MM/SPQ-2

The MM/SPQ-2 was an Italian naval radar produced by SMA. It was a multifunction radar performing the functions of surface and low altitude search as well as navigation.^[1] The radar equipped many ships of the Italian Navy, including the Alpino-class frigates, Andrea Doria-class cruisers, Audace-class destroyers, Bergamini-class frigates and Vittorio Veneto, and, in its upgraded SPQ-2D form, was exported to Canada for the Iroquois-class destroyers. It was developed into the MM/SPS-702 and MM/SPS-703.^[2]
