黑鸟SR-71作为世界上第一个投入运营的隐形飞机应该属于60，70年代的设计吧？

The tail of the P-530 was originally fairly conventional, with slab tailplanes mounted below mid-level. Originally, a single vertical fin was planned. The ability of the P-530 to fly at extreme angles of attack indicated that a single vertical tail would be inadequate, since it would be blanketed in the wake of the wing. To overcome this problem, the single centerline fin was replaced by twin fins, each about half as large as the original single surface, canted out at almost 45 degrees to put them in free-stream airflow. To reduce cross-coupling effects in roll, the rudders reached only halfway up the fins. In 1969, the canted fins were approximately doubled in size and moved forward to a position partially overlapping the wing. By late 1970, the tailplanes had been further enlarged and the outward cant of the fins had been reduced to only 18 degrees. At the same time, the horizontal tails were also enlarged and moved further reawards on the fuselage sides, as far aft as possible.
