Cold War Firepower Reborn: How Ukraine’s Acquisition of the M110 Howitzer Could Shift the Battlefield

In a development that has drawn significant attention from military analysts, Ukraine has quietly deployed a Cold War‑era weapon system that many experts believe could have an outsized impact on the ongoing conflict with Russia. The weapon in question is the 203‑millimeter M110 self‑propelled howitzer, a system developed decades ago by the United States that is now in service with the 52nd Artillery Brigade of the Ukrainian Armed Forces.

While the M110 itself is not a modern digital system like the U.S. Army’s 155‑millimeter M109 Paladin, its sheer firepower and range—combined with a large stockpile of compatible ammunition—could help fill a capability gap on Ukraine’s artillery front. For a conflict that has become, in many respects, a grinding artillery duel reminiscent of mid‑20th‑century warfare, the arrival of the M110 is being viewed by some observers as a potential game changer.

An Unexpected Addition to Ukraine’s Arsenal

The first question for many analysts was simple: how did Ukraine obtain a weapon that the U.S. military long ago retired? The answer lies in an October 2025 agreement in which Greece approved the transfer of 60 U.S.‑made M110 howitzers to Ukraine, along with tens of thousands of rounds of ammunition. The deal, valued at an estimated €199.4 million (about $230 million), also included sets of Zuni rockets compatible with the howitzers.

The artillery and associated ammunition were to be shipped to Ukraine via Czech Republic, with no requirement for refurbishment or modification—a significant logistical advantage. The ease of transfer suggests that, although the M110 is an older system, many of the units Greece had in reserve were still in serviceable condition.

According to military tracking sources, Greece once operated approximately 145 M110s from the early 1980s forward. The 60 units now slated for transfer to Ukraine represented only a portion of Greece’s inventory, with the systems largely considered surplus as Athens modernized its artillery capabilities to NATO standards.

For Ukraine, the acquisition offered an opportunity to boost its long‑range firepower with a system capable of delivering massive explosive payloads at distances exceeding 30 kilometers (about 18 miles). While the weapon’s design hails from an earlier era, its impact on the battlefield could be significant.

The M110: Power and Limitations

The M110’s design is straightforward: a tracked chassis equipped with a large‑bore howitzer capable of firing 203‑millimeter rounds that weigh roughly 90 kilograms (about 198 pounds) each. Unlike more modern self‑propelled artillery systems, the M110 does not depend heavily on digital fire‑control suites or networked targeting systems. Instead, it relies on brute force, mobility, and sheer shell weight to affect targets.

Because each unit carries only two rounds internally, doctrine calls for a dedicated support vehicle to accompany the gun crew, typically carrying the remainder of the ammunition. This requires a substantial troop commitment: up to 13 personnel per system, including loaders, drivers, and command staff.

That higher personnel requirement is part of why the M110 is not ideal for highly mobile, small unit operations. It is best suited to deliberate fire missions against static targets—command centers, supply depots, fortifications, and concentrations of troops or equipment.

Even so, the weapon brings value that Ukrainian forces have lacked at scale: heavy, long‑reach artillery capable of delivering destructive firepower into Russian rear areas that smaller 155‑millimeter guns may struggle to reach.

Ammunition Stocks: A Force Multiplier

The importance of the M110 extends beyond the guns themselves. As part of the Greek transfer, Ukraine received a substantial stockpile of compatible ammunition, including:

50,000 high‑explosive M106 rounds
40,000 rocket‑assisted M650 rounds (for extended range)
30,000 M509A1 dual‑purpose improved conventional munitions (DPICM)
30,000 M404 improved conventional munitions

That inventory gives Ukraine not just range, but versatility. High‑explosive rounds are useful against fortified positions and infrastructure; rocket‑assisted shells extend the weapon’s reach; and DPICM rounds scatter submunitions over a target area, increasing lethality against troop formations or light vehicles.

The volume of ammunition Ukraine now fields with the M110s allows the weapon to serve as a sustained fire platform rather than a short‑lived novelty. In war, logistics often determine success more than technology, and the ammunition transfer gives the Ukrainians a sustainable and potent firepower capability.

How the M110 Fits Into Ukraine’s Firepower Strategy

The 52nd Artillery Brigade, which received the first batch of M110 howitzers, already fields a mix of artillery types tailored to different roles. This includes domestically‑produced systems like the 2S22 Bohdana—designed for rapid, precision fire—and RM‑70 Vampire multiple launch rocket systems, optimized for saturation strikes.

In this layered artillery doctrine:

The Bohdana performs precision strikes at range, ideal for harassing or interdicting key targets.
The RM‑70 Vampire delivers massed rocket fire to shape or disrupt front‑line engagements.
The M110 brings deep, heavy firepower capable of reaching hardened or high‑value rear targets.

