Aerospace and defence leaders face a new test of capability, resilience, and readiness.

Global military expenditure reached a record $2.9 trillion in 2025ⁱ, reflecting growing pressure on defence capability, readiness, and industrial capacity.

Readiness is becoming the defining test. Aerospace, defence, and security leaders must strengthen resilience and agility, improve sustainability and efficiency, and pair advanced technology with the human expertise needed to deploy it effectively. AI, autonomous systems, and new operating domains are raising the standard for how the sector performs.

What’s reshaping aerospace and defence?

The question for leaders is where to modernize capability, where to reimagine risk, and where to build the next source of growth and readiness.

Innovation is reshaping capability.

Across defence, military aerospace, space, and security, organizations are moving beyond legacy systems and traditional business models to build new capabilities, new platforms, and new ways of operating.

Digital and AI are changing how the sector performs.

From situational awareness and program delivery to industrial operations and customer experience, digital and AI capabilities are sharpening decisions, accelerating innovation, and enabling more adaptive operating models.

Risk is becoming a strategic capability.

Threat landscapes, supply chains, regulation, geopolitics, and technological sovereignty are converging into a more complex risk environment, demanding new approaches to resilience and readiness.

From legacy systems to mission-ready capability

Leading organizations are moving beyond legacy systems and traditional business models to build connected, intelligent, and resilient models of performance.

Organizations will be better positioned when they adapt quickly, anticipate disruption, and deliver capability, growth, and security more effectively.
