NATICK, Mass. (March 10, 2015) — The U.S. Army is streamlining efforts to provide squad- and platoon-level ground Soldiers, operating in austere environments, with an organic aerial resupply capability that will empower and sustain them on the battlefield.
The Enhanced Speed Bag System, or ESBS, fills this capability gap by drastically increasing the survivability rate of critical resupply items such as water, ammunition, rations and medical supplies, which must be air-dropped from helicopters to small units on the ground. The system includes a hands-free linear brake, rope, and a padded cargo bag that can hold up to 200 pounds and be dropped from 100 feet.
ESBS was originally developed by engineers, from the Natick Soldier Research, Development and Engineering Center, or NSRDEC’s, Aerial Delivery Directorate and the Armament Research, Development and Engineering Center, or ARDEC’s, Logistics Research and Engineering Directorate to standardize the improvised airdrop methods used in theater to resupply units in remote locations, where traditional resupply methods, such as truck convoys, are too impractical or threat laden.
“The goal was to standardize ad hoc techniques used with body bags and duffel bags by providing a material solution and giving units enough knowledge and training to utilize it,” said Dale Tabor, NSRDEC’s aerial delivery design and fabrication team leader.
“We originally received this need from the field, specifically for emergency ammunition resupply,” said Bob Forrester, an engineer with ARDEC’s Logistics Research and Engineering Directorate at Picatinny Arsenal, New Jersey. “We received the requirements, found the funding, and teamed with Natick as the technical lead.
“Essentially, we worked the ammunition survivability piece, and NSRDEC worked the aerial delivery piece,” Forrester said.
At an evaluation conducted in July 2013 on Fort A.P. Hill, Virginia, teams packed six ESBS cargo bags with 12,720 rounds of ammunition, each distributed based on a squad-level basic load, and dropped from a 100-foot crane. They thoroughly inspected the rounds and conducted a live fire to determine the ammunition system’s effectiveness.
The results were a 98-percent survivability rating of ammunition dropped with the ESBS – a vast improvement from the 50-60 percent experienced with ad hoc methods.
Subsequent evaluation at Army Expeditionary Warfighting Experiment Spiral I 2014 prompted ARDEC to “recommend the immediate fielding of ESBS to deployed Soldiers,” Forrester said.
“What we have done is taken resupply to the lowest possible level – the squad and platoon levels,” Tabor said.
“Soldiers at unit level are trained how to get the system packaged, loaded in the aircraft, and delivered,” Tabor said. “In this way, ESBS provides an organic resupply capability.”
Advancement of the system gained increased momentum through the involvement of the U.S. Army’s Rapid Equipping Force, or REF, an organization uniquely chartered to combine requirement validation, acquisition authority and flexible funding under one roof.
