S-259

The Marconi S-259 is a medium-range air surveillance radar operating in the L-band. In the Royal Air Force, it was designated Type 95. The radar is air transportable and is essentially a reverse-engineered version of the AN/UPS-1 with substantially increased transmit power and used the same antenna.
