One Hundred Years - 1920-2020

The Association of Royal Navy Officers (ARNO) was formed in 1920. Its initial aim was to help recover retired pay that had been withheld from Naval officers recalled to service in the Great War. Five years later, ARNO was reconstituted by Vice Admiral FW Caulfeild CBE with a broader remit to support serving and retired officers and their families. While much has changed in both the Service and the wider world, that central defining role remains the same.

Today ARNO members enjoy a wide range of rewards, social events and networking opportunities, regular publications and the chance to keep in touch with the Naval Officer family at home and online.


The Association of Royal Navy Officers (ARNO) is a thriving membership organisation for serving and former Naval Service Officers and their families. We have almost 5,500 members in the UK and overseas, of all ages and backgrounds, and at every stage in their lives and careers.

ARNO works in partnership with the Royal Naval Officers' Charity (RNOC), which provides a wide range of practical, financial and emotional support to the Naval Officer family. The charity awarded grants in excess of £400k in 2020.
