Man the Guns replaces the existing naval technology system of set, successive designs with an extensive modular system that allows players to create more highly customized individual ship classes. Each ship has a number of slots for modules depending on its hull type, located above and below its portrait in the ship design screen. The bottom-side slots are considered fundamental mountings for the class and are universal to them, though some such as AA or Torpedoes need not be filled. For instance, all Destroyers have bottom-side mountings for one Battery Gun, one AA mount, a Fire Control/Sonar, a Sonar/Radar, a Torpedo Launcher, and an Engine. All ships also are required to have certain mountings -- a Destroyer, for instance, must have a Battery and an Engine, as otherwise it has no means to move or defend itself.
However, the mountings above the portrait are additional slots for customizing the class, and contain no mandatory elements. These are divided into three sections for the ship -- Front, Middle, and Rear, with up to two Front and Rear slots and three Middles ones. As an example, the Early Destroyer Hull only has one Middle and one Rear slot above-portrait, but the 1940 Destroyer Hull has a Middle, Rear, and Front.
Exactly what can go in the optional slots also changes from ship class to ship class. Cruisers and Battleships can only mount main guns or AA in their Front slots, but Destroyers can mount Depth Charges in theirs (as the 1940 technology bracket also unlocks the Depth Charge Mortar). A wide variety of equipment exists that can produce highly specialized ships.

Man the Guns replaces the existing naval technology system of set, successive designs with an extensive modular system that allows players to create more highly customized individual ship classes. Each ship has a number of slots for modules depending on its hull type, located above and below its portrait in the ship design screen. The bottom-side slots are considered fundamental mountings for the class and are universal to them, though some such as AA or Torpedoes need not be filled. For instance, all Destroyers have bottom-side mountings for one Battery Gun, one AA mount, a Fire Control/Sonar, a Sonar/Radar, a Torpedo Launcher, and an Engine. All ships also are required to have certain mountings -- a Destroyer, for instance, must have a Battery and an Engine, as otherwise it has no means to move or defend itself.

However, the mountings above the portrait are additional slots for customizing the class, and contain no mandatory elements. These are divided into three sections for the ship -- Front, Middle, and Rear, with up to two Front and Rear slots and three Middles ones. As an example, the Early Destroyer Hull only has one Middle and one Rear slot above-portrait, but the 1940 Destroyer Hull has a Middle, Rear, and Front.

Exactly what can go in the optional slots also changes from ship class to ship class. Cruisers and Battleships can only mount main guns or AA in their Front slots, but Destroyers can mount Depth Charges in theirs (as the 1940 technology bracket also unlocks the Depth Charge Mortar). A wide variety of equipment exists that can produce highly specialized ships.

未拥有 炮手就位 炮手就位的海军科技树

海军科技科技树解锁了新的舰船海军入侵的新科技。可以在科研界面中陆军学说海军学说的选项卡之间找到。海军科技树上有31种不同的科技,28级不同的舰船,其分为了7种类型,另外还有3个海运科技。请注意,第一种海军运输科技运输船,是执行海军入侵所必需的。还要注意的是,舰船的肖像上有一颗蓝色的钻石,表示它是一艘主力舰。主力舰设计用于在水面战斗中击沉敌舰,除了航母是通过其搭载的近距离空中支援机(CAS)提供轰炸外,其余的主力舰可以进行对岸炮击。

驱逐舰

最小型的屏卫舰,屏卫效率十分重要,因为主力舰需要在屏卫舰的保护下免受敌方小型舰艇鱼雷侵害(鱼雷虽然命中率低,但是击中后能对大型舰艇造成严重伤害)。驱逐舰是廉价的屏卫舰,可以躲避大口径火力,增加防空能力,并让您侦察和对抗潜艇。

巡洋舰

轻型巡洋舰是一种轻型屏卫舰。它擅长于消灭其他屏卫舰,其主要职责是保护主力舰不受到敌军舰队中携带鱼雷的轻型舰船的攻击,但轻型巡洋舰也能发射威力强大的鱼雷,如果它们离得足够近的话,能够伤害到大型舰船。

重型巡洋舰是一种非常灵活的装甲巡洋舰,对于那些无力建造大型主力舰的国家来说,这是一个不错的选择。重型巡洋舰可以承受大量的攻击并携带大量的火力。

潜艇

潜艇的作用是追捕敌方舰船,而不必直接挑战敌方的强大舰队来伤害他们。潜艇使用隐形和强大的鱼雷摧毁敌人的运输船队。如果敌人对潜艇的探测能力较低,潜艇也可以在常规舰队战斗中发挥作用。潜艇在战斗开始会隐藏起来,并在它接近驱逐舰或发射鱼雷后,它将试图逃脱并隐藏。在对付一个屏卫效率良好的舰队时,它不会是一个有效的武器,但无人保护的主力舰不会有太多的防御。

潜艇的目标主要是通过袭击运输船来打压敌人的经济水平。例如:

  • 攻击敌人贸易路线上的运输船队将使他们失去外国的资源。
  • 像英国这样在全球各地拥有领地的国家,必须从帝国的许多地方将本国资源护送到首都地区加以利用,这便使它们容易受到潜艇袭击。
  • 当接受租借装备时,运送装备的运输船队可能会被击沉,并将永远消失。
  • 在海外战场部署陆军部队时,一个国家必须向其处运送补给和补充装备。通过击沉这些运输船队,他们的部队将变得更弱,更容易被打败。
  • 正在运送或计划海军入侵的陆军部队可能受到潜艇攻击,导致部队被消灭或严重削弱。在战争时期派军队去某地之前,您总是要非常小心,保护好您的运输路线。
