What SeaCross Marine does
SeaCross Marine AB is a Swedish privately held maritime navigation software company founded in 2004 and headquartered in Lidingö, Sweden. It develops the SeaCross Navigation Software Suite — a modular, sensor-agnostic platform of five applications (SX-TAC for tactical/military use, SX-AUTONOMY for unmanned and remote vessel control, SX-NAV for professional high-speed operations, SX-ECDIS for type-approved regulated navigation, and SX-Compact for portable deployment) — sold exclusively to NATO and allied users. The company's technology emphasizes high-speed operations up to 100 knots, GNSS-denied navigation with spoofing/jamming detection, multi-sensor fusion, ultra-low latency, and a unified operator interface spanning manned, remote, and autonomous modes.
The business model is enterprise field sales to government and military customers, with revenue derived from software licensing (subscription/multi-year contracts), hardware sales (ruggedized displays, control units, sensors), and professional services (system design, integration, training, support). SX-ECDIS holds DNV AS type approval and EU MED compliance, and the company maintains ISO 9001:2015 and ISO 14001:2015 certifications. SeaCross has been part of Evallic, a European defense software group, since 2024, and in 2025 released the Software Suite 6000 featuring multi-vessel coordinated autonomous maneuvers. Its customer base consists of navies, special forces, coast guards, and other government maritime authorities across NATO and allied nations.

SeaCross Marine competitors and assessment
Company assessmentDirect peers
- Northrop Grumman Sperry Marine: Global supplier of marine navigation systems (ECDIS, radar, integrated bridge) for commercial and naval fleets. Direct competitor to SeaCross in type-approved naval navigation and integrated bridge systems for defense customers.
- Kongsberg Maritime: Provides integrated navigation, bridge systems, and autonomous vessel control technology for naval and offshore markets. Both a technology partner of SeaCross and a competitor on full-stack naval bridge and autonomy programs.
- OSI Maritime Systems: Specialist in tactical navigation and Integrated Bridge Systems for naval and coast guard customers, including multi-domain awareness for high-speed craft. Closely comparable as a niche, navy-focused navigation software supplier.
- Wärtsilä Voyage: Offers ECDIS, navigation, and ship traffic solutions through its Wärtsilä Voyage (formerly Transas) unit. Direct rival for type-approved ECDIS and integrated navigation software in regulated maritime markets.
- Furuno: Major marine electronics manufacturer supplying radar, ECDIS, and navigation sensors integrated by SeaCross. Competes at the sensor and integrated navigation level for both commercial and defense customers.
- Raytheon Anschütz: Supplies integrated bridge systems, ECDIS, and naval navigation suites for military and commercial vessels. Competes with SeaCross for type-approved navigation procurements, especially in European NATO navies.
Emerging players
- Saildrone: US-based builder and operator of autonomous unmanned surface vessels for defense and science missions. Comparable as an emerging player in maritime autonomy where SeaCross supplies the navigation/control software stack.
Broad incumbents
- Thales (Naval): Global defense prime providing naval combat management, sensors, and integrated bridge suites. Competes for major fleet modernization contracts where SeaCross would be a sub-supplier or specialist partner.
- Saab (Naval domain): Large Swedish defense prime offering combat management, naval systems, and integrated bridge platforms. Listed SeaCross partner but also a broader incumbent competing for end-to-end naval system contracts.
- Leonardo (Naval / Electronics): Italian-headquartered defense prime with naval combat systems, sensors, and integrated electronics. Competes in the same allied-navy procurement environment, particularly across Mediterranean and European NATO fleets.
