From concept to reality

MST utilises state of the art Solidworks™ 3-dimensional computer aided engineering software to develop our craft and their components.

To greatly increase the likelihood of your operational success we apply the six principles of relative superiority to craft design: simplicity, security, repetition, surprise, speed and purpose.

Each aspect of every craft is fully modelled, including its material properties, allowing MST to calculate extremely accurate weight predictions and successfully engineer complex lifting systems for precise dynamic behaviour. A further benefit of this approach is that clients can accurately visualise their proposed craft and take an active role in vessel development.

MST’s team of naval architects is experienced in a wide range of disciplines from hull design to prototype testing and classification society compliance. MST carries out finite element analysis of structures in-house to ensure features such as lift systems and towing are safe for their intended purpose. In addition, structures are optimised as part of weight-saving disciplines and as part of a company-wide efficient engineering ethos, with all design work controlled through our accredited QA system.

In-house electrical engineering design and development secures MST’s position at the forefront of electrical systems for military and professional vessels, focusing on system reliability, redundancy and maintainability, always adhering to relevant international standards.


Working with technology

Systems integration is one of the most critical aspects of a project for global defence and security markets and MST has a proven track record of integrating complex systems and sub-systems into our marine craft to deliver unique capability to the end user.

We actively engage with specialist subcontractors to develop ground-breaking technology to ensure that operators of MST craft have the technical advantage.

Sophisticated electro-optical thermal and infrared cameras, C4ISR and WAIS systems and cybersecurity are all now commonplace and we understand the need to deliver craft that not only meet current requirements but also look to near-future capability to ensure effectiveness and operability throughout the craft’s entire service life.



All aspects of MST craft are manufactured by experts using only the best materials and highest engineering skills. Our model of experts working with experts ensures your craft is manufactured to the exact high standards both you and MST set and rightly expect. Dedicated MST project managers work closely with clients and our production team to ensure complete product satisfaction and timely delivery.
