Can precision-guided weapons replace massed artillery?

“Replace” is the wrong historical verb; the pattern is “add a new layer, then doctrine adapts.” Massed fire has been the backbone since at least the Napoleonic era, but the modern template really forms in WWI: artillery as the primary killer, used for neutralization, suppression, interdiction, and shaping. WWII deepened it (Soviet “artillery offensives,” U.S. time-on-target), and the Cold War made it institutional (Warsaw Pact fire planning vs NATO counter-battery and air interdiction).

Precision does something mass can’t: reliably hit point targets quickly, often first-round effects—radars, bridges, command posts, key vehicles. But massed artillery does something precision can’t economically sustain: persistent area effects over time—keeping heads down, breaking up attacks, denying ground, and forcing dispersion.

Even in conflicts where precision dominates the public narrative, conventional artillery remains essential because wars are messy: targets are fleeting, coordinates are imperfect, weather and obscurants happen, and you often need effects on a grid square, not a single window. The best historical analogy is not “PGMs replace guns” but “PGMs shift what guns are asked to do.” You end up with a mix: precision for critical nodes, mass for suppression/attrition, and constant adaptation to countermeasures.

If you want a good doctrinal lens, look at U.S. FM 3-09 (Fires) and NATO fires publications: they treat precision as a capability inside a broader fires system, not a substitute for volume.

From an “equipment ecosystem” angle, precision-guided weapons don’t live in a vacuum. To make precision work consistently you need the whole chain: observers, drones/optics, comms, power, secure GPS/INS, targeting software, and the people trained to run it under stress.

Massed artillery is brutally simple by comparison: lots of tubes, lots of ammo, basic fire control, and you can still get useful effects even when everything is degraded. Precision is awesome when your kit is intact; it gets less awesome when batteries die, antennas break, the tablet gets jammed, or you can’t keep a drone in the air.

Also, “cost” isn’t just per round. A guided projectile can save logistics (fewer rounds moved), but it can increase dependency on delicate components and supply chains. If the fight is long and nasty, the side that can keep feeding guns with standard shells often has an ugly advantage.

My take: precision should complement massed fires. If you have to choose one capability to keep working when conditions are awful, I’d bet on simple, robust artillery + good observers. The fancy stuff is the multiplier, not the foundation.

In training and in the real world, the key word is “effects.” Commanders want suppression, obscuration, isolation, and destruction—sometimes all at once. Precision gets you destruction of specific things. Massed artillery gets you suppression and shaping on demand.

When you’re moving or defending, you don’t always have the luxury of perfect target confirmation. You might have “enemy in tree line” or “suspected mortar position,” and you need immediate effects to buy time. A few guided rounds might miss the reality on the ground because the target shifted 50 meters. A lot of conventional HE over that area tends to fix the problem.

Also, sustained fire matters. Counter-battery is real, so you displace, shoot, move—still, volume over time is a form of pressure. Precision is fantastic for high-value targets, but you can’t build your whole plan around munitions you can’t afford to expend at scale.

So no, precision doesn’t replace mass. It makes your fires smarter, and it changes priorities, but you still need the ugly basics.

People keep trying to “tech” their way out of reality: war is mostly about who can generate more combat power for longer. Precision-guided weapons are not magic wands.

Here’s the uncomfortable point: suppression wins fights, and suppression is about volume and persistence. If you think you can replace massed artillery with expensive boutique munitions, you’re basically betting your campaign on flawless ISR, unjammed navigation, perfect comms, and a target set that politely holds still.

Sure, precision kills the special stuff—HQs, air defenses, bridges—great. But when the enemy is dug in, dispersed, and rotating units through cover, you need lots of steel in the air. And if the other side can produce shells and you can’t, your “precision-only” force structure turns into a spreadsheet fantasy.

Precision is a tool. Mass is a strategy. Ignore that and you’ll relearn old lessons the hard way.

Precision-guided weapons are getting closer to replacing some traditional artillery missions, but mostly because the targeting loop has changed. Drones give persistent ISR, quick battle damage assessment, and real-time correction. That makes “one round, one target” more achievable.

But the same drone-centric battlefield also argues for keeping massed artillery: once both sides have ISR, anything emitting gets found, and you need quick, repeated fires to disrupt movement and force concealment. Also, electronic warfare is a precision killer—GPS denial, datalink disruption, spoofing. A dumb shell doesn’t care about GNSS.

