F-35 preps for weapons upgrade by dropping new bombs

The F-35 will once more fireplace its 25mm gun and air-drop a number of new laser-guided bombs to organize stealth Fifth-Gen fighter for future excessive tech warfare by bettering precision-strike air assault, concentrating on and close-air-support.

The GAU-22 Gun System, Small Diameter Bomb II and GBU-38/54 are all scheduled for added floor and flight exams later this 12 months, Brandi Schiff, an official with the F-35 II Joint Program Workplace, informed Warrior in a written assertion.

The weapons, now in growth for a number of years, will construct upon the present arsenal of air-to-air and air-to-ground weapons now working on the F-35. Present manufacturing F-35s are licensed to hold Paveway IV, GBU-12 and GBU-49 laser-guided bombs, Schiff mentioned.

The Navy’s now-operational F-35C is making ready for its first deployment. Strike Fighter Squadron 147 (VFA-147), often known as the “Argonauts” based mostly at Naval Air Station Lemoore in California, is scheduled to be the primary USN F-35C squadron to make an operational deployment, Schiff mentioned.


The Air Drive’s F-35 testing, software program growth and integration for these new weapons are a key a part of an upcoming Block Four variant of the F-35 Joint Strike Fighter, an rising software program improve supposed to offer the multi-role fighter a brand new dimension of assault mission prospects, service leaders mentioned. The Block Four program brings extra weapons to the F-35, together with GBU-53 Small Diameter Bomb and GBU-54 Laser Joint Direct Assault Munition.

The four-barrel 25mm gun is designed for rapid-fire as a way to rapidly blanket an enemy with gunfire and destroy targets rapidly. The weapon is ready to fireplace 3,300 rounds per minute, in response to a press release from Normal Dynamics.

The Block Four initiative is a part of a long-range trajectory deliberate for the F-35 described by Pentagon builders as C2D2 – Steady Functionality Improvement and Supply. The concept, officers say, is to place the multi-role fighter such that it could actually constantly accommodate new weapons, stealth supplies, sensors and steering expertise as they turn out to be obtainable.

The weapons integration is according to a present Air Drive technique to expedite software program upgrades to the plane by retaining tempo with present technological change. As an alternative of relying upon pre-determined increments to be added at fastened cut-off dates usually a number of years aside, F-35 builders see the necessity for constant quick time period integration of software program enhancements as they emerge.


Small Diameter Bomb II

The SDB II, described as a key aspect of Block 4, is a brand new air-dropped weapon in a position to destroy shifting targets in every kind of climate circumstances at ranges larger than 40-miles, Air Drive and Raytheon officers mentioned.

The weapon, formally referred to as StormBreaker, has accomplished its operational drop testing and is now shifting towards integration, a Raytheon assertion mentioned.

GPS and laser-guided weapons equivalent to Joint Direct Assault Munitions have been round for many years, nonetheless, they’ve primarily been designed to be used in opposition to fastened or stationary targets.

Whereas the Air Drive at the moment makes use of a laser-guided bomb referred to as the GBU-54 in a position to destroy shifting targets, the brand new SDB II will be capable of do that at longer ranges and in every kind of climate circumstances. As well as, the SDB II is constructed with a two-way, dual-band knowledge hyperlink which permits it to alter targets or modify to totally different goal places whereas in flight, Raytheon builders informed Warrior Maven.


The Small Diameter Bomb II (SDB II), which has already accomplished a collection of wind tunnel exams, can destroy shifting targets in all climate circumstances at ranges larger than 40 miles — a Raytheon assertion mentioned.

A key a part of the SDB II is a expertise referred to as a “tri-mode” seeker — a steering system which may direct the weapon utilizing millimeter-wave radar, uncooled imaging infrared steering and semi-active laser expertise.

Raytheon weapons builders say the tri-mode seeker gives a spread of steering and concentrating on choices sometimes not used collectively in a single system. Millimeter-wave radar offers the weapon a capability to navigate by means of antagonistic climate, circumstances by which different steering methods would possibly encounter issues reaching or pinpointing targets.

​Imagining infrared steering permits the weapon to trace and hone in on warmth signatures such because the temperature of an enemy car. With semi-active laser expertise, the weapon could be guided to an actual level utilizing a laser designator or laser illuminator coming from the air or the bottom, Raytheon officers informed Warrior.


Additionally, the SBD II brings a brand new skill to trace targets in flight by means of the usage of a two-way Hyperlink 16 and UHF knowledge hyperlink, Raytheon officers mentioned.

One Raytheon SDB II developer informed Warrior in a earlier interview that “the millimeter-wave radar activates first. Then the information hyperlink offers it a cue and tells the seeker the place to open up and look. Then, the weapon can activate its IR (infrared) which makes use of heat-seeking expertise.”

The SBD II is engineered to weigh solely 208 kilos, a lighter weight than most different air-dropped bombs in order that eight of them can match on the within of an F-35 Joint Strike Fighter, Raytheon officers defined.

If weapons are stored in an inner weapons bay and never rested on an exterior weapons pod, then an plane can achieve retaining its stealth properties as a result of the shapes or contours of the weapons won’t be seen to enemy radar.


About 105 pound of the SDB II is an explosive warhead which encompasses a “blast-frag” functionality and a “plasma-jet” expertise designed to pierce enemy armor, Raytheon officers defined.


The SDB II additionally has the power to categorise targets, that means it might, for instance, be programmed to hit solely tanks in a convoy versus different shifting automobiles. The weapon can classify tanks, boats or wheeled targets, Raytheon officers added.
