These are the best "unseen" military assets and not all are in the air.
Stealth, or the idea of reducing the ability of the enemy to detect a weapon, has been around since the first caveman sewed a pocket into his clothing and hid a rock in it.
Thousands of years later, with the ability to detect objects on the ground, in the air and at sea using electromagnetic radiation, hiding weapons in plain sight has become much harder. The idea of making an aircraft invisible to radar waves was not pursued as the properties of radar with regards to object shape were not fully understood.
Pyotr Ufimtsev, a Russian physicist, published a number of papers [3] on predicting the reflection of electromagnetic waves—radar waves. The Soviet Union, not understanding the gravity of his work, translated many of them into English.
