UK National Resilience
The United Kingdom's national resilience is a critical pillar of its security in an increasingly volatile global environment. As geopolitical tensions rise, particularly with adversaries such as Russia, the UK faces multifaceted threats that target its centres of gravity: key societal, economic, and infrastructural elements that underpin national stability. These centres include critical national infrastructure (CNI) such as telecommunications, water, energy, and social cohesion, which are vital to the functioning of modern society. In response to these threats, defence primes have advocated for investments in ground-based air defence (GBAD) systems, often citing Israel's Iron Dome as a model for protecting against missile and drone attacks. However, the UK's geopolitical and geographical context differs significantly from Israel, rendering direct comparisons problematic.
While GBAD systems have a role, they are not the primary solution to the UK's immediate threats, which are more likely to involve hybrid warfare, cyberattacks, and disruptions to CNI rather than conventional missile barrages. This essay examines the challenges to UK national resilience, the limitations of GBAD as a solution, recent events targeting UK vulnerabilities, and the broader strategies needed to bolster resilience within the NATO framework.
Understanding Centres of Gravity and UK Vulnerabilities
In military and strategic theory, centres of gravity are the critical capabilities or assets that, if disrupted, significantly weaken a nation's ability to function. For the UK, these include CNI (telecommunications, energy, water, and transport), economic stability, public trust, and social cohesion. Unlike traditional military targets such as bases or airfields, these centres are civilian in nature but essential to national security. Adversaries seeking to undermine the UK are increasingly likely to employ hybrid tactics - combining cyberattacks, disinformation, sabotage, and economic disruption - to destabilise these assets without resorting to direct military confrontation.
Recent events underscore the vulnerability of these centres. In 2024, reports indicated that the UK faces approximately 90,000 cyberattacks daily, many attributed to Russia and its allies, targeting government systems, financial institutions (FSI), and critical national infrastructure (CNI). These attacks aim to disrupt digital infrastructure, steal sensitive data, or sow distrust in institutions. Additionally, suspected sabotage of undersea cables in the Baltic Sea in 2024 highlighted the fragility of the UK's international communications networks, which are critical for economic and security functions. Such incidents demonstrate that adversaries prioritise non-kinetic means to degrade the UK's resilience, exploiting its reliance on interconnected systems.
The UK's population centres are also vulnerable to disruptions that do not involve missiles. Power cuts, for instance, could paralyse urban areas, disrupting healthcare, transport, and food supply chains. The 2019 UK power outages, though not attributed to hostile action, exposed how a single failure in the National Grid could affect millions, with hospitals and transport systems struggling to cope. Similarly, social media-inspired unrest, as seen in the 2011 London riots and more recently in Southport, illustrates how disinformation or orchestrated campaigns could amplify social tensions, undermining public order. These examples highlight that adversaries can achieve strategic goals by targeting civilian infrastructure and societal cohesion rather than military assets.
Defence Primes and the Push for GBAD Systems
Defence primes, such as MBDA and Northrop Grumman, have seized on the growing threat perception to advocate for enhanced air and missile defence systems, particularly GBAD. They point to Israel's Iron Dome, which has successfully intercepted short-range rockets and drones, as a case study for why the UK should invest i...
