The list of units
Stealth Bombers can do everything normal bombers can do and more. They can execute all air missions, except air superiority. Due to their stealth technology, stealth bombers are very difficult to intercept by enemy air superiority fighters, and/or SAM batteries.
A city must have oil and aluminum in its Strategic Resource to build a stealth bomber.
Concurrent with the development of a stealth fighter, aeronautical engineers began to apply stealth technology to a full-scale bomber. The B-1B bomber, which went into service in 1986 as a replacement for the B-52, incorporated some of these innovations. The radar signature of the B-1B was reduced to a mere one percent that of the B-52 due to its low cross-section and its minimal use of radar-reflective, hard-edged surfaces. Soon after the B-1B entered service, the U.S. Air Force commissioned Northrop to develop a true stealth bomber as an eventual replacement. First revealed to the public in 1988, the B-2 stealth bomber uses a flying wing design similar in shape to the F-117A stealth fighter. The flying wing design reduces the profile of the B-2 by incorporating its engines into the body of the plane. The engine exhausts and intakes are shielded to prevent infrared tracking. The B-2 also makes use of curved surfaces and radar-absorbing materials to enhance its "invisibility", and make it far less detectable than the B-1B. As of the late 1980s, it was announced that 132 B-2's would be constructed, and would enter service sometime in the 1990s.
