1961 ("BMEWS deputy program director" by 1964—he was reassigned from the BMEWS SPO to the "Space Track SPO" on February 14, 1964.) Air Defense Command Thule operations transferred from civilian contractors (RCA Government Services) to Air Defense Command on January 5, 1962; and 1962 sinkholes formed in the drainage ditch at "Scanner 6". By mid-1962, BMEWS "quick fixes" for ECCM had been installed for Thule "to recognize when it was being jammed." An RCA AN/FPS-49A Radar Set with specialized radome for Thule weather was installed by December 1963, and Thule multipath testing was completed by May 1964. In 1967 when the system cost totalled $1.259 billion, BMEWS modification testing ended on May 15 ("completion of the BMEWS"); and the Bomb Alarm System caused a false alarm during the 1968 Thule Air Base B-52 crash (the system was deactivated in 1970.) In June 1980, Thule's FPS-49A radome by Goodyear "burnt to the ground" and was rebuilt, and a late 1960s satellite communications terminal was moved from the Thule P-Mountain site to Site J in 1983. To replace AN/FSQ-28 predictors, a late 1970s plan for processing returns from MIRVs installed new Missile Impact Predictor computers and was complete by September 1984. After being contracted for Thule on July 29, 1983; construction of an AN/FPS-120 Early Warning Radar was started on November 7, 1984, the "array plate" was complete on June 26, 1985, and the 1st satellite track was on June 8, 1986. Solid State Phased Array Radar Thule's BMEWS radars were deactivated in June 1987. The BMEWS system at Thule had been "replaced" by the SSPARS AN/FPS-120 with "two-faced…phased array radar [completed] in 2QFY87" (January–March). with 240 degree detection arc The AN/FPS-49A was intact and in disrepair in 1996, and the antenna and radome were removed by 2014. After the Danish parliament approved, Raytheon was contracted in 2005 to upgrade Thule's "Early Warning Radar" as part of the larger Ground-Based Midcourse Defense program. Intended to be ready in 2008, the installation was actually completed on June 24, 2009. Thule's AN/FPS-132 Upgraded Early Warning Radar (UEWR) completes about 10% of the United States' observations of Earth orbiting satellites.
