The Subsurface Battlespace Just Got Clearer: SitaWare Maritime Launches PMI Planning Capability

The release forms part of the first SitaWare suite update cycle of 2026, which also delivers new AI and interoperability capabilities across the wider product family.

The latest release fully implements Prevention of Mutual Interference (PMI) as commercial off-the-shelf software, allowing commanders to plan and deconflict friendly submarine activity across time, position and depth. The capability provides a clearer shared subsurface operational picture, helping allied forces avoid interference between submarines, ships and underwater sensors during complex multinational operations.

In modern naval operations, friendly submarines often operate in the same contested waters as allied ships, aircraft and other submarines. PMI planning tools help commanders coordinate these movements safely by analyzing potential conflicts in four dimensions and ensuring clear separation between assets before operations begin.

"The addition of PMI planning capabilities takes SitaWare to new depths," said Commander Nicholas Kristof, US Navy (Retired), a former submariner who now serves as Director of Defense Sales at Systematic. "This addition will enable the world's Submarine Operating Authorities to employ SitaWare in their planning processes. Before this update, that just wasn't the case."

Coalition Submarine Operations: From Opacity to Clarity

SitaWare Maritime's latest software release offers submarine planners the ability to ensure safe separation between submarines and other maritime and air assets by analyzing operations across four dimensions: time, latitude, longitude and depth. The capability uses dynamic moving havens that chart a submarine's planned route, providing a shared understanding of where submarines are expected to operate at specific times.

"In multinational operations, clarity and predictability are essential," said Lasse Krabbesmark, Product Manager at Systematic. "PMI ensures that coalition partners can operate together safely whilst maintaining the necessary level of information sharing."

Submarine movement and operations plans can be shared using standard NATO message formats, enabling allied forces to understand when areas are active, when sensors can be deployed, and how to distinguish friendly submarines from potential threats. SitaWare's PMI tool controls and deconflicts these plans prior to dissemination.

As a commercial off-the-shelf solution built on NATO interoperability standards, SitaWare Maritime's PMI capability integrates seamlessly with existing naval command and control systems, enabling rapid deployment across coalition task forces without lengthy integration programmes.

Mine Countermeasures: Unlocking Freedom of Manoeuvre

Building on this foundation of enhanced coalition coordination, Systematic also confirmed that an advanced Mine Countermeasures (MCM) Planning capability will be released later this year. Where PMI ensures submarines can operate safely together, MCM Planning enables coalition forces to clear the path ahead, further strengthening SitaWare Maritime's position as the comprehensive naval command and control solution for multinational operations.

The capability allows mine warfare officers to select available units and define operational areas, after which the system suggests an optimised plan for distributing assets to clear or survey mined waters.

"This is not just about visualisation, it's about collaboration and efficiency," said Krabbesmark. "By proposing a coordinated plan, the system helps coalition forces achieve mine clearance objectives faster and with greater consistency."

The MCM Planning capability supports operations in littoral and contested environments and is designed to scale across national and multinational task groups.

Continuous Innovation Across the SitaWare Suite

SitaWare Maritime is part of the world-leading SitaWare Suite from Systematic, delivering command and control capabilities across land, maritime, and joint domains. With twice-yearly updates, the first release cycle of 2026 demonstrates Systematic's commitment to delivering cutting-edge capabilities that address real operational challenges across the force.

As submarine operations intensify in the Indo-Pacific, North Atlantic, and Baltic Sea regions, and as mine warfare capabilities proliferate in littoral zones from the Persian Gulf to the Arctic, SitaWare Maritime's enhanced capabilities address the immediate coordination challenges facing NATO and allied naval forces operating in these contested environments.

Alongside the Maritime release, SitaWare Insight version 1.9 extends the suite's intelligence and decision support capabilities across all domains, including:

Three new AI capabilities including AI-powered terrain analysis from satellite imagery, AI track prediction based on historical movement patterns, and enhanced Wingman search across uploaded mission documents, giving commanders faster, more actionable intelligence.

NATO imagery interoperability with native support for NATO Secondary Imagery Format (NSIF) in accordance with STANAG 4545, with extracted metadata fully searchable by text, time, and location.

Flexible data modelling through a new Custom Data framework that allows operators to define their own structured data formats and make them searchable without vendor configuration.

Improved platform monitoring and collaboration including a new status dashboard with per-service tracking and alerts, shareable Data Lake URLs, and a new Data Lists application for managing and acting on intelligence holdings.

Expanded automation and AI development with new Robot processors for event monitoring, entity linking, and format conversion, alongside MLFlow support and a data science handbook for users building custom AI models.
