DASR Nellis Redacted J&A

DASR is a terminal air traffic control radar system that replaces current analog systems with new digital technology. The DASR system is a critical component of the National Airspace System (NAS) infrastructure. The FAA nomenclature for the DASR radar is ASR-11, the DoD nomenclature is AN/GPN-30. The ASR-11 is replacing existing ASR-7, ASR-8 and AN/GPN-12, -20 and -27 systems. These older radars, some over 20 years old, were replaced to improve reliability, provide additional weather data, reduce maintenance costs, improve performance, and provide digital data to new digital automation systems for presentation on air traffic controller displays.

A DASR was never delivered to Nellis AFB under the current DASR Production Contract. A decision was made earlier in the program to deliver the ASR-9 airport surveillance radar currently at Nellis from the Federal Aviation Administration (FAA) because the Lead and User commands (Air Force Flight Standards Agency and Air Combat Command) did not want to wait for the lead time required to deliver a DASR. This ASR-9 is the only radar of its type providing air traffic control on USAF bases. This is a one of a kind asset for the USAF and logistical support is provided by the FAA. Since that time a new base gymnasium was constructed at Nellis AFB which causes interference problems for the ASR-9 operation and the Lead and User commands revived the requirement for an ASR-11 DASR at a new location at Nellis AFB.
