Heavily armed merchant ships with concealed weaponry

Q ships, also known as Q boats, decoy vessels, special service ships, or mystery ships, were heavily armed merchant ships with concealed weaponry, designed to lure submarines into making surface attacks. This gave Q ships the chance to open fire and sink them. They were used by the British Royal Navy and the German Kaiserliche Marine during the First World War and by the Royal Navy, the Kriegsmarine, the Imperial Japanese Navy, and the United States Navy during the Second World War (1939–45). Though legally recognised as an acceptable tactic of military deception, they have attracted much controversy, enjoying only marginal success during WWI and none in WWII.

Short for Queenstown in Ireland, as Haulbowline Dockyard in Cork Harbour was responsible for the conversion of many mercantile steamers to armed decoy ships in World War One, although the majority appear to have been converted in larger navy yards such as Devonport.

The general idea and legal framework for the Q ship derives from the classic ruse de guerre of "sailing under false colours". As a long standing element of naval tactics, warships may legally disguise themselves in various ways in transit, so long as the proper flags are hoisted before firing commences. Numerous examples exist of the tactic, used both defensively and offensively. Examples of the tactic used against commerce raiders include in the 1670s and French disguised brigs during the French Revolutionary Wars. An example of the latter was beaten back by the privateer lugger Vulture out of Jersey.

In 1915, during the First Battle of the Atlantic, Britain was in desperate need of a countermeasure against the U boats that were strangling its sea lanes. Convoys, which had proved effective in earlier times (and would again prove effective during the Second World War), were rejected by the resource strapped Admiralty and the independent captains. Depth charges of the time were relatively primitive, and almost the only chance of sinking a submarine was by gunfire or by ramming while on the surface. The problem was how to lure the U boat to the surface. A solution to this was the creation of the Q ship, one of the most closely guarded secrets of the war. Their codename referred to the vessels' home port, Queenstown, in Ireland. These became known by the Germans as a U Boot Falle ("U boat trap"). A Q ship would appear to be an easy target, but in fact carried hidden armaments. A typical Q ship might resemble a tramp steamer sailing alone in an area where a U boat was reported to be operating. Torpedoes were expensive, and a submarine only carried a limited number of them, ideally employed when the vessel is submerged and invisible to her target. Ammunition for a deck gun, oppositely, was inexpensive and plentiful in comparison. As a result, submarine captains preferred to surface and use their deck gun on easy or already weakened targets. By seeming to be a suitable target for the U boat's deck gun, a Q ship was intended to lure a submarine into surfacing. Once the U boat was vulnerable, perhaps even gulled further by pretence of some crew dressed as civilian mariners "abandoning ship" and taking to a boat, the Q ship would drop its panels and immediately open fire with its deck guns. At the same time, the vessel would reveal her true colours by raising the White Ensign (Royal Navy flag). When successfully fooled, a U boat could quickly become overwhelmed by several guns to its one, or defer from firing and try to submerge before it became mortally wounded. The first Q ship victory was on 23 June 1915, when the submarine , cooperating with the decoy vessel Taranaki, sank off Eyemouth. The first victory by an unassisted Q ship came on 24 July 1915 when Prince Charles sank The civilian crew of Prince Charles received a cash award. The following month an even smaller converted fishing trawler renamed HM Armed Smack Inverlyon successfully destroyed near Great Yarmouth. Inverlyon was an unpowered sailing ship fitted with a small 3 pounder (47 mm) gun. The British crew fired nine rounds from their 3 pounder into UB 4 at close range, sinking her with the loss of all hands despite the attempt of Inverlyons commander to rescue one surviving German submariner. On 19 August 1915, sank , which was preparing to attack the nearby merchant ship Nicosian. About a dozen of the U boat sailors survived and swam towards the merchant ship. The commanding officer, allegedly fearing that they might scuttle her, ordered the survivors to be shot in the water and sent a boarding party to kill all who had made it aboard. This became known as the "Baralong incident". (Q.5) sank on 22 March 1916. Her commander, Gordon Campbell, was awarded the Victoria Cross (VC). New Zealanders Lieutenant Andrew Dougall Blair and Sub Lieutenant William Edward Sanders faced three U boats simultaneously in Helgoland (Q.17) while becalmed and without engines or wireless. Forced to return fire early, they managed to sink one U boat and avoid two torpedo attacks. Sanders was promoted to lieutenant commander, eventually commanding the topsail schooner in command of which he was awarded the Victoria Cross for an action on 30 April 1917 with , which was severely damaged. Helgoland, while the ship sustained heavy shellfire, waited until the submarine was within , whereupon he hoisted the White Ensign and Prize opened fire. The submarine appeared to sink and he claimed a victory. However, the badly damaged submarine managed to struggle back to port. With his ship accurately described by the survivors of U 93, Sanders and his crewmen were all killed in action when they attempted a surprise attack on on 14 August 1917. According to Warships of World War I by H. M. LeFleming, the Royal Navy converted 58 from merchant ships (18 were sunk by U boats), in addition to 40 and 20 PC boats. However Conway's All the World's Fighting Ships 1906–1921 quotes no fewer than 157 named submarine decoy vessels converted from other types of ship, in addition to another ten whose name was unknown. It agrees with LeFleming about the number of sloops and PC boats. These ones were completed as Q ships, disguised as coastal freighters and differed from regular service PC boats. None were lost in the war. The Flower class sloops were designed on merchant ship lines thus making them easily adaptable for conversion to Q ships, 39 being completed as such while the other was converted after being torpedoed. These all had single funnels, and as the merchant ship silhouette was left to the builders. The "Flower Q's" were employed mainly on convoy and anti submarine work. Nine were lost during the war. After the war, it was concluded that Q ships were greatly overrated, diverting skilled seamen from other duties without sinking enough U boats to justify the strategy. Estimates differ due to the uncertainty of the attribution of lost submarines, but in a total of approximately 150 engagements, British Q ships destroyed or assisted in the loss of around 12 15 U boats and damaged 60, at a cost of 27 38 Q ships lost out of ~200. Q ships were thus responsible for under 10% of all U boats sunk, ranking them well below the use of ordinary minefields in effectiveness. Around half of Q ship successes took place in June to September 1915, after which the ships were much less effective. With the second round of unrestricted submarine warfare in 1917, Q ships sunk only 3 submarines, dwarfed by the ~28 sunk by undisguised warships.

