Trevor Dove - APAC +61 2 6171 7000 defence-security@bmtglobal.comWe combine deep operational experience, technical expertise, and whole-enterprise insight to deliver effective submarine solutions from concept design through to in-service optimisation. Our approach addresses the most complex engineering, safety, availability, and cost challenges - balancing performance with through-life value.
We work collaboratively with national defence agencies, navies, and prime contractors, bringing all stakeholders together to ensure requirements are defined, risks managed, and designs assured. From hydrodynamics and weight management to safety, supportability, and configuration control, we provide independent, trusted advice and engineering services that keep submarines safe, capable, and resilient in the harshest environments - enabling our customers to make informed decisions and achieve long-term operational success.
Submarines face harsh physical and thermal stresses, alongside regulatory demands. We help manage these through expert design, assurance, and support - delivering safe, capable, and resilient platforms.
Submarine programmes must balance safety, performance, and availability without compromising cost-effectiveness. We help you make informed trade-offs across the lifecycle, managing risk and delivering sustainable mission-ready capability.
Submarine programmes face shifting budgets, approvals, and technical challenges. We provide you with flexible planning and delivery support to keep projects on track as requirements evolve.
A reduction in hull numbers and delays to follow-on classes, in addition to the ever-increasing complexity of systems present a critical threat to availability for nations. We provide Through Life Support to enable pre- and post-delivery logistics.
Our digital twin technology enhances decision-making, operational efficiency, and resilience for defence applications. Leverage real-time monitoring, predictive insights, and virtual testing, enhancing decision-making, operational efficiency, and resilience for defence applications through advanced simulation and data analytics.
BMT RAMtr@ck is an advanced availability planning and maintenance forecasting tool. Whether you’re procuring new assets or optimising existing operations, BMT RAMtr@ck provides the insight needed to maximise asset availability and meet mission demands.
Our award-winning navigation and manoeuvring simulator suite. Engineered for realism and accuracy, it supports mission-critical training, incident reconstruction, and operational planning in high-stakes environments. Discover how BMT REMBRANDT empowers defence professionals to train smarter, operate safer, and lead with confidence.
BMT SEAS delivers independent, simulation-based testing and certification for Maritime Autonomous Surface Ships (MASS). Designed for defence partners, it enables rigorous evaluation in high-fidelity virtual environments—reducing risk, cost, and time to service. Discover how SEAS builds trust in autonomy by aligning innovation with international standards and operational readiness.
At BMT, we’re exploring how AI can enhance submarine design, not by replacing naval architects, but by equipping them with tools that expand their creative and analytical capabilities.
Submarine availability is often spoken about as a downstream problem - something to be solved through better maintenance practices, more skilled support staff, or improved logistics. But I would argue this: availability is fundamentally a design decision.
As global tensions rise and technology evolves at pace, the underwater battlespace is undergoing a profound transformation. In our paper presented at UDT 2025 earlier this year, we explore how submarine operations and undersea warfare are set to change - and what that means for defence stakeholders, policymakers, and technology developers.
BMT, a significant player in the Future Naval Design Partnering (FNDP) Framework, has successfully supported the Royal Navy in advancing its next-generation torpedo capability.
Submarines are designed for a service life of more than 25 years. Therefore, they need to be prepared to meet the needs of tomorrow's and today's needs, which means a flexible operational capability and increased importance on areas such as sustainability and climate resilience in design.
The path to Australia’s nuclear-powered submarine future has many challenges, and while some might underestimate Australia’s ability to make this transition, the challenge and the necessary solutions are doubtlessly receiving the appropriate attention.
Imagine gaining more space, deeper dives, faster refits, and safer missions—all by moving one critical system outside the pressure hull. Discover how pressure-tolerant lithium-sulphur batteries are transforming submarine design, and why this breakthrough isn’t just theoretical—it’s ready for deployment. Whether you're upgrading or designing new, this is capability you can deliver today.
