We noticed that this photo was originally showing flipped. Even though the caption at the top is now backwards, the image scene now shows correctly.

lifting what appears to be one of the lattice cage mast for a US battleship, several were built there.

This crane existed in 1907 already, s. photo in the Daily press., March 24, 1907, Image 21 chroniclingamerica.loc.gov/lccn/sn83045830/1907-03-24/ed-...

And this 1900 article is illustrated by a photo of Hercules in 1898: "In view of the attention which the management has given to the question of the handling of material it is quite natural that the equipment of derricks and cranes should constitute one of the most interesting features of the Newport News yard. First place must be given of course to the 150 ton revolving derrick Hercules. The derrick jib is capable of having its outer end raised or lowered thus giving to the hoisting blocks which depend vertically therefrom a movement of rotation about the center of the derrick, and also one of translation in and out from the center. With the outer end of the jib in its lowest position the hoisting blocks will, on rotation of the derrick, describe the circumference of a circle 207 feet in diameter; with the jib in its highest position the diameter of the circle described is 88 feet. Thus the derrick may operate on weights lying anywhere between these two circles as boundaries. The maximum load of 150 tons can be handled only within a ring the maximum and minimum diameters of which are 147 and 88 feet respectively, but weights not exceeding 70 tons may be handled throughout the entire field of operations. The maximum elevations above mean high water,, for the hoisting blocks, are 118 and 69 feet respectively in the high and lower positions of the jib. The derrick is revolved by duplicate sets of machinery. books.google.com/books?id=Eb1MAAAAYAAJ&pg=PA501&l...

This picture ran in the New York Tribune Review in April, 1918, attributed to Underwood & Underwood. navsource.org/archives/01/pdf/012746.pdf An online source (probably thinking the photo dated from April, 1918, guesses at the ship involved. "Assuming this photograph wasn't aging in a camera somewhere, the mast most likely belongs to the Michigan (BB-27). The only other battleship built within a year of this date was the Mississippi (BB-41), which was commissioned 18 December 1917." www.navsource.org/archives/01/27b.htm
