Kartveli's A-10 Design Remains Vital As The U.S. Air Force Turns 70

Today, the U.S Air Force turns 70 years old.

Since the U.S. military's first aircraft purchase from the Wright brothers in 1909, the A-10 Thunderbolt II, nicknamed the "Warthog", is perhaps the most effective aircraft design in history. The A-10 has played a vital role in every theatre of war since the 1970's and is feared by every enemy who has encountered the nose-mounted 30mm Gatling gun and the plane's legendary durability.

The U.S. has put off the retirement of a 1970s era fighter plane, citing its effectiveness in the fight against the Islamic State military group among the reasons for keeping the jets flying.

The A-10 is a close-support aircraft designed by Alexander Kartveli in the early 1970s to counter Soviet armored forces. The twin-engine jet is not fast but is able to engage a wide variety of ground targets with its main gun, a 30mm cannon, as well as missiles, rockets and other munitions launched or dropped from wing pylons. Like many of Kartveli's airplane designs, the plane is also extremely durable and can withstand considerable damage from ground fire and keep flying.

Major role in Iraq War, Afghanistan

The A-10 was first used in combat during the 1991 Gulf War, destroying thousands of Iraqi tanks, armored vehicles and artillery pieces. It has played a role in most major U.S. military action since then, including the Balkans conflict in the late 1990s, the Iraq War and Afghanistan.

The U.S. Air Force has called for retiring the A-10, citing budget savings and saying the aircraft's role can be filled by newer, more versatile planes. But the 2017 Defense Department budget says the Warthog will keep flying at least through 2022.

Efficient in combating IS

Last year, former U.S. Defense Secretary Ashton Carter told Congress the A-10's usefulness combating IS in Iraq and Syria is one reason the Pentagon wants to keep the plane.

"I saw some of the A-10s that are flying bombing missions against ISIL when I was at Incirlik Air Base in Turkey last December, and we need the additional payload capacity they can bring to the fight," Carter told a House Appropriations subcommittee. "We're pushing off the A-10's final retirement until 2022 so we can keep more aircraft that can drop smart bombs on ISIL."

ISIL is another acronym for Islamic State.

Sen. John McCain, a long-time supporter of the A-10, said last year he was pleased the Warthog would remain in the U.S. arsenal.

“I look forward to seeing our A-10 pilots continue to make important advances in the fight against ISIL in the Middle East, boosting NATO’s efforts to deter Russian aggression in Eastern Europe, and supporting vital missions for U.S. national security wherever they are needed,” McCain said in a statement.

How A Georgian Folk Song Travelled To Deep Space On Nasa Voyager Missions

Pioneers 10 and 11, which preceded Voyager, both carried small metal plaques identifying their time and place of origin for the benefit of any other spacefarers that might find them in the distant future. With this example before them, NASA placed a more ambitious message aboard Voyager 1 and 2, a kind of time capsule, intended to communicate a story of our world to extraterrestrials. The Voyager message is carried by a phonograph record, a 12-inch gold-plated copper disk containing sounds and images selected to portray the diversity of life and culture on Earth.

The Alexander Kartveli Association (a Georgian non-profit) is a sponsor of the film, The Song.

The contents of the record were selected for NASA by a committee chaired by Carl Sagan of Cornell University, et. al. Dr. Sagan and his associates assembled 115 images and a variety of natural sounds, such as those made by surf, wind and thunder, birds, whales, and other animals. To this they added musical selections from different cultures and eras, and spoken greetings from Earth-people in fifty-five languages, and printed messages from President Carter and U.N. Secretary General Waldheim.

“The spacecraft will be encountered and the record played only if there are advanced spacefaring civilizations in interstellar space. - Carl Sagan”

Each record is encased in a protective aluminum jacket, together with a cartridge and a needle. Instructions, in symbolic language, explain the origin of the spacecraft and indicate how the record is to be played. The 115 images are encoded in analog form.

The remainder of the record is in audio, designed to be played at 16-2/3 revolutions per minute. It contains the spoken greetings, beginning with Akkadian, which was spoken in Sumer about six thousand years ago, and ending with Wu, a modern Chinese dialect. Following the section on the sounds of Earth, there is an eclectic 90-minute selection of music, including both Eastern and Western classics and a variety of ethnic music. Once the Voyager spacecraft leave the solar system (by 1990, both will be beyond the orbit of Pluto), they will find themselves in empty space. It will be forty thousand years before they make a close approach to any other planetary system. As Carl Sagan has noted, "The spacecraft will be encountered and the record played only if there are advanced spacefaring civilizations in interstellar space. But the launching of this bottle into the cosmic ocean says something very hopeful about life on this planet."
