Beast mode” is the ability for the F-35 to load up munitions on its external weapons pylons by sacrificing its stealth ability, while the Stealth Mode applies when the aircraft is flown with all its weapons stored in the internal weapon bays.
The Lockheed Martin-built Joint Strike Fighter was developed to be a “multi-role” stealth fighter, which in essence means that it was specifically engineered with an ability to launch massive air attacks on air-to-air and air-to-ground targets. The aircraft employs an internal weapons bay intended to enable attacks against an adversary while preserving a stealth configuration, yet can be utilized in a full-force attack by employing the external pylons as well – which has become known as its “beast mode” or “bomb truck.”
Actually, there are two ways to fly the American military’s proud fighter plane, the F-35 Lightning, developed by the Lockheed Martin company – either flown in “Stealth Mode” or Beast Mode.
This “Beat mode” refers to when the F-35 aircraft flies with a maximum payload consisting of multiple types of guided shells and smart bombs dissipating up to 10,000 kilograms in weight using external weapon bays, while compromising the aircraft’s stealth element and exposing its presence to enemy radar screens.
