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.
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. [1] [2]
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. [3]
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. [2]
Examples of the tactic used against commerce raiders include HMS Kingfisher 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. [4] : 183
In 1915, during the First Battle of the Atlantic, Britain was in need of a countermeasure against the U-boats that were harassing 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 would only start to become available at the start of 1916, and so almost the only chance of sinking a submarine was by gunfire or by ramming while on the surface.
Submarines could attack by torpedo or by deck gun. Torpedoes can be used while the vessel is submerged and invisible to her target, while deck guns are used on the surface. Torpedoes were expensive, unreliable, and a submarine only carried a limited number of them. 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 most targets. However, when encountering a warship, submarine commanders could recognise the threat they posed and use a torpedo, or simply not engage.
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. [5] These became known by the Germans as a U-Boot-Falle ("U-boat trap"). A Q-ship would appear to be an unarmed merchant ship and so an easy target, but in fact were warships that 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.
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 to attack. 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 HMS C24, cooperating with the decoy vessel Taranaki, sank U-40 off Eyemouth. The first victory by an unassisted Q-ship came on 24 July 1915 when Prince Charles sank U-36. 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 UB-4 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 Inverlyon's commander to rescue one surviving German submariner.
On 19 August 1915, HMS Baralong sank U-27, 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".
HMS Farnborough (Q.5) sank U-68 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. [6] Forced to return fire early, they managed to sink one U-boat and avoid two torpedo attacks. [7] Sanders was promoted to lieutenant commander, eventually commanding the topsail schooner HMS Prize in command of which he was awarded the Victoria Cross for an action on 30 April 1917 with U-93, which was severely damaged. Helgoland, while the ship sustained heavy shellfire, waited until the submarine was within 80 yards (73 m), 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 UB-48 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 Flower-class sloops 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 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. [8]
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. [9] 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. [10] 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. [11]
The Imperial German Navy commissioned six Q-boats during the Great War for the Baltic Sea into the Handelsschutzflottille. None [12] were successful in destroying enemy submarines. The German Q-ship Schiff K heavily damaged the Russian submarine Gepard of the Bars class 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 HMS Tarpon. The German 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 USS 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. [13]
Nine Q-ships were commissioned by the Royal Navy in September and October 1939 for work in the North Atlantic: [14]
Prunella and Edgehill were torpedoed and sunk on 21 and 29 June 1940 without even sighting a U-boat. The rest of the vessels were paid off in March 1941 without successfully accomplishing any mission. [15]
The last Royal Navy Q-ship, 2,456-ton HMS Fidelity, was converted in September, 1940, to carry a torpedo defense net, four 4-inch (100 mm) guns, four torpedo tubes, two OS2U Kingfisher floatplanes, and Motor Torpedo Boat 105. Fidelity sailed with a French crew, and was sunk by U-435 on 30 December 1942 during the battle for Convoy ON-154. [14]
By 12 January 1942, the British Admiralty's intelligence community had noted a "heavy concentration" of U-boats off the "North American seaboard from New York to Cape Race" and passed along this fact to the United States Navy. That day, U-123 under Kapitänleutnant Reinhard Hardegen, torpedoed and sank the British steamship Cyclops, inaugurating Paukenschlag (literally, "a strike on the kettledrum" and sometimes referred to in English as "Operation Drumbeat"). U-boat commanders found peacetime conditions prevailing along the coast: towns and cities were not blacked-out and navigational buoys remained lit; shipping followed normal routines and "carried the normal lights." Paukenschlag had caught the United States unprepared.
Losses mounted rapidly. On January 20, 1942, Commander-in-Chief, United States Fleet (Cominch) Earnest J. King, sent a coded dispatch to Commander, Eastern Sea Frontier (CESF), requesting immediate consideration of the manning and fitting-out of "Queen" ships to be operated as an antisubmarine measure. The result was "Project LQ."
Five vessels were acquired and converted secretly at the Portsmouth Naval Shipyard, Kittery, Maine: [16]
The careers of all five ships were almost entirely unsuccessful and very short, with USS Atik sunk on its first patrol with all hands on 26 March 1942. [5] COMINCH strongly criticized the program and all Q-ships patrols ended in 1943. [10]
American Q-ships also operated in the Pacific Ocean. One was USS Anacapa (AG-49) formerly the lumber transport Coos Bay which was converted to Q-ship duty as project "Love William". Anacapa was not successful in engaging any enemy submarines, although she is believed to have damaged two friendly subs with depth charges when they were improperly operating in her vicinity. Anacapa was also withdrawn from Q-ship duty in 1943 and served out the remainder of World War II as an armed transport in the South Pacific and Aleutian Islands.
