The Killer class destroyer is an improved version of the American Allen Sumner class destroyer in the 1940s, but with a slightly larger size.
A total of 105 ships of this class were built from 1945 to 1949, 42 of which were completed before the end of World War II, but it was too late to show their skills on the Pacific battlefield. In addition, more than 50 ships were cancelled.
After the end of World War II, a large number of ships were reclassified as DDE, DDK, DDR, and EDD, and the "Kiat" was changed to DDG, becoming the first missile destroyer in the United States. Many "Keeling" grades were modified by FRAM I / II in the 1960s and were not retired until the early 1980s. A large part of them were transferred to the navies of other countries and are still active at sea.

The destroyer I copied was versatile. Buttons 1 and 2 can be used for No. 1 and No. 2 turrets, and button 3 can be used for No. 3 turrets. Button 4 can use a torpedo launcher, and button 7 can make 10 torpedoes volley. Button 5 can use all anti-aircraft weapons. The only disadvantage is that the guns cannot be air-defense.
