The Urlik Utrek Federation waged a very costly war against the invading Mantae for several years, at times DDS observers were alarmed at Utrek losses and the prospect of the Utrek collapsing (enemies though the Utrek are they are a known quantity unlike the Mantae). The Utrek were so short of ships at one stage that they even bought back obsolete Kalahati Tuuls from some export customers.
The war ended after the Mantae were pushed back out of Utrek territory (at one stage the Mantae were only 9 light years from the Utrek capital world) but some intelligence indicates that the Mantae have gone on the attack again. Around 30 Utrek ships have been redeployed from the border with the DDS according to ISSF, a Dino merchant has also reported detecting weapons fire from near the Utrek-Mantae border.
