now that 12 F-35A’s have deployed to Japan for a six-month rotation, service officials said.

While service officials describe the move as a routine deployment, called a Theater Security Package, the current tensions with North Korea are by no means lost on the Air Force and other Pentagon planners – who are preparing to demonstrate F-35 power, technology and combat readiness in a series of upcoming exercises.

Pacific Air Forces is now finalizing plans for a wide range of F-35A multi-national collaborative  training events which will, without question, seek to demonstrate possible coordinated attack options using the stealth aircraft, if ordered, over the Korean peninsula.

The 12 F-35s, now based at Kadena Air Base, Japan, arrived from Utah’s 34th Fighter Squadron, Hill Air Force Base, officials with Pacific Air Forces said in a statement.

While Marine Corps F-35B aircraft have been deployed to Japan for months, this new deployment is the first US Pacific Command operational tasking for the Air Forces’ F-35A; it is designed to build upon the F-35s debut in the Indo-Asia-Pacific at the Seoul International Aerospace & Defense Exhibition earlier in November, service officials said.

"The F-35A is operational and combat ready, and this F-35 theater security package to the Pacific Command area of responsibility is further proof of the Air Force's capability to deploy the world's most lethal fighter anywhere on the planet,” Air Force spokesman Capt. Mark Graff told Scout Warrior.

Interoperability will be a key focus of upcoming exercises, Graff said – a comment of particular relevance in light of the fact that both Japan and South Korea are F-35 Foreign Military Sales customers; Japan already has an F-35 and deliveries to South Korea are slated for 2018.

Next-generation sensors, data-links and long-range targeting technology – engineered to work in tandem across a fleet of aircraft -  are precisely the kinds of interoperability demonstrations likely to be explored. In fact, given the F-35’s Distributed Aperture System sensor (DAS), an array of six cameras covering 360-degrees around the aircraft, and the F-35s long-range Electro-Optical Targeting Systems – the aircraft is uniquely suited for ISR and data-sharing missions alongside more traditional fighter jet operations.  

The DAS includes precision tracking, fire control capabilities and the ability to warn the pilot of an approaching threat or missile.

The F-35s Electro-Optical Targeting System, or EOTS, combines forward-looking infrared and infrared search and track sensor technology for pilots – allowing them to find and track targets before attacking with laser and GPS-guided precision weapons.

Although North Korea’s Air Force is reported to be both largely antiquated and technologically obsolete, they do have fighters which could in some instances require air-to-air combat from a US F-35 or F-22.

An assessment of North Korean fighter aircraft appeared in The National Interest as follows:

“Among the most antiquated and obsolete aircraft in the North Korean air force is the Shenyang J-5, a Chinese copy of the 1950s-era Mikoyan Gurevich MiG-17 Fresco. North Korea is thought to possess roughly 106 of the antiquated fighters. Another antique fighter in the North Korean inventory is the Shenyang J-6, a Chinese derivative of the Mikoyan Gurevich MiG-19 Farmer. The North Koreans have roughly 97 of the obsolete supersonic fighters,” the report states. (Read The National Interest ReportHERE)

North Koreas is also known to have advanced air defense weapons, a scenario quite likely to necessitate the use of stealth aircraft. Also, an F-35’s full-compliment of air-to-air weapons, long range sensors and dogfighting maneuverability could also position the aircraft for air combat should that be necessary.

The Air Force, quite expectedly, did not make specific comments about the North Korean threat and its possible relationship to upcoming exercises. However, Pentagon leaders have consistently said current policy requires that North Korea irreversibly de-nuclearize. As part of this strategic equation, it is certainly not an exaggeration to say the F-35’s presence in Asia near the Korean Peninsula could be intended to send an unmistakable message to North Korea.

Furthermore, while much has been made of North Korea’s mobile missile launchers and arsenal of conventional ballistic missiles able to threaten South Korea and Japan, it is also true the that F-35 was specifically engineered to recognize and destroy far-away land based weapons launchers. Therefore, in addition to land-based defenses such as Patriot and THAAD or ship-based SM-6s, stealth air power in the form of F-35s could prove instrumental in any kind of US attack on North Korea.  In particular, the F-35A is able to fire laser-guided precision weapons such as the GBU-54 which is engineered to track and destroy mobile targets such as mobile missile launchers on the move. 

