The Alert-class gunboat was a series of three propeller-driven iron gunboats operated by the US Navy in the late 19th century. The ships were ordered in 1873 when the Navy stalled technologically in the post-Civil War era. All commissioned by 1876, the ships served in various stations throughout the world. The next year, Huron was wrecked in a gale. By 1890, the remaining two ships were removed from distanced service and repurposed for other roles. The last in service, Ranger, was transferred to the Massachusetts Maritime Academy in 1940.
