Flottillenadmiral, short FltlAdm in lists FADM, (en: Flotilla admiral) is the lowest flag officer rank in the German Navy, corresponding to command of a US Navy Rear Admiral (lower half) or Commodore (Royal Navy). It is equivalent to Brigadegeneral in the Bundeswehr or to Admiralarzt/Generalarzt, Admiralapotheker/Generalapotheker in the Zentraler Sanitätsdienst der Bundeswehr.
Its rank insignia, worn on the sleeves and shoulders, are one five-pointed star above a big gold stripe and a nerrow one (without the star when rank loops are worn). It is grade B6 in the pay rules of the Federal Ministry of Defence.
The sequence of ranks (top-down approach) in that particular group is as follows:
