Persistent, agile solutions capable of operating seamlessly across open-ocean and littoral environments is an operational requirement for navies across the globe. We have an extensive pedigree in delivering agile, modern naval technology able to react in seconds, to ensure proportionate, effective responses in today’s maritime battlespace.

At CNE 2026, we’ll be showcasing our state-of-the-art applications for naval ship and fleet protection, and undersea surveillance systems.

Our countermeasure system, Ancilia, as selected by the UK Royal Navy for the Ministry of Defence’s Electronic Warfare Countermeasures Increment 1a programme represents a new era of adaptive naval defence, delivering agile, resilient countermeasures for complex, multi-threat environments. It provides real-time intelligent assessment, rapid response against surface, subsurface and air threats, and modular integration across new and existing platforms, where every second counts in combat.

In the Undersea Battlespace, our small form-factor towed sonar system, KraitSense, delivers persistent, agile protection in even the most challenging environments. Its compact towed sonar design supports crewed, remotely operated and autonomous platforms, offering superior detection range, intelligent acoustic performance and real-time data integration to enhance ASW, ISR and maritime situational awareness.

As global naval challenges continue to evolve, so too must the support solutions underpinning operational success and ensuring platforms and personnel are mission-ready for all circumstances. Our support spans the full spectrum – from installation, commissioning, and tailored training to rapidly deployable In-Service Support Engineering teams.
