B2 Radar Cross Section
B-2 Radar Cross Section
Request for Information:
FA8224-20-R-0228
1.0 Notice
This is not a solicitation, but rather a request for information for market research purposes only. It is not to be construed as a commitment by the Government to issue a solicitation or ultimately award a contract. The Air Force will NOT be responsible for any costs incurred by interested parties in responding to this notice.
1.1 Purpose
The purpose of this request is to find interested companies in designing, building and installing radar equipment that will be placed in a facility located at Hill Air Force Base (AFB), Utah. The Government will use this information to determine the best acquisition strategy for this procurement.
2.0 Program Details
Hill AFB is building a new Composite Aircraft Antenna Calibration (CAAC) facility that will perform multiple radar functions. One of these functions is to measure the RCS of B2 flight controls and edges. The building will have general office spaces, radar rooms, antenna rooms, anechoic chamber, radar control rooms, and a preparation area (refer to Preliminary Layout drawing).
For the B2 RCS measurements, B2 components will be uncrated and prepped in the preparation area. The B2 component is placed into a fixture provided by the government. The fixture is then mounted to a pylon via an adapter. The pylon is moved into the anechoic chamber and locked into place. The part under test is pitched in elevation (EL) and then rotated in azimuth (AZ) while the radar measures the signature of the part.
