Part of Kongsberg’s work included delivering associated
hardware and software and assembly of the radar before installation. The
company said delivery and installation of the first radar at the Gyrihaugen
site in Ringerike, Norway, is expected to be completed by the end of 2025.
While the delivery and installation of all radars are expected to be completed in 2030.
It is a ground-based, 3D, AESA, L-band multifunctional
long-range radar and incorporates Gallium Nitride (GaN) technology. The radar
antenna can rotate at six revolutions per minute in 360-degree coverage with a
maximum detection range of 555 kilometres. The non-rotating mode provides 90-degree
coverage with a maximum detection range of 1,000 kilometres. The TPY-4 radar
can detect and track targets flying at an altitude of 30 kilometres and surface
targets at -6 degrees in support of land-based maritime surveillance. The first
production of the TPY-4 was completed in May 2022 and is planned for launch in
2023.
