DARPA aims to revolutionise tank design
The U.S. military is researching possible designs for a new generation of stealthier, faster, more mobile tanks.
For the past 100 years of mechanised warfare, protection for ground-based armoured fighting vehicles and their occupants has boiled down almost exclusively to a simple equation: more armour equals more protection. Weapons’ ability to penetrate armour, however, has advanced faster than armour’s ability to withstand penetration. As a result, achieving even incremental improvements in crew survivability has required significant increases in vehicle mass and cost.
The trend of increasingly heavy, less mobile and more expensive combat platforms has limited Soldiers’ and Marines’ ability to rapidly deploy and manoeuvre in theatre and accomplish missions in varied and evolving threat environments. Moreover, larger vehicles are limited to roads, as well as requiring more logistical support and are more expensive to design, develop, field and replace. The U.S. military has now reached a point where – considering tactical mobility, strategic mobility, survivability and cost – innovative and disruptive solutions are necessary for a new generation of armoured fighting vehicles.
The Defense Advanced Research Projects Agency (DARPA) has created the Ground X-Vehicle Technology (GXV-T) program to overcome these challenges. GXV-T seeks to investigate revolutionary ground-vehicle technologies that would simultaneously improve the mobility and survivability of vehicles through means other than adding more armour – i.e. avoiding detection, engagement and hits by adversaries. This improved stealth and mobility would enable future U.S. ground forces to more efficiently and cost-effectively tackle the varied and unpredictable combat situations of the 21st century.
“GXV-T’s goal is not just to improve or replace one particular vehicle – it’s about breaking the ‘more armour’ paradigm and revolutionising protection for all armoured fighting vehicles,” says Kevin Massey, DARPA program manager. “Inspired by how X-plane programs have improved aircraft capabilities over the past 60 years, we plan to pursue groundbreaking fundamental research and development to help make future armoured fighting vehicles significantly more mobile, effective, safe and affordable.”
Technical goals include the following improvements relative to today’s armoured fighting vehicles:
DARPA says these four technical areas are examples of where advanced technologies could be developed that would meet the program’s objectives:
DARPA aims to develop GXV-T technologies over a period of 24 months, from 2015 to 2017.