The US Navy did not use a consistent hull classification symbol for its Q-ships (AG, AK, AO, IX and PYc were all used). This and the unprecedented use of duplicate hull numbers for Asterion and Atik reflect the great secrecy attached to these ships.
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. [17]
A surviving example of the Q-ships is HMS Saxifrage, a Flower-class sloop of the Anchusa group completed in 1918. She was renamed HMS President 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.
As with other naval concepts, the idea of a Q-ship has also been applied to space vessels in fictional works:
Q-ships feature prominently in David Weber's Honor Harrington series of books. Harrington destroys a Q-ship in the first novel, On Basilisk Station , and commands a squadron of Q-ships in the sixth novel, Honor Among Enemies . In the tenth book in the series, War of Honor , Thomas Bachfisch commands a pair of privately owned Q-ships. [18]
In the Jan/Feb 2020 issue of Analog Science Fiction and Fact, Joel Richards has a short story titled "Q-ship Militant".
In DC Comics Star Spangled War Stories #71 (reprinted in DC Comics Weird War #1) the story "The End of the Sea Wolf!" is a postwar "flashback" story of a U-boat commander engaging a Q-ship in WWII.
An armed merchantman is a merchant ship equipped with guns, usually for defensive purposes, either by design or after the fact. In the days of sail, piracy and privateers, many merchantmen would be routinely armed, especially those engaging in long distance and high value trade. In more modern times, auxiliary cruisers were used offensively as merchant raiders to disrupt trade chiefly during both World War I and World War II, particularly by Germany.
German submarine U-47 was a Type VIIB U-boat of Nazi Germany's Kriegsmarine during World War II. She was laid down on 25 February 1937 at Friedrich Krupp Germaniawerft in Kiel as yard number 582 and went into service on 17 December 1938 under the command of Günther Prien.
The Type B1 submarine, also called I-15-class submarine was the first group of boats of the Type B cruiser submarines built for the Imperial Japanese Navy (IJN) during the 1940s. In total 20 were built, starting with I-15, which gave the series their alternative name.
SM U-151 or SM Unterseeboot 151 was a World War I U-boat of the Imperial German Navy, constructed by Reiherstieg Schiffswerfte & Maschinenfabrik at Hamburg and launched on 4 April 1917. From 1917 until the Armistice in November 1918 she was part of the U-Kreuzer Flotilla, and was responsible for 34 ships sunk (88,395 GRT) and 7 ships damaged.
German submarine U-124 was a Type IXB U-boat of Nazi Germany's Kriegsmarine during World War II. She operated in the Atlantic as part of the 2nd U-boat flotilla, both west of Scotland and east of the eastern US coast. She was also present off northern South America.
German submarine U-66 was a Type IXC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 20 March 1940 at the AG Weser yard at Bremen, launched on 10 October and commissioned on 2 January 1941 under the command of Kapitänleutnant Richard Zapp as part of the 2nd U-boat Flotilla.
German submarine U-123 was a Type IXB U-boat of Nazi Germany's Kriegsmarine that operated during World War II. After that conflict, she became the French submarine Blaison (Q165) until she was decommissioned on 18 August 1959.
German submarine U-515 was a Type IXC U-boat of Nazi Germany's Kriegsmarine built for service during World War II. She was commissioned on 21 February 1942 and sunk on 9 April 1944. U-515 completed seven operational patrols and sank 23 ships, badly damaged two ships which later sank, and damaged two additional ships.
HMS Marigold was a Flower-class corvette of the Royal Navy. She was launched on 4 September 1940 and was sunk by an Italian air-dropped torpedo on 9 December 1942.
A deck gun is a type of naval artillery mounted on the deck of a submarine. Most submarine deck guns were open, with or without a shield; however, a few larger submarines placed these guns in a turret.
