The F-35 is one of the best stealth fighters on planet Earth - maybe the best fighter jet. And the F-35 comes with the ability to leave its stealth configuration and add on a lot more firepower. That can only mean one thing: F-35 Beast Mode. 

The F-35 is typically perceived as a graceful and refined fighter, created with advanced features emphasizing concealment and surgical precision. The common perception is grounded in truth; indeed, the F-35 is a fifth-generation stealth fighter, built to house software that enhances network connectivity and data sharing. But the common perception discredits the F-35 for its versatility – and for its ability to “roll up its sleeves.”

Remember, the F-35 is a multi-role fighter, and when prompted, can be reconfigured as a straightforward, knuckle-dragging, bomb-carrier. The reconfiguration is known as “Beast Mode.”

All Out Flight 

Designed with stealth technology, the F-35 is adept at entering contested airspace, avoiding detection, and engaging enemy targets – all before air superiority is established. Really, the F-35 is designed expressly to initially establish air superiority. And because the F-35 is designed to be stealthy, concessions were made with respect to weapons payloads. To enhance its stealth characteristics, the F-35 uses an internal weapons bay, rather than external hard points that drastically increase an aircraft’s radar cross-section. While the internal weapons bay makes for a stealthier airframe, the storage space, inside the fuselage, is limited. 

F-35 Stealth or Carry: Enter Beast Mode 

In stealth mode, when the F-35 carries weapons internally, the jet can handle just 5,700 pounds of ordinance. That breaks down to either four AIM 120 AMRAAM missiles (for air-to-air missions), or alternatively – for hybrid missions – two AMRAAMs paired with two GBU-31 JDAM bombs. That’s not very much firepower – but the concession is worthwhile to gain stealth benefits. 

However, once air superiority is established, once an enemy loses its anti-air systems such as air defense missiles and guns, sensors, interceptor aircraft, stealth mode becomes less relevant. And when stealth loses its relevance, the F-35 can enter “Beast Mode,” and use its external hard points to maximize its firepower.

In Beast Mode, the F-35 can handle four times more ordinance than when operating in stealth mode. Using the external hardpoints plus the internal weapons bay, the F-35 can carry 22,000 pounds of ordinance. That breaks down to 14 AMRAAMs and two AIM-3x Sidewinder missiles for air-to-air missiles.

Or, for hybrid missions, the jet can be outfitted with two AMRAAMs, two Sidewinders, and six JDAM 2,000-pound bombs. Indeed, the boost in firepower is significant – although, in Beast Mode, the F-35’s operational range is cut in half – to just 1,400 kilometers. 

Something may feel counterintuitive about using the F-35, a fifth-generation jet/supercomputer, as a simple bomb truck – a role that clunkier, Cold War-era aircraft, like the F-16 or B-52, are entirely equipped to handle. Yet, when you consider that the F-35 program cost taxpayers 1.7 trillion dollars, the notion of using the jet just to secure air superiority in the opening salvo of a conflict becomes offensive. 

If you’re going to spend that type of money on an airframe, you’d better milk it for all it’s worth – a sentiment that the Beast Mode configuration embodies. And for the U.S., which has a tendency to invade countries with rudimentary air defense systems – and then stick around for multi-decade occupations – the F-35 needs to be able to do more than just sneak around and wipe out air defense systems in the first few days of conflict.
