Ogeechee River

This chapter describes William T. Sherman’s approach march to Fort McAllister. The March to the Sea might be over, but Sherman had not yet reached the sea. He had managed to cross the Ogeechee River thanks to the reconstruction of King’s Bridge, but he still faced two problems. First, he needed to make contact with the Union fleet. Second, he still needed to seize Savannah, a risky operation that needed to be completed swiftly. It is true that Sherman encountered weak opposition and that the March had not pulled significant Confederate reinforcements to Savannah. Nonetheless, Sherman lacked the equipment for a prolonged siege and might yet be seriously embarrassed. The fall of Fort McAllister permitted Sherman to concentrate his energies on establishing contact with the US Navy. Once contact with the US Navy had been firmly established, it brought some unexpected pleasures. The chapter then looks at the interactions between Sherman and the Secretary of War, Edwin M. Stanton.

Polysiloxane coatings are the most recent high performance coatings developed to take advantage of the heat and oxidation resistant properties of silicone-based materials. Commercially available polysiloxane coatings predominately consist of organic-inorganic siloxane materials (though some pure siloxane materials are available). Recently, the US Navy has approved polysiloxane coatings as “High Durability” in their specification for exterior weather resistant coatings (MIL-PRF-24635 Type V and VI). Navy approval comes after over 20 years of industry development of polysiloxane coatings for high performance industrial and marine applications, yet issues remain with their cost-effective implementation in the Navy fleet. This paper will review experiences of the offshore and marine industry with polysiloxane coatings and provide an update on the Navy adoption of the technology.

A Duet for Sailors and Pansies: Queer Archival Work and Male Same-Sex Dancing in Follow the Fleet (1936) and Other Depression-Era Films

Depression Era

This chapter explores a queer all-male dance lesson for partnered sailors in the Fred Astaire–Ginger Rogers musical Follow the Fleet (1936), using archival research (scripts, Production Code Administration records) and comparative textual and contextual analysis. It raises the queerness of Rogers and Astaire before exploring two intersecting axes. The association of sailors with queer behavior and effeminate “pansies” occurs in military scandals, paintings, and Depression-era Hollywood films, including Sailor’s Luck and Son of a Sailor (both 1933). The queerness of male same-sex dancing arises in ballet and in film, including Suicide Fleet (1931). Various institutions criticized or attempted to censor such representations, but they also found acceptance. The US Navy, for example, wanted the comical dance lesson removed from Fleet; instead, it was only rewritten, suggesting the inability to remove queerness from culture and its essential role in mass entertainment.

Major Loss

After almost a century the US Navy has reintroduced tumblehome into the design of naval combatants. This paper discusses some of the reasons tumblehome was originally designed into ships and why it served it owners well for many centuries. The transition from sail to steam power a little over a century ago led to a variety of problems with the combatant ships designed with tumblehome where the lack of damage stability caused a major loss of life as these ships sank so quickly. During World War I ships designed with tumblehome fell out of favor and some of the ships were actually modified to remove the tumblehome from the design. These changes in the design of tumblehome ships are discussed in this paper.

Design Speed

The US Navy is currently considering the introduction of a Flight III variant beginning with DDG-123 in Fiscal Year 2016. The new design incorporates a new combat system and associated power and cooling upgrades. The overall system improvements increase the payload of the ship and the resulting increased displacement has a negative impact on the service life allowance for range, fuel consumption and sea-keeping characteristics. The present objective is to increase the hull displacement without resistance and sea-keeping penalty and with minimal modifications to the baseline DTMB-5415 design (open literature surrogate of the existing DDG-51 hull form) by using retrofitted blisters in the form of side hull expansions and a bow-bulb. The investigation makes use of high-performance CFD computing for analysis of wave cancellation mechanisms. A candidate modified 5415 design with both blisters and bow bulb shows a resistance reduction of ~11% w.r.t.the baseline 5415 in the design speed range of 15-19 knots, even though the displacement is increased by 8%, such that the transport factor is increased by 19%.

Do So

In January-February 1939, a secret German expedition visited Dronning (or Queen) Maud Land, Antarctica, apparently with the intention inter alia of establishing a base there. Between 1943 and 1945 the British launched a secret wartime Antarctic operation, code-named Tabarin. Men from the Special Air Services Regiment (SAS), Britain's covert forces for operating behind the lines, appeared to be involved. In July and August 1945, after the German surrender, two U-boats arrived in Argentina. Had they been to Antarctica to land Nazi treasure or officials? In the southern summer of 1946–1947, the US Navy appeared to ‘invade’ Antarctica using a large force. The operation, code-named Highjump, was classified confidential. In 1958, three nuclear weapons were exploded in the region, as part of another classified US operation, code-named Argus. Given the initial lack of information about these various activities, it is not, perhaps, surprising that some people would connect them to produce a pattern in which governments would be accused of suppressing information about ‘what really happened’, and would use these pieces of information to construct a myth of a large German base existing in Antarctica and of allied efforts to destroy it. Using background knowledge of Antarctica and information concerning these activities that has been published since the early 1940s, it is demonstrated: that the two U-Boats could not have reached Antarctica; that there was no secret wartime German base in Dronning Maud Land; that SAS troops did not attack the alleged German base; that the SAS men in the region at the time had civilian jobs; that Operation Highjump was designed to train the US Navy for a possible war with the Soviet Union in the Arctic, and not to attack an alleged German base in Antarctica; and that Operation Argus took place over the ocean more than 2000 km north of Dronning Maud Land. Activities that were classified have subsequently been declassified and it is no longer difficult to separate fact from fancy, despite the fact that many find it attractive not to do so.
