USNS Range Recoverer


US Navy


Built 1944 as FS-278, converted to MSTS T-AG-161 in 1960, and then to T-AGM-2/USNS Range Recoverer in Nov 1960.


Note: A Feb 1966 mid-Atlantic Arcas launch was reported by the IRIG Meteorological Working Group (Document 109-62, Vol LIV, Feb 1966 Firings) as being from `Ship Sierra'. This might be the USS Sierra, but there's no other indication it was ever involved in weather rocket firings. It seems more likely that `Sierra' is just a code letter S in the phonetic alphabet (perhaps as Quebec and Victor were associated with the range ships Coastal Sentry and Rose Knot). I further speculate that the firing was a proof of concept precursor to the Zorba eclipse firings, and that Ship Sierra was in fact the Range Recoverer; obviously this is a rather tenuous guess.
