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.
Globtik Tokyo
Globtik Tokyo was one of three oil tankers in its class. At the time her keel was laid in 1972 she was the largest supertanker in the world at 378.85 meters (1,242 feet) and 483,684 tonnes (dwt). She held that distinction until 1973 when her sister ship the "Globtik London" was launched. Identical in size the "London" was larger by 276 dead weight tonnes (dwt). Both ships had a hold capacity of 580 million liters (3.65 million US barrels).