Where I see “replacement” happening is in certain niches: loitering munitions and small UCAVs can do counter-battery hunting, trench-line harassment, and point strikes with less risk to crews. They don’t fully replace artillery, but they steal missions from it.

Future mix looks like: drones find, AI helps prioritize, precision strikes key nodes, and conventional artillery provides the continuous pressure. The winners are the ones who integrate all of it under EW stress.

Against armored formations, massed artillery still has a major role even in a precision era. Armor doesn’t die only from direct hits—mobility kills matter. Conventional fires crater routes, cut off resupply, force vehicles into predictable lanes, and strip dismounted infantry of confidence.

Precision is great for killing specific high-value vehicles (air defense, command variants, recovery vehicles, bridging assets). But in mechanized warfare, the critical problem is often tempo: stop the advance, break cohesion, and create windows for AT systems and air to work.

Also, modern armor often survives near-misses better than people assume, especially if it’s buttoned up and using terrain. That pushes you toward repeated effects over an area—DPICM used to be the classic answer; now you see alternative submunitions/area effects and lots of conventional HE to suppress and canalize.

Bottom line: PGMs help you surgically remove key enablers, but massed artillery is still the “friction generator” that makes mechanized forces slow, predictable, and vulnerable.

From a maritime perspective, the question maps to “precision strike vs volume fires” too. Navies love precision because sea control often hinges on a few high-value assets (ships, radars, airbases). But even at sea, volume matters: saturation attacks overwhelm defenses; sustained fires create area denial.

If you look at littoral operations and amphibious support, naval gunfire is the classic “massed artillery” analog—less common now, but still valued because it can deliver repeated effects without burning expensive missiles. Missiles are for high-value targets and time-sensitive strikes.

Translate that back to land: precision can cripple key nodes, but it’s hard to use precision economically to provide hours of suppressive fire on multiple objectives. Also, when guidance is contested (EW), dumb fire retains value.

So, no full replacement—more like a division of labor between precision strike and sustained fires, with logistics and countermeasures deciding the mix.

Airpower went through the same argument: “smart bombs make mass bombing obsolete.” What happened is that precision increased effectiveness, but it didn’t eliminate the need for lots of sorties and lots of weapons in contested environments.

Precision-guided weapons depend on access: you need air superiority or at least enough suppression of enemy air defenses to get sensors and shooters in range. When airspace is contested, artillery becomes even more important because it can deliver fires without exposing aircraft the same way.

Also, weather, smoke, and EW can degrade targeting for air and ground precision. When that happens, being able to put a lot of rounds into an area—fast—still matters to support troops in contact.

The cleanest answer: precision-guided weapons can replace some missions traditionally done by massed artillery (especially point targets), but they can’t replace the artillery role of continuous support and suppression across a wide front.

If you’re asking this as someone considering a military path: modern fires careers are becoming more “systems” oriented, not less. Precision munitions add jobs around sensors, targeting, networking, and EW awareness, but conventional artillery skills still matter.

In most militaries you’ll see overlap: forward observers/JTAC-type roles, fire direction, radar/counter-battery, and UAV integration. The trend is multi-domain coordination rather than one weapon replacing another.

If you want to learn more, look up basic artillery concepts like call-for-fire, target acquisition, and fire support planning. Then add modern topics: GPS-denied operations, drone spotting, and deconfliction.

And if you’re joining, ask a recruiter about roles that sit at the intersection (fires + UAVs + targeting), because that’s where precision vs mass becomes a day-to-day planning problem.

Special operations is where precision looks like it “wins,” because SOF missions often prioritize limited collateral damage, fast in-and-out raids, and hitting specific nodes. In that context, a single guided munition or a loitering munition can be more useful than a battalion-level fire plan.

But SOF doesn’t fight the whole war. Big conventional formations still need suppression to maneuver. Even SOF teams frequently want conventional fires available as a safety net—especially for breaking contact or shaping an objective area.

Also, precision doesn’t remove the need for isolation: you still may want artillery to block roads, deny reinforcement routes, and create uncertainty. That’s not always a one-shot job.

So precision can replace mass for certain discrete tasks, but not for the broader requirement of controlling space and tempo across a front.

