compared to the massive outlay of Wilson’s 1916 Program, promised to keep
the navy well below the maximum size allowed under the treaty.
With the battleship’s evolution limited by treaty, the navy came under
vigorous attacks from aviation advocates, who claimed that a $10,000 air-
plane could sink a $10 million battleship.

The sensational aerial bom-
bardments against captured German and obsolete American battleships
conducted in 1921 provided aviation supporters with ammunition for their
fight. The bombing trials yielded dramatic photographs of phosphorus and
high-explosive bombs detonating on the huge battleships as fragile, biplane
bombers flew overhead. However, the battleships that were bombed were
anchored, unmanned, unarmed, and, by virtue of their age, markedly less
resistant to aerial bombing than later designs.

The German battleship
Ostfriesland, sunk in the tests off Cape Henry, Virginia, in July 1921, had
been subjected to repeated attacks over a two-day period. During the first
day, sixteen of sixty-nine bombs ranging in size from 230 to 2,000 pounds
scored hits. On the second day, three out of eleven 1,000-pound bombs hit
the ship, while three of the six 2,000-pound bombs exploded in the water
close aboard. With most of her watertight fittings not fully repaired after
her battle damage at Jutland and no damage control teams on board to fight
the flooding, Ostfriesland sank.

The trials did not provide conclusive
proof of the battleship’s obsolescence, but a significant segment of the pub-
lic believed it was vulnerable to air attack.

Faced with this public relations fait accompli, the naval hierarchy
worked hard to restore a common sense of the battleship’s invulnerability.
The navy argued that a fully manned battleship with antiaircraft guns,
steaming at full speed, could thwart an attack from the air. Even if a bomb
should hit, the navy claimed that the resulting damage would hardly prove
fatal in light of the “superiority” of U.S. armor designs over those installed
on British and German ships which had survived numerous large-caliber
shell hits at Jutland.
In testimony before the House of Representatives’ Joint Military and
Naval Affairs Committee, Rear Admiral William A. Moffett, chief of the
Bureau of Aeronautics, maintained that the nation’s “first line of defense
is the main fleet . . . the second line of defense would be auxiliary vessels
of the fleet [cruisers, destroyers, and submarines] and the third line of de-
fense is our coast fortifications, augmented by the Army Air Service.”

a pejorative aside, Moffett doubted the ability of army flyers to defend
