T&E Transformation: Reinventing How Defence Tests, Certifies and Fields New Capabilities

Overview

Before any new military capability reaches the front line, it must be tested, evaluated and certified. That process — Test and Evaluation, or T&E — is one of the most critical and least visible functions in Defence. It ensures that weapons work as intended, platforms are safe to operate, software behaves predictably and new technologies can be integrated with existing systems. Get it right and forces deploy with confidence. Get it wrong and lives are at risk.

The challenge is that the traditional approach to T&E was designed for a world of relatively stable technology cycles and long procurement timelines. Today, the MOD needs to field AI systems, autonomous platforms, digital twins and rapidly evolving software at a pace that legacy test processes simply cannot match. T&E Transformation is the MOD’s answer: a major, multi-year programme to modernise every aspect of how Defence tests, certifies and fields new capabilities — from infrastructure and regulation to digital tools and workforce skills.

The programme encompasses new infrastructure, digital-first processes and regulatory reform. Its centrepiece is the £4.5 billion Defence Test & Evaluation Services (Future) Contract, covering the period 2029–2044, which will reshape T&E service delivery for a generation. Alongside this, the MOD is creating a digital T&E marketplace for public and private sector access, launching regulatory sprints to clear barriers and accelerate commercial and SME access — with an early focus on autonomous systems — and developing the Range of the Future programme at Dstl to build and de-risk next-generation T&E technologies and facilities.

Strategic Purpose and Objectives

Testing at the Speed of Relevance

T&E Transformation exists to ensure that the MOD can certify and adopt new technologies safely and legally at the speed of relevance. In practical terms, this means replacing live trials — which are expensive, time-consuming and increasingly unable to replicate the complexity of modern operations — with virtual test ranges, digital twins, high-fidelity simulation and digital evidence frameworks. The MOD is embedding requirements for digital twins and evidence provision in all new contracts, ensuring that future capability growth, product management and compliance are digitally enabled from the outset.

The programme is also opening the T&E environment to a broader ecosystem of participants. Mobile test capability is being rolled out to increase SME and new entrant opportunity, particularly for uncrewed systems. The digital T&E marketplace, due in 2026, will allow both public and private sector organisations to access test services in ways that were previously restricted to established defence contractors. Regulatory sprints are addressing the barriers that have historically made it difficult for innovative companies to engage with Defence testing — a deliberate effort to bring commercial agility and fresh thinking into a domain that has traditionally been slow to change.

T&E plays a central role in major platform and digital strategies, including the Autonomous Collaborative Platform programme, synthetic training and the Digital Warfighter initiative. It is being positioned as a joint, enterprise-wide service that integrates seamlessly with acquisition, innovation and rapid delivery cycles. The programme is governed by the National Armaments Director and delivered by DE&S, Dstl, ASWC and Defence Digital, with close links to digital skills upskilling and the Regulatory Solutions Hub for user support.

Budget and Financial Structure

Programme Value

The long-term Defence Test & Evaluation Services (Future) Contract is valued at £4.5 billion, covering a fifteen-year period from 2029 to 2044. Additional investments are directed towards T&E digital marketplaces, digital twin and virtual range capabilities, SME and mobile technology access, regulatory reform, the Regulatory Solutions Hub, training, and digital evidence frameworks. The combined scale makes T&E Transformation one of the most substantial capability enabler programmes in the Defence portfolio.

Budget Division and Holder

DE&S leads on T&E Transformation delivery. The National Armaments Director provides strategic oversight and governance. Strategic Command and ASWC act as domain leads, while Dstl drives the Range of the Future programme and innovation. Defence Digital is responsible for digital evidence and integration, and MOD Commercial handles procurement. Budget holder responsibility is shared between the NAD for strategy and oversight, DE&S for programme management and contract delivery, Dstl and ASWC for capability and technology innovation, and Defence Digital for digital certification and enablers.

Procurement and Acquisition

Acquisition Pipeline

T&E Transformation services and contracts — including the Defence Test & Evaluation Services (Future) Contract, marketplace platforms, digital twin and virtual range capabilities, regulatory sprint outcomes and the Range of the Future — are all tracked in the MOD pipeline, with regular updates via the Defence Sourcing Portal and Strategic Command and Dstl calls for proposals.

Tender Information

The tender for the £4.5 billion Defence Test & Evaluation Services (Future) Contract commences in August 2029, with a contract duration of 180 months. T&E marketplace and digital twin pilots are running from 2025–2026. Regulatory reform and the Range of the Future programme launched in 2025. RSH and digital skills contracts are ongoing. Tender references are held in Defence Sourcing Portal entries for new T&E, digital twin, SME and mobile test, evidence digitisation and Range of the Future components, under Dstl, DE&S and NAD programme office identifiers.

Why It Matters

T&E Transformation is critical to the MOD’s ability to keep pace with technological change, lower cost and risk, and accelerate the journey from concept to operational capability. Without a modern T&E framework, even the most advanced technologies cannot be certified, cleared and fielded — leaving Defence unable to exploit the innovation it has paid to develop. The programme ensures that the UK can test and adopt AI, autonomous systems, digital twins and rapidly evolving software safely, legally and at the speed that modern warfare demands.

The programme is also central to achieving Defence’s wider digital, industrial and acquisition reform ambitions. By opening the T&E environment to broader ecosystems — including SMEs and non-traditional defence companies — and by prioritising digital-first and virtual solutions, T&E Transformation is helping to create a more competitive, agile and innovative Defence industrial base. The emphasis on digital twins, virtual ranges and digital evidence is not simply about efficiency — it is about ensuring that the UK retains the ability to innovate, certify and field new capabilities faster than its adversaries.

For industry, the programme offers generational opportunities. The £4.5 billion Future Contract alone represents one of the largest single T&E procurements in UK defence history. Beyond that headline figure, the digital T&E marketplace, virtual range development, digital twin integration and mobile test capability create sustained demand for companies with expertise in simulation, AI, cloud computing, data engineering and advanced analytics. The deliberate effort to lower barriers for SMEs and new entrants means that the opportunity extends well beyond traditional T&E providers — making this a programme to watch for any company with innovative test, certification or digital solutions.
