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.
Batillus-class supertanker
The "Batillus"-class supertankers was a class of supertanker ships built in France at the end of the 1970s. Four such ships were built between 1976 and 1979—serving until the final one was scrapped in 2003. They were built in the "Bassin C" dock of the Chantiers de l'Atlantique shipyards at Saint Nazaire, France. Measured by gross tonnage, these were, at the time, the largest ships of any type ever constructed.
