Future Firearms for Writers

Metal Storm AICW - Internal View

Firearms development is a funny thing; for centuries it crept along. A 16th Century musketeer would have had little difficulty understanding and mastering an early 19th Century firearm. Then, in the second half of that century there was an explosion of development. Metallic cartridges, repeating weapons, machine-guns and semi-automatic rifles and handguns. Then things slowed down again. A soldier from World War One would have no trouble figuring out and using modern firearms. The 20th Century was more a time of refinement than of revolution. Designs were optimized and materials science improved, but the basics remained the same.

This trend has continued into the 21st Century. manufacturing methods and materials have improved, but only relatively insignificant refinements to the weapons themselves. Projectile designs have also been refined for greater reliability, but as yet no revolutionary technology has come along.

The US Army adopted the M16 Rifle about fifty years ago, and they have several times made extensive studies of potential replacements. None of those studies succeeded in coming up with anything enough better to bother. The design has been refined and modified into other configurations (like the M4) but the basics are the same.

Firearms are an apex technology; they have reached levels of efficiency and effectiveness that make it very difficult to make significant advances. In the near future all we’re likely to see change are the ‘fiddly bits;’ how the components are arranged and what they are made of. I suppose that is good news for science-fiction writers; we don’t need to worry about the basics. In twenty, forty or fifty years our heroes will most likely rely on guns that use metallic cartridges filled with propellant and a projectile that works pretty much the way these things work now. One less thing to worry about, right?

Well, yes and no.  While the weapons haven’t changed much in recent decades and probably won’t change much for the next few decades something is going to change- the information technology revolution has come to firearms, and this will effect the way that we use them. Information systems, graphics systems, AI and combined arms are all coming together to shape the future battlescape. Here’s an example:

An infantry squad is pinned down by a heavy machine-gun in a bunker 800 meters in front of them. It is beyond the effective reach of either their individual weapons or grenade launchers. They need help.

One soldier flips a monocle attached to his helmet over his eye and extends his weapon. A camera on his weapon transmits the image of where the weapon is pointed to the monocle. He centers the cursor over the bunker and presses a button. Now a lot of things happen very quickly.

A black-box on the gun locates the weapon to within a half-inch using GPS. A laser range-finder ranges the bunker. Another system notes the weapons exact bearing and elevation and uses this information combined with the range to generate an exact GPS coordinate for the bunker, then alerts the soldier. He presses another button and a ‘call for fire’ goes out over the combat intranet.  A computer far behind the lines notes the call and consults an inventory of assets in position to respond. It makes it’s choice and sends an order.

Twelve miles from the bunker a self-propelled howitzer gets the call for fire and stops. An on-board computer consults meteorological data generated by satellites, sensors deployed by artillery or individual soldiers and drones flying between the gun and the target. It takes this data, the gun’s GPS location and consults a database about ballistics and propellant performance. By the time the vehicle has stopped, deployed it’s recoil spades and the crew has loaded the weapon the computer has a firing solution and has aimed the gun.

The gun fires a dumb, un-guided high-explosive shell with an accuracy of plus-or-minus two meters at 13 miles… thirty seconds later the bunker is vaporized and the squad can continue towards their objective. Elapsed time approximately 3 minutes.

Sounds like science-fiction, right? It isn’t; this scenario isn’t even state of the art. It actually happened in 2003 in Iraq.

The gun may stay the same, but the interface between soldier and gun- and other systems in support- will continue to improve and become easier, more intuitive, to use. We’ve seen a lot of innovation in this are already; ‘Smart-Gun’ links that allow more rapid, more precise aim under a variety of conditions by projecting a point-of impact on the soldiers optics. A sight system that does all of the calculations for the sniper and automatically adjusts the point of aim so that even a novice has a good chance of hitting a target at 1000 meters— with their first shot. Compact holographic sights- small enough to mount on a handgun- are available and becoming more affordable, reliable and robust all of the time.

Don’t get me wrong; while many of these systems will allow a novice to use a weapon more effectively skill and experience will still be needed to wring the most out of these systems. We’re a long way from the ‘Monkey pushes a button’ stage.

My advice to writers about near future weapons is this- don’t focus on the weapons themselves; focus on the interface between the gun and it’s user, and the off-board systems that will exist to support them. That s where we will see the most innovation in the near-future.

Don’t even get me started on battlefield robots…

      Guided projectiles will be a thing, though probably not for general use. Currently such projectiles are rather large (.50 caliber,) very expensive and guidance is somewhat limited; the velocity of the round means you won’t be shooting around corners or anything like that. The utility for these is mainly for snipers firing at extreme ranges where the target will have several seconds to move after the round is fired. As for explosive projectiles these also have limited utility. First the amount of explosive that a small-arms projectile can contain is very limited; in practice the best of these have typically had no greater effect than hollow-point ammunition of the same caliber. Another problem is that a bullet that explodes on impact might not penetrate deeply enough to insure incapacitating the target. I am sure at some point a ‘smart’ explosive bullet can be designed; one that will penetrate an appropriate depth before exploding so that is is in the midst of vital structures (majory arteries, vital organs etc.) where it can do the most damage. There is a balancing act to be done, and kinetic energy is a bitch; adding chemical energy (explosives) to that against human targets is sort of unnecessary.
