The Navy Times reports that the U.S. Army has recently fulfilled four contracts involving the development of next-generation jamming electronic warfare systems. The new system is touted to replace the ALQ-99, a new military jamming system that acts like a shield to protect U.S. aircraft from enemy missiles. The U.S. Navy is currently planning to invest $4 billion in the development of this new generation of military signal jammer.
The ALQ-99 jamming system has been used by the U.S. Army for a range of missions, from the retired EF-111 Raven to the Navy and Marine Corps EA-6B Prowler and the Growler electronic warfare jet known as the EA-18G.
The new version of the military jammer is highly efficient at interception; it processes the signal automatically, and even jams the received signal of said radio frequency, while it is able to detect and locate the source of these signals.

Electronic warfare aircraft find ample use in today's combat operations. So, with the number of roadside bombs rising dramatically in the Taliban and Afghanistan, the U.S. military is now rushing to get the latest upgrade in jamming weapons, not just relying on radio and cell phone communications.

The best solution to this problem is to develop a better jamming system that is more efficient, stealthy, has a longer range, and can even hit targets protected by modern defense networks; the Pentagon, which needs to work now, is considering this .

Not only that, but the Air Force is also working on a new system to locate military GPS jammer from enemy satellites.
