UFO Chasing an A-10 Warthog
The A-10 Thunderbolt II, affectionately known as the “Warthog,” is a singular aircraft within the United States Air Force’s fleet, designed specifically for close air support (CAS) missions. It was conceived during the Vietnam War era when the need for a robust, survivable aircraft that could effectively engage ground targets was recognized. Designed by Fairchild Republic in the early 1970s, the A-10 entered service in 1976 and has proven its worth in conflict zones from the Middle East to the Balkans, Afghanistan, and Iraq.
The A-10 Thunderbolt II, also known as the Warthog, has a maximum speed of about 439 miles per hour (or 706 kilometers per hour), or 381 knots at sea level.
One of the significant features of the A-10 is its ability to fly at slow speeds, which is crucial for a close air support aircraft as it allows the pilot more time to identify targets and carry out precision attacks. The A-10 has a stall speed (the slowest speed it can fly without stalling) of 138 miles per hour (222 kilometers per hour) with its flaps down. This allows the A-10 to fly slow and low during close air support missions, giving it a distinct advantage in its primary role.
The A-10’s distinctive design revolves around its primary weapon, the GAU-8/A Avenger 30mm cannon, one of the most powerful aircraft cannons ever flown. This seven-barreled gatling-style gun can fire depleted uranium armor-piercing shells at a rate of 3,900 rounds per minute. The aircraft was actually built around this cannon, with the gun’s massive barrel making up a significant portion of the plane’s nose.
In terms of survivability, the A-10’s airframe is renowned for its ruggedness. The plane can withstand direct hits from armor-piercing and high-explosive projectiles up to 23mm. Its self-sealing fuel cells are protected by internal and external foam. The cockpit and parts of the flight-control system are protected by a ‘bathtub’ of titanium armor, one of the toughest metals, that can also withstand 23mm rounds.

Experts often laud the A-10 for its durability and effectiveness in the CAS role. Lieutenant General David Deptula, a retired officer of the U.S. Air Force, stated, “The A-10’s ability to loiter for extended periods and deliver a wide variety of weapons precisely where needed makes it a key player in the kind of irregular warfare that has characterized recent conflicts” (Source: “Airpower for Irregular Warfare.” Air & Space Power Journal.)
Books such as “Warthog: Flying the A-10 in the Gulf War” by William L. Smallwood, detail the aircraft’s prowess in combat and underline how pilots value its durability and firepower. The claim here is that the A-10 is an exceptional close-air-support platform.
The New York Times, have reported on the U.S. Air Force’s attempts to retire the A-10, citing its age and maintenance costs. The claim often made here is that despite its age, the A-10 remains an essential component of the military’s combat capabilities, as evidenced by its continual reprieve from retirement due to its performance in conflict zones.
While the A-10’s service life has been extended multiple times due to its unique capabilities, the reality is that maintaining and updating these aging aircraft is becoming increasingly challenging and costly. To this end, the U.S. Air Force has launched the OA-X program (light attack experiment) to find a potential replacement for the A-10, focusing on light-attack aircraft that can operate in low-threat environments, which was reported by multiple reputable military news outlets such as Defense News.
When we examine the science behind the A-10’s capabilities, we must address the concepts of aerodynamics, structural design, and propulsion. The aircraft’s straight-wing design provides excellent lift characteristics at slow speeds and low altitudes, perfect for the CAS role. Its twin turbofan engines provide sufficient power for quick maneuvering while also keeping the plane’s infrared signature low. This minimizes the risk of being targeted by heat-seeking missiles, a significant threat in low-altitude combat scenarios.
The A-10 Thunderbolt II or the “Warthog” is a specialized aircraft, built for a specific purpose: close air support. It showcases a number of innovations in aircraft design and weaponry, and its remarkable durability has cemented its legacy as one of the most effective ground-attack aircraft in the world. Despite being in service for over four decades, the A-10 continues to be an invaluable asset in various conflict zones around the world.
