This is not your typical military battle. No weapons will be fired, and no troops deployed. This is a budget battle.

In an effort to trim spending, the Air Force is planning to retire hundreds of Fairchild Republic A-10 Thunderbolt IIs, better known as the "Warthog," a move that will save the Air Force more than $3.7 billion by 2020. It is all part of a congressional mandate which aims to cut $50 billion from the Air Force budget over the next five years, just a small part of the more than $500 billion in planned cuts to the Pentagon budget over the next 10 years.

Designed solely for close-air support of ground forces, the A-10 was built to attack tanks, armored vehicles, and other ground targets with limited air defenses. Critics of the Warthog cancellation say it is a militarily misguided plan, one which ditches an effective, combat-proven plane just to save money for the far more expensive and unproven F-35 Lightning II joint strike fighter.

The A-10 Thunderbolt II is the first Air Force aircraft specially designed for close-air support of ground forces. And perhaps a shift from the A-10 may signal an increasing reluctance for ground operations and toward rapid-response strategic strikes.

Take a look at the A-10 Thunderbolt II Warthog through the years.

Here we see an A-10 Thunderbolt in flight in the 1970s. The Warthog's first flight was on May 10, 1972, and it was officially introduced in March 1977. Though slow, the A-10 became known as a highly maneuverable, accurate weapons platform that is the bane of enemy ground forces.

Here, an A-10 Thunderbolt II takes off on a mission against targets in Yugoslavia during the NATO bombing against the Federal Republic of Yugoslavia during the Kosovo War in late 1999.

The A-10 and OA-10 Thunderbolt IIs were the first Air Force aircraft specially designed for close-air support of ground forces, with a unique tank-stopping nose cannon which fires nearly 4,000 rounds a minute.

The Warthog is simple and effective at its close-air support duties, able to be used against virtually any target on the ground, including tanks and other armored vehicles. General Mark A. Welsh III, Air Force chief of staff, said other aircraft -- F-16s, B-1s, and B-52s -- provide roughly 75 percent of the close-air support in Afghanistan today. “We have a lot of airplanes that can perform that mission and perform it well,” he said.

Here, a row of A-10 Thunderbolt IIs wait at the Tallil Air Base in southern Iraq for their missions. These aircraft are part of the 442nd Fighter Wing from Whiteman Air Force Base in Missouri, which was deployed to Talli and Kirkuk Air Bases in 2003.

The Warthog is know throughout the Air Force as one of the most effective close-air support tools available. Here, an A-10C Thunderbolt II with the 188th Fighter Wing, Arkansas Air National Guard conducts close-air support training November 21, 2013, near Davis-Monthan Air Force Base in Arizona.
