NATO’s new quantum roadmap schedules sea trials of quantum sensors in 2026 and 2027, initial military pilot assessments in 2027, and a communications pilot between its Brussels and Mons headquarters by year-end 2027. The plan also sets work on quantum-resistant cryptography, shared standards and training; wider military deployment depends on technical progress and trial results.
NATO has published a quantum technology roadmap that schedules military tests and security work through 2027, including sensor sea trials in 2026 and 2027 and a planned secure communications pilot between its headquarters in Brussels and Mons, Belgium, by the end of 2027. The schedule gives the alliance near-term steps for evaluating possible military uses and preparing networks for future quantum-related risks, while leaving broader adoption dependent on trial results and technical progress.
The roadmap calls for the QUESTOR project to test quantum sensing at sea through NATO’s Centre for Maritime Research and Experimentation. The trials are intended to examine positioning, navigation and timing in realistic operating conditions, including settings where global navigation satellite signals are unavailable. These functions help military systems establish location, direction and timing. The schedule places the sea trials in 2026 and 2027; it does not establish that the sensors will meet military requirements or be adopted after testing.
NATO also plans an initial report on military pilot evaluations in the first quarter of 2027, followed by initial comparative assessments in the fourth quarter. The roadmap calls for a first set of assessment criteria in the second quarter of 2027 and an initial repository of relevant military and commercial applications within 12 months. Allied Command Transformation is to coordinate pilot evaluations and work with planners, researchers and NATO’s Transatlantic Quantum Community to identify potential uses.
For communications, NATO plans a pilot connecting its political headquarters in Brussels with its military headquarters in Mons by the end of 2027. The public summary describes this as a pilot, not a completed or alliance-wide system. A separate milestone in the fourth quarter of 2027 is to develop a concept for an allied quantum computing access network. That deadline concerns the network’s design; NATO has not committed to having an operational network by then.
Testing Sensors and Securing NATO Links
The schedule places testing and protection side by side. Quantum technologies may offer new ways to measure movement, position or timing, while sufficiently capable quantum computers could threaten some cryptographic systems used to protect information. NATO’s roadmap addresses both prospects: it sets trials for potential military applications and calls for work to protect communications against future risks.
For allied forces, the sea trials matter because performance in practical conditions can differ from performance in research settings. Testing navigation and timing where satellite signals are unavailable may help NATO assess whether quantum sensors could support existing capabilities. The roadmap does not report trial results or establish that the technology is ready for field use. The assessments are meant to inform later decisions about which applications warrant further work.
The Brussels–Mons pilot would give NATO a defined setting to examine quantum-resilient communications. It is one project within a broader security effort that includes implementing post-quantum cryptography standards on conventional systems. These measures are relevant before a practical quantum computer can break current protections: organizations need time to assess suppliers, select suitable standards and plan changes to networks and equipment. The roadmap identifies that preparatory work, but the public summary does not specify the systems or data the pilot will cover.
From Strategy to Scheduled Trials
The roadmap puts timelines behind NATO’s quantum strategy adopted in November 2023. The alliance’s public summary says the aim is to move promising applications from research toward military use while protecting networks, infrastructure and operations from risks associated with the technology. NATO frames the work as part of strategic competition, saying potential adversaries and competitors are investing heavily in quantum research.
The plan covers five areas: military applications, testing and adoption, common standards, protection against threats, and training. It includes regular prototyping and testing through NATO initiatives such as the Digital Foundry and the Defence Innovation Accelerator for the North Atlantic, known as DIANA. NATO Innovation Ranges are also identified as a possible testing route. The roadmap calls for annual assessments of emerging technologies and periodic updates to its application repository, with applications assessed for strategic importance, technical feasibility, timing and possible integration into existing capabilities.
Post-quantum cryptography is a separate but related strand. It uses mathematical methods designed to resist attacks from quantum computers and can be implemented on conventional computing systems. NATO lists standards work as ongoing. An industry-readiness study by the NATO Industrial Advisory Group is due in the second quarter of 2027, and the next update to the alliance’s action plan on the quantum threat to cryptography is scheduled for the third quarter.
Adoption Depends on Trial Results
The public summary does not set a fixed date for broader military deployment. NATO says quantum computing, communications and sensing are developing at different speeds, and later stages depend on technical progress and the results of initial experiments. The roadmap therefore provides milestones for testing and assessment, rather than a commitment that particular systems will enter service on a set schedule.
Details about the planned communications pilot remain limited in the available summary. It does not specify which cryptographic standards, equipment, data or operational functions will be included, how the pilot’s performance will be measured, or when results will be released. The source also does not provide trial findings for QUESTOR or name particular sensor systems. The milestones describe planned activities, not evidence that the tests have already taken place.
Milestones Through Late 2027
NATO’s next listed steps include the 2026–2027 QUESTOR sea trials and a first military pilot evaluation report in the first quarter of 2027. Initial assessment criteria are due in the second quarter, alongside the industrial-readiness study on quantum-resistant cryptography. The alliance’s cryptography action plan is scheduled for an update in the third quarter.
In the fourth quarter of 2027, NATO expects initial comparative assessments of military pilots and a concept for an allied quantum computing access network. The communications pilot linking Brussels and Mons is planned by year-end. Whether those activities lead to further trials, procurement or operational use will depend on what the evaluations show and on the pace of technical development.
Key Questions
What has NATO announced?
NATO has published a roadmap setting milestones for evaluating quantum technologies in military settings and preparing alliance communications for potential quantum threats. The schedule includes sensor trials, pilot assessments, cryptography work and training.
When will NATO test quantum sensors?
The roadmap schedules QUESTOR sea trials for 2026 and 2027. They are intended to test positioning, navigation and timing performance in realistic maritime conditions, including where satellite navigation signals are unavailable.
Will NATO have a quantum communications network by 2027?
The roadmap plans a communications pilot between NATO headquarters in Brussels and Mons by the end of 2027. A separate quantum computing access network milestone is for a design concept in the fourth quarter of 2027, not an operational network.
What does post-quantum cryptography mean?
It refers to mathematical methods designed to resist attacks from quantum computers. NATO lists standards implementation as ongoing and has scheduled an industry-readiness study for the second quarter of 2027.
Has NATO set a date for wider military deployment?
No fixed deployment date appears in the public summary. NATO says later stages will depend on technical progress and the results of initial experiments.
