It just keeps getting better.
The U.S. Army is on an intensive quest for an array of new technologies with which to design and build new armored fighting vehicles, particularly a replacement for the long-serving Bradley. However much it might yearn for a new tank, the Army lacks the critical technologies that would justify the time and expense pursuing such an objective. Moreover, it doesn't need to make the effort. The Army's current main battle tank, the Abrams, is the tank of the future.
The Army is just beginning to receive the first of the latest Abrams upgrade, the System Enhancement Package Version 3 (SEPv3), with additional upgrades in development. Instead of searching for the elusive Holy Grail of ultralight armor or laser weapons, technologies that would justify building a brand new tank, the Army would be best served by aggressively pursuing a major redesign and improvement program for the Abrams, an M1A3.
The leadership of the U.S. Army is taken with the idea of transforming how and with what the Army fights. They particularly want new armored fighting vehicles. And not just another family of metal boxes with a turret and cannon. Technology enthusiasts, including many in the Army's new Futures Command, wax eloquently about the potential for hover tanks that shoot laser beams and are autonomously guided by artificial intelligence housed in quantum computers.
