EspañolARMED MERCHANTMEN
'Armed Merchantmen' has come to mean merchant ships taken over by their nation's navies, equipped with guns, and then used for military purposes. However in the days of sail, piracy and privateers many merchantmen, especially those engaging in long distance and high value trade would be routinely armed. The most famous of this ilk being the East Indiamen which were known to be able to defeat regular warships in battle.
These were used in both World Wars by both Germany and the United Kingdom. Whilst the British used armed passenger liners for protecting their shipping, the German approach was to use them to attack enemy shipping.
The Armed Merchant Cruisers (AMC) of the British Navy were employed for convoy protection against enemy warships. They were found to be of limited usefulness because they lacked the armour and ranging systems of a warship, and many were converted into troopships.
One famous AMC of World War I was the British RMS ''Carmania'' which, after a heated battle which caused heavy damage on both sides, succeeding in sinking the German auxiliary cruiser ''Cap Trafalgar'' near the Brazilian island of Trinidade in 1914.[1]
The German practice was to arm merchantmen with hidden weapons and use them as commerce raiders. An auxiliary cruiser - ''Hilfskreuzer'' or ''Handels-Stör-Kreuzer'' (HSK) - usually approached her target under a false flag with guns concealed, and sometimes with her appearance altered with fake funnels and masts and often a fake paint job. The victim was thus engaged at point-blank range and had no chance to escape. In the First World War, the Imperial German Navy initially used fast passenger ships (such as past holders of the Blue Riband for fastest North Atlantic crossings), but they made obvious and easy targets because of their very familiar silhouettes. The Germans therefore soon moved on to using captured and refitted Allied vessels, but principally only modified transport ships. These were slower but less recognizable. In both world wars, these ships were found to be vulnerable to attack, and were withdrawn before the war ended. Many were sunk after being caught by regular warships - an unequal battle since auxiliary cruisers had poor fire control and no armor. There were, however, a few success stories. The ''Kaiser Wilhelm der Große'' was a former passenger liner that sank two freighters in 1914 before being caught by HMS ''Highflyer''. Her sister ship, the ''Kronprinz Wilhelm'', had a legendary journey, sinking or capturing a total of 15 ships in 1914 and 1915, before finally running out of supplies and having to put into port in Virginia, where she was interned by the Americans and eventually converted into a US Navy troop transport (as the renamed USS ''Von Steuben''). The most famous German commerce raider of WWI probably was SMS ''Seeadler'', a sailing ship commanded by the legendary Count Luckner.
The concept was revived in the Second World War. In one incident, the German ''Kormoran'' (ex-merchantman ''Steiermark'') managed to surprise and sink the Australian light cruiser HMAS ''Sydney'', which approached too close, though the ''Kormoran'' herself was also sunk in the engagement. This was the only occasion in history when an armed merchantman managed to sink a modern warship; in most cases auxiliary cruiser raiders tried to avoid detection.
In World War II, the German Navy operated ten very successful auxiliary cruisers which ranged in tonnage from 3,860 - 9,400; typically these vessels were equipped with:
★ Floatplanes
★ 15 cm guns
★ Smaller armaments (typically hidden away behind specially designed and hinged bulwarks, or beneath fake deckhouses and/or skylights)
★ Torpedoes
★ Mines
To preserve their cover, these ships flew the flags of neutral or occasionally Allied nations. They were re-fuelled and provisioned by special supply ships and from Japanese island bases, or they simply reprovisioned themselves from prizes they had taken.
To counter the effectiveness of these disguises the Allies introduced the check-mate system in 1942 to identify individual ships on a one-by-one basis with the Admiralty in London.
During World War II German auxiliary cruisers are believed to have either sunk or captured some 800,000 tons of Allied shipping.
Compare to the Q-ship, which was a disguised merchantman for anti-submarine operations.
The CAM Ship (from catapult armed merchantman) was a British merchantman fitted with a catapult that could launch, but not recover, a single fighter aircraft.
The Merchant aircraft carrier or 'MAC' was a British or Dutch cargo ship with a flight deck that could carry a small number of aircraft.
CAM and MAC ships remained as civilian ships operated by civilian crews, with Fleet Air Arm or Royal Netherlands Navy "air parties".

Auxiliary cruiser
The German practice was to arm merchantmen with hidden weapons and use them as commerce raiders. An auxiliary cruiser - ''Hilfskreuzer'' or ''Handels-Stör-Kreuzer'' (HSK) - usually approached her target under a false flag with guns concealed, and sometimes with her appearance altered with fake funnels and masts and often a fake paint job. The victim was thus engaged at point-blank range and had no chance to escape. In the First World War, the Imperial German Navy initially used fast passenger ships (such as past holders of the Blue Riband for fastest North Atlantic crossings), but they made obvious and easy targets because of their very familiar silhouettes. The Germans therefore soon moved on to using captured and refitted Allied vessels, but principally only modified transport ships. These were slower but less recognizable. In both world wars, these ships were found to be vulnerable to attack, and were withdrawn before the war ended. Many were sunk after being caught by regular warships - an unequal battle since auxiliary cruisers had poor fire control and no armor. There were, however, a few success stories. The ''Kaiser Wilhelm der Große'' was a former passenger liner that sank two freighters in 1914 before being caught by HMS ''Highflyer''.
