Iron Duke can see far with new radar
24 June 2013
After 16 months out of action undergoing a major overhaul in her home base, HMS Iron Duke has returned to sea.
The frigate left Portsmouth over the weekend to begin trials – including testing one of the world’s most advanced radars.

AT SEA for the first time in 16 months following a major overhaul in her home base is the new-and-improved HMS Iron Duke – the first RN ship to be fitted with one of the most advanced radars in the world.
Among many other enhancements, the 22-year-old frigate is testing Artisan – a 3D radar which spins atop Iron Duke’s main mast and is five times better than the old radar it replaces.
She’s the first of the Type 23 fleet to receive the Gucci new piece of kit as part of a £100m programme to fit the frigates as well as the Royal Navy’s two future aircraft carriers.
Artisan could also be the principal air radar of the Type 26 combat ship, successor to the 23s, which enter service next decade.
For now, Iron Duke is basking in the accolades and superlatives surrounding the new radar.
It can spot something as small as a cricket or tennis ball travelling at three times the speed of sound more than 25 kilometres (15 miles) away.
Impressive. But it’s just the beginning of the gee-whiz facts.
It’s built out of the same lightweight carbon glass fibre materials found on a Formula 1 cars and weighs just 700kg (1,540lb) – slightly heavier than an F1 racer and driver.
As well as being able to track up to 800 targets simultaneously, it can do so if they’re 200 metres from Iron Duke – that’s roughly the width of the entrance to Portsmouth Harbour – or 200 kilometres (125 miles) away.
Put another way: Iron Duke could sit in her home base and follow aircraft flying into Heathrow, Gatwick, Southampton, Stansted, Bournemouth, Bristol, Cardiff, Exeter and Birmingham international airports.
On top of accuracy it’s packed with anti-jamming features – it isn’t bothered by interference from 10,000 mobile phone signals – and can pick out targets against a background of electronic noise and interference.
The ship has received other weapons upgrades and improved air conditioning for forays into hot parts of the world.
Sailing after well over a year out of action, said Iron Duke’s Commanding Officer Cdr Tom Tredray, “marks a significant milestone in the regeneration of the ship.
“We’re looking forward to taking the first Artisan radar to sea – and testing the Royal Navy’s latest cutting-edge technology.”
