ON TARGET
Sometimes what’s needed is a really big bomb.
what to do, and make course corrections according to the changing position of the enemy or intelligence. Tese are just some of the difficult scenarios that ARL grapples with. Another issue is adapting to a common operating picture.
HARD QUESTIONS Te U.S.
intends to defeat near-peer
adversaries who have had time to estab- lish themselves in a foreign city. Scientists prepare by taking a hard look at how to deliver firepower to difficult targets in places that are farther away. Can we deliver artillerylike effects without an artillery cannon? What else can we put in the weapon round to make it infallible? Can weapons talk to each other on the fly? Can these collective communications be made to resist misinformation?
To address these questions without clear answers, we have to think in terms of the outcomes that will best serve combatant
commanders. For instance, scientists are taking steps to design approaches to disable enemy equipment that is fixed, hiding, moving or attacking at a high rate of fire and volume.
Te U.S. must recapture overmatch and avoid technological surprise by empow- ering Soldiers with the capabilities of a main battle tank, empowering squads with the full flexibility of combined arms and empowering armored brigades with full freedom of maneuver in the most challenging environments.
Our intention is to develop the science to enable battlefield assets to be effec- tive in dispersed positions. Tis requires weapon systems that communicate with one
another, make autonomous deci-
sions and maneuver to provide desired effects. By combining various weapons over the distributed battlespace, work- ing together to provide the right lethal or
nonlethal effects on target, Soldiers will deliver fewer high-explosive rounds that are more precise.
THE HURDLES WE FACE Technical gaps exist between the desired and current states of U.S. land forces’ capability to implement distributed and cooperative engagement in contested environments. ARL improves the odds of technological success by identifying technology gaps and conducting basic research from the earliest stages of the technology life cycle.
Here are four known barriers to realizing the capability:
Navigation: Navigation is the fundamen- tal feedback required to deliver weapons on the battlefield. Advances in weapon navigation are hindered by technical limi- tations associated with algorithms, sensing on dynamic vehicles, real-time process- ing, cost and extreme weapon dynamics. Some weapons are subject to accelerations 100,000 times the acceleration of gravity from being launched to speeds four times the speed of sound. Other weapons are spun thousands of times per second to maintain flight stability—to fly accurately
A COMPLEX FUTURE
ARL uses defense high-performance computing, advanced computational fluid dynamics and other techniques to model aerodynamic interactions. Future engagements will likely employ weapons that incorporate advances in propellants and aerodynamics to allow them to maneuver and change course based on a commander’s guidance. (SOURCE: ARL)
