Weapons of Ukrainian Victory: M113 armored personnel carriers

-

The Armed Forces of Ukraine will soon receive the legendary American M113 armored personnel carriers. Today we will talk about them in detail.

Our Western partners are constantly trying to help Ukraine in the fight against hordes of orcs who brazenly seized our territories, shelling and destroying our cities and villages, killing civilians, looting and bullying Ukrainians. But the enemy receives a decent response and suffers heavy losses in manpower and equipment. And all this thanks to the timely help of Western partners, for which we are all very grateful.

Recently, there was a report that the US Department of Defense and the Danish government have decided to provide Ukraine with modernized models of the legendary M113 armored personnel carrier, which has proven itself well. The statement said that the Indiana National Guard had prepared a number of M113 armored personnel carriers for transfer to the Armed Forces of Ukraine as part of a US initiative to support Ukraine in defending itself against Russian invasion. That is, the number of armored personnel carriers that will be transferred is still unknown, but they will soon be in the service of the Armed Forces.

Let’s take a closer look at these legendary armored vehicles.

What is a M113 APC?

The American M113 armored personnel carrier was developed by FMC (Food Machinery Corp.) based on the M59 and M75 armored personnel carriers of the 1950s. Kaiser Aluminum and Chemical produced the aluminum needed to make the M113 armored personnel carriers. The first prototype M113 was made in 1957. The US Army adopted the vehicle in 1960.

Later, in 1994, FMC moved production of the M113 to its new subsidiary, United Defense. But in 2005, United Defense itself was acquired by BAE Systems, which is now producing the legendary M113.

Over 80,000 M113 armored personnel carriers in various modifications were produced until this day. This equipment is in service in more than 44 countries. Most of the M113s used by the US Army have been upgraded to the M113A3 variant. In 2020, BAE Systems completed the development of the first armored multi-purpose vehicle (AMPV), which will replace the M113 armored personnel carriers, which have been in service since the 1960s. In 2018, the company received an initial contract for the supply of up to 450 AMPV for the US Army. However, the M113, which currently serves the US military, is expected to remain in service until 2030.

Modifications of M113 APC

The vehicle has more than 40 modifications. Basic variants include M113A1, M113A2, M113A3 and M113 ACAV. The same M113A1 was introduced in 1964. It has a diesel engine with 215 hp (160 kW) and is equipped with a M106 mortar.

The M113A2 variant was manufactured in 1979. It has improved cooling and updated suspension. The upgraded M113A3 was introduced in 1987. It has improved battlefield survival, a more powerful engine, an external fuel tank and better protection than the base model. There are also variants of the M113A3, which are equipped with high-speed digital networks and data transmission systems, which allows you to integrate hardware, software and modular kits, such as M113A3s.

Design of the M113 APC

The main feature of the M113 is a completely closed hull, the armor of which is made of aluminum alloy 5083 of aviation quality. This was the first serial armored vehicle to use aluminum armor. Up to 40% of car components are made of light alloys. The aluminum hull has much greater rigidity than steel. This has reduced the number of reinforcing structures and created a more comfortable interior.

The armored personnel carrier was specially designed to provide protection not only from light firearms, but also from fragments of artillery shells. M113 was created as an armored personnel carrier, which could transport an infantry unit to the combat zone, quickly disembark fighters, and then retreat to the rear, thus full protection for soldiers in combat conditions was not meant by the concept.

M113

The 12.3-ton armored personnel carrier is 4,863 m long, 2,686 m wide and 2.5 m high. It can accommodate three crew members and 11 troops. Boarding and disembarking the troops takes place through the rear ramp. The ramp is equipped with emergency exit doors. In addition, there is another large hatch mounted on the roof above the landing unit.

M113

The M113 has an internal design that has become the standard for most modern armored personnel carriers. The engine compartment is in the front of the hull on the right and the driver’s compartment шы on the left. The middle and back of the hull are occupied by personnel.

The main weapon of the M113 is a 12.7-mm machine gun mounted above the commander’s hatch, used to hit both ground and low-flying air targets, such as helicopters.

Engine and mobility of M113

The first batch of M113 was equipped with a Chrysler 75M petrol engine with 209 hp. It worked in conjunction with the General Motors TX-200 manual transmission. But a modified modern version of the American armored personnel carrier M113 is equipped with a two-stroke six-cylinder 6V53 Detroit diesel engine with a three-speed automatic transmission Allison TX100-1. The vehicle has good mobility on sand, snow and swamp.

M113 is an amphibian. It is able to provide landing of the troops both on land and in the water. The armored personnel carrier moves in the water with the help of caterpillars. The speed of the M113 armored personnel carrier is 67.6 km/h on land and 5.8 km/h in water.

The relatively low weight makes it easy to transport the M113 APC by cargo plane.

What is the best way to use them?

It will be interesting to see how our Armed Forces use the M113. I think it would be best to leave them behind the front line and use for transportation of support personnel such as mechanics and engineers. They can also carry ammunition, food, water and other goods. If they are used on the front line, they should move behind the tanks for better survivability. Anti-tank mines can be a problem for light alloy hulls. The APC can be used as part of a rapid reaction force. Such an armored vehicle could quickly land troops at various points during combat. But light armor cannot withstand tanks and artillery shells in the middle of the battlefield.

Despite its age, the M113 is a desirable addition to the Ukrainian arsenal. They can be used for combat support, evacuation of the wounded or transportation of explosive ordnance. The M113 armored personnel carrier is a classic, and any help is now paramount.

Each such armored personnel carrier brings our Victory closer. And she definitely will! We believe in our Armed Forces! Glory to Ukraine! Death to enemies! Orcs, burn in hell!
