Commodore (Cdre) is a rank of the Royal Navy above captain and below rear admiral. It has a NATO ranking code of OF-6. The rank is equivalent to brigadier in the British Army and Royal Marines and to air commodore in the Royal Air Force. Commodore has only been a substantive rank in the Royal Navy since 1997. Until then the term denoted a functional position rather than a formal rank, being the title bestowed on the senior officer of a fleet of at least two naval vessels comprising an independent (usually ad hoc and short-term) command. (In this case, for instance, a lieutenant in substantive rank could be a commodore for the term of the command.)