At the ground level, massed artillery and precision-guided weapons create different “survival problems.” Precision is scary because if you’re detected and fixed, you can be hit very accurately. Mass is scary because it punishes patterns and forces you to live under constant disruption.

In practice, armies still rely on massed fires to force people to dig, disperse, camouflage, and move less. That affects endurance: sleep, hydration, repairs, resupply. Precision doesn’t necessarily keep you pinned for hours; volume fires can.

From a fieldcraft perspective, the more precision exists, the more important concealment and emission discipline become (lights, comms, vehicle heat signatures). But no matter how precise weapons get, area fires will still be used to deny terrain and make movement costly.

So I doubt precision fully replaces mass—because mass is as much about controlling behavior as it is about destruction.

Replacement arguments usually collapse when you look at industrial capacity and politics. Precision-guided munitions require specialized components, tighter quality control, and often international supply chains. In prolonged wars, procurement bottlenecks and export controls become operational factors.

Massed artillery relies on simpler manufacturing and stockpiles. If a state anticipates a long conflict, it tends to hedge with large conventional inventories because they’re easier to scale.

There’s also signaling and alliance dynamics: partners may share precision weapons selectively, but conventional ammunition production can be ramped domestically or through multiple suppliers. And adversaries invest heavily in EW specifically to reduce the advantage of precision.

So, could precision replace mass in a short, high-intensity campaign with air dominance and stable supply? Maybe partly. In a long grinding conflict with contested EW and attrition, massed artillery remains hard to substitute.

Logistics is the spoiler for “precision replaces mass.” Precision can reduce the number of rounds needed for a given destruction task, which is great. But massed artillery’s advantage is throughput and resilience: you can keep firing even when the network is degraded.

Engineering considerations matter too. If the goal is to deny mobility—turn roads into craters, collapse trench systems, cut approach routes—you often need repeated effects over time, not a single accurate hit. Repairs happen. The enemy routes around damage. So the requirement becomes persistent fires.

Counter-battery and survivability push both sides toward shoot-and-scoot, decoys, hardened positions, and dispersed ammo points. Precision munitions help by letting you fire fewer rounds from fewer positions, but they also depend on precise targeting data and reliable navigation.

In planning terms: precision is efficiency; mass is capacity. You want both, and you design the sustainment plan accordingly.

I’m still learning this stuff, but I’m confused about one part: if drones can spot targets so well now, why wouldn’t you just use guided rounds for everything and stop wasting ammo?

Is it mainly cost, or is it that jamming makes guided shells unreliable? Also, when people say “suppression,” does that literally mean you’re firing even if you’re not sure you’ll hit anything, just to keep the enemy down?

If anyone has a simple example (like defending a trench line vs attacking across open ground), that would help me understand why massed artillery is still a thing.

In most force-structure models, you don’t optimize for average conditions; you optimize for worst-case and for adaptability. Precision-guided weapons push you toward a “networked” kill chain: sensors, comms, data fusion, then shooters. That’s powerful but brittle if the network is contested.

Massed artillery is a parallel system that still functions with degraded inputs. In a sim, when you introduce fog of war, decoys, EW, and attrition of sensors, the marginal value of cheap rounds rises because you can still generate effects without perfect information.

The likely future is portfolio fires: a baseline of conventional tubes/ammo to guarantee sustained outputs, plus a smaller percentage of precision to maximize effectiveness against high-value nodes. The exact ratio depends on budget, industrial base, and expected EW intensity.

So replacement is unlikely. The strategic question becomes: how much precision can you afford, and how much mass do you need to remain operational when the “smart” part gets disrupted?

If anything “replaces” massed artillery, it’s not one precision weapon—it’s a robotics-enabled swarm plus automated targeting that can generate continuous pressure without the same ammo logistics. Think large numbers of cheap loitering munitions, autonomous ground launchers, and distributed sensors.

But we’re not at a point where autonomy erases the need for volume. It just changes the form of volume: instead of thousands of shells, it might be thousands of small autonomous effects. And that future still faces the same constraints: EW, contested spectrum, spoofing, and production scale.

Also, ethics and policy will shape how much autonomy is allowed in targeting, which affects how “automatic” precision can really be.

Near term: precision-guided weapons reduce how much artillery you need for certain target sets, but massed fires remain the dependable backstop when the battlefield gets chaotic and the network gets ugly.
