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.
Valemax
The "Valemax" vessels are also the second largest ships in service by deadweight tonnage, second only to the TI-class supertankers that have a deadweight tonnage of over 440,000 tons. They are still far from the largest ship ever constructed — "Seawise Giant" (labeled as the "Knock Nevis" in the adjacent image), built in 1979 and broken up in 2009, was long and had a deadweight tonnage of 564,650 tons — and also considerably longer than the longest ship currently in service, the container ship "Barzan".
