Royal Corps of Naval Constructors

The Royal Corps of Naval Constructors (RCNC) is an institution of the British Royal Navy and Admiralty for training in naval architecture, marine, electrical and weapon engineering. It was established by Order in Council in August 1883, on the recommendation of the naval architect Sir William White. Its precursor was the Royal School of Naval Architecture, London.

According to the Royal Navy's Books of Reference 3 Chapter 46, it is a "civilian corps and an integrated part of the Defence Engineering & Science Group". Members in certain posts who do not hold commissions are eligible to wear a uniform similar to that of the Royal Navy and are accorded the same respect as commissioned officers.
