HMS Firm was a 16-gun Firm-class floating battery built for the Royal Navy and launched in 1794. Designed by Sir John Henslow, the vessel was modeled after flat-bottomed Thames barges, specifically intended for operation in shallow waters. As a two-vessel class, the Firm was constructed to serve in coastal and riverine environments, emphasizing stability and maneuverability in shallow zones. The vessel's early service commenced in June 1794 under Commander Temple Hardy. Shortly thereafter, in September, Commander Robert Plampin took command, overseeing operations at Ostend and Flushing. In August 1795, command shifted to Commander John Edwards, who stationed her at Leith. She was paid off in February 1796 at Sheerness, indicating a period of decommissioning or reduced activity. Recommissioned in September 1796 under Commander Horace Pine, HMS Firm was stationed at Chatham to safeguard the River Medway. During the significant Spithead and Nore mutinies in June 1797, the vessel was at Shellness. Notably, during these events, the mutiny's ringleader, Richard Parker, attempted to seize control of her by placing a man, Thomas Appleyard, aboard. However, the crew did not join the mutiny, and HMS Firm sailed to Sheerness, anchoring near the Half Moon Battery and Grain Spit to prepare for potential action against the mutineers. Appleyard was later court-martialed and hanged aboard the vessel at Gillingham Reach, underscoring her role in maintaining order during this turbulent period. In June 1798, command was transferred to Commander Patrick Campbell. By August 1799, Bulkeley Mackworth Praed, recently released from enemy custody, was promoted to Commander of HMS Firm. She continued her service in the Channel, remaining at Sheerness from March 1800 with Praed in command. The vessel was paid off in March 1802, shortly before Praed was promoted to post captain on 29 April 1802. HMS Firm was sold on 30 March 1803 for £525 to Mr. F. Hurry, marking the end of her naval service. Her design and operational history highlight her role as a shallow-water platform during a tumultuous period in Royal Navy history, particularly in coastal defense and anti-mutiny operations.
