F-class escort ship

The F-class escort ships were a class of fleet escorts (Flottenbegleiter) used by the Kriegsmarine during the Second World War. Ten ships were built in total, of a type roughly comparable to British frigates or American destroyer escorts. They were the only such type of ship built by the Kriegsmarine. The ten ships were not given names, but were designated F1 through F10.

Construction

The ships were built by Germaniawerft (F 1 – F 6), Kiel, Blohm & Voss (F 7, F 8) and Wilhelmshaven dockyard (F 9, F 10). They entered service between 1936 and 1939. The ships were originally conceived as fast fleet or convoy escort ships that could also perform anti-submarine and minesweeping work. They were also used as a testbed class for a new high-pressure steam power plant intended for use in future destroyers.

As a class, they were overloaded and over-engined, which contributed to severe hull stress and very poor sea-keeping characteristics; these flaws were partially remedied by extensive rebuilds between 1938 and 1940. The power plants likewise proved to be prone to frequent breakdowns, and most of the ships were removed from operational service during the later years of the war after machinery failures meant the ships spent more time in repair than in use.

Use and administration

With the exception of fleet service and convoy duties between 1939 and 1941, they spent most of the war in use as tenders or U-boat training ships. Between 1943 and 1945, the escort ships were grouped into five escort flotillas augmented by converted civilian craft as well as torpedo boats of the Torpedoboot Ausland program.

One ship, F 9, was sunk in December 1939 after being torpedoed by HMS Ursula. F 5 was damaged by a mine in the Baltic Sea and sank under tow 29 January 1945. F 3 was sunk by British aircraft 3 May 1945 and F 6 was sunk by US aircraft 30 March 1945. The others survived the war and were scrapped or sunk as target ships.
