THE CHIPS BEHIND GLOBAL SECURITY
Defense and aerospace are being reshaped by technological leadership, from RF, imaging, and sensing technologies to space exploration, satellite communications, and emerging space industries, redefining power, influence, and innovation on a global scale.
The relationship between semiconductors and the defense and aerospace sector has shifted dramatically, driven by escalating trade wars and real conflicts worldwide.
Semiconductors are no longer just components enabling battlefield superiority. The industry itself has become a matter of national security, with nations and alliances pushing for self-sufficiency across the entire supply chain, from devices to key systems.
Today’s defense capabilities rely on a core set of semiconductor-enabled building blocks, including:
Each of these depends on advanced electronic and semiconductor devices, making the chip supply chain a strategic priority at the heart of modern defense and aerospace capability.
The global defense spending environment in 2026 is unlike any seen since the Cold War. The Russia-Ukraine conflict, ongoing tensions in the Middle East, and rising competition in the Asia-Pacific have simultaneously pushed most major defense nations to accelerate procurement. The major powers, the United States, China, and Western Europe, collectively account for more than 60% of global defense spending, and all have expanded their military budgets in 2026 by double-digit growth compared to the previous year. The United States remains the world’s largest defense spender, exceeding $1 trillion in 2026 for the first time.
The military’s operational environment is evolving too, with information and space domains gaining ground over traditional land, sea, and air, driving new semiconductor needs across the electromagnetic spectrum, cyberspace, and information systems.
Hassan Saleh, PhD Principal Technology & Market Analyst, Radio Frequency at Yole Group – “RF technology sits at the heart of every major defense capability, from early-warning radar and fire-control systems to electronic warfare, drone navigation, and counter-drone defenses. When defense budgets expand, RF device suppliers benefit across the board.”
As defense systems push RF performance to its limits, GaN technology has become the enabler, delivering the power density, efficiency, and reliability needed for next-generation radar, jamming, and communication systems.
At Yole Group, we track the technologies powering defense and aerospace, from visible, thermal, and SWIR imaging to RF communications, radar, navigation, and field data processing. We’re also closely watching how sensors and edge computing are reshaping these industries.
By combining this expertise with our deep knowledge of consumer and automotive electronics, we connect the dots across sectors, tracking how innovations and technologies migrate and evolve, to give you a comprehensive view of what’s next.
Silicon still dominates RF technology by volume, thanks to cost and integration advantages. But compound semiconductors, led by GaN, are capturing a growing share of high-power, high-frequency applications where silicon hits its limits.
Ahmad Abbas, PhD, Technology & Market Analyst, Compound Semiconductors at Yole Group – “In today’s geopolitical climate, it is defense demand in particular that is accelerating RF GaN adoption, positioning the sector as the market’s primary growth engine.”
Beyond 2026, RF GaN growth will hinge as much on geopolitical factors including supply-chain sovereignty and export controls, as on technology shifts like energy efficiency, higher frequency bands, and silicon integration.
