When Looks Can Kill

Ben Sullivan writes "From the Los Angeles Times: "Test pilots here are flying with sophisticated helmets, resembling a bug's eye, that allow them to aim their weapons and sensors simply by looking at potential targets on the ground or in the air. The helmets, when coupled with a highly maneuverable new missile that is close to deployment, would enable fighter pilots to look over their shoulders and fire instantly at targets, a feat that until now has been matched only in science fiction movies." Development was done by San Jose-based Vision Systems International, a joint venture of defense electronics maker Rockwell Collins Inc. and Israeli's Elbit. Raytheon makes the sharp-turning AIM-9X missile."

The problem with swiveling your launch rails is that the airstream does not swivel too. When your aircraft is flying 500 knots, and you try to turn your missile to, say, 90 degrees off the heading angle and launch the missile, the missile will immediately begin tumbling and be utterly uncontrollable. You might be able to make a missile that could be launched successfully at 90 degrees, but that design would not work for 120 degrees. Or zero degrees.

In other words, I would argue that your conclusion is erroneous. Making a missile turn tightly is accomplished with thrust vectoring and other clever aerodynamic tricks. Doing as you suggest would take, well, antigravity, I think. : )

In order to successfully design a high-speed aircraft, it's very important to know which direction it is going to fly. There are, to date, exactly zero exceptions to this rule.
