This Is What An F-35 in ‘Beast Mode’ Looks Like

F-35 Beast Mode

This is the first time Australian F-35As have carried a full load of external bombs. *** Local Caption *** As one of Air Force’s largest domestic training exercises for 2021, Arnhem Thunder provides Air Force with important force generation training, focusing on high end collective training and involving multiple Force Element Groups (FEGs). Operating out of Royal Australian Air Force (RAAF) Bases Darwin and Tindal, Arnhem Thunder 21 provides an excellent venue for cross-FEG interoperability, high-end air power missions as well as practicing rapid airbase activation. Exposure to large scale offensive counter air scenarios in an away-base environment is of vital importance to the training outcomes of Air Force elements. Approximately 40 aircraft and over 500 personnel from the Air Force have deployed to take part in Exercise Arnhem Thunder 21.

A pair of Lockheed Martin F-35A fighters in service with the Royal Australian Air Force (RAAF) recently operated with a full weapons load – otherwise known as “beast mode” – during a recent training flight from RAAF Darwin, as part of the Arnhem Thunder 21 exercise. The two fifth-generation combat aircraft carried four inert GBU-12 bombs under their wings, along with unspecified weapons loaded internally.

The weapons were reportedly dropped on a range.

“This design feature allows Australian F-35As to be adapted to suit the threat environment and operational requirements,” said Mathew Harper, commanding officer of 35 Sqn. “This mode would most likely be used in less contested environments where rapid employment of ordnance is prioritized over maximizing the F-35A’s stealth capabilities.”

The Multi-roles of the F-35

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.”

The different weapon layouts are meant to accommodate a range of tactical scenarios.

The “First Day of War” loadout would preserve the “stealth” configuration, and could consist of four AIM-120 AMRAAM missiles for air-to-air missions, or a mixture of four AIM-120s/GBU-31 JDAM “smart bombs,” for air-to-ground missions, all of which would be loaded into the F-35’s internal armaments bay. As the name implies, stealth loadouts are designed to minimize radar cross-section and to maintain low observability (LO) when the enemy’s anti-air systems are operating at full capacity.

As an adversary’s hostile anti-air systems – including sensors, air defense missiles, gun systems, and even enemy aircraft – are eliminated, and the conflict enters into the “Third Day of War,” the loadout would change accordingly. When it is determined that the F-35 no longer needs to rely on its stealth and LO for survivability the “beast mode” comes into play as the F-35 then deploys externally-mounted weapons with a larger radar footprint.

The weapons loadout is significantly larger.

In stealth mode, the F-35 can carry 5,700 lbs internally, while in “beast mode” it can carry a full 22,000 lbs, of both air-to-air and air-to-ground munitions.

Advance Australia Fair

The RAAF’s F-35As achieved initial operational capability (IOC) in December 2020, and it had been a long-stated goal for the RAAF. The IOC milestone included the ability to employ weapons such as the Raytheon AIM-120 AMRAAM medium-range air-to-air missile, AIM-9X Sidewinder missile, the Joint Direct Attack Munition, Small Diameter Bombs, and the type’s internal 25mm cannon.

According to Flight Global, Cirium fleets data shows that the RAAF has thirty-seven in-service F-35As out of a total planned seventy-two that had been ordered by the government in Canberra with the last one is projected to be delivered to Australia by 2024. The RAAF currently maintains a joint pilot training and maintenance presence at Luke Air Force Base (AFB), Arizona where RAAF pilots can take part in joint training with the U.S. Air Force pilots.

Australia announced in 2009 that it had selected the conventional takeoff and landing (CTOL) F-35A Lightning II to replace its F/A-18 Hornet fighter fleet.

    I can’t believe people are writing this crap.

    Back in January the Pentagon and the out going secretary of Defense labeled the F-35 a POS. One High ranking Air Force officer called it a trillion dollar flying cluster F**k.

    The reason the F15EX exists, is because the F-35 doesn’t. The F-35 is really a useless POS, that has never worked, and it never will.

    It lost its Supersonic speed, because the Air Frame can’t take the stress. The main Cannon can’t shoot straight and the barrel cracks causing the F35 to shoot itself.

    Those problems are no longer problems because the Fix for the Airframe at supersonic speed is it no longer flies supersonic speed.

    The Cannon that can’t shoot straight and cracks has been removed, no replacement. Just like the F4 Phantoms because Dogfighting was over with long range Air to Air missiles. Then the Vietnam war started and suddenly pilots didn’t have a cannon, then the F4s were all retrofitted with air to air cannon.

    It still has 15 serious design flaws and 1000’s bugs and glitches in the 8 million lines of computer code that when one bug is fixed it causes more bugs throughout the software.

    It’s taken everything the design engineers know and could figure out, just to keep it flying. Its not, and never will be what the propagandist articles, claim it is. A top of the line state of the art combat aircraft.

    Beast mode, is classic propaganda. It doesn’t carry enough weapons to matter, because of its ridiculously poor range, so more weapons to fix the deficiencies at the cost of its stealth.

    I really hope nobody has to fly this POS against a enemy better equipped then mountain boys with Aks and RPGs.

    In the top 5, of worst aircraft, ever built. .

    @ Chris – That is silly. Where do you get your “insider information?” I suspect that you’re reading all of the wrong (i.e., partisan op-ed) websites.

    The F-35 is an amazing aircraft. While it has had its problems (mostly from financial and time constraints under the Obama Administration), it has developed into an absolute beast of an aircraft.

    LOL, nice trolling, Maya Ayala. You even slipped the word beast in there. I agree where beast = POS. The USA has totally lost its way with corrupt government, endless dopey spending, engineers who are more likely ‘fungineers’ and the new mission for all agencies and military is being ‘woke.’ We’re in HUGE trouble when (not if) the next war is stirred up by the elites.
