Panzer VIII Maus
Panzerkampfwagen VIII Maus ("Mouse") was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armoured fighting vehicle ever built. Five were ordered, but only two hulls and one turret were completed before the testing grounds were captured by advancing Soviet military forces.
History of the oil tanker
"Seawise Giant" was renamed "Happy Giant" in 1989, "Jahre Viking" in 1991. From 1979 to 2004 she was owned by Loki Stream, at which point she was bought by First Olsen Tankers, renamed "Knock Nevis" and converted into a permanently moored storage tanker. The Batillus class supertankers are the biggest ships ever constructed by gross tonnage.
