Ukraine’s M113-Inspired Armored Personnel Carrier In Testing

Ukraine has begun testing a new homegrown armored personnel carrier, a tracked vehicle named Skif (Scythian, an ancient warrior tribe that also lived in parts of modern Ukraine). The development underscores the fact that, despite extensive losses of legacy tracked APCs, this is a class of vehicle that the Ukrainian Armed Forces still prioritizes as it tries to hold off the Russian invasion.

According to reports, UkrArmoTech has begun factory testing a prototype of the Skif, which has apparently been developed in direct response to the requirements of the Ukrainian Armed Forces, drawing from lessons learned since the full-scale Russian invasion in February 2022.

UkrArmoTech is among the leading developers and manufacturers of armored vehicles for the Ukrainian Armed Forces, but has, to date, focused on wheeled models such as the Desna, Gyurza, and Tisa. With that in mind, the Skif marks a new direction for the company.

“First and foremost, we relied on our contacts with the military, our understanding of their needs, and our experience with the use of wheeled vehicles on the battlefield,” UkrArmoTech CEO Gennadiy Khirgiy told the Ukrainian Defense Express website. “Active combat operations in Ukraine have demonstrated the need for a significant number of armored vehicles to ensure and maintain the mobility of units and formations of the Armed Forces and Defense Forces.”

The design of the Skif is heavily influenced by the U.S.-developed M113, a Cold War-era tracked APC, many hundreds of which have been supplied to Ukraine since February 2022.

Despite its age, it seems the M113 has been a success in Ukrainian hands, offering a useful combination of reliability, maintainability, troop-carrying capacity, and off-road mobility.

The designers of the Skif were therefore instructed to produce a vehicle that matched the M113’s mobility while improving on its levels of protection and firepower.

According to reports, the Skif makes use of off-the-shelf components and assemblies from foreign manufacturers involved in the production of armored vehicles that are “descendants” of the M113.

It’s unclear if this implies that the Skif uses components from Western manufacturers that have built the M113 and its derivatives, or if the Ukrainian vehicle employs parts from other Western-made APCs. Noteworthy is the fact that members of the broader M113 family have been built under license in Belgium, Germany, Italy, the Netherlands, and Turkey, as well as several other countries outside Europe.

Reportedly, 60 percent of the vehicle’s components will initially be imported, and these will include the engine, transmission, suspension components, transfer case, and tracks. If production is launched, an increasing proportion of the components will be made locally.

In its basic form, the Skif is intended to transport soldiers from mechanized units across the battlefield and to provide them with fire support. As well as three crew (driver, commander, and gunner), located in the front section behind the power module, the Skif can accommodate eight soldiers in the rear troop compartment. The troops enter and exit via a rear ramp, as on the M113.

The prototype of the Skif has an aluminum hull, reportedly the first time this has been used on a Ukrainian combat vehicle. However, a series-production version will likely feature an armored steel. While steel offers better ballistic resistance and is easier to repair in the field, it comes with a significant weight penalty.

With the aluminum hull, the Skif weighs around 15 tons and is driven by a 360-horsepower diesel engine. The modular design means that different engines can be installed, for example, if more power is needed for a steel hull, or when fitted with heavier weapons.

In its basic form, the Skif has a Ukrainian-made remotely controlled combat module on the hull roof. This can be armed either with a 12.7mm or 14.5mm heavy machine gun paired with a 7.62mm auxiliary machine gun. As seen in the photos, the prototype does not currently have the combat module fitted.

Armor protection is in line with NATO STANAG 4569 Level 4 over the frontal section (withstanding, for example, 14.5mm machine gun fire, or a 155mm artillery projectile detonating at 25 meters), and Level 3 on the sides and rear (resistant to 7.62mm gunfire, or a 155mm artillery projectile detonating at 60 meters). Mine protection below the hull is rated at Levels 3a and 3b. The vehicle is expected to withstand the detonation of around 13 pounds of explosives under the hull or tracks.

It’s unclear what kinds of protection are provided against the threat of attack drones, but some type of electronic warfare gear is included; it would also be expected that the vehicle receives a purpose-designed ‘cope cage’ of the kind that has appeared on most Ukrainian and Russian combat vehicle types during the conflict. Otherwise, the Skif is equipped with communications, navigation, situational awareness, and fire-control systems of Ukrainian origin. A bank of smoke grenade launchers is fitted across the front of the hull on the Skif prototype.

The Kastuś Kalinoŭski Regiment is a group of Belarusian opposition volunteers, which was formed during the Russian-Ukrainian war to defend Ukraine against the Russian invasion in 2022. The unit is armed with armored personnel carriers: the US M113 and the British FV103 Spartan. All vehicles are equipped with protection against drones. The main task is logistics on the front line: delivering soldiers to the front line, rotating groups and transporting ammunition. This vehicle also takes the wounded from the battlefield directly under heavy enemy fire. (Photo by Sushchyk Kanstantsin/Global Images Ukraine via Getty Images)

The modular design means that the Skif can be adapted for other missions. These are likely to include vehicles equipped for command and control, reconnaissance, anti-armor, mortar carrier, medical evacuation, and more.

With the continued debate over wheeled versus tracked combat vehicles, it is interesting to note that Ukraine, after focusing on the local production of wheeled fighting vehicles, continues to see the necessity for tracked APCs. While heavier, more complex, and more costly, they are better able to deal with the brutal mud that is a feature of Ukrainian winters. They are also generally better in terms of armor protection.

Ukrainian officers of the 4th Company, 1st Battalion, 82nd Separate Air Assault Brigade say that this American military hardware has been crucial to their ability to cross into Russia last August, as well as to Ukraines border defense against Russias all-out invasion in February 2022. Senior Ukrainian commanders and officials have expressed concern that deep U.S. military and financial support will ease up or stop with the incoming Trump Administration, which has stated that it would swiftly end the three-year war.

For that reason, the aging M113 and the Soviet-era MT-LB remain popular choices for the Ukrainian Armed Forces.

According to the Oryx open-source tracking group, since the start of the current conflict, more than 500 Ukrainian M113s and more than 150 MT-LBs have been confirmed destroyed or damaged. The actual figures are certainly higher, as Oryx only tallies losses that are confirmed with visual evidence.

Despite the need for a vehicle in this class, there remain significant challenges in getting it into production. Very likely, Ukraine will have to rely heavily on foreign funds and expertise if it is to put the Skif into quantity production. Should that prove realistic, Ukraine will likely also seek to sell the Skif to foreign customers, too.

Continued factory testing of the Skif prototype should provide a practical assessment of the new platform’s design maturity, including whether its mobility and running performance meet local requirements. Certainly, the new tracked APC is a bold venture for Ukraine’s war-ravaged industry, but it represents a class of vehicle for which there is a near-insatiable local demand.
