Manual wargaming is emerging as a powerful tool for evaluating novel maritime concepts when time, data and funding are limited. By exploring system-of-systems interactions early, it helps shape requirements, assess autonomous applications, and inform future force design decisions, offering a practical bridge to more rigorous operational analysis and capability development.

Large Uncrewed Surface Vessels could transform naval operations, but mission success depends on a careful balance of survivability, resilience and risk. Combining vulnerability analysis, wargaming and engagement modelling, emerging approaches examine how platform-level protection and force-level design can enhance endurance, reduce losses and strengthen operational effectiveness in contested environments.

Human performance is becoming a critical design factor in advanced maritime systems. By combining digital crew-modelling tools, at-sea data collection and psychophysiological monitoring, emerging approaches enable evidence-based crewing decisions, helping predict fatigue, stress and workload while improving safety, operational effectiveness and workforce resilience across increasingly complex naval platforms.

Hybrid and electric propulsion is gaining momentum in naval shipbuilding, offering measurable gains in endurance, efficiency and sustainability. Drawing on Indian industry expertise, emerging solutions for smaller naval vessels demonstrate reduced emissions, lower lifecycle costs and greater operational flexibility, positioning advanced propulsion technologies as a strategic opportunity for future fleet modernisation.

Integrating operational simulation into early-stage vessel design is helping naval architects link design choices directly to mission outcomes. Using naval operations modelling and USV case studies, this approach provides earlier insight into capability, effectiveness and performance, enabling more informed decisions and better alignment between vessel design and operational requirements.

Multi-attribute decision-making could help transform naval ship design by adapting proven platforms to evolving mission demands. Applying structured evaluation methods to warship development offers a faster, more cost-effective alternative to wholly new designs, balancing performance, survivability and operational flexibility while addressing the growing complexity of modern multi-role naval operations.

Energy efficiency is emerging as a strategic priority in future warship design. Combining hydrodynamic innovation, hybrid propulsion analysis and voyage-scale energy modelling, new research demonstrates pathways to reduce power demand, lower through-life costs and improve operational resilience, laying the groundwork for more sustainable and mission-effective naval platforms.

Modularity can enhance flexibility in future naval vessels, but its value depends on the application. Combining Modular Function Deployment, Analytical Hierarchy Process and Knowledge-Based Engineering, a structured assessment framework reveals where modular designs improve effectiveness and where conventional solutions remain preferable, offering sharper insight for early-stage design decisions.

Digital transformation is reshaping naval sustainment through shipbuilding-specific lifecycle management, digital twins and model-based maintenance. By creating a connected digital thread across design, production and in-service support, emerging approaches reduce lifecycle costs, improve fleet availability and accelerate maintenance planning, helping navies enhance readiness for evolving operational demands.

Advanced waste heat recovery and energy storage technologies are set to redefine power efficiency in future defence platforms. By identifying high-impact, operationally viable solutions and modelling integrated power plant architectures, researchers demonstrate potential efficiency gains of up to 20%, supporting sustainability goals, reducing energy losses and strengthening long-term operational effectiveness.

As autonomous military systems evolve, understanding risk to human life is becoming more complex than simply removing people from hazardous environments. This perspective examines emerging challenges in human-machine interaction, command authority and learning systems, exploring how military organisations can identify, assess and manage life-critical risks in future defence technologies.

Digital technologies are accelerating the maritime sector’s transformation toward smarter, cleaner and more autonomous operations. By combining digital twins, advanced simulation, lifecycle management and AI-driven predictive analytics, organisations can optimise performance, meet sustainability goals and enhance safety, revealing new opportunities for the next generation of intelligent maritime capabilities.
