Video: Incredible Video of A-10 Warthogs Fearsome GAU-8 Avenger in Action
The A-10 Thunderbolt is also known as the Warthog, the ‘flying gun’ and the Tankbuster.
The A-10 is a high-survivability and versatile aircraft, popular with pilots for the ‘get home’ effectiveness.
The mission of the aircraft is ground attack against tanks, armoured vehicles and installations, and close air support of ground forces.
The A-10 is suitable for operation from forward air bases, with short take-off and landing capability. The aircraft has a long range (800 miles), high endurance and can loiter in the battle area.
The manoeuvrability at low speed and low altitude (below 1,000ft) allows accurate and effective targeting and weapon delivery over all types of terrain.
The GAU-8/A 30mm Gatlin gun iis installed on the U.S. Air Force’s A-10 Thunderbolt II aircraft and the Navy’s Goalkeeper Close-In Weapon System. The GAU-8/A provides a reliable, high-rate-of-fire, combat-proven weapon for close air support and shipboard defense missions.
Each of the gun’s seven barrels contains its own breech bolt assembly, which fires once per gun revolution. This ensures long barrel life because firing loads are distributed over all seven barrels. Continuous rotary motion reduces impact loads on gun components, leading to long parts life and high reliability.
The A-10 aircraft is specifically designed to provide close air support. The GAU-8/A gun provides rapid response to threats that are in close proximity to friendly ground forces and is well suited for engagements inside missile envelopes.
In the Goalkeeper application, the GAU-8/A fires a lethal, high-kinetic-energy 30mm Missile-Piercing Discarding Sabot round.

Well, This Katana took me too long to make and this was not easy to make it such perfect. Alot of People asked me to make Katana so i tried my best to make a perfect Katana Sword as i can.
All the Processes are below of making this beautiful KATANA:
Forging:
It took me almost three days to hand forge an Iron Chain piece into a long Metal Strip and this was one of my hardest forging ever. I dont have a power hammer so i did all the forging with hands and turned a chain piece into an almost 33 — 34 inches long steel strip.
Grinding:
I started some rough grindings of long strip on my Belt sander and turned the strip into a Katana shaped long steel piece. I also hand sanded the edges with the help of file to remove almost all the roughness of the sword.
o. I made the Blood Groove with the help of rotary grinder.
o. The blade bevel was made by my professional angle grinder.
o. Hand Sanded the blade to remove roughness.
Hardness:
There is a professional way to harden a Katana and that is
Covering the whole sword in a Fire Clay (Insulation) Except the blade bevel.After that we put the sword into the fire and heat it to critical temperature. We use oil to Quench the heated sword in it. Now the Bevel is hard and the remaining sword is annealed. Tempering the blade is the best way to increase the Strength, Hardness and Toughness of the sword.
Hibaki:
This piece is traditionally made by forging some copper or brass but we can also make it by casting these metals. And the purpose of hibaki is to hold the Sheath with the handle.
Handle:
The Handle contains three parts.
o. GUARD: I made the guard by using a thick brass sheet, which is roundly turned into a beautiful metal piece that can show a partition between the handle and the remaining sword.
o. Spacer: This is the little metal piece which fits on tang and controls the fittings of the whole handle so nothing should vibrate in handle.
o. Wood: A nice piece of wood uses as a handle of the sword and that could be Wrapped by some soft (leather) strips.
