MULTIDOMAIN DOMINANCE
During the demonstration, an operator used throttle and steering input inside the vehicle to drive while it was secured to the dyna- mometer. In a feedback loop, the vehicle’s steering and engine output were measured on the dynamometer and returned to the simulated test environment, changing the simulation output. Te live tactical vehicle could be seen moving in the simulated scene and the movement drove changes with live or virtual threats or entities in the simulation.
“In this thread we demonstrated an electronic warfare attack on the vehicle to see how it would impact the convoy. Using a live jammer in the EMI chamber, we jammed the tactical vehi- cle’s fielded GPS and radio systems. Ten, you could see in the simulation where the live vehicle lost contact with the simulated convoy. Te live vehicle was no longer visible on the tactical screens and the operator driving the system lost situational aware- ness of their position,” Weimer said. “Te objective of the test was
to measure the time for the operator to regain situational aware- ness and communication with the convoy. I think it is important to be able to see the effect of a threat beyond just the effect on an individual system. In traditional developmental testing, my focus would just be the effects on the live system in the chamber, but with the LVC environment we were able to see the effects on the live vehicle and how that effect impacted the overall tactical operation. We can now learn the broader impacts of that elec- tronic warfare attack on the entire formation and operation.”
JOINT FORCE PLANS Operating as a joint force within the military is nothing new, but doing it seamlessly, in all domains, is a new challenge. ATEC’s ability to simultaneously test with both live and virtual assets while providing real-time data and results gives the Army a leading edge in experimentation, training and testing. “We’ve always been able to do live testing, virtual [only] testing, and use
MISSION ACCOMPLISHED
Paladin howitzers prepare to receive a fire mission during exercise Combined Resolve 18, held in May 2023 in Hohenfels, Germany. The exercise included more than 4,000 service members, allies and partners from 15 countries, and was designed to assess units’ abilities to conduct combat operations in a multidomain battlespace.
