HMS President (formerly HMS Saxifrage) is a retired Flower-class Q-ship that was launched in 1918. She was renamed HMS President in 1922 and moored permanently on the Thames as a Royal Navy Reserve drill ship. In 1982 she was sold to private owners and, having changed hands twice, served as a venue for conferences and functions as well as the offices for a number of media companies. She has been moved to Chatham on the Medway in Kent since 2016, but is due to return to the capital. She had the suffix "(1918)" added to her name in order to distinguish her from HMS President, the Royal Naval Reserve base in St Katharine Docks. She is one of the last three surviving Royal Navy warships of the First World War. She is also the sole representative of the first type of purpose built anti-submarine vessels, and is the ancestor of World War II convoy escort sloops, which evolved into modern anti-submarine frigates.
Design and construction
HMS President was built as an Anchusa-type . These were built between 1916 and 1918 as submarine hunters disguised to look like merchant ships, while carrying concealed 4-inch and 12-pounder naval guns. U-boats would dive at the sight of a naval warship, and the success of the Q-ships, or 'mystery ships' - converted merchantmen with hidden guns - led to the building of these specialised naval vessels for the same purpose. It was intended that a U-boat captain, unwilling to expend a precious torpedo on a small coastal merchantman, would surface to sink it by gunfire. As the submarine closed for the kill, the Q-ship would reveal her hidden guns and counterattack while the U-boat was at its most vulnerable on the surface. By the time the "warship-Qs" were constructed, the Germans were well aware of this tactic, and with the introduction of unrestricted submarine warfare these sloops became active rather than passive submarine chasers.
In the case of the warship-Qs the individual builders were asked to use their existing designs for merchantmen, based on the standard Flower type warship hull. This included a dummy merchant ship sternpost rudder, mounted above the waterline over a much more manoeuvrable balanced rudder which allowed the ship to make a fast turn to bring her guns or depth charges to bear on a U-boat, or even to ram it before it could escape.
The class were also given a wide variety of spectacular dazzle camouflage schemes to confuse the primitive range finders of World War I submarines. Altogether, 120 Flowers were built, of which eighteen were sunk in action during the war.
Saxifrage was built at the shipyard of Lobnitz & Company, Renfrew, Scotland, as yard number 827 and launched on 29 January 1918. She was named Saxifrage after the flower also known as London Pride.
Naval service
Active service
HMS Saxifrage escorted convoys in UK waters during 1918, and engaged nine U-boats, as recorded in her logbooks held in the National Archives at Kew. In 1922 she was permanently moored on the Thames, and renamed President. Other members of the class served as patrol vessels throughout the world during the peacetime years between the wars, but almost all were disposed of by the Second World War. This allowed the majority of the class names to be revived for the new, smaller s, including both Saxifrage and Chrysanthemum.
Reserve service
From 1922 she was employed as a Royal Naval Reserve drill ship, and as such was moored permanently on the Thames at Blackfriars. Her new name was inherited from the Old President of 1829, which had been based in West India Docks from 1862 to 1903 as the first London naval reserve drill ship. The 1918 President remained in Royal Navy service for a total of seventy years, from 1918 to 1988. She was the last Royal Navy warship to wear Victorian battleship livery of black hull, white superstructure and buff yellow funnel and masts. All naval personnel working at the Admiralty and elsewhere in London were nominally appointed to service in President, and they were paid and administered by her staff. MI6/SIS officers who had RN commissions were appointed to President, but paid and administered by the SIS.
During the Second World War President was converted to a gunnery training ship, fitted with a large overall "shed" superstructure. Her major role was the training of DEMS gunners for defensively equipped merchant ships. Her sister Flower class Q-ship, , was moored ahead of her in 1938 to provide additional office and training space.
