U.S. Shifts MGUE GPS Upgrade to Gray Eagle Drones Amid B-2 Delays

Securing Military Navigation: The MGUE Shift from B-2 to Gray Eagle
In modern warfare, secure positioning and navigation systems are mission-critical assets. The U.S. military’s $6.8 billion Military GPS User Equipment (MGUE) program represents a pivotal upgrade to counter emerging electronic warfare threats. At its core lies the M-Code signal – a hardened GPS technology designed to resist jamming and spoofing attacks that could disable conventional systems.
Recent developments have reshaped this two-decade modernization effort. In late 2024, Space Force leaders made a strategic pivot, switching MGUE Increment 1’s lead aviation platform from the B-2 Spirit stealth bomber to the Army’s MQ-1C Gray Eagle drone. This decision underscores both the program’s technical complexities and the urgency to field next-gen navigation capabilities across diverse military assets.
The MGUE Imperative: Modernizing Military Navigation
First conceived in the late 1990s, MGUE addresses a critical vulnerability – traditional GPS signals’ susceptibility to disruption. The program’s centerpiece is the M-Code signal, offering 100x greater anti-jamming protection through advanced cryptography and signal structure. Over 500 military platforms across all service branches require upgrades to utilize this capability.
Increment 1 focuses on developing Application-Specific Integrated Circuit (ASIC) cards for four key platforms. While ground and maritime systems progressed relatively smoothly, aviation integration proved particularly challenging. The B-2 bomber’s complex stealth systems created unique integration hurdles, contributing to a 3-year delay in aviation card certification.
“We’ve got to finish that program,” stressed Cordell DeLaPena, Space Systems Command’s PNT lead. “M-Code isn’t optional – it’s our shield against near-peer electronic warfare capabilities.”
Platform Shift: Strategic and Logistical Drivers
The decision to substitute Gray Eagle for the B-2 reflects practical testing realities. With only 20 B-2s operational, availability for extensive flight testing became problematic. General Atomics’ Gray Eagle offered more flexible test opportunities, with 12 active drones and lower operational constraints compared to strategic bombers.
This shift accelerates fielding timelines – Gray Eagle testing began Q1 2025 versus the B-2’s planned Q4 2024 start. Army Program Executive Office Aviation confirms the drone’s card-level certification remains on track for summer 2025, with full platform integration expected by 2026.
Broader Implications for Military Modernization
The platform change highlights a growing DoD emphasis on unmanned systems as technology testbeds. Gray Eagle’s 27-hour endurance allows extended M-Code stress testing under varied conditions – a capability difficult to replicate with crewed aircraft. Successful integration here could streamline future UAV/UGV upgrades.
However, challenges persist. The Army and Marine Corps have already abandoned MGUE cards for ground vehicles, opting instead for commercial M-Code solutions. This bifurcated approach risks creating capability gaps until Increment 2’s multi-domain solutions mature in the 2030s.
Navigating Future Challenges
With $214 million allocated in FY2025, MGUE’s success now hinges on parallel progress in space and ground segments. The delayed Next-Gen Operational Control System (OCX) finally enters operator testing this fall, a critical enabler for full M-Code functionality. Program leaders emphasize that 85% of MGUE’s technical risks have been retired, but schedule pressures remain intense.
Looking ahead, MGUE’s lessons are informing the Pentagon’s $12 billion PNT modernization strategy. As Lt. Gen. Philip Garrant notes, “This isn’t just about new hardware – it’s about building an architecture resilient enough for multi-domain operations against advanced adversaries.”

