Despite an increasing focus on SMEs, effective industrial mobilisation must also better harness the power of traditional defence firms. Andrea Thompson from BAE Systems explains how.

The excitement in defence ministries about improving how they engage with dynamic and innovative small and medium enterprises (SMEs) is understandable but represents only a partial element of what is needed for industrial mobilisation. As Christian Broze explained in the previous episode, the traditional defence primes remain crucial actors and often have the capacity for mass that SMEs lack.

Effectively engaging industry in the plans for growth of defence capacity that have been touted in defence reviews has to be multi-faceted, acknowledging the heterogenous nature of industry as a whole and responsive enough to accommodate the differences between distinct parts of the same enterprise.

Andrea Thompson offers the perspective of a large defence prime, drawing on her experience as Group Managing Director for BAE Systems' Digital Intelligence. With a career spanning the UK and US, she has worked at Rockwell International, Rolls Royce and BAE Systems, including in BAE's F-35 and Eurofighter Typhoon programmes, and as the Chair of the Eurofighter Supervisory Board for the Eurofighter GmbH consortium. She was named in the Financial Times' UK Top 100 list of Most Influential Women in the Engineering Sector in 2019.

The preparedness of Western armed forces for conflict is something that has featured prominently in many defence reviews.

Christian Brose, Anduril's President & Chief Strategy Officer, describes how governments can build effective relationships with innovative, disruptive small and medium enterprises (SMEs) in the defence industrial ecosystem, and how they can develop new strategies for achieving greater military capability to meet preparedness requirements.

It is clear there is no one-size-fits-all approach; Christian argues that today, government and the defence industry need to follow traditional approaches where that makes sense, and more modern, adaptive approaches for equipment that is designed to be scaled and mass produced without imposing huge investment and talent costs on suppliers.

Christian is the President and Chief Strategy Officer at Anduril Industries, prior to which he was Staff Director of the Senate Armed Services Committee.

Rear Admiral Archer M Macy Jr describes today's military, organisational, human and cultural risks and opportunities in integrating forces for air and missile defence.

Many modern defence reviews focus on the need for integration. Arguably, nowhere is the need more important today than in providing air and missile defence. State and non-state adversaries have shown varying abilities to combine their attacks in ways that pose multiple dilemmas.

Using small, slow-moving and low flying drones intended to swamp defences, coordinated with aircraft and cruise, hypersonic and ballistic missiles, these packages present huge challenges across a wide span of heights, speeds and trajectories. As well as being a problem for fielded forces, it is an industrial challenge in making sure there are enough interceptors at the right price point to sustain the defences.

In this episode, RAdm Macy USN (Retd) offers his unique perspective on the challenges and opportunities based on his time in the Aegis Program Office and most recently as the Director of the Joint Integrated Air and Missile Defense Organization in the US Joint Staff.
