Who is it for?

The course draws students from the UK and Western Europe, giving an eclectic mix to the classroom environment. Maximum number of places: 25 per year.

The course structure allows students to continue in full-time employment whilst they are studying.

Why this course?

Today’s military aviation platforms are complex systems and it is essential, therefore, that they are deployed and maintained in such a way as to ensure their continued airworthiness and the safety of the crew operating them. Achieving this requires engineers to be cognisant of a broad range of aerospace engineering, airworthiness and safety disciplines.

The MSc distinguishes itself from similar courses offered by leading UK universities by offering one focused specifically on the military context, and offers unique subject areas unavailable elsewhere. You will be taught by staff, primarily from Cranfield Defence and Security and the School of Aerospace, Transport and Manufacturing, many of them world leaders in their field. Visiting lecturers also include experts from industry, research establishments and the MoD.

Course details

The course is delivered on a part-time basis and contains five compulsory modules. Students choose one further module to complete the PgCert or a further seven modules to complete the PgDip (MSc taught phase).

This provides students with the flexibility to tailor their studies to account for prior educational and work experience and the current and future needs of their employment role. The modules taken in the taught phase of the MSc (the PgDip) provide students with the knowledge and skills necessary to complete a research-based project, which forms the final part of the master's award.

Course delivery

A mixture of lectures, laboratory demonstrations, tutorials, essays, examinations, individual and group design exercises and the students are expected to write written assignments. In addition, for MSc students a written dissertation research project and viva voce examination

Individual project

The individual research project will focus on a topical subject area covered by the taught phase of the course. The subject of the project can be chosen to match the research needs of the sponsor and/or the interests of the individual student and students are encouraged to utilise their employment resources to place the project in context. Lecturing staff on both campuses will undertake supervision of research projects.