SM U-70 was a Type U 66 submarine or U-boat for the German Imperial Navy during World War I. She had been laid down in February 1914 as U-11 the final boat of the U-7 class for the Austro-Hungarian Navy but was sold to Germany, along with the others in her class, in November 1914.
SM UC-63 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy during World War I. The U-boat was ordered on 12 January 1916, laid down on 3 April 1916, and was launched on 6 January 1917. She was commissioned into the German Imperial Navy on 30 January 1917 as SM UC-63. In nine patrols UC-63 was credited with sinking 36 ships, either by torpedo or by mines laid. UC-63 was torpedoed and sunk by HMS E52 off Goodwin Sands on 1 November 1917; only one crewman survived the sinking.
His Majesty's or HM Armed Smack Inverlyon was a fishing smack that was converted to a Q-ship during the First World War. Q-ships served as decoys to lure German submarines near enough so that concealed weapons could be brought to bear and sink the submarines. On 15 August 1915, Inverlyon succeeded in luring German submarine UB-4 within range and sinking her with nine shots from her gun. The Royal Navy Gunner in command of the vessel, Ernest Martin Jehan, received the Distinguished Service Cross and members of Inverlyon's crew shared the bounty offered for German submarines. After Inverlyon's Q-ship career ended, she returned to fishing, but was sunk by U-55 on 1 February 1917.
The U-boat campaign from 1914 to 1918 was the World War I naval campaign fought by German U-boats against the trade routes of the Allies. It took place largely in the seas around the British Isles and in the Mediterranean. The German Empire relied on imports for food and domestic food production and the United Kingdom relied heavily on imports to feed its population, and both required raw materials to supply their war industry; the powers aimed, therefore, to blockade one another. The British had the Royal Navy which was superior in numbers and could operate on most of the world's oceans because of the British Empire, whereas the Imperial German Navy surface fleet was mainly restricted to the German Bight, and used commerce raiders and submarine warfare to operate elsewhere.
Ernest Martin Jehan DSC was a British officer in the Royal Navy during the First World War. Jehan is best known for the sinking of a German U-boat by him and his crew aboard the smack Inverlyon. He began the war as a warrant officer and was decorated and commissioned after sinking SM UB-4 (2).
The Atlantic U-boat campaign of World War I was the prolonged naval conflict between German submarines and the Allied navies in Atlantic waters—the seas around the British Isles, the North Sea and the coast of France.
SM U-21 was a U-boat built for the Imperial German Navy shortly before World War I. The third of four Type U-19-class submarines, these were the first U-boats in German service to be equipped with diesel engines. U-21 was built between 1911 and October 1913 at the Kaiserliche Werft in Danzig. She was armed with four torpedo tubes and a single deck gun; a second gun was added during her career.
The Torpedo Alley, or Torpedo Junction, off North Carolina, is one of the graveyards of the Atlantic Ocean, named for the high number of attacks on Allied shipping by German U-boats in World War II. Almost 400 ships were sunk, mostly during the Second Happy Time in 1942, and over 5,000 people were killed, many of whom were civilians and merchant sailors. Torpedo Alley encompassed the area surrounding the Outer Banks, including Cape Lookout and Cape Hatteras.
Captain Cedric Naylor was a Royal Navy officer of the First and Second World Wars. Naylor was a merchant seaman before joining the Royal Naval Reserve on the outbreak of the First World War. In November 1915 he was posted as first lieutenant to HMS Penshurst, a Q-ship, a warship disguised as a merchant vessel intended to fool German U-boats into surfacing so they could be sunk. Naylor received the Distinguished Service Cross for his part in the sinking of SM UB-19 on 30 November 1916 and a bar for further operations in February and March 1917. Naylor was granted temporary command of Penshurst after its captain was incapacitated in June and the next month damaged a submarine, for which he was awarded the Distinguished Service Order. Further distinguished service in the following months saw him receive a bar to the medal and a transfer to the Royal Navy. Naylor was hunting for SM U-110 on Christmas Eve 1917 and Penshurst was struck by a torpedo fired by the submarine. Despite suffering heavy damage Naylor remained onboard with two gun crews, hoping the U-boat would surface to finish off the ship. When U-110 surfaced it was hit twice and damaged before Penshurst sank. Naylor survived and was awarded a second bar to his DSO. He commanded the sloop Polyanthus for the remainder of the war.
