SunnyD has a point. If that shit could be hacked, and, honestly, what can't, the enemy could set the round to go off as soon as it exited the barrel.

Not really. Look at 40mm launchers. The grenade has to spin so many times before it arms. These work the same way. Point it straight at the ground and physical safeties prevent it from detonating at your feet.

I think the wireless part is not much of a concern, most likely the radio range is small, like within the gun. Basically you are setting the prime within the chamber.

Well, given the ammo has the receiver in it, a sufficiently powerful transmitter would easily override the one in the gun itself. Personally, the idea of "smart ammo" seems rather counterproductive, given that "smart" anything is bound to be hacked in a matter of time. Anything that communicates via radio frequencies are simply that much more prone to be exploited.

I would imagine they would countersign the gun and ammo similar to glucometers and fresh pack of test strips.

You slide the mag into the gun, the bullets talk with the gun, locking them to the gun and will only accept command from that gun.

Well good thing it's not set through radio then. According to some interent research, it seems to be inductively set. This seems to be the Army's preferred method for GPS fuzes, not that this one is GPS.

I'm pretty sure the germans are gonna stick a microchip or two that will make the guns explode just in case...

Hope it's EMP hardened.

Seems overly complicated. I hope it doesn't fail on the fly in the real world of combat.

I thought the number one threat was from terrorists?
Will it stop a shoe bomber from bringing down a plane?

No but when we chase down the people who trained\mentored the bomber... less collateral damage.

The idea that this could be hacked is overstated. It isn't hard to shield the gun from allowing transmissions into the weapon and the rounds themselves wouldn't have anything to "hack" once fired. The fuse would be set by the casing itself and once fired the round would detonate based on the set rotations and there's nothing left to "hack."

This doesn't even get into very basic encryption methods between the gun and the ammo itself that would prevent unauthorized access to the fuse if shielding wasn't absolute.

As much as the UAV feed problem is mentioned, successful and impenetrable operational encryption by the US Military and its extent far outweighs that incident.

2 years old, at least. i'll bet this thing disappears into obscurity like 99% of all weapons developed in the past 10 years.

We're fighting people who take $5 worth of shit from radio shack, attach it to old Soviet warheads and take out millions of dollars worth of manpower, training and equipment. Somehow, I doubt that a gun which shoots $25 bullets is going to fix that.

This thing and its ammo would never be practical to produce in the quantities needed.

WTF? The military is paying $30k for their M4s? How does that add up? Good holographic sites are only a few hundred bucks.

holo sites START at a few hundred......and end in the thousands. until you go NV and thermal ETC of course, then its easily 5 figures I would guess

Why not? The gun costs $30k and the bullets cost $25. It costs a hell of a lot more than that to send one soldier into battle, so adding one of these to say, 1 out of every 3 soldiers is a drop in the bucket.

Not necessarily just cost, but capacity. ATK has been maxed out for the better part of a decade now. Can't keep up with the orders they have, much less starting an entire new production line.

Probably because they cost too much and don't work as advertised, especially in the heat of battle. All you ever need is a rifle that spits bullets every time you pull the trigger, like an AK-47.

Rifles and grenade launchers are too entirely different beasts.

FWIW, even the Soviets abandoned the AKM (AK-47) in favor of a rifle that was (more) accurate that fired a more effective (and expensive) bullet, the AK-74 / 5.45mm.
