NSS Annapolis, officially known as Naval Communications Station Washington, D.C. Transmitter or NavCommStaWashingtonDC(T), was a Very Low Frequency (VLF) and High Frequency (HF) transmitter station operated by the United States Navy. It was located at Greenbury Point, in Anne Arundel County, across the Severn River from Annapolis, Maryland at coordinates 38°58?40?N 76°27?12?W? / ?38.97778°N 76.45333°W? / 38.97778; -76.45333. NSS Annapolis was used by the USN for submarine communication. The station consisted of an umbrella antenna supported by a 1,200-foot (365.76 m) high central mast, which was insulated against ground, 6 guyed masts of 800-foot (243.84 m) and 3 freestanding towers of the same height, similar in design to the towers of the transmitter at Junglinster.