Such strategic questions now lodge themselves within the sphere of potential contingencies, as the Pentagon has said very little about what a military operation against North Korea would look like; senior DoD officials have, however, been very clear that there is indeed a military option.  Given this, it is tough to imagine any kind of military attack not drawing upon the F-35 for air-ground attacks or sensor, datalink and ISR-kinds of missions in an environment where stealth technology is likely necessary.  These possibilities underscore the importance of an anticipated US and allied show of F-35 combat force in the region through multi-national exercises.

The Air Force has more than 120 F-35As in its inventory, Graff added.

F-35 Preparations for Deployment

The Air Force has spent much time over the last few years to train and prepare F-35 pilots for these kinds of anticipated deployments.

In one instance several years ago, Air Force F-35A Joint Strike Fighters coordinated close air support with Navy SEALs, trained with F-15Es and A-10s, dropped laser-guided bombs and practiced key mission sets and tactics in Idaho as part of initial preparations for deployment. This “mini-deployment” was designed to set the stage for various operational scenarios.

During this exercise, F-35s dropped 30-bombs comprised of 20 laser-guided bombs and 10 JDAMS.

During these exercises at Mountain Home AFB, the F-35A also practiced coordinating communications such as target identification, radio and other command and control functions with 4th-generation aircraft such as the F-15.

These training exercises in Idaho, were also the first “real” occasion to test the airplane’s ability to use its computer system called the Autonomic Logistic Information System, or ALIS. The Air Force brought servers up to Mountain Home AFB to practice maintaining data from the computer system.

F-35A "Sensor Fusion"

The computer system is essential to what F-35 proponents refer to as “sensor fusion,” a next-generation technology which combines and integrates information from a variety of sensors onto a single screen. As a result, a pilot does not have to look at separate displays to calculate mapping information, targeting data, sensor input and results from a radar warning receiver.

“Fusion” technology allows F-35A pilots to process information and therefore make decisions faster than a potential enemy. He explained how this bears upon the historic and often referred to OODA Loop – a term to connote the Observation Orientation, Decision, Action cycle that fighter pilots need to go through in a dogfight or combat engagement in order to successfully destroy the enemy. The OODA-Loop concept was developed by former Air Force strategist Col. John Boyd; it has been a benchmark of fighter pilot training, preparation and tactical mission execution.

Also, the F-35 is able to fire weapons such as the AIM-9X Sidewinder air-to-air missile “off boresight,” meaning it can destroy enemy targets at different angles of approach that are not necessarily directly in front of the aircraft.

The F-35 is also engineered with an Active Electronically Scanned Array Radar which is able to track a host of electromagnetic signals, including returns from Synthetic Aperture Radar, or SAR. SAR paints a picture of the contours of the ground or surrounding terrain and, along with Ground Moving Target Indicator, or GMTI, locates something on-the-move on the ground and airborne objects or threats.

3F Software Operational

The Air Force is now in the process of operationalizing the F-35’s latest “3F” software iteration, a development which integrates additional technology and equips the stealth aircraft with a wider range of weapons such as the Small Diameter Bomb and AIM-9X, service leaders said.

After experiencing some challenges during developmental testing, the 3F software drop is now improved and sharpened up for delivery, senior Air Force officials said.

Many of the JSF’s combat capabilities are woven into the F-35s combat capabilities are woven into developmental software increments or “drops,” each designed to advance the platform’s technical abilities. There are more than 10 million individual lines of code in the JSF system.

Block 3F increases the weapons delivery capacity of the JSF as well, giving it the ability to drop a Small Diameter Bomb, 500-pound JDAM (Joint Direct Attack Munition) and AIM-9X short-range air-to-air missile, service officials explained.


Last year, in preparation for 3F becoming operational, an Air Force  F-35 Joint Strike Fighter fired an AIM-9X Sidewinder infrared-guided air-to-air missile for the first time over a Pacific Sea Test Range, Pentagon officials said.

The F-35 took off from Edwards Air Force Base, Calif., and launched the missile at 6,000 feet, an Air Force statement said.

Designed as part of the developmental trajectory for the emerging F-35, the test-firing of the AIM-9X was intended to further the missile's ability to fire “off-boresight." This is described as an ability to target and destroy air to air targets that are not in front of the aircraft with a direct or immediate line of sight, Pentagon officials explained.

