- Was postponed, then never carried out.
- The plan was created after the falling of France because Great Britain was the only European Power left.

-September 3,1939–May 8,1945
-Germany against Allies
-Battle for Great Britain’s very survival -Also known as Q-boats, decoy vessels, special service ships, or mystery ships.
-They 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 (RN) during the First World War.
-Both the RN and the United States Navy used Q-ships during the Second World War (1939–1945), as a countermeasure against German U-boats and Japanese submarines. Q-ship

- First appeared in World War Two
- They were very seaworthy and maneuverable, but living conditions for ocean voyages were appalling.
- Because of this the corvette was superseded in the Royal Navy as the escort ship of choice by the frigate, which was larger, faster, better armed and had two shafts Many countries today operate corvettes; some include Argentina, Brazil, Bulgaria, China, Denmark, Germany, Egypt, India, Indonesia, Iran, Israel, Italy, Pakistan, Philippines, Poland, Portugal, Romania, Russia, South Korea, Sweden and Turkey. Countries that border smaller seas, such as the Baltic Sea or the Persian Gulf, are more likely to build the smaller and more maneuverable corvettes, with Russia operating the most Corvettes in the world Fall of the U-Boats