The Imperial German Navy commissioned six Q boats during the Great War for the Baltic Sea into the Handelsschutzflottille. None were successful in destroying enemy submarines. The German Q ship Schiff K heavily damaged the Russian submarine Gepard of the on 27 May 1916. The famous Möwe and Wolf were merchant raiders, vessels designed to disrupt enemy trade and sink merchantmen, rather than attack enemy warships.

Germany employed at least 13 Q ships, including the Schürbeck which sank the British submarine The German German auxiliary cruiser Atlantis, which sank a number of ships with a total tonnage of 145,960 t including the Norwegian tanker Tirranna on 10 June 1940, was more of a merchant raider.

The Imperial Japanese Navy converted the 2,205 ton merchant ship, Delhi Maru, into a Q ship. On 15 January 1944, she departed from Nagaura (now Sodegaura on Tokyo Bay) on her first mission in company with the submarine chaser Ch 50 and the netlayer Tatu Maru. At 22:00 that evening, the vessels were detected by the submarine Swordfish, which launched three torpedoes. Delhi Maru was hit by all three on her port bow; following a number of internal explosions, she broke in two, the forward section sinking immediately and the aft section sinking later in heavy seas. Although Swordfish was depth charged by Ch 50, she escaped unscathed.

Attacks on merchant ships by pirates originating on the Somalia coast have brought suggestions from some security experts that Q ships be used again to tempt pirates into attacking a well defended ship.

A surviving example of the Q ships is HMS Saxifrage, a Flower class sloop of the Anchusa group completed in 1918. She was renamed in 1922 and served as the London Division RNR drill ship until 1988, when she was sold privately and remains moored at King's Reach on the Thames.

The Alfred Noyes poem "Kilmeny" is about a Q ship, a British trawler equipped with two deck guns, that destroys a German submarine during World War I. In Ernest Hemingway's novel Islands in the Stream, the main character Thomas Hudson commands a Q ship for the US Navy around Cuba as he hunts the survivors of a sunken German U boat. In Edward L. Beach Jr.'s novel Run Silent, Run Deep, Japanese Q ships make two appearances with one surprising the Walrus and the second being attacked by the Eel in the final battle of the story. Malcolm Lowry's novel Under the Volcano (1947) tells the story of Geoffrey Firmin, an alcoholic British consul in the small Mexican town of Quauhnahuac, on the Day of the Dead, 2 November 1938. Geoffrey Firmin reflects back to his time as a naval officer during World War I, when he was court martialed and subsequently decorated for his actions aboard a Q ship (the captured German officers disappeared and were allegedly burned alive in the boiler). In the Clive Cussler book series Oregon Files, the main base of operations is a Q ship, a converted lumber carrier. The crew are mercenaries and former US covert and military personnel who carry out missions around the world in support of US policy while earning their living performing mercenary operations. The 1951 movie Operation Pacific features a battle with a Q Ship by the fictional submarine USS Thunderfish, inspired by an encounter with an enemy ship by the USS Growler.
