Dstl future UGV

The UK’s Defence Science and Technology Laboratory (Dstl) has initiated a study into future UGV (unmanned ground vehicle) concepts that will investigate cost-effective solutions to protect the vehicles from threats, including specific armour and technology that will ensure high levels of mobility, survivability and mission availability to support crewed platforms in battlefield warfare.

The work has been carried out in conjunction with a consortium led by RBSL, with Prodrive, ARKE, ThinkCreative, Cranfield University and BAE Systems as key partners. The concept study has focused on two timescales, the near-term which addresses solutions that could be realised using currently available or mature technologies, and the longer term looking at technologies that are likely to be available 10 years or further ahead. The focus has been on medium weight platforms of around 2-5 tonnes, which have been a recent subject of interest due to the useful payloads they can carry.

Modern trends utilise UGVs as platforms for key combat capabilities such as resupply, casualty evacuation, reconnaissance, weapons platforms, decoys and communication nodes. The vehicles are thus becoming core elements of a deployed capability, and will be carrying expensive assets. Although it will be acceptable to take higher risks with uncrewed platforms than with crewed platforms, they can no longer be considered as ‘disposable’ assets and if they are to support missions across the full spectrum of operations they must be able to fully protect and keep station with the crewed platforms they support.

A key challenge of the study has been improving the mobility and survivability of platforms without compromising payload. Further challenges arise from the desire to provide an amphibious capability for river crossing and littoral operations.

In order to meet the demanding, and conflicting requirements, novel modular concepts have been developed which would allow platforms to be configured in theatre to meet specific mission requirements. In order to meet the mobility requirements and enable the smaller UGV platforms to keep station with larger crewed platforms, novel wheel and tracked suspension systems have been designed and modelled.

Matt Askroyd, project lead at Dstl, commented: “When UGVs were first fielded, it was usually for dangerous tasks such as deactivation or destroying Improvised Explosive Devices with the goal of removing the operators from harm’s way and accepting the device itself was at risk of damage or destruction. As thinking on the use of UGVs evolved, the focus moved to so called ‘Dull, Dirty and Dangerous’ tasks such as route proving, contaminated ground reconnaissance and decontamination.”

“This is very exciting work. As well as enhancing mobility, the novel suspension systems significantly improve the ride, and hence improve reliability and provide a stable sensor and weapon platform. The use of armour protection for key components and enhanced signature management systems to exploit the benefits of the small platform size have been explored, along with weight and cost effective means to provide robustness, redundancy and fall-back modes.”
