Lockheed Martin is advancing resilient Position, Navigation and Timing (PNT) capabilities by integrating its modernized GPS satellite technology with next-generation quantum navigation sensors. The defense contractor detailed the strategic integration in a feature published on June 24, 2026, highlighting a system designed to ensure unbroken positioning for military operators in contested or GPS-denied environments.

Traditional GPS signals can be disrupted by physical structures, severe space weather, or adversarial jamming. To counter these vulnerabilities, Lockheed Martin is pairing satellite data with quantum sensors that operate independently of external signals by relying entirely on internal measurements. This combination allows the GPS network to establish a reliable baseline while quantum technology continuously refines the positioning data.

Modernizing the GPS constellation

The foundation of this hybrid navigation approach relies on the ongoing modernization of the United States military satellite network. Lockheed Martin produces the GPS III and upcoming GPS IIIF satellites, which introduce significant upgrades over legacy spacecraft to maintain signal integrity in hostile electronic environments.

According to the company, GPS III satellites deliver up to eight times the anti-jamming power of previous generations. The subsequent GPS IIIF satellites will increase this anti-jamming capability up to 63 times through Regional Military Protection (RMP) beam-focusing techniques. Beyond military applications, these modernized satellites incorporate specialized emergency signal processing for Civilian Search & Rescue operations and a Nuclear Detection System to monitor global treaty compliance.

Transitioning quantum technology to the field

To complement the satellite network, Lockheed Martin is accelerating the deployment of quantum technology from laboratory environments to operational hardware. This effort is supported by multiple United States Department of Defense (DoD) initiatives aimed at fielding functional prototypes.

On March 12, 2025, the Defense Innovation Unit (DIU) awarded a contract to Lockheed Martin, alongside quantum technology companies Q-CTRL and AOSense, to prototype a Quantum-enabled Inertial Navigation System (QuINS). The QuINS platform utilizes matter-wave interferometry to calculate a vehicle’s position, speed, and orientation based entirely on internal measurements, rendering it immune to external signal jamming.

Development continued when Q-CTRL announced its selection for the Defense Advanced Research Projects Agency (DARPA) Robust Quantum Sensors (RoQS) program on August 27, 2025, with Lockheed Martin serving as a subcontractor. At the 2026 Joint Navigation Conference, the partner companies presented technical progress on Phase 1 of the QuINS program, which involves testing a purpose-built sensor equipped with a laser and electronics package optimized for dynamic environments.

Lockheed Martin emphasized the necessity of this dual approach in its June 24 publication.

“GPS determines the initial ‘big picture’ position, providing the range of known locations with civilian global Earth coverage. Quantum sensing refines that picture, delivering pinpoint accuracy in conjunction with GPS signals, even in contested environments.”

The integration of quantum inertial navigation with modernized GPS represents a critical shift in aerospace engineering, particularly for military aviation and unmanned aerial systems operating in contested airspace. As electronic warfare and GPS spoofing become standard adversarial tactics, reliance on external radio frequency signals is a known vulnerability. By moving quantum sensors out of the laboratory and into dynamic flight environments, we are observing the foundational steps toward fully autonomous, unjammable navigation systems. While the current focus remains on defense applications, the successful miniaturization and ruggedization of matter-wave interferometry packages will likely influence future commercial aviation navigation standards.

Lockheed Martin Corporation has introduced the Next Generation Glide Body (NXGB), a new hypersonic weapon system designed to drastically reduce unit costs and increase production volume for the U.S. military. The aerospace manufacturers announced the program on June 24, 2026, targeting a preliminary flight demonstration in 2027.

The announcement, detailed in a company press release, represents a strategic pivot toward a manufacturing-first approach in hypersonic development. This shift directly addresses recent U.S. Army budget realignments that prioritize affordable, scalable long-range strike capabilities over legacy, high-cost hypersonic programs.

Shifting away from legacy hypersonic costs

The development of the NXGB follows a significant change in U.S. Army procurement strategy. According to reporting by Aviation Week, the Army revealed plans in April 2026 to move away from future purchases of Lockheed Martin’s Long Range Hypersonic Weapon (LRHW). The legacy LRHW program faced criticism for its high flyaway unit cost, estimated between $35 million and $40 million, and a maximum annual production rate limited to 24 missiles.

In response to these constraints, the Army eliminated funding for the LRHW after fiscal 2027. The service branch established a new target, seeking a hypersonic alternative priced at less than $1.5 million per unit by fiscal 2029. Lockheed Martin positioned the NXGB as the direct answer to this demand for affordability and high-volume manufacturing.

Johnathon Caldwell, Vice President and General Manager of Strategic and Missile Defense Systems at Lockheed Martin, stated in the press release that the new system demonstrates a commitment to delivering deterrence that is “not only effective, but affordable and producible at scale.”

