This luck would continue, when on the 19th of may 1943, during a operation at the rear of a convoy southeast of Cape Farvel greenland Jed spotted another uboat. As a result of this chase german uboat u-438 was destroyed by pelican.

On may 6th of 1943, as part of a convoy assigment in the western approaches, Jed along with HMS Pelican detected a submarine by radar and began a pursuit. Her initial service performing convoy escort would be uneventful, as she was assigned to the 1st escort group protecting shipping across the north atlatic. She would be launched on the 30th of july 1942, and would be commissioned on the 30th of november that same year, as the second royal navy ship to be named in honour of the river Jed. HMS Jed was ordered from Charles Hill & Sons Ltd, Bristol on the 11th of febuary 1941, and would be laid down on the 27th of Febuary that same year. the design would prove so successful, that the River-class design was used as the basis for the United States Navy’s Tacoma class (which served in the Royal Navy as the Colony class) the hull design was later elaborated into the Loch class and subsequently the Bay class. Another change was a better armament layout designed specifically to combat u-boats, including a Hedgehog anti-submarine mortar along with a copious amount of depth charge throwers, in addition to two QF 4 in (102 mm)/40 Mk.XIX guns, single mounts CP Mk.XXIII. Improvements made to the design, resulted in markedly better accommodation, along with an increased speed of around 3 knots (3 mph 6 km/h), along with a nearly doubling of range to 7,200 nmi (8,286 mi 13,334 km) at 12 knots (14 mph 22 km/h). the intents being to improve the convoy escort class of ships in service with the royal navy, including surpassing the existing flower-class. The river-class ships were designed by naval engineer William Reed, of Smith’s Dock Company of South Bank-on-Tees, with the intents of making a vessel with endurance and anti-submarine capabilities on par with the black swan-class sloops, but being significantly quicker and cheaper to build in civil dockyards using common machinery.This included reciporcating steam engines instead of the normal turbines, along with construction techniques pioneered by the flower-class corvettes.
