The Unit

Astra is the RAF's approach to grassroots innovation. It is enabling the whole force to deliver meaningful change through innovation, challenging the status quo, and continuous improvement.

A core team works within Air & Space Command and is supported by dedicated specialists on units across the RAF. There is also a continuously growing network of innovators in the whole force who are delivering change on a daily basis.

To succeed in a rapidly changing world, the RAF must be prepared to confront future threats, especially as technology advances. Our ability to think differently, question the norm, and embrace innovation will be crucial to our future success. This is why Astra is a part of how the RAF does business - unleashing the ingenuity of our people to rapidly identify and solve the problems that matter to them and our operational effectiveness.

What we do

Astra enables our people to innovate, challenge, and improve.

Our approach to grassroots innovation includes using new technology or existing technology in a new way, challenging unhelpful policy, and the pursuit of continuous improvement.

In today’s highly competitive and contested world, harnessing the power of grassroots innovation has never been more important to ensure the RAF continues to deliver world class air power.

Astra allows the RAF to tap into the energy, creativity, and determination of the whole force to deliver meaningful change, including for operational problem sets. It is enabling those at the front line to identify what is holding them back, where efficiency or effectiveness can be enhanced, or where bureaucracy is causing issues.

Most importantly, it's also giving the whole force the tools and support to deliver meaningful change and address the problems that matter to them.
