56 ships left Norfolk, VA with c 153000 tons of cargo on 6 Jun 1951, under the command vessel Monrovia, for North Star Bay in NW Greenland as Operation Bluejay, to build a new USAF base at Thule.
Embarked with S-51 and float equipped Bell 47. Fuel and equipment was brought ashore, mostly by DUKW. The base was initially constructed between Jul and Oct 1951, with the airstrip ready by 8 Aug to allow flights in and out and provide ground support.
It has been upgraded and modernised from time to time since then.
