Almost three years to the day after we first wrote about this subject, the Royal Navy has announced the fielding of their new Royal Navy Personal Clothing System bersion of the No 4 Action Working Dress which has remained essentially unchanged since the Second World War. The first command to receive this update is the HMS Lancaster.
The uniform is dark blue and made from FR materials. While it is certainly a Navy working uniform, its shares some features with the PCS uniform worn by the Royal British Army, Royal Marines and Royal Air Force. For instance, rank is now worn on the chest. However, the Navy Ensign is proudly displayed on the left shoulder and trade badge on the right.
This Royal Navy graphic gives you a look at the differnces between the old and new uniforms and layers that make up the Royal Navy Personal Clothing System which include undergarments, shirt and trousers, fleece and shell.
