00:00To destroy heavy defenses before ground troops ever arrive, militaries rely on artillery.
00:07These long-range strike weapons hit targets miles over the horizon.
00:12During the Second World War and through Vietnam, the American military leaned on heavy steel
00:18cannons like the M114 howitzer to deliver that explosive force.
00:23But aiming these guns required crews to perform manual calculations on the fly.
00:30They had to factor in wind, weather, and elevation using slide rules and paper charts.
00:36That heavy steel provided immense brute force, but how effectively a crew could use it was
00:42completely capped by the speed and limits of human math.
00:46As enemy weapons evolved, keeping artillery crews alive meant moving them further and
00:52further back from the front lines.
00:54But shooting further creates a geometry problem.
00:58A tiny miscalculation at the firing point widens over distance, causing a complete mess.
01:04Add complex crosswinds and changing air density, and the overlapping data points quickly overwhelm
01:12manual calculation.
01:14How can a crew reliably hit a distant bunker when the required math is no longer fast or
01:20accurate enough to calculate by hand?
01:23Increasing range while protecting crews required a system capable of processing atmospheric variables
01:30faster than any human operator.
01:33By the late 1970s, the military tried to brute force a solution with the M198 howitzer, using
01:40a longer barrel and lighter materials to push shells further.
01:44A similar hardware focus created the low-weight M119, built specifically so helicopters could
01:52rapidly drop guns into isolated terrain.
01:55Despite these hardware upgrades, the targeting systems remain tied to the same manual plotting
02:01methods used decades earlier.
02:03At extended ranges, crews took precious minutes to calculate their shots.
02:08That delay left them exposed as sitting targets for enemy counter-attacks while they finished
02:13the math.
02:15Physical engineering had reached its limit.
02:17Building a more capable gun was useless without building a faster brain to aim it.
02:23The M777 solved this math problem by combining ultralight titanium hardware with the military's
02:31first fully digital fire control system.
02:34Instead of paper charts, onboard computers and GPS-guided Excalibur rounds instantly execute
02:42the complex atmospheric math that used to cost human crews crucial minutes.
02:47When you put that digital brain onto a tracked, armored chassis, you get the M109 Paladin, built
02:54specifically for fast-paced, mechanized warfare.
02:57The modern threat these crews face is counter-bottery radar.
03:01As you can see in this animation, an automated radar wave intersects an incoming projectile and
03:08instantly traces a line back to pinpoint the exact firing location.
03:12To evade that tracking radar, the Paladin uses digital navigation for a shoot-and-scoop
03:18maneuver, stopping, firing, and moving again in a matter of seconds.
03:22Digital fire control maximized precision, but more importantly, it gave artillery crews the
03:29mathematical speed necessary to survive returning fire.
03:34The extreme future state of this digital foundation is the XM1299 Extended Range Cannon Artillery.
03:43Built on the Paladin chassis, it features a massively extended barrel to transfer the maximum amount of
03:49physical energy directly to the projectile.
03:52By pairing that immense physical energy with advanced algorithmic targeting, the system is
03:58designed to accurately strike targets for more than 40 miles away.
04:03This map illustrates the advantage.
04:05A massive 40-mile radius allows commanders to safely eliminate enemy air defenses and command
04:12posts from well over the horizon, completely outside the enemy's defensive range.
04:1780 years ago, crews were manually guessing wind vectors to fire blind over the next hill.
04:24Today, they execute surgical, algorithm-driven strikes across entire counties.
04:30The transition from manual estimation to digital precision allows modern forces to control the
04:38battlefield from distances once considered unreachable.
