The airfield consisted of a runway made of wooden frames filled with sand 1,800 by 60 meters (5,910 by 200 ft).

Its main role thus remained as a backup of the larger air stations of Ørland and Værnes.

Øysand was proposed as the site to build the German exclave Nordstern, but the plans never materialized.

[1] There was no German contractors available in Trøndelag at the time and therefore Luftwaffe organized construction with Norwegian workers, bused from Trondheim every day.

[5] Only in the summer of 1944 was the airfield upgraded to a firm, wooden structure,[6][7] This was because of difficulties in procuring sufficient wood for the runway.

A fixed wooden surface was installed on the runway in mid-1944,[6] allowing Øysand to play a role in the North Atlantic weather war.

[13] However, all that was ever realized at Øysand was the airfield and a small army base, as well as a series of prison camps.

[14] The airport was situated at Øysand in Melhus, a flat agricultural peninsula in Gaulosen, the delta of the river Gaula.
