This article conducts a comparative analysis of naval shipbuilding approaches by Australia, Britain, and Canada with a view to promoting wider understanding of naval shipbuilding in Canada. Through various strategic and tactical factors, it illuminates how Canadians got to where they are in naval shipbuilding, which processes should be kept, and where there are shortfalls. With a focus on large naval ships, defined as 1000 tons or heavier, the article finds that much of Canada's naval shipbuilding strategy makes sense and should be continued. Yet there are critical problem areas that, if not addressed, threaten to leave the Royal Canadian Navy without the warships it needs.

The digitalization of shipbuilding processes has become an important trend in modern naval construction, enabling more efficient design, assembly, and maintenance operations. A key aspect of this digital transformation is traceability, which ensures that every component and step in the shipbuilding process can be accurately tracked and managed. Traceability is critical for quality assurance, safety, and operational efficiency, especially when it comes to identifying and addressing defects that may arise during construction.

Aiming at the control challenges faced by unmanned surface vessels (USVs) in complex environments, such as nonlinearities, parameter uncertainties, and environmental perturbations, we propose a non-singular terminal integral sliding mode control strategy based on an extended state observer (ESO). The strategy first employs a third-order linear extended state observer to estimate the total disturbances of the USV system, encompassing both external disturbances and internal nonlinearities. Subsequently, a backstepping sliding mode controller based on the Lyapunov theory is designed to generate the steering torque control commands for the USV.

Seaborn trade has a share of about 80 % in global supply chains and is responsible for approximately 10 % of global carbon emissions. This is why the environmental impact of ships and the shipbuilding process matter. Despite that, this topic is addressed rather sparsely in the present literature body.

Within the range of composite laminates for structural applications, sandwich laminates are a special category intended for applications characterized by high flexural stresses. As it is well known from the technical literature, structural sandwich laminates have a simple configuration consisting of two skins of very strong material, to which the flexural strength is delegated, between which an inner layer (core) of light material with sufficient shear strength is interposed. As an example, a sandwich configuration widely used in civil, naval, and mechanical engineering is that obtained with fiberglass skins and a core of various materials, such as polyurethane foam or another lightweight material, depending on the application.