Design changes and manufacturing infrastructure

To achieve the required cost reductions and performance metrics, the NXGB incorporates distinct aerodynamic and structural changes compared to its predecessor. Aviation Week notes that the new glide body features a wedge-shaped design. This configuration likely provides a higher lift-to-drag ratio than the conical shape utilized by the older Common Hypersonic Glide Body (CHGB).

Lockheed Martin confirmed the NXGB has successfully completed its Preliminary Design Review. The company is leveraging its existing manufacturing infrastructure in North America, specifically facilities in Huntsville and Courtland, to support the rapid scaling of production.

“NXGB reflects a paradigm shift focusing on design for manufacturing at scale while implementing decades of lessons learned designing, producing and delivering mission-critical systems for the warfighter,” Caldwell said.

We view the NXGB announcement as a necessary course correction for the U.S. defense industrial base regarding hypersonic weapons. The $35 million to $40 million unit cost of the LRHW made it financially impractical for the U.S. Department of Defense to stockpile the weapons in quantities required for a sustained conflict. By targeting a sub-$1.5 million price point, the Army is forcing prime contractors to prioritize modularity and open systems architecture over bespoke engineering. If Lockheed Martin can successfully demonstrate the NXGB in 2027 and meet the Army’s fiscal 2029 pricing targets, the company will likely secure a dominant position in the next generation of U.S. hypersonic procurement.

Embraer and Polish aerospace maintenance provider Wojskowe Zakłady Lotnicze Nr 2 S.A. (WZL-2) have signed a Memorandum of Agreement to establish local maintenance and support capabilities for the KC-390 Millennium. The partnership directly supports the Brazilian manufacturer’s ongoing bid to supply Poland’s future multi-role military-aircraft and aerial refueling fleet.

The agreement was finalized on June 25, 2026, at Embraer facilities in São José dos Campos, Brazil. According to the official press release, the framework encompasses a broad range of industrial cooperation, including services and support, aircraft completion and conversion, external painting, and system integration for the KC-390 platform. WZL-2 operates as a key entity within the state-owned Polska Grupa Zbrojeniowa (PGZ) Group.

Strategic positioning in Poland’s transport competition

The Polish Ministry of National Defence is currently evaluating options to replace and expand its transport aviation capabilities. The KC-390 Millennium is competing against platforms such as the Airbus A400M Atlas and the Airbus A330 MRTT. To strengthen its proposal, Embraer has systematically built a network of local industrial partnerships since late 2025.

In December 2025, Embraer signed five initial Memoranda of Understanding with Polish defense companies in Warsaw. This was followed by a formal presentation of the KC-390 Millennium to WZL-2 personnel in Bydgoszcz, Poland, in March 2026. The March event allowed local engineers and technicians to evaluate the aircraft and outline potential maintenance activities, culminating in the formal agreement signed on June 25.

Building a local industrial ecosystem

The collaboration aims to ensure that if Poland selects the KC-390, the domestic defense industry will have the sovereign capability to maintain and support the fleet. WZL-2 President of the Management Board Jakub Gazda stated that the goal is to develop industrial and maintenance capabilities in Poland to support the operation of the aircraft while strengthening the country’s broader aerospace sector.

“We believe that combining Embraer’s experience with WZL No. 2’s capabilities will bring tangible benefits to both the Polish Armed Forces and the entire Polish defense industry,” Gazda said in the company statement.

Douglas Lobo, Vice-President of Customer Support and Aftermarket Sales for Embraer Services and Support, noted that the partnership reinforces the company strategy of fostering local industrial cooperation. Lobo indicated the collaboration will contribute to job creation, skills development, and technology transfer, forming the foundation of a long-term industrial ecosystem in Poland.

KC-390 Millennium capabilities and recent momentum

The Embraer C-390 Millennium features a maximum concentrated payload capacity of 26 tonnes and a maximum cruising speed of 870 km/h. The platform has secured several recent operational and maintenance milestones in the weeks leading up to the Polish agreement.

On June 18, 2026, Embraer signed a comprehensive service and support agreement to enhance the operational availability of the Brazilian Air Force KC-390 fleet. Shortly after, on June 23, 2026, Embraer and its Portuguese subsidiary OGMA concluded the first scheduled maintenance on a C-390 Millennium operated by the Hungarian Air Force.

We view Embraer’s formalization of the WZL-2 partnership as a necessary and expected maneuver in the European defense procurement landscape. Sovereign maintenance capability is a baseline requirement for NATO members modernizing their strategic airlift fleets. By locking in a maintenance framework with a primary PGZ subsidiary, Embraer effectively neutralizes one of the primary advantages typically held by European competitors like Airbus. The progression from initial memorandums in late 2025 to a structured industrial agreement demonstrates that Embraer is treating the Polish transport competition as a high-priority campaign.
