May delivered another strong month across the defense technology sector, with readers closely following developments in autonomous logistics, integrated soldier systems, advanced propulsion, and resilient communications technologies.

Integrated soldier modernization and unmanned operational capability were key areas of focus throughout the month. Galvion unveiled its CORTEX EVO™ platform at SOF Week 2026, while Sikorsky and Robinson Unmanned secured a U.S. Marine Corps contract for the R66 TURBINETRUCK cargo helicopter platform.

Autonomy remained a clear theme across several of the month’s leading stories. DTC launched a tracking antenna designed to maintain continuous UAV data links without operator intervention, while Rotron Aerospace validated the propulsion and long-range performance of its SkyLance strike platform.

Elsewhere, Sagetech Avionics secured a major U.S. Army production contract for advanced IFF transponders, reflecting continued investment in battlefield identification and survivability technologies.

Together, these stories offer a snapshot of the technologies shaping next-generation defense operations, spanning logistics, connectivity, strike capability, and integrated soldier systems.


Galvion Unveils CORTEX EVO™ to Advance Integrated Head & Data Systems

Galvion has launched its CORTEX EVO™ system at SOF Week 2026, marking a significant shift in how power and data management are integrated into headborne soldier systems.

Building on the architecture first introduced in 2025, the EVO system embeds power distribution and processing capabilities directly within the helmet structure itself. Read more >>


Sikorsky & Robinson Unmanned Secure USMC Contract for Autonomous Cargo Helicopter

Sikorsky & Robinson Unmanned Secure USMC Contract for Autonomous Cargo Helicopter

The United States Marine Corps has awarded a $15.5 million contract to Sikorsky for the Medium Aerial Resupply Vehicle – Expeditionary Logistics (MARV-EL) Increment 2 program.

This initiative centers on the R66 TURBINETRUCK, an autonomous cargo helicopter developed through a collaboration between Sikorsky and Robinson Unmanned. The platform integrates Sikorsky’s MATRIX autonomy system with the Robinson Helicopter Company R66 airframe to provide flexible and rapid combat sustainment. Read more >>


DTC Launches Autonomous Tracking Antenna For UAV Operations & Extended Connectivity

The BluTrak-90-D Autonomous Tracking Antenna has been launched by DTC, a Codan Company, to maintain real-time data links with unmanned aerial vehicles without requiring operator intervention.

Unlike traditional fixed antennas that demand manual alignment and can struggle to maintain connectivity as the drone moves, the BluTrak-90-D autonomously tracks UAV movement. At the core of the system is an onboard microprocessor running embedded tracking algorithms, which continuously follows the movement of the drone. Read more >>


Rotron Validates Advanced Propulsion & Long-Range Capability in Successful SkyLance Firing

Rotron Validates Advanced Propulsion & Long-Range Capability in Successful SkyLance Firing

Rotron Aerospace has demonstrated and fired its SkyLance long-range one-way effector platform, validating the propulsion and system performance of the UK-developed autonomous strike system.

The milestone follows the recent acquisition of the UK-based developer by Ondas Inc., a move intended to accelerate investment and scaling of British operations. The SkyLance platform is designed to deliver precision payloads over extended distances in contested environments, utilizing proprietary propulsion technology that offers improved range, endurance, and efficiency compared to traditional turbine or piston-engine systems.
