Photo of the Day: Battleship USS Ordnance

Today’s POTD comes from the facebook page of Steven Zaloga.  He describes this picture as:

The “Battleship USS Ordnance” in Chesapeake Bay in the early 1920s. Some wise guys at Aberdeen Proving Ground decorated a SP Mk. I 8 inch howitzer during wading trials in Chesapeake Bay with fake masts and an anchor.
