Capps had recently assumed the duties of chief of the Bureau of Con-
struction & Repair and was defending his predecessor’s design for the
Delaware-class dreadnoughts currently under construction. Capps had
graduated from the Naval Academy in 1884, four years after Sims, but was
entitled to the temporary rank of rear admiral as chief of a bureau.
71
News-
papers supporting Sims sneered at “Rear Admiral” Capps, but his lengthy
experience as a naval architect qualified him to head his bureau.
In his statement to the committee, Capps refuted the charges made by
Sims and his compatriots.
72
Capps presented comprehensive data on con-
temporary warship design practices that supported the bureaus’ contention
that American warship design philosophy was comparable to foreign prac-
tice. In contrast to the claim made in the Reuterdahl article, the data also
indicated that American armor belt design was consonant with the design
practices of the British and Japanese navies.
73
Capps reported that the
Japanese Aki-class battleship “indicates clearly that the Japanese, with all
their experience derived from the battle of the Sea of Japan, have con-
firmed in 1906, so far as concerns freeboard, water-line armor protection,
height of guns, etc., the American design of two years previous, that is the
Connecticut-Vermont class.”
74
Capps pointed out that Sims’s ideal battleship, HMS Dreadnought, had
only one-third of her coal on board when the design waterline was calcu-
lated. When fully loaded, Dreadnought was almost 2 feet deeper in the
water than when designed, submerging her armor belt even farther than
the worst American ship. When Sims suggested that Capps’s data was in
error and that a little legwork by Capps could “dig out” the correct infor-
mation, Capps’s reply was peremptory: “It is not a case of digging it out; it
is simply a case where those who have to deal with these things and are re-
sponsible know, and those who carelessly criticize do not know.”
75
Technically, Sims was correct in accusing the Bureau of Construction
& Repair of arbitrarily establishing the waterline at which the armor belt
was installed, but it was a decision designed to foster strategic consonance
of the battleship force. In 1896, the Walker Board had recommended fix-
ing the design waterline based upon a two-thirds load of coal, stores, and
the like.
76
But given the strategic and tactical necessity for battle fleet in-
tegrity, an important Mahanian concept, the Board on Construction had
decided that the varying rates of fuel consumption of different classes of
battleships had to be taken into account. The “normal” load (upon which
the design waterline was based) should include enough coal to provide a
Technological Change and the United States Navy
