HMS Grasshopper was a Dragonfly-class river gunboat constructed for the Royal Navy in the late 1930s. Displacing approximately 585 long tons (594 metric tons) at standard load and up to 685 long tons (696 metric tons) at deep load, the vessel measured 196 feet 6 inches (59.9 meters) in length, with a beam of 33 feet (10.1 meters) and a draught of 6 feet 3 inches (1.9 meters). Its propulsion system consisted of Parsons geared steam turbines powered by two Admiralty 3-drum boilers, producing 3,800 shaft horsepower, which enabled a maximum speed of 17 knots (31 km/h). The ship could carry up to 90 long tons (91 metric tons) of fuel oil, supporting its operational range. The armament comprised two 4-inch Mk V quick-firing guns mounted fore and aft, each with a maximum elevation of +30 degrees, and a single 3.7-inch QF howitzer for versatile artillery support. Anti-aircraft defenses included eight .303-inch (7.7 mm) machine guns mounted singly. The crew numbered around 74 officers and ratings, reflecting its role as a river gunboat designed for patrol and combat in inland waterways. Constructed by John I. Thornycroft & Company at Woolston, Southampton, HMS Grasshopper was laid down on 29 December 1937 and launched on 19 January 1939. She was commissioned on 1 June 1939 in Hong Kong, where she was deployed to the Yangtse River, replacing the Insect-class gunboat HMS Gnat. Her service on the China station involved patrol duties until the outbreak of World War II, after which she was transferred to Singapore. During early 1942, HMS Grasshopper participated in the Malayan Campaign, notably aiding in the rescue of nearly 3,000 soldiers from the British 53rd Infantry and Indian Brigades. As Japanese forces advanced, she evacuated from Singapore on 13 February 1942 alongside her sister ship HMS Dragonfly. While en route, she was attacked by Japanese aircraft and was hit twice, setting her on fire and leading to her abandonment. Survivors were evacuated to Sebayer Island, and later managed to escape through treacherous jungle routes to reach Sumatra, demonstrating her role in the broader context of naval operations and evacuations during the early Pacific War.
