The U.S. Army vision for lethality science and technology investment is to enable overmatch in weapon systems for both offensive and defensive capabilities.
Army Chief of Staff Gen. Raymond Odierno said attaining overmatch is critical to the Army of 2025.
“The Army has global responsibilities that require large technological advantages to prevail decisively in combat – ‘technological overmatch,’” Odierno wrote for the Army’s official blog in 2012. “Just as airmen and sailors seek supremacy in the air and on the seas, Soldiers must dominate their enemies on land. Modernizing, especially as end strength is reduced, is the key to ensuring that the Army’s dominance continues.”
To achieve that supremacy, Army researchers aggressively pursue technological overmatch.
“In lethality, overmatch means we can defeat the threat to maintain an advantage,” said Keith Jadus, acting director of the lethality portfolio for the Office of the Deputy Assistant Secretary of the Army for Research and Technology. “That means we have an advantage in every sense of the word. Overmatch is much bigger than lethality. We need to be able to see farther, reach farther and to ensure that our forces are protected outside the range and influence of the enemy.”
Jadus said the goal of the lethality portfolio is to create an unfair fight.
“Part of my strategy in lethality S&T is that we maintain overmatch,” he said. “It’s absolutely true that lethality is part of creating an unfair fight, but we should never forget all the other pieces of that fight.”
As researchers seek new offensive capabilities for long-range fires and small arms, they are also considering the Army’s requirements for defensive postures such as air and missile defense.
“For air defense and missile defense, we’re looking at kinetic weapons systems, such as missiles and gun systems, and non-kinetic weapons, such as high-energy lasers. These systems will be used to defeat rockets, artillery, mortars, unmanned aircraft and cruise missiles and also high-energy lasers as a directed energy solution,” Jadus said.
“Lethality is more than just offensive lethality,” Jadus said. “It is the ability to provide protection. Lethality is what protects our Soldiers. It is the capability to reach farther than our adversary and the ability for Soldiers to hold their ground, protect their ground and move forward.
The Lethality Portfolio represents S&T investments at the Armament Research Development and Engineering Center at Picatinny Arsenal, N.J.; the Aviation and Missile Research Development and Engineering Center and Space and Missile Defense Command at Redstone Arsenal, Ala.; and the Army Research Laboratory at Aberdeen, Proving Ground, Md.
Jadus manages an annual investment portfolio of nearly $250 million with wide-reaching implications for the Army of the future.
“The Army has to deliver affordable weapons systems because of the large number of systems it buys,” Jadus said. “With the budget environment we are in, we have to focus our technologies on how we can bring additional capability while maintaining affordability.”
Army leadership wants to increase the range of its weapons systems. Across the spectrum of weapons systems, the Army needs to be able to engage ground targets — even greater than 300 kilometers offensive range. Army S&T is working on long-range fires to extend the range of rockets to address this challenge, and significantly increase the range of cannon artillery. The Army is also working to extend the reach of Soldier weapons, including individual weapons, mortars and close combat missiles.
“We need to be able to maintain precision,” Jadus said. “We brought precision to our field artillery capability, and we’ve had precision in our rockets. We are trying to bring affordable precision to everything including small arms, 40mm grenades and mortars.”
The Army uses GPS to great effect; however, planners see a need to provide precision even if GPS is denied.
“If we utilize GPS for guidance on a missile or artillery shell, we have to make that sure if somebody shuts down our GPS, we can still deliver the precision we promised,” he said. “Technology investments today are focused on mitigating this risk.”
The Army also seeks a scalable range of effects, both lethal and non-lethal, Jadus said.
“Think of warhead effects that are able to be increased or decreased,” he said. “We envision the capability to decrease lethality to reduce collateral damage, or increase lethality tailored to the targets. Traditionally we have focused a lot of our warhead technology on hard vehicle targets, but we need to be able to defeat a range of targets such as light vehicles, buildings and bunkers. We also need non-lethal solutions for our maneuver forces to operate in areas with non-combatants”
Researchers and engineers have been manipulating an energy density curve for energetic materials for decades.
“Advancements have been incremental — 5 or 10 percent here and there for a long time,” Jadus said. “But Army researchers are rethinking all the physics. They’re going to the molecular level and discovering how we can put a lot of energy in a molecule and then find out how we can release that energy and look at something that would give us an increase of an order of magnitude or more in our energetic density.”
What this can do for the Army is huge, he said. With new material science advances, researchers foresee a 40mm grenade that a Soldier fires from a rifle to deliver dramatic effects.
“You can really change the dynamic of what that Soldier is able to do,” Jadus said. “It may mean a 40mm grenade with 155mm artillery effects. We may not get there, but it is certainly where this can take us. It can also radically increase the range of our weapons”
It’s all in the name, he said. Disruptive goes beyond leap-ahead technologies.
