The Pike-class refers to a series of submarines used by the United States Navy. These submarines were designed primarily for anti-submarine warfare and intelligence gathering during the Cold War era. They are known for their distinctive hull shape and advanced sonar systems, which enhance their stealth and detection capabilities. The class includes several variants, with the first submarine, the USS Pike (SS-173), commissioned in the late 1930s. Over the years, the Pike-class submarines have undergone various upgrades to improve their technology and operational effectiveness, making them a vital part of naval strategy during their service period.
