ACC: Why Replace One Vulnerable J-Stars With Another?
The U.S. Air Force’s $7 billion decision whether to replace the E-8C J-Stars with another radar-carrying aircraft or take another path comes down to survivability, and how long it might take to field something better.
If facing a well-equipped adversary, Air Combat Command believes the 707-based E-8C Joint Surveillance Target Attack Radar System (J-Stars) would probably be shot out of the sky before it could get close enough to a target to be useful. Buying another vulnerable, commercial-derivative aircraft to replace the 16-strong E-8C fleet won’t solve that fundamental problem.
“We don’t believe the J-Stars Recapitalization will give us the capability we need in contested or highly contested environments,” says ACC chief Gen. Mike Holmes, speaking at a Mitchell Institute for Aerospace Studies event in Washington on Nov. 20. “The decision as we go forward is whether we need to invest in one for uncontested environments while we bridge to a global capability that could do that on any battlefield, or not.”
The service issued a request for proposals for an E-8C replacement in December 2016, a deal potentially worth up to $6.9 billion for the development and production of 17 aircraft. Boeing responded with a proposal based on its airliner. Northrop is offering a Gulfstream G550-based J-Stars, while Lockheed has teamed with to offer the Global 6000. One of these aircraft would replace the E-8C, which is equipped with a 24-ft. APY-7 passive array radar.
The E-8C was conceived in the 1980s as a way of detecting Soviet troops mobilizing for war in Eastern Europe. These days, the aircraft are used mostly for relaying battlefield communications and detecting small, moving targets, like vehicles and dismounted insurgents.
Although ground-moving target indication is one of J-Stars’ core competencies, Holmes notes that several other platforms introduced since the E-8C have this same capability or better. Those include the Air Force’s Northrop RQ-4B Block 40 , the U.S. Navy’s and the U.S. Army’s Beechcraft King Air 350 and Bombardier Dash 8-based Northrop ZPY-5 Vehicle And Dismount Exploitation Radar, or Vader. Meanwhile, the Air Force is funding the development of two competing active, electronically scanned array radars by Northrop and for J-Stars, which will provide essentially the same capability, albeit specialized for overland surveillance.
Holmes says no decision has been made yet about proceeding with, or canceling, the J-Stars competition. He would prefer that the Air Force concentrate its scarce time and resources on a survivable platform that can operate in a tactical, contested environment, something the E-8C, Global Hawk and Poseidon cannot do today. But he notes that this will take many years to develop, and a simpler E-8C replacement program might be needed in the interim. “Do we need to invest in one more recapitalization before we move to the future, or are there other ways we can bridge that gap between now and the future?” he asks. “No decision made yet.”
Despite the uncertainty, Congress has approved more than $400 million in fiscal 2018 to support the J-Stars Recap program. The E-8C, based in Georgia, also has powerful backers in Congress who have been pressing the Air Force to stay the current course.
