OFB produce HEAT rounds but not tandem, These are tandem HEAT rounds are imported in some unknown quantity..Kuanl,
Not so far in production in India or is it??
The U.S. military has been after self-guided bullets for years. Now, government researchers have finally made it happen: A bullet that can navigate itself a full mile before successfully nailing its target.The breakthrough comes courtesy of engineers at Sandia National Laboratory, who've successfully tested a prototype of the bullet at distances up to 2,000 meters — more than a mile. The photo above is an actual image taken during one of those tests. A light-emitting diode was attached to the bullet, showing the amazing pathway that the munition made through the night sky.Each self-guided bullet is around four inches in length. At the tip is an optical sensor, that can detect a laser beam being shone on a far-off target. Actuators inside the bullet get intel from the bullet's sensor, and then "steer tiny fins that guide the bullet to the target." The bullet can self-correct its navigational path 30 times a second, all while flying more than twice the speed of sound.
The bullet contains an optical sensor, CPU, battery and electromagnetic actuated fins. It is able to track laser designated targets out to 2,000 meters.:shocked:The CPU tracks laser designed targets using the optical sensor in the nose and can make changes to its flight as often as 30 times per second....Computer simulations indicate that the bullet could theoretically get within 8" of a target at 2,000 meters.
:shocked:Exacto' for ' Extreme Accuracy Tactical Ordnance ' is a guided 12.7mm (0.5"³) projectile under development by DARPA. The program objective is to demonstrate how rifle accuracy and range can be extended by using guided small caliber projectiles. The program focuses on the .50 caliber round, fired by current 'anti material' rifles (like the Barret), equipped with an optical sight and control systems that will more than double the range over current sniper systems, while allowing the sniper to prosecute moving targets even in high wind conditions – a capability unavailable with today's weapons.The system will be able to guide a maneuverable projectile through its flight, as the shooter continues to track the target, delivering guidance corrections to the projectile. Once such capability is matured, Exacto will not be limited to sniper rifles, but could also be employed with vehicle or ship mounted weapon stations, as well as airborne automatic cannons, including 0.5 machine guns or 20mm cannons, that, for the first time, could yield extremely accurate fire from long distance.
The program recently completed its first phase by achieving a successful proof of concept with a high fidelity hardware-in-the-loop (HITL) simulation. Currently at Phase II, under a $25 million contract, Teledyne Scientific & Imaging will build and test a complete system, including the optical sight, guidance system and guided .50 caliber projectiles, to be tested in actual firing by 2012.
And this is Arapaima...Piranha have a well-earned reputation for being able and willing to eat just about anything in their path. One of the few exceptions is the Arapaima, a six-foot long, 300-pound Amazonian predator with bony scales capable of withstanding the toothy onslaught. Researchers are now working to adapt the Arapaima's defenses to protect our own squishy bits.
You'd think a fish the size of an offensive lineman would be able to get by on bulk alone. But, during the dry season, Arapaima are forced to share dwindling pools with the voracious piranha. Its durable scales are what keep the Arapaima intact until the waters rise again.
Its scales are composed of a hard, corrugated outer layer over a pliable layer of collagen. What's more, the fibers that make up the outer layer are arranged in alternating directions—like a parquet floor. This allows the scales to flex as the fish swims and spreads a piranha's bite force out over a larger area, preventing the piranha's teeth from penetrating.
Researchers from UC San Diego, lead by mechanical and aerospace engineering professor Marc Meyers, hope to replicate this "hard on the outside, soft on the inside" system to create bendable ceramics. Conventional ceramics are very hard and quite durable but lose that strength when forced to curve around an object. Corrugation allows the plate to bend without cracking.
"The materials that nature has at its disposal are not very strong," said Meyers, "but nature combines them in a very ingenious way to produce strong components and strong designs." The research team hopes to develop these durable-yet-flexible plates to one day replace the conventional flat plating in soldiers' body armor. [UC San Diego via Gizmag]

Bulletproof vests have to spread the blunt trauma out over the whole vest so that the force isn't felt too intensely in any one spot. To do this, the bulletproof material must have a very tight weave. Typically, the individual fibers are twisted, increasing their density and their thickness at each point. To make it even more rigid, the material is coated with a resin substance and sandwiched between two layers of plastic film.Its scales are composed of a hard, corrugated outer layer over a pliable layer of collagen.

this >>>>>What happened to dragon skin armour ?
What will be the launch platform for these new bullets in that first case? Which one was during that test?
Simple 50cal Sniper Rifle is the platform, It balanced my moving fins indeed, Its a miniaturization of a bigger Guided arty shell...What will be the launch platform for these new bullets in that first case? Which one was during that test?
And you said its balanced in air by the ancient and most basic fins. Fins enhance the penetration power of any ranged ammo. May it be arrows, ATGM, missiles an now these. Are you kidding? Because if not then it will be one the most deadliest technology in the future.
It was just a dream I use to see. And think what could happen if each and every bullet of a 30 round magazine is guided and hits the target accurately. One shot one hit(wont call it a kill).
