Director of Naval Ordnance (Royal Navy)

The Director of Naval Ordnance was an officer of the Royal Navy responsible to the Board of Admiralty for the design and development of weapons for the Fleet. Established on a temporary basis as the position of Director-General of Naval Ordnance in 1866, in 1886 it became the Director of Naval Ordnance and Torpedoes, reflecting the growing significance of the torpedo in the Navy.

In 1917 the Director of Naval Ordnance and Torpedoes was divested of his responsibilities for torpedoes and mines, and the office became Director of Naval Ordnance again.
