In the Gathering Storm expansion, the Jet Bomber requires 1 Aluminum to train and 1 Aluminum per turn to maintain.
Jet Bombers are invaluable units in Information Era warfare. Using normal bombing runs, Jet Bombers can quickly wear down a city's defenses, allowing the city to be taken easily. If necessary, a Jet Bomber is also capable of performing a Nuclear or Thermonuclear Strike, which will instantly destroy the defenses of any cities caught within the blast radius.
Civilopedia entry Edit
As fighters got faster and more lethal, for a brief period jet bombers were considered necessary by Cold War air forces … until intercontinental ballistic nuclear missiles promised the ability to rain destruction on distant cities with less fuss. The United States designed the XB-70 Valkyrie, for instance, to carry nuclear warheads across the pole to Russia – only two were ever built. The B-1 Lancer was somewhat more successful; with a speed of Mach-2 it could (hopefully) outrun the nuclear blast so the crew might survive – about 100 of the B-1B version were put in service as “low-level penetrators.” But in general, the old B-52s and Soviet Tu-95 series worked just as well (although their attack would be a one-way trip), and were a lot cheaper. In modern air forces, the distinctions between bombers, fighter-bombers and fighters have blurred considerably, such that most aircraft in service today could be considered “jet bombers.”
The Jet Bomber's model is based on the B-52 Stratofortress, an American long-range bomber built by Boeing after World War II.
