USS Monadnock, a 3990-ton monitor, was built over a 22-year period at Vallejo and Mare Island, California, finally commissioning in February 1896. During the next two years, she served with the Pacific Squadron in the U.S. west coast area. In June 1898, she departed San Francisco on a two-month voyage to the Philippines, where she was needed to provide heavy-gun support following Admiral Dewey's victory at Manila Bay.

Monadnock remained in the Far East to the end of her career, serving in Philippine and Chinese waters. She decommissioned for the last time in March 1919 and was sold in August 1923.
