内容简介：
In the twenty-first century, the U.S. military plans to increase production of unmanned aerial vehicles (UAVs) that will engage in battle with the enemy without putting human pilots in danger. This is an example of the technologies discussed in this new title about what the air force of the future might look like. In addition to describing a number of different aircraft through age-appropriate text, photographs, and illustrations, this exciting, action-packed book also speculates on top secret projects the U.S. military may be working on, known as deep black projects.
