America's Stealth F-35 Fighter vs. the A-10 Warthog: Who Wins in a Fight?
A showdown is coming.
Will the F-35s current and future line up of weapons, coupled with its sensors and ISR technologies enable the aircraft to out-perform the A-10 warthog when it comes to Close Air Support Missions.
Flying close to ground troops in combat in hostile and high-threat conditions requires a host of unique attributes for an aircraft -- such as flying slow and low to the ground, absorbing some degree of small arms fire and having an ability to quickly maneuver in response to fast-changing ground combat conditions.
These, and many more, are among factors now being analyzed as proponents of both the A-10 Warthog and F-35 Joint Strike Fighter assess their respective abilities to perform the crucial and highly valued Close Air Support mission. The Pentagon and the Air Force are now conducting a thorough examination of each plane's capability for this role - including extensive analysis, simulated tests, flights of both aircraft under combat-like conditions and a range of tests, Air Force and Pentagon officials have explained. While many of the details of the ongoing evaluation are not now being discussed publically, the results are expected to bear prominently upon the visible ongoing debate regarding the future mission scope of both the A-10 and the F-35. The Air Force has been working on a formal Analysis of Alternatives designed to address the issue.
While the cherished A-10 is unambiguously combat-tested in the role of Close Air Support, some F-35 advocates have mused that the JSF sensors, maneuverability, high-tech computers, 25mm canon and arsenal of weapons just might better position the 5th generation aircraft for the mission; at the same time, the A-10s titanium frame, built-in redundancy, famous nose-aligned 30mm cannon and wide-ranging precision-weapons envelope make clearly make it the best choice for close air support.
Sure enough, the A-10s performance against ISIS, Congressional lobby and broad adoration among ground troops are among the many factors believed to have influenced the Air Force's current plan to both extend the life of the current A-10 and also explore requirements options for a future Close Air Support platform. Air Force officials have told Scout Warrior the ongoing requirements and analysis procedure is looking at three options - upgrading the existing A-10 airframe, using the best available commercial-off-the shelf aircraft, or simply engineering an building a newly designed A-10-like Close Air Support airplane.
Many A-10 proponents are convinced that there is no other plane capable of succeeding with the highly-dangerous, revered and essential Close Air Support Mission. Nevertheless, the Air Force does plan to use the emerging F-35 for Close Air Support moving into the next decade. In addition, F-35 advocates argue that the stealth aircraft's speed, maneuverability and high-tech weapons and sensors give the F-35 a decisive Close Air Support advantage.
A recent report in Military.com says the Pentagon has been directed by Congress to conduct a series of continued A-10 vs. F-35 weapons tests into next year, a development which could very well lead to an official "fly-off" between the two.
In the meantime, the F-35 weapons integration including live fire drops, weapons separation assessments and modifications for future munitions adaptions is progressing as well alongside the existing F-35/A-10 analysis.
The aircraft has already demonstrated an ability to fire an AMRAAM (Advanced Medium Range Air to Air Missile), JDADM (Joint Direct Attack Munition) or GBU 12 (laser-guided aerial bomb), and AIM 9X Sidewinder air-to-air missile.
So-called "Block 3F" software for the F-35 increases the weapons delivery capacity of the JSF as well, giving it the ability to drop a Small Diameter Bomb and 500-pound JDAM.
By the early 2020s, the F-35 is slated to be configured with a next-generation Small Diameter Bomb II.
As a multi-role fighter, the F-35 is also engineered to function as an intelligence, surveillance and reconnaissance platform designed to apprehend and process video, data and information from long distances. Some F-35 developers have gone so far as to say the F-35 has ISR technologies comparable to many drones in service today that are able to beam a “soda straw” video view of tactically relevant combat locations in real time.
Built-in ISR is an asset which could have the effect of greatly helping close-air-support efforts.
Also, F-35 advocates reiterate that the airplane's high-tech Electro-Optical Targeting System and 360-degree sensors Distributed Aperture System will give the newer aircraft an uncontested combat and close-air-support ability. The F-35s so-called computer-enabled "sensor fusion" might enable it to more quickly ascertain and destroy moving targets by gathering, integrating and presenting fast-changing combat dynamics and circumstances.
Finally, the F-35's stealth configuration and speed is expected to better enable it to evade air defenses and move closer to emerging ground-targets in many instances -- and its air-to-air ability will enable the aircraft to respond to potential air-threats which could appear in the course of a ground-support mission.
AIM-9X Sidewinder Missile
The F-35 Joint Strike Fighter fired an AIM-9X Sidewinder infrared-guided air-to-air missile for the first time earlier this year 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 facilities further development of an ability to fire the weapon “off-boresight,” 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.
“If you think if 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, told Scout Warrior.
The AIM-9X, he described, incorporates an agile thrust vector controlled airframe and the missile’s high off-boresight capability can be used with an advanced helmet (or a helmet-mounted sight) for a wider attack envelope.
“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 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. "The missile also has proven capability in air-to-surface and demonstrated capability in surface-to-air missions."
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, Justus added.
"The AIM-9X missile has been acquired by twenty international partners. It is configured for easy installation on a wide variety of modern fighter aircraft and we are excited to complete this milestone of the first AIM-9X live fire from the F-35 as we progress through the aircraft/missile integration activities," he said.
Weapons integration for the F-35 is designed to evolve in tandem with software advances for the aircraft, described as “increments.” Each increment, involving massive amounts of lines of computer code, improves the platform’s ability to integrate, carry and fire a wider range of weapons.
Block 2B, for example, is already operational and builds upon the enhanced simulated weapons, data link 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 (Joint Direct Attack Munition) or GBU 12 (laser-guided aerial bomb), JSF program officials have said.
The next increment, Blocks 3i will increase the combat capability even further and Block 3F will bring a vastly increased ability to suppress enemy air defenses.
The Air Force plans to reach operational status with software Block 3i in 2016. Full operational capability will come with Block 3F, service officials said.
Block 3F will increase the weapons delivery capacity of the JSF as well, giving it the ability to drop a Small Diameter Bomb, 500-pound JDAM and AIM 9X short-range air-to-air missile, Air Force officials said.
F-35 25mm Gatling Gun:
Last Fall, the Pentagon’s F-35 Joint Strike Fighter completed the first aerial test of its 25mm Gatling gun embedded into the left wing of the aircraft, officials said.
