The U.S. Air Force said that it is considering reuse of the previous Over the Horizon Backscatter (OTH-B) radar sites to augment the U.S.-Canadian North Warning System (NWS).

In fiscal 2024 the Air Force requests more than $423 million for rapid prototyping of OTH-B to supplement NWS, including funds to satisfy a classified U.S. European Command requirement, $360 million to fund the first two OTH-B sites in the U.S., and funds for the detection of stratospheric balloons and unidentified aerial phenomena.
