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.

Air Chief Marshal Hugh Dowding's air defence system was crucial during the Battle of Britain. The RAF Museum's Andrew Renwick describes how it was created.

In the 1930s, Great Britain, wrestled with the challenge of achieving wide area air defence to protect against threats from continental Europe while reliant on many different elements.

ACM Hugh Dowding was tasked with solving this problem. His solution was a system that integrated detection systems, including classified intelligence sources and the new radar technology, with disaggregated command and control systems directing fighters onto the enemy. It was this 'Dowding System' that underpinned British success in the Battle of Britain.

As Winston Churchill put it: 'All the ascendancy of the Hurricanes and Spitfires would have been fruitless but for this system, which had been devised and built before the war.'

As European nations discuss preparing their militaries for war, Poland's former Chief of Defence, General Rajmund Andrzejczak, describes how they have led the way in increased military spend.

With almost 5% of its GDP now invested in defence, Poland has moved at speed to grow its armed forces. Indeed, Poland stands out as the European NATO member that has moved fastest to respond to the threats facing the Alliance and is rapidly becoming a European leader in defence.

In this episode, we talk to General Andrzejczak, the Chief of General Staff for the Polish Armed Forces between 2018 and 2023. It was while he was Poland's most senior military officer that preparations to face the new threat posed by Russia in Europe were accelerated.

He describes the opportunities and challenges in the transformation implemented across the physical, moral and conceptual components of Polish fighting power and what is still needed for NATO to deliver on its ambitions.

He also discusses how the European members of NATO might meet the Russia threat and respond to 'the strategic double espresso' of the 2025 US National Security Strategy.

A graduate of Poland's National Defence Academy, the Czech Army Defence Academy, and the Royal College of Defence Studies in London, General Andrzejczak is an expert commentator on European defence and security.

How did Prussia turn from a beaten underdog into the leader of a united Germany following its victories of the 19th century?

In this episode, Geoffrey Wawro, Professor of Military History at the University of North Texas, joins Beatrice and Paul to discuss Helmuth von Moltke the Elder, Chief of Staff of the Prussian Army from 1857–71.

Given the limited funding available to Prussia, von Moltke the Elder successfully advocated for investments in essential infrastructure and the weapons with the greatest effect, rather than spreading funds thinly and ineffectively.

Professor Wawro explains how Prussia emerged victorious from three successive wars in Denmark (1864), Austria (1866) and France (1870-71), the role of education and how the military adapted to new technology on all levels.

Often seen as the gold standard for societal resilience, Finland has many admirers. The Secretary General of its Security Committee, Petteri Korvala, describes Finland's approach.

Many nations are exploring how to build societal resilience as part of a comprehensive approach to security. The Scandinavian countries are often seen as exemplars of best practice, with Finland arguably leading the pack. But delivering resilience through comprehensive security requires trust across all elements of society and a cultural shift as much as it needs the right structures and processes.

In this episode, we hear from the Secretary General of Finland's Security Committee, Petteri Korvala, about how their comprehensive security system works.

Petteri Korvala has over 30 years of experience in Finland's defence forces and internationally, including in the Ministry of Defence and in Finland's Permanent Representation to the European Union, as well as having served as a liaison officer in United States European Command.

Britain was not ready for the First World War but some key, if embryonic, plans and capabilities proved vital. Sir Hew Strachan discusses the lessons for today.

With concerns rising about how ready Western nations are for the risk of war in Europe, we discuss the lessons from Britain's preparation for The Great War. And while preparation is important, not all actions to prepare are equally important. In this case, Britain was not fully prepared but had taken some initial steps that were important in allowing the country to accelerate towards preparedness.

The crucial elements concerned the ability to engage society, coordinate across government and ensure a robust industrial base that supported the armed force that drew on the talent of regular and volunteer forces. As a result, Britain was better (although not perfectly) prepared for the Second World War. And large parts of Europe seem further away from readiness now, so the lessons are vitally important.

Joining us to discuss these lessons is Professor Sir Hew Strachan from the University of St Andrews. Described by Jonathan Boff as 'the most influential British historian of the First World War of his generation', Professor Strachan has published widely on the First World War and is a regular advisor to the British Government and Ministry of Defence, particularly in relation to reserve forces and veterans.

Professor Michael Epkenhans describes how Otto von Bismarck's adroit use of war, realpolitik and the harnessing all levers of state power unified the German nation.

Otto von Bismarck, Prussian Chancellor and – after 1871 – the leading political figure of the Second German Empire after the Kaiser, hated to be bullied but managed to manipulate and bully all around him into following his complex strategic plan. This involved not only keeping German democrats at bay but also Denmark, Austria, and France. Tricking Denmark and France into breaking conventions and declaring war on Prussia and its allies respectively, he got the other German states to close ranks and back the Prussian claim for leadership in a newly united German State.

By putting Prussia on the defensive, the other European great powers – the United Kingdom and Russia – did not intervene, even though the emergent German superstate changed the balance of powers in Europe. Stopping short of aiming for overseas territories, taking on the role of the honest broker of the quarrels among others, Bismarck avoided pushing Britain and Russia over the brink into coalescing against Germany – which his immoderate successors did not.

We are joined by Michael Epkenhans, Beatrice Heuser's successor as Director of Research at the Bundeswehr's Military History Research Office, and specialist on 19th century German and Prussian history.

Innovation has long been a Western strategy, but how can it be made effective against an industrially and economically strong China? Dame Fiona Murray explains.

A defining feature of the West's Cold War approach to the Soviet Union was leveraging its technological and economic advantages, including through 'offset strategies'. While defence innovation remains a pillar of Western security, its focus has shifted toward dual-use technologies, reflecting a broader move of the locus of innovation from states to private industry.

However, just as earlier episodes in Season 5 explored (Episodes 10 and 11 regarding US industrial mobilisation during the Second World War, and Jean Monnet's plans for European post-war cooperation), success requires many actors coming together to create a resilient ecosystem. Achieving this demands alignment by all parties.

Professor Dame Fiona Murray is the Chair of the NATO Innovation Fund and William Porter (1967) Professor of Entrepreneurship at the Massachusetts Institute of Technology. She advises the UK Government and sits on the European Innovation Council Joint Expert Group. Her work is published widely in Science, Nature, American Journal of Sociology, Organisation Science and the Journal of Economic Behaviour and Organisation. Her most recent book Accelerating Innovation: Competitive Advantage through Ecosystem Engagement, (MIT Press, 2025) is with Phil Budden.
