Helena — U.S.A. Tech Tree Tier VII Cruiser.

The Brooklyn-class design, based on the hull of cruiser New Orleans, was developed taking into account the limitations of the London Naval Treaty and the characteristics of the Mogami class under construction in Japan. Later, two cruisers of an improved design were ordered, one of which was USS Helena. At the beginning of World War II, she served in the Pacific Ocean. Helena sustained damage during the raid on Pearl Harbor but went on to take part in significant engagements such as the Battle of Cape Esperance and the fighting at Guadalcanal; however, the ship was ultimately lost on July 6, 1943, during the Battle of Kula Gulf.

Pros
