The British had begun building a naval base at Singapore in 1923, partly in response to Japan's increasing naval power. A costly and unpopular project, construction of the base proceeded slowly until the early 1930s when Japan began moving into Manchuria and northern China. A major component of the base was completed in March 1938, when the King George VI Graving Dock was opened; more than 300 meters in length, it was the largest dry dock in the world at the time. The base, completed in 1941 and defended by artillery, searchlights, and the newly built nearby Tengah Airfield, caused Singapore to be ballyhooed in the press as the "Gibralter of the East." The floating dock, 275 meters long, was the third largest in the world and could hold 60,000 workers. The base also contained dry docks, giant cranes, machine shops; and underground storage for water, fuel, and ammunition. A self-contained town on the base was built to house 12,000 Asian workers, with cinemas, hospitals, churches, and seventeen soccer fields. Above-ground tanks held enough fuel for the entire British navy for six months. The only thing the giant naval fortress lacked was ships.

The Singapore naval base was built and supplied to sustain a siege long enough to enable Britain's European-based fleet to reach the area. By 1940, however, it was clear that the British fleet and armed forces were fully committed in Europe and the Middle East and could not be spared to deal with a potential threat in Asia. In the first half of 1941, most Singaporeans were unaffected by the war on the other side of the world, as they had been in World War I. The main pressure on the Straits Settlements was the need to produce more rubber and tin for the Allied war effort. Both the colonial government and British military command were for the most part convinced of Singapore's impregnability.

Even by late autumn 1941, most Singaporeans and their leaders remained confident that their island fortress could withstand an attack, which they assumed would come from the south and from the sea. Heavy fifteen-inch guns defended the port and the city, and machine-gun bunkers lined the southern coast. The only local defense forces were the four battalions of Straits Settlements Volunteer Corps and a small civil defense organization with units trained as air raid wardens, fire fighters, medical personnel, and debris removers. Singapore's Asians were not, by and large, recruited into these organizations, mainly because the colonial government doubted their loyalty and capability. The government also went to great lengths to maintain public calm by making highly optimistic pronouncements and heavily censoring the Singapore newspapers for negative or alarming news. Journalists' reports to the outside world were also carefully censored, and, in late 1941, reports to the British cabinet from colonial officials were still unrealistically optimistic. If Singaporeans were uneasy, they were reassured by the arrival at the naval base of the battleship Prince of Wales, the battle and four destroyers cruiser Repulse, on December 2. The fast and modern Prince of Wales was the pride of the British navy, and the Repulse was a veteran cruiser. Their accompanying aircraft carrier had run aground en route, however, leaving the warships without benefit of air cover (See Historical Development , ch. 5).
