Description“The Convoy Brook” artwork by Adolf Dehn, showing U.S. Navy blimps and a ship convoy (19579256022).jpg | Lot 3124-7: Paintings of Naval Aviation during World War II: Abbott Collection. #59: “The Convoy Brook” Artwork by Adolf Dehn. “Like maternal hens, U.S. Navy blimps hover over a sea-borne convoy alert to any danger on the horizon or beneath the surface. Airships are capable of speeds of 60 knots or more, yet can ride indefinitely over danger spots. Their cargo of depth bombs make them a deadly danger to the submarine. As convoy escorts, the lighter-than-air branch of the Navy has played its part in reopening coastal shipping lanes.” (7/10/2015). |
