HMS Unswerving (P63) was a Royal Navy U-class submarine built by Vickers-Armstrong. So far she has been the only ship of the Royal Navy to bear the name Unswerving.
Unswerving carried out work-ups at end of 1943, then joined the 1st Flotilla in the Mediterranean, where she carried out patrols in the Aegean Sea. She would eventually spend most of her wartime career in the Mediterranean, where she sank the German guardboats GN 61 and GN 62, the German tanker Bertha (the former French Bacchus) and six sailing vessels, and claimed to have damaged a seventh. She was however unlucky on numerous occasions, unsuccessfully attacking the small German merchant Toni (the former Greek Thalia), the German auxiliary minelayer Zeus, the German transport Pelikan and her escort, the German torpedo boat TA 19, and the German merchant Gertrud on two separate occasions.
Unswerving survived the war and was scrapped at Newport from 10 July 1946.
