U.S. Army to integrate power cables into a tactical vest

The U.S. Army has announced plans to integrate flexible, power cables into a tactical vest used by Soldiers.

Currently, Army engineers and scientists faced with the need to expand the capabilities of soldiers on the modern battlefield. Every day, more and more powerful and versatile weaponry, modern systems and gadgets will be included in the personal equipment, which, in turn, requires solutions to ensure their recharge.

Combat Capabilities Development Command’s (CCDC) Command, Control, Communications, Computers, Cyber, Intelligence, Surveillance and Reconnaissance (C5ISR) Center has partnered with the CCDC Soldier Center to investigate integrated power solutions in support of programs across the Army. These include Nett Warrior, Next-Generation Squad Weapons (NGSW) and Integrated Visual Augmentation System (IVAS).

As the Army has increased the number of electronic devices that Soldiers need to carry, more cables have been required to connect equipment to power sources and share data. In addition, the Army’s modernization initiatives will demand continually increasing rates of Soldier-worn power.

The integrated cables are one solution that researchers are developing for a holistic approach.

“This new flexible cable is up to 50 percent lighter than the legacy version,” said Ethan Wise, a C5ISR Center electronics engineer who is leading the project. “It’s much more flexible, less bulky and removes cabling that encumbers a Soldier’s motion when connected to a Conformal Wearable Battery.

“It reduces snag hazards because it can be looped through a tactical vest several times. The new cable feels like the fabric of a standard Army uniform and blends in seamlessly with the camouflage pattern,” said Wise.

A United Kingdom company initially developed the new cable, and the U.S. Army has been investigating its potential uses through the Foreign Comparative Testing program. FCT works with Army science and technology organizations to find and evaluate solutions to meet the operational needs of U.S. Soldiers regardless of the technology’s country of origin.

The FCT program initially focused on the Nett Warrior system, and the CCDC team is now leveraging that science and technology knowledge for high-priority projects such as NGSW and IVAS.

IVAS is a Microsoft-designed heads-up display that functions as a fight-rehearse-train system, among other roles. Its high-tech features, such as augmented reality and aided target recognition, will require continuous power loads for extended periods of time. Wise noted that flexible cables are a potential fit for power delivery within this program.

For the NGSW project, researchers are investigating a rifle sling composed of similar materials as the new cables, according to C5ISR Center research mechanical engineer Dr. Nathan Sharpes. The benefits would include reduced battery weight on the weapon, more flexibility and greater run times.

In addition to the sling, Sharpes and his colleagues are prototyping new ways of storing energy and routing power on the weapon. These features collectively give the Soldier options to power weapon-mounted enablers to meet changing mission requirements.

“These new weapons will be equipped with sophisticated technologies, likely requiring more power,” Sharpes said. “The straight forward solution would be to tether the weapon to a larger battery on the vest. However, this introduces a snag hazard and historically hasn’t been popular among Soldiers. Routing power through the sling should yield a more acceptable and familiar-feeling solution.”

C5ISR Center engineers will continue to work on prototypes throughout 2020 for potential use with IVAS and NGSW program offices.
