英国确实忌讳一开始打远蛋，曾经分析过远蛋情况下可能观测不到蛋着点，连续出现wild shot，导致火控程序要推倒重来一次，并且提出了飞机校射是远战时纠正远蛋蛋着的很好的解决办法

俾斯麦首先向18km上的英国巡洋舰开火（当时英方最高指挥官坐镇巡洋舰），巡洋舰随后拉烟向PoW靠拢。俾斯麦 ...

第二次交战POW打了12次齐射41蛋，发射数量比第一次也就少了16发，而且交火时间达到12分钟，比第一次行动时间还长
按照DK Brown的说法，英国战列舰适用于在12000-18000码的决定性距离上KO对方的，整个战前进行过23000码以上射击试验的只有HOOD和两条老衲

BSM的第二场表现也很差，炮弹落点非常歪

还有一点很有趣
英国报告里还说在指挥仪里风太大，听不见传声筒里面传来的舰桥的指令。舰员想出来用“A direct sound power hand-set”来凑合，效果还不错，并推荐使用

英國佬窮瘋了，連一部備用的聲力電話也不肯裝？

F. - Notes on Own Ship's Gunnery

Application of Spotting Rules. - These were applied successfully in the T.S. during the first action.
Cross-levelling gear. - This was used throughout both the first and second actions with success.
A.F.C.T., Mk IX. - The 14-in. table was run continuously for 32 hours and proved most reliable. The only incidents which occurred were as follows:-
During the first action after firing salvo 12, a heavy hit was felt on the starboard side and the director setting mechanical pointer was seen to be oscillating violently. At the same time a fuze was noticed to blow at the panel in the 14-in. T.S. The director setting control trigger was used to move off the mechanical pointer. On release, the pointer settled in line with the indicator pointer and no further trouble was experienced.
Immediately after the third action, the safety diaphragm in the air supply to the motors, blew with a loud report and the T.S. was filled with blue smoke caused by vaporised oil in the air system. A double diaphragm was inserted to prevent recurrence.
Communications between Bridge and D.C.T. - Great difficulty was found in using the voicepipe communication with the high wind blowing past the director. A direct sound power hand-set has now been rigged by ship's staff and is recommended for future construction.
General remarks on the behaviour of the 14-in. Turrets - During the working up period numerous minor mechanical defects have been experienced in spite of unremitting efforts on the part of the Ordnance staff, and during the operations against Bismarck this state of affairs persisted.
In the circumstances the output achieved might well have been lower. That this was not so was due to the continual efforts of the Ordnance staff and with one exception, to good loading drill in the turrets.

The presence in each turret of one of Messrs. Vickers Armstrong's erecting staff was of the greatest assistance.

吴老请看英国总结的第四条，POW起码丹麦海峡是没有正式在指挥仪安装声力驱动的耳机电话的，是船员门自己想办法搞得
