Collins Aerospace Radar Production Expansion Strengthens US GaN Defense Electronics

Collins Aerospace

Collins Aerospace radar production is set to expand in Largo, Florida, as the aerospace and defense supplier invests in higher output for commercial aviation radar and multi-domain security solutions. The company plans to spend $26.5mn on the facility expansion.

Collins Aerospace radar production growth follows a $438mn contract awarded by the Federal Aviation Administration in January. The contract supports the FAA’s radar system replacement programme and gives Collins a major role in modernising US aviation surveillance infrastructure.

Collins Aerospace radar production will include Condor Mk3 and ASR-XM radar systems. These products use gallium nitride technology, making the expansion strategically relevant to compound semiconductors, defense electronics and high-performance radar supply chains.

The Largo facility already produces radars, satellite components and secure communications components. Full expansion operations are expected to begin by late 2026.

GaN Technology Raises Radar Performance and Materials Importance

Gallium nitride is becoming more important in radar and power electronics because it can outperform conventional silicon and gallium arsenide in demanding applications. GaN supports higher efficiency, higher voltage operation, faster switching and stronger high-temperature performance.

These characteristics are critical for aviation radar. Modern radar systems need higher power density, reliability and precision while operating in harsh conditions.

The Condor Mk3 and ASR-XM programmes therefore represent more than an equipment upgrade. They show how advanced semiconductor materials are becoming central to aerospace and defense capability.

GaN-based radar systems also strengthen the strategic value of compound semiconductor supply chains. As defense, aviation, satellite and communications systems become more electronics-intensive, access to qualified GaN materials and manufacturing capacity becomes a national security issue.

For Collins Aerospace, expanding Largo’s production capability improves its ability to support both civil aviation infrastructure and broader security markets.

FAA Radar Replacement Supports Domestic Manufacturing Capacity

The FAA radar replacement programme gives Collins a clear demand anchor for the Largo expansion. Long-term government contracts can support capital investment, workforce planning and equipment upgrades.

This matters because aerospace and defense electronics require qualified production environments, secure supply chains and strict reliability standards. Capacity cannot be added quickly without investment in specialised facilities and skilled labour.

The Largo site’s existing radar, satellite and secure communications work gives Collins an established base for expansion. The new investment should deepen that capability while supporting US domestic manufacturing.

The project also fits the broader reshoring trend in advanced electronics. Governments and major contractors are prioritising local production for systems tied to aviation safety, national defense and critical infrastructure.

For materials suppliers, the key signal is demand growth for GaN-related inputs and processing capability. Radar, satellite communications, power electronics and secure systems are likely to remain important demand channels for compound semiconductor materials.

The Metalnomist Commentary

Collins Aerospace’s expansion shows that GaN is moving deeper into critical aviation and defense infrastructure. The strategic bottleneck will not only be radar assembly, but reliable access to qualified compound semiconductor materials and manufacturing capacity.
