[6] The primary armament of the Tribal-class destroyers was eight quick-firing (QF) 4.7-inch (120 mm) Mark XII guns in four superfiring twin-gun mounts, one pair each fore and aft of the superstructure, designated 'A', 'B', 'X', and 'Y' from front to rear.

[11] To increase the firing arcs of the AA guns, the rear funnel was shortened and the mainmast was reduced to a short pole mast.

Following this, Nubian joined 14th Destroyer Flotilla at Plymouth, which was led by Captain P J Mack (temporarily flying his pennant in Janus, whilst has own ship, Jervis, was undergoing repair).

During the battle of Cape Matapan, she delivered the coup de grace to the Italian cruiser Pola, stricken by an aerial torpedo.

From January to May 1943 she participate in the Tunisian campaign, where Nubian along with other British destroyers sank the merchants D'Annunzio, Stromboli, Fauna and Campobasso.

[16] On 9 February, Nubian and Kelvin engaged three Italian schooners near the island of Kuriat, off Monastir,[16] but the small vessels managed to sail away unscathed by throwing blazing drums of fuel to the sea which then became the target of the British guns.

While in the Arctic she conducted convoy escort duty, during which she was involved in at least one direct attack on a U-boat, a cat and mouse hunt which lasted some days.

At the end of 1944, Nubian was refitted, ready to be dispatched to the Far East in March 1945 as part of the escort force of the 21st Aircraft Carrier Squadron, seeing action in support of the closing operations in Burma.
