Lindormen was the first of two similar minelaying ships built at the Svendborg Skibsværft shipyard for the Danish Navy.

[1] Her sister ship, KDM Lossen (English: Lynx), was also donated by Denmark two years later in 2006, but not directly to the Estonian Navy.

The ex-Lossen began serving with the Estonian Maritime Academy as a civilian training vessel named: MS Kristiina, for new marine officers.

EML Tasuja was used on active duty as the naval diving vessel of the Estonian Mineships Division, while her sister ship was held in reserve and used for training.

Shortly thereafter they took her sister ship (in Danish service: Lossen, then Estonian Kristiina) out of reserve and commissioned her into active duty as EML Wambola (A433) as her replacement.
