Player Opinion

Cruiser - Rochester

Pros:

• Like Baltimore, Rochester uses superheavy AP shells with high penetration and improved penetration angles
• High shell arcs allow to shoot at enemy ships from behind island cover
• Access to the long-emission and long-duration Smoke Generatortypical of USN destroyers
• Access to Defensive AA Fireand Sonarin separate slots
• Good AA defenses
• Good speed at 33 knots unmodified (0.5 knots faster than Baltimore)
• Great concealment

Cons:

• Rather short main battery range
• Worse rate of fire than Baltimore
• High shell arcs make hitting targets at range difficult
• As with most USN cruisers, Rochester does not carry torpedoes
• Sluggish rudder shift
• Lacks the Radarconsumable
