The ‘Skif’ Armoured Personnel Carrier

Today we examine the new tracked armored personnel carrier “Skif,” developed by UkrArmoTech. The platform warrants a closer look.

Ukraine’s defense industry continues to evolve under wartime conditions, with ongoing efforts to improve equipment for frontline use. The introduction of the tracked APC “Skif,” developed on the basis of the M113, has attracted attention in this context. The vehicle is reported to incorporate enhanced protection aligned with STANAG 4569, along with a modified hull design and improved mine resistance. The following sections review these characteristics in a measured and technical manner.

Why tracks instead of wheels?

Before discussing the vehicle itself, it is useful to clarify why a tracked APC configuration was chosen. Wheeled platforms are generally less expensive, offer higher speeds on paved roads, and are typically easier to maintain. Platforms such as the Stryker demonstrate that wheeled armored vehicles can be operationally effective in many scenarios. However, the selection between tracked and wheeled mobility is primarily driven by terrain, mission profile, and survivability requirements rather than cost or road performance alone.

However, operational context significantly alters this assessment. Ukrainian terrain – particularly during spring and autumn – often consists of waterlogged soil with low load-bearing capacity. Under such conditions, wheeled vehicles can experience reduced mobility or become immobilized. Tracked platforms, by contrast, distribute weight more evenly and provide improved traction on soft or heavily degraded surfaces. This makes them more suitable for movement across muddy fields, damaged rural roads, and urban areas affected by destruction. For these reasons, the requirement for tracked APCs within the Armed Forces of Ukraine remains consistent. The development of such a platform by UkrArmoTech reflects this operational need.

Why was the M113 chosen as the base platform?

Before analyzing the “Skif” itself, it is important to understand why the developers selected the M113 as the foundation. This platform is not new: it was introduced in the early 1960s and has seen extensive use in conflicts ranging from Vietnam to the Middle East and beyond.

However, this long service history is also a key advantage. The M113 is one of the most widely produced armored platforms in history, with over 80,000 units manufactured and operated by more than fifty countries. In practical terms, this translates into broad availability of spare parts, components, and technical expertise. In a high-intensity operational environment, maintainability is not merely a matter of convenience – it directly affects vehicle availability, crew safety, and overall unit effectiveness.

In addition, the design of the M113 has been validated through decades of operation across a wide range of environments – from tropical climates to arctic conditions. Using such a platform as a base and applying targeted modernization is not an indication of limited ambition, but rather a pragmatic engineering approach. This is particularly relevant in situations where time constraints and resource availability play a decisive role.

What is UkrArmoTech and why consider it a credible developer?

UkrArmoTech has established a position as a developer focused on adapting armored platforms to current operational requirements rather than simply extending legacy designs. Within the segment of armored vehicles and tactical platforms, the company has demonstrated a consistent approach to engineering execution and project completion. Its work tends to emphasize practical, deployable solutions rather than limited demonstrator prototypes, which is a relevant factor in assessing credibility in a defense context.

The “Skif” project represents the most ambitious effort to date for UkrArmoTech. It is not a limited upgrade of individual subsystems, but a comprehensive transformation of the platform – effectively creating a new vehicle based on a well-established chassis.

This approach enables a combination of proven reliability with updated battlefield requirements, including improved survivability, enhanced protection concepts, modern electronics, and the ability to integrate different combat modules.

The internal layout has been revised, with adjustments to optimize space for both crew and dismounts, while also allowing for future upgrades. In a context where equipment must adapt quickly to evolving tactics and threats, this type of modularity becomes a practical requirement rather than an optional feature.

Based on available information and preliminary assessments, the project appears to be executed at a solid technical level. The “Skif” is positioned not as a compromise between legacy and modern systems, but as a considered engineering solution with potential relevance both for the Armed Forces and, potentially, for export markets where cost, reliability, and operational effectiveness are key factors.

Skif APC design

Turning to the technical aspects, the “Skif” features a welded, box-shaped armored hull with sloped frontal armor. The layout follows a conventional scheme that has been refined over decades.

The powerpack – engine and transmission – is located at the front, followed by the crew compartment. The troop compartment occupies the central and rear sections of the hull. Infantry dismounts via a rear ramp, which also includes an auxiliary door.

This configuration improves the relative safety of dismounting personnel, as the front-mounted engine compartment provides an additional layer of protection during egress. The overall design does not introduce unconventional solutions, but reflects established and functionally justified engineering choices.

The crew consists of three personnel: driver, commander, and gunner-operator. The troop compartment is designed to carry up to eight dismounts, with seating arranged along the sides of the hull. Depending on configuration, the combat weight can reach approximately 15 tonnes. The vehicle is powered by a diesel engine with an output in the range of 350–360 horsepower. The running gear is tracked, with a front drive sprocket and five road wheels per side, reflecting a layout consistent with the base M113 platform.

This means that the key elements of the chassis and the powertrain from the M113 have been retained. On one hand, this simplifies logistics and maintenance; on the other, it allows the use of existing spare parts and established repair expertise already available in Ukraine. Maintenance crews familiar with the M113 can transition to servicing the “Skif” without extensive retraining, which is a significant operational advantage under wartime conditions.

At the same time, the vehicle’s hull has undergone substantial redesign. The prototype uses an aluminum structure similar to the original platform, but there are indications that future production versions may transition to armored steel. This is a notable point with implications for protection and durability.

Externally, the “Skif” is distinguishable by a more robust hull, reinforced armor panels, and revised protective geometry.

Protection: the most critical aspect

At the modern battlefield, the most important factor is crew and troop survivability. In this regard, the “Skif” offers a clearly defined protection concept.

