The airport was built and commissioned in 1940 as RAF Grimsetter for the defence of the Scapa Flow naval base. In 1943, the Royal Navy's Fleet Air Arm took over, as RNAS Grimsetter then HMS Robin. Control passed in 1948 to the Ministry of Civil Aviation and in 1986 to Highlands and Islands Airports.[3]

On 6 July 1943, RAF Grimsetter was transferred on loan to the Admiralty and known as Royal Naval Air Station Grimsetter (RNAS Grimsetter). On 15 August, it was commissioned as HMS Robin, as a satellite to RNAS Hatston (HMS Sparrowhawk),[4] located to the north west of Kirkwall.

Hydrogen production by electrolysis of water was well under way in late 2020 in Orkney, where clean energy sources (wind, waves, tides) were generating excess electricity that could be used to produce hydrogen gas (H2).[7] A plan was under way at Kirkwall Airport to add a hydrogen combustion engine system to the heating system in order to reduce the significant emissions that were created with older technology that heated buildings and water. This was part of the plan formulated by the Scottish government for the Highlands and Islands "to become the world's first net zero aviation region by 2040".[8]
The airport is notable for the signage on the terminal roof written in runes. The symbols spell the word 'Krimsitir' or 'Grimsetter'[9], the name of the bay next to which the airfield is located, which was similarly the name of the former RAF base.
