HMS Gnat was an Insect-class gunboat of the Royal Navy, constructed by Lobnitz and launched in 1915. Designed as a small, heavily armed vessel, she was primarily built for river and coastal operations. During World War I, Gnat participated in the Mesopotamian Campaign, operating on the Tigris and Euphrates rivers as part of a gunboat squadron, contributing to British efforts in the Middle East. Following the war, Gnat was transferred to China, where she played a notable role in the 1927 Nanking Incident, part of a Royal Navy flotilla tasked with protecting British and international interests amid tensions in China. She continued her service in the Far East until 1940, maintaining her presence on the China Station at the outbreak of World War II. In 1940, Gnat was towed from China to the Mediterranean Sea, where she joined the Mediterranean Fleet's Inshore Squadron. She supported the Allied assault on Tobruk in January 1941, along with other vessels such as Stuart, Vampire, Voyager, and Terror. During this operation, Gnat contributed to the port's capture by providing naval support to ground forces. On 21 October 1941, Gnat was torpedoed by the German submarine U-79. Although she did not sink, the damage was severe enough that she was beached at Alexandria, Egypt, and repurposed as a fixed anti-aircraft platform. Declared a constructive total loss, she remained in this role until the end of the war. Gnat was finally scrapped in 1945, marking the end of her distinguished service. Throughout her career, Gnat demonstrated versatility, serving in various theatres from the Middle East to the Mediterranean, and participating in significant military operations. Her service record reflects the strategic importance of small gunboats in riverine and coastal warfare during the early to mid-20th century.
