Unmanned and computer-controlled drones, with no ‘man in the loop’?

The X-47B is an experimental jet — that’s what the X stands for — and is designed to demonstrate new technology, such as automated takeoffs, landings and refueling. The drone also has a fully capable weapons bay with a payload capacity of 4,500 pounds, but the Navy said it has no plans to arm it.
The Navy is now testing two of the aircraft, which were built behind razor-wire fences at Northrop Grumman Corp.’s expansive complex in Palmdale, where the company manufactured the B-2 stealth bomber.
Funded under a $635.8-million contract awarded by the Navy in 2007, the X-47B Unmanned Combat Air System Carrier Demonstration program has grown in cost to an estimated $813 million.
Last February, the first X-47B had its maiden flight from Edwards Air Force Base, where it continued testing until last month when it was carried from the Mojave Desert to Naval Air Station Patuxent River in southern Maryland. It is there that the next stage of the demonstration program begins.
The drone is slated to first land on a carrier by 2013, relying on pinpoint GPS coordinates and advanced avionics. The carrier’s computers digitally transmit the carrier’s speed, cross-winds and other data to the drone as it approaches from miles away.
The X-47B will not only land itself, but will also know what kind of weapons it is carrying, when and where it needs to refuel with an aerial tanker, and whether there’s a nearby threat, said Carl Johnson, Northrop’s X-47B program manager. “It will do its own math and decide what it should do next.”
As Dashiell Bennett observes, doing its ‘own math’ raises many questions:
It [X-47B] could also revolutionize military and international law, as leaders must decide if they can authorize machines to make “lethal combat decisions” — and if anyone back home can be held be responsible when they do. We all saw the Terminator movies, so we know that usually turns out.
Military technology: Magic bullets | The Economist
The US military is now using a rifle that reads like a science fiction novel: each bullet has a computer chip that calculates trajectory and then blows up when it is near its target, killing the enemy with shrapnel:

The XM25, as the new gun is known, weighs about 6kg (13lb) and fires a 25mm round. The trick is that instead of having to be aimed directly at the target, this round need only be aimed at a place in proximity to it. Once there, it explodes—just like Shrapnel’s original artillery shells—and the fragments kill the enemy. It knows when to explode because of a timed fuse. In Shrapnel’s shells this fuse was made of gunpowder. In the XM25 it is a small computer inside the bullet that monitors details of the projectile’s flight.
A handful of XM25s are now being tested in Afghanistan by the Americans. So far, they have been used on more than 200 occasions. Most of these fights ended quickly, and in America’s favour, according to Lieutenant-Colonel Shawn Lucas, who is in charge of the weapon’s field-testing programme. Indeed, the programme has been so successful that the army has ordered 36 more of the new rifles.
A new equaliser
Each rifle bullet is programmed, before it is fired, by a second computer in the rifle itself. To determine the distance to the target, the gunman shines a laser rangefinder attached to the rifle at whatever is shielding the enemy. If that enemy is in a ditch, a nearby object—a tree trunk behind or to the side of the ditch, perhaps—will do. Looking through the rifle’s telescopic sight, the gunman then estimates the distance from this object to the target. He presses a button near the trigger to add that value to (or subtract it from) the distance determined by the rangefinder.
When the round is fired, the internal computer counts the number of rotations it makes, to calculate the distance flown. The rifle’s muzzle velocity is 210 metres a second, which is the starting point for the calculation. When the computer calculates that the round has flown the requisite distance, it issues the instruction to detonate. The explosion creates a burst of shrapnel that is lethal within a radius of several metres (exact details are classified). And the whole process takes less than five seconds.
Just how the turn-counting fuse works is an even more closely guarded secret than the lethal radius—though judging by the number of failed attempts to hack into computers that might be expected to hold information about it, many people would dearly like to know. Certainly, the trick is not easy. An alternative design developed in South Korea, which clocks flight time rather than number of rotations, seems plagued by problems. Last year South Korea’s Agency of Defence Development halted production of trial versions of the K-11, as this rifle is called, and announced a redesign, following serious malfunctions.
The XM25, in contrast, appears to work well. It is accurate at ranges of up to 500 metres. That is almost as far as America’s main assault rifle, the M-16, can shoot conventional bullets with accuracy. More pertinently, it is nearly double the range of the AK-47, a rifle of Soviet design that is used by many insurgent groups. And according to Sergeant-Major Bernard McPherson, part of the XM25’s development programme in Virginia, it is receiving rave reviews from soldiers in the field.
We are moving into a world where all designed objects will be connected, and calculating: everything is potentially smart, not just our phones.
Smart coffee mugs, smart toilets, smart money, smart business cards, smart doorknobs.
