The design of the vessel involves technology transferred from the United States. It is constructed from welded panels of thin marine aluminium sheets and extrusions connected with light-weight composite constructions. The special features of the vessel are good mobility, independence of waterways and fixed port equipment, year-around operation and a small crew of only ten owing to the advanced technology.

Tuuli was commissioned in 2000. Her trial runs proved a success, and her specified capacity and maximum speed were exceeded. Fiscal reasons and doctrine change in the Navy spelled an end for the Squadron 2000 project. On December 19, 2003 it was announced that Tuuli will not enter active service and it would be presented for sale. There has been foreign interest towards purchasing Tuuli, but no further details have been given. The vessel is being stored at Upinniemi.
