As a weapon, Congreve rockets remained in regular use until the 1850s, when they were superseded by the improved spinning design of William Hale. In the 1870s, Congreve rockets were used to carry rescue lines to vessels in distress, gradually superseding the mortar of Captain Manby that had been in operation from 1808 and rockets designed by John Dennett (1780–1852) that had been deployed in the late 1820s. These were first used to carry out a rescue in 1832 and used in the Irex rescue as late as 1890.