NHIndustries has commenced the flight test and qualification campaign for the NH90 Software Release 3 configuration following the upgraded helicopters maiden flight in Italy on July 21, 2026. In a press release issued on August 3, 2026, the manufacturer confirmed the successful flight of the standard, also known as Block 1, which introduces the world’s first airborne Link 22 tactical data link integrated onto a helicopter.
Technical enhancements in the Block 1 configuration
The Software Release 3 (SWR3) upgrade represents a substantial capability enhancement for the NH90 program. The integration of the Link 22 tactical data link allows for secure, beyond-line-of-sight communications without relying on satellite infrastructure. This capability is designed to improve interoperability among allied military forces in contested electromagnetic environments.
Alongside the data link, the SWR3 configuration includes several sensor and system upgrades. The aircraft features the LEOSS-T Electro-Optical Observation System, as well as the OTS-90 Mark II and FLASH sonars for anti-submarine warfare applications.
The July 21 maiden flight was conducted using an SH90, the Italian Navy (Marina Militare) designation for the Nato Frigate Helicopter (NFH) variant. NHIndustries described the event as a major milestone in the evolution of the NH90 program.
“Software Release 3 represents one of the most significant capability upgrades introduced to the NH90 in recent years,” the company stated.
Development timeline and fleet integration
The first flight occurred just over two years after the initial development agreement was finalized. On June 13, 2024, NHIndustries and the NATO Helicopter Management Agency (NAHEMA) signed a contract valued at more than €600 million to develop and deliver the SWR3 standard.
New production aircraft are already slated to receive the Block 1 upgrades directly from the assembly line. On December 9, 2025, the Royal Netherlands Air and Space Force signed a contract for three additional NH90 NFH helicopters. Leonardo will assemble these airframes in Italy, and they will be delivered with the SWR3 features embedded.

Lockheed Martin AI Flies 27 Live Intercepts on X-62 VISTA
Skunk Works AI executed 27 autonomous intercepts using live infrared sensor feeds on the X-62 VISTA at Edwards AFB.

On August 4, 2026, Lockheed Martin Skunk Works and the U.S. Air Force Test Pilot School announced the successful demonstration of sensor-driven AI autonomy on a fighter aircraft at Edwards Air Force Base in California. The test series transitioned airborne AI from simulated environments to real-time, on-board sensor streams, validating the technology’s ability to execute combat-critical maneuvers against a live target.
In a press release issued by Lockheed Martin Corporation, the company detailed how its AI agents utilized live targeting data from an operational sensor to autonomously pilot the X-62 Variable In-flight Simulation Test Aircraft (VISTA). The AI successfully maneuvered the aircraft into tactical intercept positions against a live T-38 target aircraft, marking a critical step toward the U.S. military’s objective of AI-augmented air dominance.
Live sensor integration and flight testing
The Test-Flights campaign consisted of eight flights, during which the AI system executed 27 autonomous air intercepts against the T-38. The integration of the AI agents with the X-62 VISTA, including comprehensive ground testing, was completed in a three-month timeframe.
The system relied on the Lockheed Martin Legion Pod, which provided classified infrared search and track feeds directly to the autonomous agents. This allowed the AI, generated through Lockheed Martin’s “Supermassive” capability, to process real-world data and command the aircraft in real time without relying on pre-programmed simulation parameters.
“Our autonomous agents consumed classified infrared search and track feeds and executed combat-critical maneuvers in real time. This achievement marks a decisive advance toward delivering AI-augmented air dominance for the United States,” said Ron Fehlen, Vice President and General Manager of Lockheed Martin Skunk Works.
Closing the sensor-to-action loop
The collaboration between Skunk Works and the U.S. Air Force Test Pilot School (TPS) has utilized the X-62 VISTA as a foundational testbed for autonomy programs over the past three years. The recent tests demonstrate the ability of artificial intelligence to reliably close the sensor-to-action loop aboard an operational combat aircraft.
Stacy Kubicek, Vice President and General Manager of Lockheed Martin Sensors and Global Sustainment, emphasized the importance of seamless data integration between hardware sensors and software agents.
“Our ability to provide reliable sensor data is critical, but the real advantage comes when that data can connect seamlessly with AI to take action. This project demonstrates how sensing and autonomous AI can come together as a force multiplier to make faster, more informed action in complex environments,” Kubicek stated.
Future upgrades and network integration
Following the successful intercept demonstrations, Lockheed Martin outlined plans to implement a Mission Systems Upgrade for the X-62 VISTA. This planned enhancement is designed to enable broader integration of combat systems, sensors, and airborne AI agents within a next-generation mesh network.
AirPro News analysis
We view the transition from simulated data to live, classified infrared search and track feeds as a major threshold in military aviation autonomy. While previous X-62 VISTA flights proved that AI could safely fly a fighter aircraft using pre-programmed or simulated parameters, injecting live sensor data introduces the unpredictability of real-world combat environments. The rapid three-month integration timeline also suggests that the underlying software architecture is maturing to a point where new capabilities can be fielded at a pace closer to commercial software development than traditional aerospace procurement cycles. The upcoming Mission Systems Upgrade will likely serve as a critical proving ground for the collaborative combat aircraft (CCA) concepts currently under development by the U.S. Air Force.
