HMS B1 was the lead boat of the Royal Navy's B class of submarines.
She was originally to have been called A14 but was renamed B1 on completion,[1] the B class merely being larger and faster versions of the A class, with greatly improved underwater range and fitted with Vickers rather than Wolseley petrol engines.
She was built at Vickers, Barrow-in-Furness and launched on 25 October 1904. She was too primitive to be of much use in World War I and was quickly relegated to training duties. She was sold for scrap in May 1921.
