HMS Arabis was a Flower-class corvette built for the Royal Navy as part of the 1939 War Emergency Programme. Constructed at Harland & Wolff in Belfast, she was ordered on September 19, 1939, laid down shortly thereafter, launched on February 14, 1940, and completed by April 5, 1940. Named after the flowering plant arabis, or rockcress, she was among the early vessels of her class. Arabis was primarily deployed as a convoy escort in the Western Approaches, where she performed essential duties such as protecting merchant ships, searching for and attacking U-boat threats, and rescuing survivors. Her service record includes participation in numerous convoy battles, notably escorting OB 216 in September 1940, which lost four ships; OB 229 in October 1940, losing two ships; and HX 79 the same month, which suffered the loss of twelve ships. She also contributed to the defense of HX 126 in May 1941, which lost seven ships, and HX 133 in June 1941, which saw six ships sunk and the destruction of a U-boat. Over her two years in the Atlantic, Arabis escorted 47 Atlantic convoys and 11 Gibraltar convoys, helping over 2,000 ships reach their destinations despite the persistent U-boat threat. In April 1942, while at Belfast, she was transferred to the United States Navy under the Reverse Lend-Lease agreement, becoming USS Saucy. During her US service, she escorted convoys to Halifax, Nova Scotia, underwent refitting in Boston, and operated between Trinidad and Barbados. Her routes included the Trinidad-Guantanamo Bay and Trinidad-Recife convoys. She returned to North Atlantic duties in March 1944 and was decommissioned from US service in August 1945 at Chatham, England. Following her decommissioning, she was recommissioned into the Royal Navy as HMS Snapdragon, and later sold in 1946. She served as the merchant vessel SS Katina, later renamed SS Tewfik in 1950, marking her varied maritime career beyond wartime service.
