Rocket permission Air Navigation Order

Launch activity of a large rocket capable of operating below the stratosphere (about 47km altitude) requires a permission under Article 96 of the Air Navigation Order (ANO). Rocket launches carried out under the ANO are therefore sub-orbital.  

A large rocket is defined as a rocket with a total combined motor impulse of greater than 10,240 Newton-seconds.

Launch activity of a rocket capable of operating above the stratosphere is regulated under the Space Industry Act 2018 and requires a licence.  

How do I apply?

Please complete our online application form. We ask you for information like your planned launch site, key people involved in the launch and details of your rocket and your planned flight, including:

  • Planned apogee (maximum altitude) the rocket will be reaching.
  • Launch azimuth (angle of the launch relative to true north).
  • Inclination of your launch (relative to the ground).
  • Technical particulars of the rocket.

Please email your completed application to commercialspaceflight@caa.co.uk

What do I need to send with my application?

The following information needs to be sent with your application:

What else do I need to know?

We encourage you to speak to us before you apply to discuss your planned launch. You can book a pre-application meeting, this will help us to understand your proposed mission and timescales. We can also discuss the requirements you need to fulfil as part of your application.

To grant a permission we need to be satisfied that your safety case has:

  • Identified the hazards and risks of your launch.
  • Reduced the risks to As Low As Reasonably Practicable (ALARP) and that those risks are acceptable.

For more information on what you will need send us as part of your application please read our guidance Guidance on applications to launch a large rocket under the Air Navigation Order and Assessing ALARP and acceptable risk.

In addition to a launch permission, you may need to launch within segregated airspace. If you are not using an existing Danger Area, you may need to apply for a Temporary Danger Area (TDA).

To apply for a TDA you must submit a Statement of Need. The airspace change process for a TDA takes a minimum of six months so early submission of a Statement of Need is recommended. Any large rocket permission will be conditional on airspace approval.
