FAQs
Defence systems are becoming increasingly complex, combining electronics, software, communications, control and autonomous technologies. This course gives you the engineering knowledge and practical experience to understand how these technologies work together as integrated systems. You’ll develop your skills through practical learning and project work, applying engineering principles to realistic defence challenges while developing the problem-solving and systems-thinking skills valued across the engineering sector.
A Defence Systems Engineering degree prepares you for engineering careers in defence, aerospace, security, critical infrastructure and advanced technology. Graduates can work in areas such as systems engineering, electronics, embedded systems, robotics, autonomous systems, software engineering and systems integration. The broad engineering skills developed on the course can also be applied to roles outside the defence sector.
Defence Systems Engineering applies engineering principles to the design, development and integration of complex systems used in defence and security. It brings together hardware and software to create systems that can sense, communicate, process information and respond to changing conditions. On this course, you’ll explore how different engineering disciplines work together to create reliable and effective systems for challenging real-world environments.
No. You do not need previous military experience or a background in the armed forces to study this degree. The course focuses on engineering and technology, with defence providing an important context for applying your knowledge. The skills you develop can also lead to opportunities across the wider engineering and technology sectors.
The two courses share a focus on the technologies used in modern defence, but they have different areas of emphasis. has a broader computing and technology focus, while Defence Systems Engineering places greater emphasis on engineering the physical and cyber-physical systems that support defence applications. You’ll develop a deeper understanding of how hardware, electronics, embedded computing, control and autonomous technologies can be designed and integrated into complex systems.
