The US Army is likely to purchase Israel's Iron Dome anti-rocket system for deployment outside forward bases in Iraq and Afghanistan against attacks from 107mm Katyushas rockets.
The Jerusalem Post has reported that an official request from the US Department of Defence may be issued for technical specifications regarding the system ahead of a potential purchase.
The Iron Dome batteries consist of a mobile air defence system with a radar-guided interceptor missile, launched from a truck-sized firing platform.
The radar-guided interceptor missile is designed to destroy mid-air rockets and mortar bombs that have ranges of 5-70km.
Israel already has two operational batteries deployed outside the southern city of Beersheva, which have successfully intercepted rockets fired from the Gaza Strip.
South Korea has also expressed an interest in the system to defend against North Korean rocket attacks.