Put simply, the arrival of the M110 allows Ukrainian commanders to diversify fire missions, applying the right tool to the right target rather than relying exclusively on smaller, lighter guns.

This approach is particularly valuable in contested sectors such as around Kharkiv and Kramatorsk, where Russian forces have mounted repeated offensives. The M110’s range and explosive weight give Ukraine the ability to strike logistics hubs, artillery concentrations, and troop staging areas before those forces can engage Ukrainian positions.

Could Ukraine Acquire More M110s?

The Greek transfer, while impactful, may not be the end of the story. Sources tracking global inventories indicate that Greece may have another 85 M110s in reserve. Whether those remaining units are in suitable condition for transfer or operational use remains an open question.

Other nations that once operated the M110—such as Spain, Turkey, and Bahrain—could potentially offer additional systems, though political, logistical, and legal constraints would govern any further transfers.

In addition, Ukraine has tools within its own diplomatic and procurement frameworks, such as the Prioritized Ukraine Requirements List (PURL), which allows Ukraine to specify what military aid it most needs. Through PURL, NATO allies can fund purchases directly from the United States for delivery to Ukrainian forces.

The U.S. originally produced roughly 1,100 M110 howitzers after introducing the system in the early 1960s. Many of these were retired in the 1990s, and components such as barrels were repurposed for other munitions. Whether significant stocks of complete M110 systems remain in American storage, and whether they could be repurposed or re‑barreled, is unclear. If so, PURL could provide a route for additional M110 acquisitions.

The Tactical and Strategic Impact

The deployment of the M110s has implications at both tactical and strategic levels.

Tactically, the presence of heavy guns capable of firing nearly 90‑kilogram shells across long distances forces Russian forces to adjust how they stage attacks and position key assets. Concentrations of troops, armored vehicles, and supply depots become far easier targets for Ukrainian long‑range artillery, potentially slowing or attriting Russian offensives.

Strategically, the M110’s firepower gives Ukraine greater leverage in shaping battlefield geometry. In areas where Ukraine has established so‑called “kill zones”—defended sectors combining anti‑tank obstacles, minefields, drones, and layered defenses—heavy artillery increases Ukraine’s ability to turn those zones into lethal engagements for assaulting units.

Instead of simply absorbing pressure at the front line, Ukrainian forces can use artillery to influence where the battles occur, forcing Russian units into exposed areas where massed firepower and long‑range rounds make advances costly.

Limitations and Costs

Despite its firepower, the M110 is not without limitations. At best, a crew can fire two rounds per minute, and crews must carry heavy logistical support for sustained operations. The system is also relatively slow compared to lighter modern guns and requires significant training for Ukrainian artillerymen.

There is also a financial dimension. The €199.4 million Greece‑Ukraine deal included not only the guns but also ammunition and delivery logistics. Based on publicly available pricing data, Ukraine effectively purchased the howitzers at roughly €520,000 (about $599,000) each, with the rest of the cost allocated to ammunition and transport. On a per‑shell basis, the arrangements equate to relatively low costs compared to the strategic value delivered.

Economics aside, using older systems does carry additional maintenance burdens, especially when spare parts are not readily available. Yet for a nation enduring the enormous financial strain of war, the relative cost‑efficiency of the M110’s firepower can outweigh those challenges.

Ukraine’s Evolving Artillery Doctrine

Perhaps the most important implication of the M110’s deployment is what it says about Ukraine’s artillery doctrine. Whereas earlier phases of the war saw Ukrainian forces relying heavily on Western‑supplied 155‑millimeter howitzers and domestic designs, the addition of heavy guns like the M110 suggests a maturing approach that blends old and new capabilities.

In effect, Ukraine is integrating legacy systems into a modern battlefield in ways that accentuate strengths and circumvent weaknesses. The M110, while a product of the Cold War, delivers a specific capability that aligns with Ukraine’s current operational needs: long‑reach, high‑impact firepower to complement precision systems and mobile rocket artillery.

Looking Ahead

As fighting continues along multiple fronts in eastern Ukraine, the presence of M110 howitzers could alter tactical calculations and slow Russian offensives. The weapon’s ability to strike deep into enemy rear areas, combined with Ukraine’s layered defense and forward‑deployed artillery, gives Kyiv greater flexibility and deterrent power.

Whether additional M110s will arrive through further transfers from Greece, other nations, or through programs such as PURL remains to be seen. What is already clear, however, is that a Cold War titan has found new life on the modern battlefield — and in doing so, forced both sides to reassess how artillery firepower can shape the course of conflict.
