Haemorrhaging is a leading cause of preventable death for soldiers in combat. This is particularly acute for non-compressible areas, such as the groin, trunk, armpit, neck and internal organs, as compression packs routinely carried by soldiers don’t work on these types of bleed.
To solve this problem, researchers are developing a new type of liquid, called Statbond, that could be put directly onto a wound without the need for compression to stop or slow bleeding long enough for the patient to reach a hospital. Based on visco-liquid haemostatic agents, which can penetrate deep into a wound and seal against fluid loss, the technology helps natural blood-clotting cascade to happen against the surface of the gel.
“This is particularly important for injuries to arteries which are linked directly to the heart and pulse, interfering with clot formation,” explains Dr Robert Mantz, a chemistry branch chief with the Army Research Lab, which is developing the technology with Hybrid Plastics, the University of Mississippi Medical Center, Vanderbilt University and Ichor Sciences.
The solution, which recently completed successful animal studies, is currently undergoing a phase II enhancement study and FDA registration. It’s expected to be available for physicians in 2022 and potentially carried by soldiers in the form of a durable pocket-carry squeeze pack by 2025.
“We want to make sure an average person with very limited training could apply this and it would have efficacy,” adds Mantz.
Also addressing blood loss, in the UK researchers at the University of Bristol are looking at ways to make blood transfusions during combat easier. They’re conducting trials on how to ‘grow’ and mature red blood cells in the laboratory with funding from the government’s Defence Science and Technology Laboratory.
This manmade blood could potentially be administered to anyone, regardless of their blood type, and freeze-dried for easy storage and transportation. This would be especially useful in combat situations, considering seven years of British ops in Afghanistan saw around 15,500 litres of blood transfused to 2,600 patients. However, trials are in the early stages and could take a decade to develop.
The US Department of Defense’s (DoD) Joint All-Domain Command and Control (JADC2) project is quite possibly its largest-ever IT modernisation programme. It will mean that data from all six US Armed Forces will be accessible in one platform, covering everything from fighter jets, submarines, and tanks, to even potentially individual troops in the field.
The intention behind the project is to provide the US Military with a significant advantage and offer commanders a greater insight into what is happening in both their field of operations and the wider operational context. But while the general concept may be simple enough to explain, the project itself remains complex.
On 13 May, US defence secretary Lloyd Austin signed off the strategy for JADC2. While full details about what it contains have not yet been made public, that approval represented a significant step forward for the project. However, myriad hurdles remain.
At present, data sharing in the US Armed Forces is largely fragmented. Applications can vary between branches of the armed forces and there is little interoperability between computer systems. Then there are the varying operational requirements of each service.
Crucially, what has held JADC2 back is the absence of any tactical enterprise cloud solutions capable of meeting the considerable demands for data and bandwidth.
Justin Bronk, research fellow for airpower and technology in the Royal United Services Institute military sciences team, claims that the sheer volume involved in collecting all the data produced by an F35 fighter jet, for example, is ‘probably impossible from a bandwidth perspective.
“You might be able to do it with laser comms or something, but even then, you're talking about alignment problems. And you're talking about a link that you might be able to establish temporarily for a specific purpose,” suggests Bronk. “But the idea that everything's going to be able to share everything all the time is completely impossible for a whole host of bandwidth and physics-related reasons.”
Regardless of the challenges, the US Government is pushing ahead with the project, not least to avoid falling behind China in the technological arms race.
