Wikipedia has a page called:

The U-Boat is a unique naval raider unit of the German civilization in Civilization VI. It replaces the Submarine.

In the Gathering Storm expansion, the U-Boat requires 1 Oil (Civ6) Oil to train and 1 Oil (Civ6) Oil per turn to maintain.

  • Attributes:
    • Lower Civ6Production Production cost (430 vs. 480).
    • Gains +1 sight and +10 Civ6StrengthIcon Combat Strength when fighting on Ocean tiles.
    • Able to reveal other invisible units.
    • Invisible except to City Centers, Encampments, Destroyers, other naval raiders, and units in an adjacent tile.
    • Can perform Coastal Raids.
    • Cannot attack in melee.


The U-Boat is a slightly cheaper version of the Submarine with a situational Civ6StrengthIcon Combat Strength bonus and the ability to reveal invisible units coming slightly earlier than a Destroyer. It is the weakest piece of the German arsenal - not because there's anything inherently wrong with it, but because it replaces a unit that doesn't come into play very often for a number of reasons and fixes none of the problems with this unit. (Read more here.) The U-Boat is a rather underwhelming unit overall, and in the expansions, German players will most likely build it only for the Era Score bonus unless the game takes place on a water-dominated map and they've slotted Letters of Marque.

Civilopedia entry Edit

The 'Unterseeboot' – U-boat – struck fear, and anger, in the hearts of Germany’s enemies during two world wars. The first German-built submarine, the 26-foot long Brandtaucher (“fire-diver”), sank during its initial test dive in the harbor at Kiel. This was followed by several submersibles built in Germany, which were sold to the Greeks, Ottomans, and Russians (all had rather ignominious careers). Finally the Germans got it right; the U-19 – they finally quit giving the boats names – was launched in 1912 with two-stroke diesel engines, four torpedo tubes and two deck guns, and able to dive to 164 feet. At the opening of WW1, Germany had 28 U-boats in service; in the first ten weeks, these sank five British cruisers. So effective were the U-boats that the Treaty of Versailles forbade the construction of German submarines. But, the U-boat fleet was rebuilt, and by the end of WW2 the boats had sunk some 2779 ships (confirmed) totaling 14.1 million tons – roughly 70% of Allied losses in all theaters. In 1955 West Germany was allowed to have a navy again ... and promptly started building U-boats, the latest being the non-nuclear U-35, commissioned in March 2015.
