Depends on what tank you are referring to. The M1A2 Abrams tank has 120 mm (4.72 inches) of armour.
It is among the most advanced in production, though it's not the only such tank in existence.
The biggest tank in the world would probably be the US M1A2 Abrams main battle tank.
The M1A2 costs $6.21 million per, although there have since been upgrade programmes which have likely made the tank more expensive.
In February 2001, GDLS were contracted to supply 240 M1A2 tanks with a system enhancement package (SEP) by 2004. The M1A2 SEP contains an embedded version of the US Army's Force XXI command and control architecture; new Raytheon commander's independent thermal viewer (CITV) with second-generation thermal imager; commander's display for digital colour terrain maps; DRS Techologies second-generation GEN II TIS thermal imaging gunner's sight with increased range; driver's integrated display and thermal management system. further details can be found at www.army-technology.com/projects/abrams
The cost is around 4 million.
