General

In a displacement 500-3700 tons network Leger have a seagoing endurance 3-15 days, and may thus in at a rate of 10 to 15 knots 2,000 and 3,500 nautical miles interlocutory cruising cover. The crew of European net layers consists of 30 to 180 men; In the Asian region ( Korea , Japan , Taiwan ) there are also smaller netsetters with a crew of up to 20 men. The armament of net laymen was and is very different, which is also due to the fact that conversions of civil or military sea vehicles were often used for this purpose. Today's net layers usually have an armament of up to eight anti-aircraft guns of 2 to 4 cm caliber.

The first net layer was the Guardian (3,665 tons), launched in Great Britain in 1932.

Different navies

The German Navy had a total of 18 net layers in service during World War II ; there were also three net lighters and 57 net tenders.

In the Second World War, the American Navy had a total of 77 net layers in service, mainly in the Pacific, where they laid steel nets around individual ships or entire anchorages to protect against torpedoes and submarines. The ships were marked with the hull identification "YN" ("Yard Net Tender") or "AN" ("Auxiliary Net Layer"). The first 32, all launched in 1940, were made of steel, the next 30 were made of wood because of the war-related steel shortage, and the last 15, which were laid down in 1944 and 1945, were again made of steel.
