All the corps of regiments of the Army have with the honorific title "Royal" discarded. E.g., The Royal Regiment of Artillery becomes, The Regiment of Artillery and The Royal Tank Regiment becomes, The Tank Regiment. There were several regiments with names prefixed Queen's Own and King's Own, they would have to be dropped. E.g. The Kings Own Border Regiment becomes the Border Regiment.
There used to be King's and Queen's Regiments, these presumably become the President's regiments or get new names based on their recruiting areas. Similarly regiments named after members of the Royal Family, e.g. Prince of Wales Regiment, are renamed after their recruiting regiments. Or they are renamed after republican heroes, e.g. Oliver Cromwell's Regiment.
The two new aircraft carriers probably get renamed Oliver Cromwell and Republic respectively. As it happens Churchill when he was First Lord of the Admiralty wanted to name one of the Queen Elisabeth's, Oliver Cromwell.
But it goes further than that...
- No more Royal Mail and therefore no more Royal Mail Ships (RMS) so the RMS Titanic becomes the Consignia Ship Titanic.
- The Royal Research Ship Boaty McBoatface becomes the Research Ship Boaty McBoatface.
- The Royal Shakespeare Company becomes the Shakespeare Company.
- The Royal National Lifeboat Service becomes the National Lifeboat Service.
To name but a few.
