It’s been designed to ‘see through’ all the invisible ‘clutter’ in our skies created by television, satellite and phone signals and can cope with more than 10,000 mobile phone signals trying to jam it.

All in all, it’s five times more effective than its predecessor 996 (officially, Artisan is designated Type 997).

So far Artisan has been fitted to 11 of 13 Type 23 frigates, flagship HMS Ocean, assault ship HMS Bulwark, future flagship HMS Queen Elizabeth.

It’ll be fitted to her sister Prince of Wales, the remaining two 23s in their refit cycle, HMS Albion as she returns to front-line duties and there’s a test variant installed at the MOD’s Portsdown Technology Park overlooking Portsmouth.
