誰能詳細介紹一下關於實戰的效果哪個更好？
Japanese
10 cm/65 (3.9") Type 98
Updated 26 August 2007
The best Japanese AAA gun of World War II, whose characteristics can only be described as "superb." Their only fault was a rather short service life, the result of high muzzle velocity and a fast rate of fire. In 1945, most new production mounts were diverted to shore-based installations.
There were two versions of the gun barrel. Model Type I used a radially expanded, removable lining while the Model Type I2 was of monobloc construction. Both types had breech rings and a horizontal sliding breech-block. Spring-operated, semi-automatic rammers, which were cocked by the recoil force, were mounted above the guns. These allowed the guns to be loaded at any angle of elevation, an important factor for any AA weapon. Shells were manually inserted into fuze setting machines before being placed into the loading trays.
A total of 169 guns were completed between 1940 and 1944 with 68 used in land mountings. All were in twin mounts.
12.7 cm/40 (5") Type 89
Updated 03 December 2008
The Type 88 was used only on two submarines in single mountings. The very similar Type 89 was an AAA weapon used in twin mountings on most World War II ships cruiser size and larger as well as on small destroyers. The Type 89 was also used to replace many of the 12 cm/45 (4.7") AA guns on older cruisers.
The Type 89 was a good AAA weapon with a fast rate of fire and excellent elevation and training speeds on the later Mods. Its primary shortcoming was a relatively low muzzle velocity and thus a short range and low AA ceiling.
These weapons were of simple construction with autofretted monobloc barrels and breech rings and used horizontal sliding breech-blocks. Total production of Type 89 guns amounted to 1,306 guns, with 836 being manufactured between 1941 and 1945. Of these, 362 were mounted ashore, including 96 in the Yokosuka area and 54 in the Kure area.
Unless otherwise specified, the data that follows is for the Type 89.
