stealth technology

The use of advanced design and specialized materials to make an aircraft difficult or even impossible to detect by radar.

Note

Stealth aircraft were used for the first time in the Persian Gulf War, where they were highly successful.

Note

The term is now used to refer more generally to something that remains hidden or unknown: “This is a stealth proposal: no one knows what it means.”