The frontal arc of the vehicle is designed to meet STANAG 4569 Level 4. In practical terms, this corresponds to protection against 14.5 mm armor-piercing rounds. This caliber is typically associated with heavy machine guns commonly used on armored platforms, and the stated level indicates resistance against direct frontal engagement from such weapons.

From a technical standpoint, this represents a significant protection threshold for a vehicle in this weight class.

The side and rear protection is rated at STANAG 4569 Level 3, providing resistance against 7.62 mm armor-piercing rounds. While this is lower than the frontal protection level, it reflects standard design practice for armored personnel carriers, where the highest protection is concentrated in the most threat-exposed arc.

A separate and increasingly important aspect is mine protection. Combat experience in Ukraine has demonstrated that mines and FPV drones are among the most significant threats to armored vehicles. The “Skif” incorporates reinforced underbody protection and structural strengthening designed to withstand detonations beneath the tracks and directly under the hull. The actual effectiveness of this protection will need to be confirmed through testing, but its inclusion indicates that the designers have prioritized this threat category.

This also brings back the discussion of material choice between aluminum and steel armor for production models. Aluminum armor reduces weight, but in blast scenarios it has known drawbacks, including poor thermal behavior and structural deformation. This issue has been documented historically, including during the Vietnam War, where the M113 earned a negative reputation in some combat conditions due to these characteristics.

A potential transition to steel armor in production versions of the “Skif” could improve survivability in mine-heavy environments, albeit at the cost of increased mass.

In addition, future upgrades may include add-on armor screens and anti-drone systems. While the exact configuration has not been disclosed, the intent to address unmanned aerial threats is consistent with current battlefield requirements, where FPV drones have become a major risk factor even for heavily armored vehicles.

At the same time, it is important to remain realistic. Like all armored personnel carriers in its class, the “Skif” remains vulnerable to anti-tank weapons and guided munitions. Its armor is designed primarily to protect against small arms fire and fragmentation, not against RPGs or anti-tank guided missiles. This is not a specific limitation of this platform, but a general characteristic of the category.

Armament and electronics: planned configuration

The prototype is currently unarmed, with only smoke grenade launchers mounted on the front of the hull. A roof-mounted interface is provided for a remotely operated weapon station capable of supporting machine guns up to 14.5 mm caliber.

Details of the onboard electronic suite have not yet been disclosed by the developers. From an engineering perspective, this lack of information limits the ability to assess the vehicle’s full combat potential, since modern battlefield effectiveness is often heavily dependent on sensor integration, situational awareness systems, and digital fire control rather than armor alone.

It is already confirmed, however, that future versions are expected to include remote weapon stations. This is a standard requirement for modern armored personnel carriers, as it allows the crew to engage targets while remaining fully protected within the armored hull.

In addition, the integration of electronic warfare systems and counter-unmanned aerial vehicle measures has been announced. This aligns with current operational realities, where FPV drones have become one of the most significant threats to armored platforms. As a result, even baseline anti-drone capabilities are increasingly considered essential rather than optional for vehicles operating in contemporary combat environments.

Advantages and a candid note on limitations

It would be misleading to discuss only the advantages without acknowledging the limitations, so the following overview aims to be balanced.

The main advantage of the “Skif” APC lies in the combination of a proven, reliable platform with an upgraded level of protection. The vehicle does not require the deployment of an entirely new logistical infrastructure. In units already experienced in operating the M113, the “Skif” APC can be integrated without significant adaptation. The enhanced armor protection also improves survivability compared to the original M113 and many other armored personnel carriers currently in service with the Armed Forces of Ukraine.

The tracked chassis is another important advantage for Ukrainian operating conditions. Unlike wheeled vehicles such as the Stryker, tracks perform significantly better on damaged roads, waterlogged fields, and in off-road terrain typical of Ukraine’s black soil regions, especially during spring and autumn.

At the same time, certain nuances should be acknowledged. The “Skif” APC remains a deep modernization of a 1960s-era platform rather than a clean-sheet design. Some inherent structural limitations of the base vehicle therefore persist. The extent to which these constraints can be mitigated will depend on how effectively engineers at UrkArmoTech address them in the production configuration, particularly in relation to the transition to armored steel and the integration of modern electronic systems.

Why this matters for Ukraine

The answer is straightforward. The Ukrainian Armed Forces require a large number of armored vehicles, and they are needed immediately. Procuring new vehicles abroad is both time-consuming and expensive. Upgrading the existing fleet of M113 vehicles, of which Ukraine has a significant number, is a faster, more cost-effective, and more practical approach.

The new “Skif” APC is positioned within this approach: it builds on existing assets and aims to significantly improve their effectiveness and survivability.

If UrkArmoTech succeeds in bringing the vehicle into serial production with the intended specifications, the “Skif” APC could become a meaningful component of Ukrainian armored units. It is not intended to replace modern Western armored personnel carriers, but rather to serve as a reliable, affordable, and adequately protected infantry transport platform in a category where shortages remain persistent.

The Ukrainian defense industry has demonstrated an ability to respond to the demands of modern warfare. Over the past year, UkrArmoTech alone delivered approximately 400 armored vehicles of its own production to the defense ministry. This indicates that the company is capable not only of design work but also of sustained manufacturing. Production capacity exists, and customer-side funding is also in place. The “Skif” APC represents another example of this development. The next stage is serial production and validation through testing under real operational conditions.

We believe in our engineers just as much as we believe in our defenders. Glory to the Armed Forces of Ukraine! Glory to Ukraine!
