rather than product lines: chemistry, mechanical engineering, applied physics,<br />
and metallurgy. By the 1970s, for example, the station (renamed the Marine<br />
Engineering Laboratory in 1963) had introduced, in collaboration with<br />
commercial engine manufacturers, a new generation of nickel- and cobalt-b<strong>as</strong>ed<br />
superalloys for use in the blade <strong>as</strong>semblies of marine g<strong>as</strong> turbines operating in<br />
corrosive saltwater environments, and it had also compiled an impressive record<br />
of achievement in the fields of machinery silencing and vibration dampening.<br />
In the atomic power field, station engineers had made significant contributions<br />
to the improvement of shaft bearings, auxiliary diesel engines, reactor piping,<br />
and fire-resistant hydraulic fluids used in the propulsion systems of nuclear<br />
submarines. 76<br />
The Engineering Experiment Station cultivated a broad and diversified<br />
knowledge b<strong>as</strong>e in ship propulsion technology that supported rather than fulfilled<br />
the Navy’s ambitions for shipboard atomic power. The David Taylor Model B<strong>as</strong>in,<br />
by contr<strong>as</strong>t, played a larger and more direct role in the development of America’s<br />
Cold War nuclear submarine fleet, albeit on a smaller scale than the participating<br />
industrial firms contracted by the Bureau of Ships. The private sector completed<br />
the bulk of the R&D and production for the nuclear navy. 77 Nevertheless,<br />
submarine development at the model b<strong>as</strong>in proceeded along several different but<br />
related lines. The b<strong>as</strong>in’s long-standing expertise in hydrodynamics and related<br />
scientific disciplines and expanding computational capability after World War<br />
II enabled researchers to develop revolutionary submarine hull designs that<br />
significantly improved speed and maneuverability and reduced underwater noise<br />
effects. The same technical resources were tapped to improve the nuclear reactor<br />
technologies originally conceptualized, developed, and manufactured by private<br />
firms.<br />
Named after its first director, the David Taylor Model B<strong>as</strong>in w<strong>as</strong> set up<br />
by the Bureau of Construction and Repair at the W<strong>as</strong>hington Navy Yard in<br />
1898. After decades of steady growth that matched the Navy’s rapid expansion,<br />
the Navy built a larger and more modern model b<strong>as</strong>in in nearby Carderock,<br />
Maryland. Construction of the towing tanks, test and evaluation laboratories,<br />
and other support facilities began in 1937, and the site became fully operational<br />
in 1940. 78 Throughout this period, engineers and scientists at the b<strong>as</strong>in applied<br />

<strong>as</strong>semblies w<strong>as</strong> all that remained of what had been an extensive propulsion program that began at the<br />
station in 1946. That year, engineers began working on a closed-cycle submarine power plant fueled by<br />
hydrogen peroxide. For nearly a decade, development of improved versions of the “Walters” engine (named<br />
for its German inventor) moved forward, but, advanced <strong>as</strong> this technology w<strong>as</strong>, it could not compete with<br />
nuclear power. In 1954, just before the first nuclear-powered submarine, the Nautilus, began sea trials, the<br />
bureau permanently shut down Engineering Experiment Station’s engine development program. Ibid., 241,<br />

77 Although they played a steadily diminishing role in new ship construction after World War II, the<br />
Navy’s shipyards actively participated in the shift from conventional to nuclear propulsion. The Electric<br />
Boat Division of the General Dynamics Corporation manufactured most of the Navy’s nuclear submarines,<br />
but the Navy built ten, beginning with the Swordfish in 1957, were built at the Portsmouth Naval Shipyard<br />
in New Hampshire. By the early 1960s, Portsmouth had become a fully integrated nuclear submarine<br />
shipyard, capable of performing construction, overhauls, and repairs. Shiman, Forging the Sword, 62.<br />
