Whether this qualifies as New Deal is fine point; it's public money spent labor and material to improve existing shipyards. In any case there are two explicit references to the WPA in the document; the one on page 60 stating that in 1938 WPA Projects were added as a new subdivision of the federal Bureau of Yards and Docks. And on p.24 it notes that "such work as could be done" in 1935 was financed (in part) by "funds provided in FDR's 1935 Emergency Relief Appropriation Act, which was New Deal legislation.

Part II of the same document, p.168: "a considerable amount of work ... was accomplished during this period, partly under naval public work appropriations, but principally through allocations from National Industrial Recovery Administration, Civil Works Administration, Works Progress Administration, and Public Works Administration appropriations for unemployment relief during the Depression.
