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 />

250–54.<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 />
