Launch Date, USS O'Bannon (DD-450)
In my own research I have come upon a factual inaccuracy reported by Naval History and Heritage Command and Wikipedia regarding the launch date of USS O'Bannon (DD-450). The inaccurately reported date, 19 February 1942, while accurate for sister ship USS Nicholas (DD-449), should be 14 March 1942 for O'Bannon. (See NavSource. This can be confirmed by Bath Iron Works.)

There exists an image taken of the sister ships, side by side on 19 February just prior to the launch of Nicholas, in which the visual evidence makes clear the two ships were not launched on the same day, an awkward business at best where the launch site is on a river subject to tidal effects.
