The United States Naval Observatory(USN0) has been using hydrogen masers for over six years as part of the USNO Master Clock. The Naval Research Laboratory(NRL) has also been using masers references as part of the NRL Clock testing facility since September 1985. The masers reported on in this paper will include the Smithsonian Astrophysical Observatory VLG-11, VLG-12 and masers from the Sigma Tau Standards Corporation. This paper will describe the operation of the masers at USNO and NRL including stability, aging rates, and reliability.
