How Poland is building the biggest army in its history

In a world where defense budgets are often political footballs, this piece makes a startling claim: Poland is quietly engineering the largest land army in the European Union, with a price tag that defies conventional economics. Good Times Bad Times doesn't just list equipment; they argue that Warsaw is fundamentally rewriting the rules of deterrence, shifting from a strategy of simply holding the line to one capable of striking deep inside enemy territory. For the busy observer, this is not just about tanks; it is a case study in how a medium-sized nation is leveraging crisis to build a military industrial complex that could reshape the continent's security architecture.

The Scale of Ambition

The author anchors the narrative in a staggering financial commitment, noting that "Poland plans to spend on defense... roughly half of its current annual GDP" by 2035. This is not hyperbole; it is a deliberate recalibration of national priorities. Good Times Bad Times writes, "Poland is increasing its defense spending to 5% of GDP. It's modernizing its fleet, purchasing new military equipment, and expanding its domestic defense industry." This framing is effective because it moves the conversation away from abstract geopolitical threats to concrete fiscal reality. The argument holds up under scrutiny: the sheer volume of capital flowing into the sector suggests a long-term commitment that transcends typical election cycles.

However, the author wisely notes that this effort "remains largely outside day-to-day political disputes," a crucial detail that lends credibility to the long-term planning. By 2035, the goal is to operate across all domains, including a "special-purpose division built around elite airborne and air mobility units" designed for deep strikes. This reflects a doctrinal shift that the author describes as moving from "deterrence by denial" to "deterrence by punishment." The distinction is vital; it suggests Poland is no longer content to merely survive an invasion but intends to impose catastrophic costs on an aggressor before they can even cross the border.

"Traditionally, Poland relied on deterrence by denial... The new goal moves a step further. Deterrence by punishment, the capability to impose significant cost deep inside an adversaries territory."

Critics might argue that such an aggressive posture could escalate tensions rather than prevent them, but the author counters this by highlighting the sheer defensive necessity born of the war in Ukraine. The text notes that the expansion includes growing the force from "about 100,000 active personnel a few years ago... to as many as 500,000," creating a massive reserve force. This scale is unprecedented for a nation of Poland's size, echoing the historical mobilization efforts seen during the formation of the 11th Armoured Cavalry Division, which has long served as a cornerstone of the country's western defense.

The Tank Paradox and the Infantry Gap

When dissecting the land forces, the author presents a complex picture of rapid modernization mixed with significant logistical gaps. The coverage of armored vehicles is particularly compelling. Good Times Bad Times writes, "Warsaw openly argues that it is building the largest and most powerful land army in the EU." They detail how Poland has already received "116 M1 A1 Abrams tanks" and is nearing completion on "250 advanced M1 A2 SCP V3 Abrams among the most capable tanks in the world." Simultaneously, they are integrating South Korea's K2 Black Panther tanks, with plans for local production that could reach 800 units.

This dual-track procurement strategy is a masterstroke of risk management, ensuring that Poland is not dependent on a single supplier. The author notes that the K2PL variant "would mark a return to tank manufacturing in Poland and a long-term investment in the country's defense industry." This is a significant economic and strategic pivot. Yet, the piece is refreshingly honest about the challenges. While the tank fleet is expanding, the situation for mechanized infantry is described as "far more challenging." The author uses a poignant anecdote: "the most common infantry fighting vehicle in the Polish army today is a Yel truck." This stark reality check prevents the narrative from becoming mere techno-optimism.

The gap exists because Poland transferred hundreds of aging BMP-1 vehicles to Ukraine, a move that created an "urgent capability gap at home." Good Times Bad Times writes, "The total number of armored vehicles lost as a result of support for Ukraine may have reached as many as 800 vehicles. That is equivalent of the equipment of roughly 14 mechanized battalions." This is a sobering admission of the cost of solidarity. The replacement program, centered on the domestic Borsuk vehicle, is moving slowly, with full-scale production not expected to ramp up until later this decade. A counterargument worth considering is whether the reliance on foreign platforms like the Abrams and K2 creates long-term logistical vulnerabilities, but the author mitigates this by emphasizing the robust support contracts and the push for domestic ammunition production.

Artillery and the Long Reach

Perhaps the most transformative element of Poland's modernization is its artillery and missile forces. The author highlights a massive shift from Soviet-era systems to a hybrid of domestic and South Korean technology. "Poland continued purchasing crap howitzers, but also ordered nearly 400 Korean K9s," the text explains, noting that the total fleet is expected to reach around 600 systems. This is complemented by the integration of the Polish Topas fire control system, which the author calls "one of the most advanced artillery management systems in the world."

The coverage extends to rocket artillery, where Poland is fielding systems capable of striking targets at ranges of up to 500 km. Good Times Bad Times writes, "Poland is fielding both the well-known Himers and the South Korean K239 Chunma." This long-range capability is the physical manifestation of the "deterrence by punishment" doctrine. The author also points to emerging domestic capabilities, noting that Poland has joined a European program to develop a land-based equivalent of the Tomahawk missile. This is a bold move, signaling a desire for strategic autonomy.

"In modern warfare, raw quantities alone do not tell the full story. But while the armed forces are rapidly strengthening, the situation in mechanized infantry remains far more challenging."

The author's analysis of the drone program adds another layer of depth. Poland is acquiring over 1,600 Fly Eye reconnaissance drones and operating MQ-9 Reapers, which provide "precision strike capabilities against ground targets." The inclusion of the K239 Chunma and the potential for domestic cruise missiles suggests a force structure designed for deep interdiction, not just frontline defense. This aligns with the historical precedent of the 11th Armoured Cavalry Division, which has always been tasked with rapid, mobile operations, now updated for the drone age.

Bottom Line

The strongest part of this argument is its unflinching look at the trade-offs: Poland is sacrificing immediate infantry capacity to build a world-class armored and artillery force capable of deep strikes. The biggest vulnerability lies in the timeline; the gap between the transfer of equipment to Ukraine and the arrival of new domestic systems leaves a window of exposure. Readers should watch for the execution of the K2PL production contracts and the ramp-up of the Borsuk infantry fighting vehicle program, as these will determine whether the ambition can match the reality. This is not just a military buildup; it is a fundamental restructuring of European security.

Does a nation's security have a price? Yes, about $450 billion by 2035. That's how much Poland plans to spend on defense according to a Deoid report, roughly half of its current annual GDP. These for a medium-sized European country are enormous sums.

But after more than a decade of war just across Poland's eastern border in Ukraine, few people in the country see this spending as excessive in the face of renewed Russian aggression. It is widely viewed as necessary. But what does this money actually buy? What capabilities does Poland have today?

And what is it trying to build? That's why we decided to take a closer look at what is arguably the largest military modernization effort in Europe to assess what Poland has now and what it is expected to field in the years ead. By 2035, the Polish armed forces aim to operate across all domains, land, air, sea, cyber, and space with the ability to strike deep behind enemy lines. But will it be enough to stop a potential Russian invasion?

In this episode, we break it down. Poland is increasing its defense spending to 5% of GDP. It's modernizing its fleet, purchasing new military equipment, and expanding its domestic defense industry. This trend is spreading globally, bringing multi-billion euro contracts to specific companies positioned to benefit.
