Type 997 Artisan radar

The Type 997 Artisan (Advanced Radar Target Indication Situational Awareness and Navigation) is a medium-range air and surface surveillance 3D radar developed and built by BAE Systems for the United Kingdom's Royal Navy. As of 12 January 2017, it has been fitted to 11 of 13 Type 23 frigates, flagship HMS Ocean, assault ship HMS Bulwark, future flagship HMS Queen Elizabeth. It will further be fitted to HMS Prince of Wales, the remaining two 23s in their refit cycle, HMS Albion as she returns to front-line duties.

The Type 997 Artisan has a range of 200 m - 200 km at 30 RPM and is reportedly capable of tracking more than 900 targets at once. BAE Systems state that Artisan is capable of tracking targets the size of small birds or tennis balls travelling at Mach 3 with "unrivalled detection performance and world beating electronic protection measures against even the most complex jammers".
