Stealth is a vehicle specialization in Battlefield 3. It is the air vehicle counterpart to Thermal Camo. When activated, the spotting radius for enemies is decreased, and any successful spots will disappear faster. Stealth also reduces the radius for weapon lock, protecting the user from heat-seeking weaponry. It also increases the lock on time by 35%, from 2 seconds to 2.7 seconds.

"Special plating that increases the time it takes for enemy targeting systems to lock onto you."

— In-Game description

Stealth Coating is an air vehicle specialization in Battlefield 4. It functions in a similar manner to that of the Battlefield 3 counterpart, forcing enemy combatants to take more time in acquiring a successful lock-on to the operator's vehicle. This can be useful if the player is actively performing Hit-and-Run tactics, allowing them to escape the area before a lock-on can be achieved by hostiles.

A similar specialization, Thermal Camo, is available for ground vehicles, offering the same effect.
