MilDef Generic Vehicle Architecture capabilities and products

Generic Vehicle Architecture history

Military vehicles are typically in-service for many years and are subject to significant through-life updates. There is often a need to upgrade these platforms quickly in order to address new threats and scenarios. However, with a number of different systems, sub-systems and products from multiple sub-contractors, these upgrades can become complex and expensive.
The Generic Vehicle Architecture (GVA) approach, originally conceived by the UK Ministry of Defence, is a concept of generic design principles for the electronic and power architectures as well as Human Machine Interface for military vehicles. Introduced in 2010, the GVA standard (Defence Standard 23-009) was first implemented on the British Army Foxhound Vehicle.
NATO observed these activities and introduced the ‘NATO Generic Vehicle Architecture (NGVA) for Land Systems’ (STANAG 4754) in 2018. Australia also followed with the ‘Australian Generic Vehicle Architecture’ (AS GVA) the same year.

MilDef’s role in the GVA story

The launch of the GVA standard in UK coincided with MilDef opening its UK facility in Cardiff and MilDef was soon contracted to develop the GVA Ethernet Switch for the Foxhound Vehicle. This switch has been in service for 10 years and has shown incredible reliability with the Foxhound fleet operational throughout the UK’s operations in Afghanistan. With this vehicle now due for upgrade MilDef is able to offer a fit, form and function replacement proving the GVA philosophy as well as MilDef’s ability to support its products through the vehicle’s service life.

More recently MilDef has been awarded a circa £20m contract from Rheinmetall BAE Systems Land (RBSL) and Rheinmetall Landsysteme GmbH to provide GVA compliant Crewstation PCs, Servers and Ethernet Switches for the British Army Mechanised Infantry Vehicle (MIV) Boxer programme.
