Purchased by the US army in 1921 and equipped by Johnson and Phillips. Laid the 1924 Alaska cable which was manufactured by Siemens Bros., who supplied 1894 nm of cable. Returned to commercial trading in 1931 as a cannery ship for the Alaska Trading Company.

Requisitioned again in 1942 and fitted with new cable equipment which had been developed by the Sundfelt company from a sawmill winch. Used for both cable laying and harbour defence work, the latter on the US West Coast and in Alaska.
