Destroyers

USS Cassin Young (DD-793) on January 13, 1944, two weeks after commissioning on December 31, 1943 in San Pedro Harbor in Measure 32 colors: dull black and light gray. The depth charges and rack on the stern should have been painted black according to the design drawing and directions. This could have been a mistake or simply that the painting is not complete. The whaleboat is also missing from the starboard side.

An aerial view of Cassin Young on January 15, 1944, again showing only a solid deck blue deck. This may be because the initial drawing for 7D for the Fletcher class did not provide any deck pattern.

The official caption for this photo says that this is USS Monssen (DD-798) shelling Garapan, Saipan on June 22, 1944. However, the side pattern is a very close match to Cassin Young, (compare to previous photo) Cassin Young was also involved in the bombardment of Saipan, and Monssen has been photographed wearing 6D, so I believe this to be actually Cassin Young. The enlarged inset shows the hull number could be 798 or 793.

A later photo of Cassin Young at sea from the starboard bow on October 24, 1944. She is transfering wounded from USS Princeton (CVL-23) to USS Lexington (CV-16). Note the peeled paint on the bow and side.

This is an unidentified square bridge Fletcher, probably USS Cassin Young (DD-793), wearing camouflage 32/7D. This ship is making a transfer with USS Ticonderoga (CV-14) on November 11, 1944. Many of the patches of peeled paint match those in an October 1944 photo of Cassin Young.
