A next-generation guided ammunition system for intercepting enemy fire that Lockheed Martin is developing for the Army has hit its targets in an initial series of tests by the company. Lockheed’s Extended Area Protection and Survivability (EAPS) hit-to-kill interceptor is a ground-mounted gun system meant to stop and destroy enemy rockets, artillery shells, and mortars by tracking fired targets before they reach their intended mark.
The weapon -- which has a 360-degree range of protection -- represents a new direction in anti-artillery fire aimed at keeping Army ground forces safe from enemy weapons after they are launched, a capability that is currently limited, according to the Army.
Bill Nourse, manager of the Extended Area Protection and Survivability Program, explains the concept behind an interceptor missile to John McHugh, secretary of the Army; John Rogers, civilian aide to the secretary of the Army; Gen. Ann Dunwoody, commander of Army Materiel Command; and Steve Cornelius, director for Missile Development, AMRDEC.

During recent tests, the EAPS system’s fire control sensors were able to track targets for a full target engagement sequence, from launch of an enemy projectile to a simulated launch of an EAPS missile to interception of the enemy weapon, according to Lockheed.
The company collaborated with the US Army Research Development & Engineering Command/Aviation Missile Research Development & Engineering Center (AMRDEC) to conduct the tests, which demonstrated the system’s ability to track and intercept an enemy weapon from the time it’s been launched during its entire trajectory. "The data collected is being analyzed so that the program learns as much as possible and we can incorporate improvements and changes where needed," said Loretta Painter, AMRDEC EAPS program director, in a press statement.
Lockheed has designed the EAPS system to be small and agile. Its interceptors, or bullets, weigh about 3kg and are less than 50mm in diameter and less than 1m long. In addition to the interceptor, the system also features a radar-sensing system for tracking its targets. The system was also built to be modular, supporting existing and multiple launchers and fire control sensors that the Army already has been using.
Affordability is also a key design goal for the system, which Lockheed said will meet the AMRDEC's goals for average unit production costs at specified quantities. The initial series of EAPS tests is a precursor to several more Integrated Demonstration flight tests of the system Lockheed has scheduled, including a non-targeted test flight later this month and several guided flights against tactical targets later in the summer.
Wiliam K; That is a very good point. Optimization of that feature might even be a better route to go. If one shot from a position was enough to have that position identified and destroyed by return fire (in less than a minute ?), who would dare to shoot first ?
One interesting unmentioned fact is that if the system can track incoming well enough to hit them, it can also track well enough to locate the launch site and target it with "suitable response". The result is that an attempt to overwload the intercept system would certainly provide lots of return fire targeting information. One other detail is that the same intercepting system could also target incoming with directed energy weapons, which have a very good "hit" score Also, directed energy travels very fast.
I hate to be skeptical but hitting a missile with a missile is a daunting task----seeing is believing.I worked in ballistic systems during my years in the Air Force and deployment speeds lead me to believe the reliability relative to "hits" would be considerably lower than would be tolerated.Basically, show me a system and give me the hard data on the number of strikes.
What they HAVE in common is exhibited precisely in the movie "BRAZIL". Any one who reads Design News should be required to see the movie. I'm betting that most of the readers of this column don't know about "Brazil" the world's most accurate (and entertaining) predicition of the future.
It should be required viewing for all high school and college students.
Intercept by tracking works best if the launch takes place from the target area. If these rockets are fired from a "safe" area, they will lose effectiveness. This means intercept can easily change to pursuit and that's whole new ballgame - and may add to enemy fire.
Of course, launching from the target area will surely increase the incentive to make a hit.
Not all applications require no collateral damage. It can be handled operationally by implementing in an AO with clear fire zones. As I staed in a previous post, CM is very unlikely for this class of target.
More than likely adversaries would try to overwhelm the system to regain effectiveness. This would require more of them to break cover and become targets themselves, which incidentally, is the biggest problem we have in low intensity conflict; identifying bad guys well enough to fit the ROEs. When they finally meet criteria under the ROEs, they don't last very long.
Closing speed in this application is an order of magnitude less than BMD (the current progeny of SDI), and BMD has proven fairly successful.
Current systems like the CIWS can detect, track, and intercept artillery rounds with unguided 20mm DU or tungsten rounds.Although it shoots 3000 rnds/min to accomplish the task, this new system uses a guided interceptor to reduce the amount of ammo expended for defense.
Lock Mart has had some issues in other areas in the past, but also a long line of successes in the missile realm (PAC-3, THAAD, ATACMS, GMLRS, Hellfire...).Although it is ballistically launched, a guided weapon is a guided weapon.
Yes, if you read the article it has only been successful as a simulation. Until real-life targets and real-life countermeasures work it is still pie-in-the-sky. And collateral damage has to be zero = no non-targets destroyed. It's too early for the posted enthusiasm.
Artillery ammunition isn't currently that sophisticated.It is unlikely that an adversary would waste time trying on-projectile counter measures as any additional payload would require a reduction in warhead size. Ultimately an arms race in this niche would result in expensive artillery rounds that were less effective than they were originally - a win-win for us!
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.
