The Golden Gate is an art deco suspension bridge that stretches across San Francisco Bay and is one of the most enduring symbols of the city. Its construction arose from the need to get from San Francisco to Marin County, California and the ferry traffic in San Francisco Bay had become just too heavy. Construction on the Golden Gate Bridge began in 1933, and was completed in 1937.
The San Francisco cable car system is the world's last manually operated system in the US and is among the most famous tourist attractions in the city along with Alcatraz Island and Fisherman's Wharf. Cable cars operate on two routes from downtown near Union Square to Fisherman's Wharf and a third route along California Street.
Is an American third-generation main battle tank that entered service in 1980. It features a powerful turbine engine, sophisticated composite armor, and separate ammunition storage in a blow-out compartment for crew safety. Weighing nearly 62 metric tons, it is one of the heaviest battle tanks in service.
The Sherman Tank was the primary tank used by the United States during World War II. The tank was named after Union General William Tecumseh Sherman. Production exceeded 50,000 units. Only the Soviet T-34 tank was produced in larger numbers during World War II. Though it was wholly inadequate against the heavier armed 56 ton German Tiger I and the 72 ton Tiger II, mobility, mechanical reliability and sheer numbers helped offset their disadvantages strategically.
This German tank was the most powerful tank in the world when it was introduced in August 1942. The 88mm gun was extremely powerful and the heavy armor made it almost impervious to attack. The success of the Tiger was so profound, that no allied tank dared to engage it in open combat. This psychological fear soon became to be known as "Tigerphobia".
The Chi Ha tank was built by Mitsubishi and designated the CHI-HA. It used the Mitsubishi air-cooled 170 horsepower diesel engine and was regarded as the best tank that Japan had produced during World War II. The main armament consisted of a single 57mm gun mounted in the turret and supported by two 7.7mm self-defense machine guns.
