With its 3.8 meter primary mirror (150 inches), The United Kingdom Infrared Telescope (UKIRT) is one of the largest infrared telescopes in the world. It is currently funded by NASA and operated under scientific cooperation between Lockheed Martin Advanced Technology Center, the University of Hawaii, and the U.S. Naval Observatory. However, it is scheduled for decommissioning should the hotly contested Thirty Meter Telescope (TMT) ever become a reality.
