Seattle — U.S.A. Tech Tree Tier IX Cruiser.

During the early 1940s, the United States was actively involved in the development of new cruisers specifically designed to fulfill air-defense missions. They were to have 12 dual-purpose 152 mm guns, a speed of 33 knots, and a thick armor deck to protect against aerial bombs. After the outbreak of World War II, engineers were no longer bound by treaty constraints, although the ship's size was to remain within the limits of a light cruiser. The project never came to life, but its underlying concepts served as the basis for the subsequent design of the Worcester-class cruisers.

Pros

• High damage per minute
• Access to Defensive AA Fire, Hydroacoustic Search and Surveillance Radar consumables in separate slots
• Low detectability

Cons

• Low main battery range and ballistics
• Poor main battery firing angles
• Poor survivability
