AMERICAN ALTAIR
Historical Narrative
Vessel Name History
Mormacaltair
Green Mountain State
Green Mountain State is an Auxiliary Crane Ship (T-ACS). T-ACS
vessels are designed to offload commercial, non self-sustaining
containerships in undeveloped or damaged ports. Green Mountain State was originally built for Moore-McCormack Lines in 1965 as the break-bulk cargo ship Mormacaltair.
The ship was later “jumboized” and converted to a self-sustaining
cellular containership.
Moore-McCormack sold the vessel to United
States Lines, which renamed it, American Altair. In 1987, American Altair
entered the Beaumont Reserve Fleet in Beaumont, Texas, in preparation
for a Maritime Administration/Military Sealift Command-directed
conversion to a crane ship, which took place from February 1989 to
September 1990.
The Maritime Administration purchased the vessel
outright in March 1992 and it served in the Ready Reserve Force (RRF)
until it was downgraded to the National Defense Reserve Fleet in July
2006.
The vessel is currently part of the NDRF retention program, where
it is in logistic support status as a source of major equipment spares
for its sister ship Pacific Tracker (formerly the RRF vessel Beaver State).
