DL-1 Charles/查尔斯级驱逐领舰
【原型为美国海军米切尔级驱逐领舰，接下来的叙述以《北冰洋往事》为主】
从二战后，美国海军就考虑发展后续的驱逐舰。基林似乎是两者兼得的发展极限，而后面的驱逐舰面临的是鱼雷和火炮的抉择。但我们现在都明白，历史的选择是火炮。
当然正当犹豫不决的时候，CL-154计划中一个产物：Mk.18 127/52自动舰炮 进入了海军的视野内。这型舰炮的射速是每分钟60RPM（即每分钟射速60发，装填1s），远超Mk12的20RPM 。不过此炮为了达成极高的射速，造成其成本高昂且对电力需求更高，对于战后的美国海军来说列装此炮也没多大意义：反正基林就摆在那边，没有什么比基林还好了。
但北极战役爆发后，美国海军发现因为投射量问题，很多驱逐舰都无法用自己的投射来击沉敌舰，而鱼雷也因为目标移动速度过快而命中率堪忧。这个时候投射量的需求就体现了出来，给驱逐舰换装更加强大的舰炮势在必行。
也因为战争期间军费充足，海军要求这型驱逐舰可以上最多三座这样的舰炮。设计局的人也偷懒，给米切尔改了装甲及武备，然后扔出去等报酬了。最后的结果是海军采纳了此驱逐舰，并进行量产，补足前线损失的驱逐舰和轻巡洋舰。
该舰为米切尔级驱逐领舰首舰，参加北极战役后继续服役至1975年，退役封存后于1985年拆解。
[The prototype is the US Navy Mitchell-class destroyer, and the next narrative is based on "Once Upon a Time in the Arctic Ocean"]
Since World War II, the U.S. Navy has considered the development of subsequent destroyers. Keeling seemed to be the limit of both, and the destroyers behind them faced a torpedo and artillery choice. But we all now understand that the choice of history is artillery.
Of course, just as he hesitated, a product of the CL-154 program: the Mk.18 127/52 automatic naval gun, came into the Navy’s field of vision. The rate of fire of this naval gun is 60 RPM per minute (that is, 60 rounds per minute, 1s loading), far exceeding the Mk12’s 20 RPM. However, in order to achieve a very high rate of fire, the gun was costly and had a higher demand for electricity, and it did not make much sense for the post-war U.S. Navy to install this gun: Killeen was over there anyway, and nothing was better than Keeling.
However, after the outbreak of the Arctic Campaign, the U.S. Navy found that because of the problem of projection, many destroyers could not use their own projections to sink enemy ships, and torpedoes were also worried about the hit rate because the target moved too fast. At this time, the demand for projection is reflected, and it is imperative to replace the destroyer with more powerful naval guns.
Also because of the abundant military expenses during the war, the Navy required that this type of destroyer could have up to three such naval guns. The people of the Design Bureau were also lazy, and changed Mitchell’s armor and armaments, and then threw it out to wait for the reward. The end result was that the Navy adopted the destroyer and mass-produced it to make up for the loss of destroyers and light cruisers on the front line.
The ship, the first Mitchell-class destroyer ship, continued to serve until 1975 after participating in the Arctic Campaign, and was dismantled in 1985 after being decommissioned.
