SRPA Station Igloo was a SRPA military base located in Grindavik, Iceland. Daedalus was transferred and imprisoned there by SRPA for "Project Daedalus". Nathan Hale was also brought here for mandatory testing (in order to be allowed to participate in the Sentinel Program) on July 15, 1951. However, Hale made an untimely arrival, just as the Chimera began to assault the base (which was presumably ordered by Daedalus in order to set him free). SRPA air and ground forces, consisting of F-86 Sabres and M-12 Sabertooth tanks, were unable to stop Chimeran forces, especially the Goliaths from breaching the base. In the chaos, Daedalus escaped Station Igloo, and SRPA was forced to abandon the base. The tower in the area was then successfully excavated by the Chimera, and become known as the Holar Tower. Instead of destroying the base, the Chimera made it their own.
Two years later, SRPA attacked the base with a large army, in order to assassinate Daedalus. However, the Chimera had anticipated their arrival and had set up a trap. SRPA realized this too late, and suffered major casualties as a result. In the end, Daedalus evaded his death and left SRPA with a large blow to their forces, including two Sentinels.
