These guns constituted the main armament for the New
Yorks, Nevadas,
and Pennsylvanias. First
test-fired in January 1910, the new weapon pleased the Navy as being
"remarkable for the uniformity of results" (quoted in Friedman 1985).
However, they
suffered from problems in both barrel design (resulting in excessive
droop, reducing accuracy) and magazine arrangements. The former
was mitigated by relining the barrels and the latter concern was
dismissed after tests suggested the potential for a magazine explosion
was not as great as originally feared.
