[4][5][6][7] The proposed launch vehicle under this programme is the RS1 from ABL Space Systems, a US-based company developing 27 m tall rockets capable of carrying payloads up to 1000 kg into a sun-synchronous orbit.

The plans also document proposals for a Range Control Centre at the former RAF SaxaVord complex, fuel storage facilities at Ordale Airport at Baltasound, and improvements to the launch site's approach roads.

[14][15] On 29 March 2021, Historic Environment Scotland (HES), a statutory body, refused consent for the development of the spaceport on the grounds it would impact a scheduled monument of national significance – the Chain Home radar station at Skaw.

[20] In May 2023, spaceport CEO Frank Strang announced a new $137 million debt financing package during a UK Parliamentary Science and Technology Committee hearing.

"[24][25] In April 2024, the spaceport was granted a range licence by the Civil Aviation Authority, allowing them to control the sea and airspace to the north of the site around orbital launch trajectories.

[28][29] In October 2024, UK rocket manufacturer Orbex announced their intention to mothball their proposed Sutherland spaceport on the Scottish mainland near Tongue and relocate planned launches to SaxaVord (citing its more advanced state of development).
