麻烦诸位推荐一本介绍八八舰队里那些未完成BB和BC的书

至少有过记录，证明水侦的照明弹可以在夜战中其作用。而且日本的巡洋舰都是1920s的

而美国方面没有任何记录证明可以在夜间用雷达打下飞机。如果雷达实际上不好用，那我不认为衣阿华在夜间和那些1931年的巡洋舰有什么区别。

谁说的? 这里就有个记录。
http://www.destroyerhistory.org/goldplater/warhistory417.html
Not many enemy planes were encountered but Morris brought down a snooper one night by the use of full radar control.
Morris防空火力可比衣阿华差远了。而且Morris上还没有象衣阿华有MK 57那样的尖端设备。

还有这个：
http://dd450.com/Destroyer_Squadron_21.html
USS RADFORD, DD 446 - Built alongside Fletcher at Kearny and first commissioned 22 July 1942, the fifth ship of the class. Initially assigned to antisubmarine patrols in the Atlantic, then fought her way through the Solomons campaign, including Kula Gulf and Kolombangara, without casualties. First ship in the navy to shoot down a plane at night without ever having seen it, using full radar control.

如果按照5、60年代时的数据，F-4的雷达可以让40公里内的米格-17无所遁形，也不会把米格-17误认为任何鸟类（或者反过来），然后麻雀将在米格-17还没有进 ...

越战时F4的雷达是可以探测到米格17的，只是识别是个大问题，这个问题其实先前一直被忽略了。当时理论也并不认为雷达能识别出40公里内的某飞机到底是敌是友，只是想当然的认为雷达一显示，麻雀一打，就完事了。。。似乎是压根没考虑到敌我识别的问题，越战许多美军飞行员都是到了该用响尾蛇的距离才辨出是敌机的。

About 7500 AIM-7D and 25000 AIM-7E missiles were built, and the Sparrow was used heavily in Vietnam by the USAF and the U.S. Navy. The first combat kill was scored on 7 June 1965, when USN F-4B Phantoms shot down 2 MiG-17s. However, the initial combat results were very disappointing. The potentially long range of the AIM-7 could not be used, because unreliable IFF capabilities of the time effectively required visual identification of all targets. Coupled with the high minimum range of the missile of 1500 m (5000 ft) and poor performance against manoeuvering and/or low-flying targets, this led to a kill probability of less than 10%.
不过衣阿华的情况嘛，大不了不出动那几架“海鹰”了。

突然发现马萨诸塞打让巴尔打了200发左右的炮弹只命中了5颗左右

“Joining the war at sea"一书写的是9次齐射和半齐射，都按齐射算才81。
http://www.daileyint.com/seawar/seawar6.htm
Jean Bart took some      heavy metal. Massachusetts unloaded 9 salvos, some with six guns firing some      with all nine firing. (depends on the bearing; not unusual for a maneuvering      ship to have a turret unable to fire because the firing cutout cams are      protecting the ship itself) According to Morison's account, one shell exploded      in an empty jean Bart magazine, one wrecked her after control station and      opened up a hole below the waterline. Two armor piercing shells hit but did      not meet enough resistance to explode, and a fifth shell hit a glancing blow      on the forward turret, causing the turret to lock up in train (no movement      possible in the horizontal plane) and putting her entire available battery      out for 48 hours.

200发是包括对岸轰击的炮弹。

Between 0704 and 0810 on November 8th the Massachusetts fired over 200 rounds at either the Jean Bart or the costal defense battery

呵呵多谢指正，是我记得不太详细，雷达设计还是考虑到这个问题的，只是实战中无法达到理论上的效果。实战中F4的雷达识别时间到了，战斗机也进入了可以犬斗的距离了。另外貌似早期的AIM7麻雀故障也有不少。

5/81=6%，这种命中率也不怎么高（当然了，和北卡打雾岛那个8000米9%的命中率比还是有点面子的），而且传说中的28km命中弹事实上只是22km命中的

怎么是传说呢？ 日志上写的，前面引了是29000码。
81发是上限，下限是6X9=54发。
萨沃日本战列舰主炮大和104发，金刚级360发，长门45发，打中了有6%吗？

thorongil

没有，原因是日本人打的是海战，而马萨诸塞打的是靶子
