The imposition of elevated U.S. trade tariffs in 2025 has exerted a pronounced cumulative impact on defence antenna manufacturing and procurement strategies. Foremost among these measures are tariffs on aluminum and steel, which were increased to 50 percent, translating into a $125 million hit for major contractors this year and an anticipated $500 million drag on earnings in 2025. These raw-material levies have driven up production costs for both structural and RF shielding components, compelling manufacturers to reevaluate supplier agreements and absorb higher input expenses.

Concurrently, the reintroduction of Section 301 tariffs on Chinese-made goods has imposed duties of up to 54 percent on critical electronics and antenna subsystems, further exacerbating cost pressures and complicating global sourcing networks. The cumulative effect extends beyond price inflation: leading defence programs have experienced schedule delays as contractors navigate protracted customs processes and recast value-stream analyses to identify alternative suppliers.

Perhaps most strategically significant has been China’s retaliatory export controls on seven medium and heavy rare earth elements-essential for permanent magnets and advanced RF components-which threaten to disrupt supply chains that are 90 percent reliant on Chinese processing. Facing these interwoven tariff and export restrictions, U.S. stakeholders are accelerating efforts to onshore critical mineral processing and diversify component sourcing through allied partners. As a result, procurement decisions now factor in not only performance and cost but also supply-chain resilience and national security imperatives.

Segmenting the defence antenna market by application reveals a multifaceted ecosystem in which communication functions dominate, spanning line-of-sight, satellite, and troposcatter links for mission-critical data exchange. Within line-of-sight communications, point-to-point and point-to-multipoint topologies underscore the need for scalable connectivity across dispersed force elements. Concurrently, electronic warfare applications-encompassing decoys, direction finding, jamming systems, and signal intelligence-are driving demand for antennas capable of dynamic frequency hopping and adaptive null steering.