Previous test data and observers have confirmed the F-35 identified and targeted the drone with its mission systems sensors, passed the target ‘track’ information to the missile, enabled the pilot to verify targeting information using the high off-boresight capability of the helmet mounted display and launched the AIM-9X from the aircraft to engage the target drone, a statement from the Pentagon's Joint Strike Fighter Program Office said. 

“If you think of a boresight in terms of a firearm… that’s the adjustments made to an optical sight, to align the barrel of a firearm with the sights.  If you think of it in aircraft terms… traditionally air-to-air missiles are fired at targets in front of the them,” Joint Strike Fighter Program Office spokesman Joe DellaVedova, previously told Scout Warrior in an interview.

The AIM-9X, he described, incorporates an agile thrust vector controlled airframe.

“For example, instead of having to position the aircraft directly in front or behind the enemy fighter… a high off-boresight weapon enables the pilot to just look to the left, right or up and down to engage a target, fire it and the missile locks on for the kill,” he explained.  

The AIM-9X is an Air Force and Navy heat-seeking infrared missile.

The AIM-9X missile, which can also be fired at surface-to-air and air-to-surface, is currently in use on a number of existing fighter aircraft such as the Air Force’s F-15E and F-16 and the Navy’s F-18 Super Hornet.

Engineered by Raytheon, the newest AIM-9X Block II weapons are built with a redesigned fuse for increased safety and a lock-on-launch capability. The missile is also configured with a data link to support what’s called “beyond visual range” engagements, meaning targets at much farther ranges picked up by sensors or early warning radar. This could provide a fighter jet with an ability to destroy enemy targets in the air while remaining at a safer stand-off distance less exposed to hostile fire.

"The AIM-9X Sidewinder is an infrared-guided, air-to-air missile employing a focal plane array sensor for unparalleled target acquisition and tracking, augmented by jet vane control technology for extreme maneuverability against a variety of high performance threats,” Mark Justus, Raytheon AIM-9X program director, told Scout Warrior in a written statement last year. "The missile also has proven capability in air-to-surface and demonstrated capability in surface-to-air missions." 

Immediately prior to the test-launching of the AIM-9X, a test pilot employed an internally carried AIM-120C missile against another target drone. This target was beyond visual range and the AIM-120C was given a successful self-destruct signal right before target impact, Pentagon statements said.

The AIM-9X Block II is the current version of the AIM-9 Sidewinder short range missile family in use by more than 40 nations throughout the world, developers said.

4th Software Drop

The 3F software drop is preceded by earlier increments, each one bringing new technical integration to the aircraft.

Block 2B built upon the enhanced simulated weapons, datalink capabilities and early fused sensor integration of the earlier Block 2A software drop. Block 2B enables the JSF to provide basic close-air support and fire an AMRAAM (Advanced Medium Range Air-to-Air Missile), JDAM or GBU-12 (laser-guided aerial bomb), JSF program officials said.

Following Block 2B, Block 3i increases the combat capability even further, and Block 3F brings a vastly increased ability to suppress enemy air defenses.

Called 3F, the service is already working on a 4th drop to be ready by 2020 or 2021. Following the drop of 3F, the aircraft will incorporate new software drops in two-year increments in order to stay ahead of the threat.

The first portion of Block 4 software funding, roughly $12 million, arrived in the 2014 budget, Air Force officials said.

Block 4 will include some unique partner weapons including British weapons, Turkish weapons and some of the other European country’s weapons that they want to get on their own plane, service officials explained.

Block 4 will also increase the weapons envelope for the US variant of the fighter jet.  A big part of the developmental calculus for Block 4 is to work on the kinds of enemy air defense systems and weaponry the aircraft may face from the 2020’s through the 2040’s and beyond.

In terms of weapons, Block 4 will eventually enable the F-35 to fire cutting edge weapons systems such as the Small Diameter Bomb II and GBU-54 – both air-dropped bombs able to destroy targets on-the-move.

The Small Diameter Bomb II uses a technology called a tri-mode seeker, drawing from infrared, millimeter wave and laser-guidance. The combination of these sensors allows the weapon to track and eliminate moving targets in all kinds of weather conditions.
