Q-ships or Q-boats were disguised merchant vessels that carried cannons, depth charges and antisubmarine equipment. They were used as a bait to attract and then sink German U-boats during World War I primarily by Britain and, later, during World War II predominantly by the United States. In the United Kingdom the vessels chosen for this service were code-named Q-ships by the Admiralty, but they were also known as Decoy Vessels, Special Service Ships or Mystery Ships. The Germans had similar ships called merchant raiders.