“When we start getting these capabilities out there I think it’s going to be disruptive,” Jadus said. “We’re going to have to look at how we engage in warfare. Advanced capability such as this warrants a holistic review of Army tactics, techniques and procedures. A battlefield where an individual Soldier possesses artillery lethality within a grenade-sized munition is a much different battlefield.”
Researchers are also looking to one solution to counter the threat of rockets, artillery, mortars and missiles, and unmanned aerial vehicles with directed energy.
“Directed energy applications are considered game-changing technologies by the Army,” said Richard De Fatta, director of the Emerging Technology Directorate within the Technical Center of the U.S. Army Space and Missile Defense Command and Army Forces Strategic Command. “When fielded, they will provide cost and operationally effective alternatives to conventional missiles, guns, and similar systems. A directed energy ‘bullet’ is generated almost entirely by electrical energy and does not require resupply except fuel to generate electricity.”
With high-energy lasers, Jadus said there is still a lot to work out.
“We recently had some impressive demonstrations using a commercial laser and supporting beam control, power, and thermal subsystems all integrated onto a mobile military truck, yet we still need to further mature the technology,” he said. “Our laser programs are achieving promising results in the laboratory, and we are developing support subsystems to enable long run-times at these laser’s higher power levels.”
The Army is also looking at high-powered microwave and high-powered radio frequency technology to defeat electronics and other capabilities and help to disrupt other targets, such as the improvised explosive device threat.
“We’re looking at this as a non-lethal weapon,” Jadus said. “We can use a high-powered microwave to put energy on a person and force them to move out of the way. I’ve talked to Soldiers who have been demonstration subjects on this project. When subjected to the high-power energy beam, the demonstration subjects become so uncomfortable that they move away from the source. We are leveraging work done by the Joint Non-Lethal Weapons Directorate led by the Marine Corps and the Air Force on this technology.”
Jadus said it will be interesting to see how the Army uses this capability.
“Some people call it a front bumper for our combat vehicle fleet. We can mount this on the front of a vehicle, so that if a crowd starts to come toward the vehicle, we can politely move them out of the way by putting a little bit of energy on them,” he said. “It also helps us determine intent. If somebody is not pointing a gun at us, we can use a non-lethal device to disperse them. If they respond aggressively we can escalate to a lethal interaction, but it gives us the option not to have to.”
“I think a lot of technology that is advancing in the commercial world is of a lot of value to us,” Jadus said. “We spend a lot of time looking at those technologies and then figuring out if we can use them in the military environment.”
A challenge to developers is the gun-launch environment. As a gun-launched projectile exits the tube it may experience 20,000 or 30,000 Gs of force.
“There are not a lot of systems that encounter that shock,” Jadus said. “We’re talking tens of thousands of G forces exerted on electronics chips. We have to figure out how to make sure our chips are sufficiently hardened to weather that environment and remain viable. Those chips are essential to the accuracy of those systems because we
have a very low tolerance for an error in the guidance system in a weapon. Honestly the difference is life and death.”
Because the stakes are high, S&T investments are critical, Jadus said.
“We have the unique opportunity to explore and look at how we solve problems a little bit differently and with more innovation,” he said. “We can shape the future. We can go try things. I think the environment we’re in now is one of collaboration. We have frequent dialogs with our user representatives and our program executive office partners. We also work with them to develop long-range plans.”
The Army also actively collaborates with industry and foreign partners to better understand what they have available.
“I believe in order for Army S&T to be truly innovative and deliver revolutionary capability to our warfighters, we need to expand our search beyond our traditional labs,” Jadus said. “Taking the best industry, academia and our research partners have to offer, only then can we successfully increase our overmatch.”
In recent years, the Army completed an internal process review on how it does long-range investment planning.
“This has been a windfall for S&T because now we know where the Army wants to go in the future,” Jadus said. “Now we have a really good process to vet the future years’ requirements and what associated technologies we need to develop. Does the Army want a new tank gun in the future or a new artillery system? The good news is we develop broad-based technology that applies to more than just one system. S&T is critical for the future as it informs the Army of the possible.”
Jadus said there are many good S&T programs ongoing that will pay future dividends in terms of Army capabilities.
“If we don’t prove it in S&T, and we don’t deliver an affordable solution, when the program of record comes along it costs more to learn those lessons there,” he said. “We play a critical role because we’re helping to shape the path to the future. I think we’re in a position to make a big difference. We have the talent to pull this off and that’s exciting. I’m extremely optimistic. I think we’re going to see a lot of new capabilities coming down the road. We are pushing forward to modernize the force. We have put an unthinkable capability in weapon systems that a Soldier can take onto the battlefield, but we still have a lot of work to do. We’ve gotten more precision and range, but everything we do is challenged. For every advancement through S&T lethality, an adversary is working on a way to defeat or marginalize it. That is why S&T in this area is really a big priority.”
