Protector: The RAF’s Next-Generation Armed Drone for Persistent ISR and Precision Strike

Overview

The MQ-9A Reaper has been one of the most significant capabilities in the RAF’s recent operational history, accumulating over 145,000 operational hours across Afghanistan, Iraq, Syria and other theatres since 2007. Its replacement, the Protector RG Mk1, takes that legacy and transforms it. Based on General Atomics’ MQ-9B SkyGuardian, Protector provides over 40 hours of endurance, a range exceeding 6,000 nautical miles and operation at altitudes up to 40,000 feet — a step change in persistent intelligence, surveillance and precision strike capability.

Protector delivers a combination of persistent ISR and precision strike using MBDA Brimstone 3A missiles and Raytheon UK Paveway IV guided bombs. It is the world’s first remotely piloted aircraft system certificated to both NATO STANAG-4671 and UK MOD DEF STAN 00-970 airworthiness standards, enabling it to operate in non-segregated civil airspace — a capability that no previous armed drone has achieved. This certification opens up operational possibilities that were previously impossible, including operations from UK and allied airfields without the airspace restrictions that confined Reaper to dedicated military ranges and overseas theatres.

The RAF has contracted for sixteen aircraft plus seven ground control stations, synthetic training systems and support infrastructure. UK-specific enhancements include X-band SATCOM, advanced data links, UK weapons integration and the Protector International Training Centre at RAF Waddington. Initial Operating Capability was achieved in 2025, with Full Operating Capability expected in 2026.

Strategic Purpose and Objectives

Persistent, Certified and Globally Deployable

Protector addresses critical UK requirements for persistent ISR and precision strike supporting global operations. Key drivers include over 40 hours of operational persistence enabling continuous coverage, global reach with extended range and SATCOM, precision strike with Brimstone and Paveway integration, world-first airworthiness certification for civil airspace operations, and multi-mission flexibility including search and rescue and disaster response.

The programme also has a significant international dimension. The UK and Belgium have established an MQ-9B International Cooperative Program, and the UK is a founding member of the NATO MQ-9 International Cooperation Support Partnership established in July 2024. Protector forms part of the RAF’s evolution toward autonomous collaborative platforms, serving as both an operational capability and a stepping stone toward the next generation of unmanned and autonomous air systems.

31 Squadron, reformed at RAF Waddington in October 2023, operates Protector. The establishment of the Protector International Training Centre at Waddington creates a centre of excellence for MQ-9B operations that will serve both UK and allied operators, generating institutional expertise and international partnerships that extend well beyond the platform itself.

Budget and Financial Structure

Programme Value

The initial production contract was awarded in July 2020 at £65 million for three aircraft and ground control stations. The total fleet of sixteen aircraft with seven ground control stations is estimated at £250–350 million. The UK PASS support contract, signed in June 2025, is estimated at £500–750 million over ten years. Through-life programme cost is estimated at £1–1.5 billion over a twenty-year lifecycle, including aircraft, ground systems, training, infrastructure and sustainment. UK industrial content includes components from the Isle of Wight and weapon systems from MBDA and Raytheon UK.

Budget Division and Holder

The RAF is the primary operating command and capability sponsor. Defence Equipment & Support manages contract administration and acquisition oversight. MOD Commercial provides commercial strategy. Strategic Command coordinates joint force requirements. RAF Air Command holds the operational budget and capability authority, with DE&S managing procurement contracts with General Atomics Aeronautical Systems as prime contractor. MBDA and Raytheon UK provide weapon systems under separate contracts.

Procurement and Acquisition

Acquisition Pipeline

Protector is in delivery and operational fielding. Initial Operating Capability was achieved in 2025, with Full Operating Capability expected in 2026. Key milestones include the programme announcement in October 2015, the initial contract in July 2020, the option exercise for an additional thirteen aircraft in July 2021, first UK delivery to RAF Waddington in September 2023, 31 Squadron reformation in October 2023, UK Military Type Certificate in May 2025, and the UK PASS support contract in June 2025.

Tender Information

The programme was announced in October 2015 by Prime Minister David Cameron, with the initial contract awarded in July 2020 and the option for additional aircraft exercised in July 2021. General Atomics Aeronautical Systems is the prime contractor. UK suppliers include MBDA for Brimstone and Raytheon UK for Paveway IV, plus communications and support service providers. The NATO MQ-9 International Cooperation Support Partnership was established in July 2024, creating a framework for allied cooperation on the platform.

Why It Matters

Protector represents a generational leap in the UK’s remotely piloted aircraft capability. Where Reaper was a platform adapted from US operations and confined to overseas theatres, Protector is a UK-configured, globally deployable, airworthiness-certified system that can operate from home bases and allied airfields worldwide. Its 40-plus-hour endurance means that a single aircraft can provide continuous surveillance over an area of operations for nearly two days, delivering a persistence that manned aircraft simply cannot match.

The programme’s significance extends beyond the platform. Protector’s airworthiness certification sets a precedent for future unmanned systems, demonstrating that remotely piloted aircraft can meet the same safety standards as manned platforms. Its international cooperation frameworks create a model for allied collaboration on unmanned systems. And its integration with UK weapons, communications and data systems ensures that it is not simply a foreign platform in UK service but a genuinely British capability embedded in the wider force structure.

For industry, Protector offers substantial and sustained opportunity in platform support, weapons integration, ground control systems, SATCOM, data links, training systems, synthetic environments and through-life sustainment. The £500–750 million PASS support contract alone represents a decade of committed spending. UK suppliers including MBDA, Raytheon UK and communications providers are integral to the programme, and the international cooperation dimension creates opportunities for UK companies to support allied operators. As the RAF evolves toward autonomous collaborative platforms, Protector’s industrial base will be well positioned for successor programmes.
