IBM-3“开拓者”号战列巡洋舰

继IBM-2的成功建造之后，木卫二联盟确定了新一代军用潜艇的技战术水平。鉴于实验性导航控制台尚未通过定型试验，联盟依旧在IBM-3上面确定使用旧型号的潜艇控制系统，并且对其作出了较多的改进：基于IBM-2舰员反应的潜艇手动操作很难悬浮不动的情况，IBM-3搭载了一台简易但是很有效的自动悬浮装置。利用IBM-2上的纯手动车钟改进出了自动定速的车钟，半自动化的控制系统极大的减轻了船员的 操作难度，也是让IBM-3成为一条真正可战的攻击潜艇的重要技术突破。事实上，正是因为解决了这些技术难题，IBM-3才能被确定为一条攻击潜艇，并作为木卫二联盟的第一条主力攻击潜艇服役，她重甲重炮以及优良的分舱抗沉设计深刻的影响了了联盟接下来数批主力战舰的设计与建造。

不过最终，IBM-3本舰在服役12年后为了解救科研船而战沉在了浩瀚渊洋，全舰十六人无一人生还。

Following the successful construction of the IBM-2, the Europa Alliance established the technical and tactical capabilities of a new generation of military submarines. Given that the experimental navigation console has not yet passed the prototype test, the alliance is still committed to using the older version of the submarine control system on the IBM-3, and it has made more improvements: based on the IBM-2 crew response submarine manual operation is difficult to hover motionless, IBM-3 carried a simple but very effective automatic suspension device. Using the purely manual clock on the IBM-2, the automatic speed-fixing clock was improved. The semi-automatic control system greatly reduced the operational difficulty of the crew, it was also a major technological breakthrough that made the Ibm-3 a truly operational attack submarine. In fact, by solving these technical problems, the IBM-3 was identified as an attack submarine and entered service as the Europa Alliance's first major attack submarine, her heavy armor and superior subdivision anti-sinking design had a profound impact on the design and construction of several of the alliance's next major warships.

But in the end, after 12 years of service, the Ibm-3 went down in the middle of the ocean to rescue the research vessel. None of the 16 people on board survived.
