The real reason sailors wear white suits on Royal Navy warships explained

What the Royal Navy’s white suits reveal about a ship's threat level

When Royal Navy sailors put on sealed white suits, it means they're not just training – they're preparing for a real threat.

As CSG25, led by HMS Prince of Wales, passed through the Red Sea off the coast of Yemen, it was on high alert in an area where Houthi rebels have launched missiles and drones at ships.

As the carrier sailed through the danger zone, the crew were seen wearing white overalls, signalling the ship was at its highest alert level – known as State 1. 

Unlike the standard flame-resistant uniform known as Rig22, these sealed suits haven't been repeatedly washed, so they offer better protection in the event of fire or explosion. They're only worn when a warship is at action stations.

In these conditions, sailors also carry a grab bag – with a life jacket, anti-flash gear, and sometimes body armour and a helmet.

HMS Richmond, a Type 23 frigate, was also seen operating in similar kit during the Red Sea transit.

All compartment doors would have been sealed – a setting called Condition Zulu – to improve survivability if the ship were hit.

Once clear of the high-threat area, the crew would have switched to defence watches, with only half on duty at a time.

Also visible during the alert was an F-35 fighter jet taking off from the carrier, armed with ASRAAM missiles that can intercept drones or cruise missiles.
