Notice of intent to use a brand name product. The Naval Facilities Engineering Systems Command, Pacific (NAVFAC Pacific) is performing a market survey to determine if other potential sources of supply can provide a radome. The products must have equal performance and listing/approval requirements as listed below.

FY26 Military Construction P-219, Guam Defense System (GDS) Forward Operating Sites, Guam, will construct a total of three sites to support the GDS. Two of the Sites (Sites 13 and 15) are located on Andersen Air Force Base (AAFB) and Site 6 is located on Naval Base Guam.

Collectively, these Sites are referred to as Tranche 1. Site 15 requires one (1) radome with the following characteristics:
