Definition

Noun: * An aircraft designed and built using specialized technologies to make it difficult to detect by radar, infrared, acoustic, and other sensing methods. The primary goal is to reduce its radar cross-section (RCS) and other observable signatures.

Usage

• The term "stealth aircraft" refers specifically to the vehicle itself. It is a compound noun where "stealth" functions as an adjective describing the type of aircraft.
• It is used in military and aviation contexts to describe advanced combat planes.

Examples

• The stealth aircraft conducted a reconnaissance mission deep inside enemy territory without being detected.
• Developing and maintaining a fleet of stealth aircraft requires a significant budget and advanced technical expertise.
• The F-117 Nighthawk was one of the first operational stealth aircraft.

Advanced Usage

• "Stealth technology": Refers to the suite of techniques (radar-absorbent materials, specific shaping, etc.) used to create a stealth aircraft, not the aircraft itself.
  • The new fighter jet incorporates the latest stealth technology.
• "Low-observable aircraft": A more technical synonym often used in professional contexts.

Variants and Related Words

• Stealth bomber (n): A type of stealth aircraft designed primarily for long-range bombing missions (e.g., B-2 Spirit).
• Stealth fighter (n): A type of stealth aircraft designed for air-to-air combat and multi-role missions (e.g., F-22 Raptor, F-35 Lightning II).
• Stealthiness (n): The quality of being stealthy or difficult to detect.

Synonyms

• Low-observable aircraft
• Radar-evading aircraft

Related Concepts (Not Synonyms)

• Radar cross-section (RCS): A measure of how detectable an object is by radar; stealth aircraft are designed to have a very low RCS.
• Signature reduction: The overall process of minimizing all detectable signatures (radar, infrared, visual, acoustic).

Noun

1. an aircraft designed in accordance with technology that makes detection by radar difficult
