Multi-Mode Radio: The Software-Defined Radios That Will Replace Bowman on the Battlefield

Overview

While Bowman BCIP 5.7 sustains today’s tactical communications, the Multi-Mode Radio programme is building tomorrow’s. MMR is a critical component of the Morpheus tactical communications programme, delivering software-defined radios capable of operating across multiple waveforms simultaneously. These radios will provide tactical voice and data communications for dismounted soldiers and vehicle-mounted platforms, replacing the legacy Personal Role Radios and vehicle radios that have served the British Army for over two decades.

L3Harris has been selected as the preferred bidder for the Morpheus MMR. The radios will operate NATO standard waveforms, ensuring coalition interoperability — a critical requirement as UK forces increasingly operate alongside allies in joint and combined operations. The software-defined architecture means that these are not simply replacements for existing hardware; they are fundamentally different devices that can be updated, reconfigured and upgraded through software rather than physical modification.

MMR sits within the broader LETacCIS transformation, delivering secure, resilient and interoperable tactical communications across British Army formations. It is one of several Morpheus sub-programmes — alongside Trinity, the Battlefield Management Application and Dismounted Situational Awareness — that together will deliver the next-generation tactical communications environment for UK land forces.

Strategic Purpose and Objectives

Flexible, Interoperable and Software-Upgradeable

MMR is a fundamental enabler for Army tactical communications modernisation. It delivers soldier and vehicle connectivity as the backbone of the Morpheus programme, replacing ageing Bowman radios with flexible, modern capability. The key drivers are waveform flexibility enabling multiple communication modes, NATO interoperability through standard waveforms, increased bandwidth for data-heavy applications, enhanced encryption and cyber resilience, and a software-upgradeable architecture that reduces obsolescence.

The software-defined nature of MMR is strategically significant. Legacy radios are hardware-defined — their capabilities are fixed at the point of manufacture, and upgrades require physical replacement. Software-defined radios can be updated remotely, receive new waveforms and encryption standards, and adapt to changing operational requirements without replacing the physical device. This approach dramatically reduces through-life costs, extends equipment lifespan and ensures that the Army’s radios can keep pace with evolving threats and allied communications standards.

MMR supports the Future Soldier concept, multi-domain integration and coalition operations alongside NATO allies. In an operational environment where communications security, bandwidth and interoperability are increasingly contested, the ability to field radios that are flexible, resilient and continuously updated is not a luxury — it is a tactical imperative.

Budget and Financial Structure

Programme Value

MMR forms part of the overall LETacCIS programme, valued at £2–3 billion over ten years. The individual MMR contract value is estimated in the hundreds of millions, with the L3Harris Morpheus MMR contract anticipated to represent a significant portion of overall programme investment. Ongoing sustainment and technology refresh are included in through-life cost projections.

Budget Division and Holder

Defence Digital holds programme ownership. Army Command provides user requirements. DE&S manages contract administration. Strategic Command coordinates joint force requirements. Budget holder responsibility sits with Defence Digital and the BATCIS Delivery Team, with DE&S Land Equipment Operating Centre managing procurement contracts with L3Harris as preferred bidder.

Procurement and Acquisition

Acquisition Pipeline

MMR is in the procurement phase, with L3Harris selected as preferred bidder. The contract award is expected to enable initial operating capability by the late 2020s, integrated with the broader Morpheus rollout timeline targeting Full Operating Capability between 2030 and 2035. The programme is tracked within the LETacCIS digital transformation pipeline.

Tender Information

L3Harris has been announced as the preferred bidder for the Morpheus MMR following competitive procurement conducted through the MOD Defence Sourcing Portal. Contract details are available through the Defence Sourcing Portal and DE&S procurement records as part of the wider Morpheus programme contracting. The competitive procurement process reflects the MOD’s commitment to breaking the single-vendor model that characterised the original Bowman contract.

Why It Matters

MMR is the programme that puts next-generation communications into the hands of the individual soldier and onto every vehicle in the British Army. While BCIP 5.7 keeps Bowman working today, MMR is the future — the radios that will carry voice, data and situational awareness across the digitised battlefield of the 2030s and beyond. The transition from hardware-defined to software-defined radios is one of the most significant shifts in tactical communications in a generation, and MMR is the programme delivering it for the UK.

The selection of L3Harris as preferred bidder also signals a shift in the industrial landscape. The original Bowman contract established General Dynamics UK as the dominant player in UK tactical communications. MMR’s competitive procurement and the selection of L3Harris introduces a new prime into this critical market, with implications for supply chains, technology partnerships and the broader industrial base. For the MOD, this diversification reduces single-vendor risk and brings fresh innovation to a domain that has been dominated by a single contractor for over two decades.

For industry, MMR represents substantial opportunity in software-defined radio technology, waveform development, NATO interoperability solutions, encryption and cyber resilience, antenna systems, power management, ruggedisation, platform integration and through-life support. The programme’s scale — equipping the entire British Army with new tactical radios — and its integration with the broader LETacCIS portfolio ensure that supply chain opportunities will be significant and sustained. Companies with expertise in software-defined communications, military-grade radio technology and coalition interoperability will find MMR a programme of considerable strategic importance.
