The T-100 tank destroyer and T-122 self-propelled gun are examples of how countries adjust to new types of warfare. These vehicles were made from the Soviet T-34-85 medium tank and are well-known in military history. This article examines the history, design, and performance of the T-100 and T-122 and how they played a key role in Egypt’s military operations.

Unveiling the T-100

Egypt's T-100 Tank Destroyer and T-122 Self-Propelled Gun: A Legacy of Soviet Influence

The T-100 also called the T-34/100, was a game-changing invention produced by a state-owned factory in Egypt. It was developed using the Soviet T-34-85 medium tank as its base and was equipped with a modified turret and a World War II Soviet BS-3 (M1944) 100mm anti-tank gun/field gun.

The T-100 stands out for its unique hexagonal turret design, which features sloping sides that add to its visual appeal and provide strategic benefits.

Redefining the Turret


The T-100’s original turret underwent significant modifications to accommodate the impressive BS-3 turret. The rear armor was removed, and angle steel plate extensions were carefully added to expand the turret space. These extensions extended to the front and top of the turret, resulting in a noticeable visual difference from the previous model. These design changes allowed space for the BS-3 and enhanced the turret’s overall functionality.

The Arsenal

The T-100 is equipped with the powerful BS-3 100mm field gun, which is known for its anti-tank capabilities. To ensure effective recoil control, the gun has a double-chamber muzzle brake. The extended barrel with a muzzle brake under the gun root further enhances the vehicle’s combat prowess. 

Moreover, the T-100 has a spherical machine gun mount on its right front and an auxiliary fuel tank at the rear of the side. A barrel marching lock secures the turret and barrel for logistical efficiency during marches.

Combat in the Yom Kippur War

During the Yom Kippur War in 1973, the T-100 emerged as a dominant force with its superior firepower that surpassed the original T-34. However, it fell short in modern warfare due to the absence of crucial equipment like night vision goggles and three-defense systems, making it unsuitable for contemporary combat scenarios. Its armor was also inadequate against modern artillery, limiting its role to defensive ambush operations.

Performance Specifications

For a comprehensive understanding of the T-100, let’s examine its vital performance specifications:

  • Weight: 40 tons
  • Length: 6 meters
  • Width: 3 meters
  • Height: 3 meters
  • Crew: 4 people

The T-100 tank destroyer is equipped with a powerful V-2 12-cylinder diesel engine capable of generating an impressive 493 horsepower. This engine allows the tank to reach a maximum speed of 55 km/h and travel up to 360 kilometers. The T-100 is armed with a formidable BS-3 100mm field gun and a 7.62mm machine gun, making it a versatile and effective force on the battlefield.

The Birth of the T-122


A new project was undertaken by Egypt using knowledge gained from the T-100. They added angle steel plate extensions to the T-34-85 turret, which created a new turret that could hold a Soviet D-30 122mm howitzer. This adaptation gave rise to the T-122, also known as the T-34/122 self-propelled gun.


Egypt’s military technology has shown its adaptability and innovation by creating the T-100 tank destroyer and T-122 self-propelled gun. Both vehicles were developed from the chassis of the Soviet T-34-85 and played important roles in historical conflicts, leaving a lasting impact on military history.

The T-100 boasted increased firepower, while the T-122 introduced a self-propelled artillery aspect to Egypt’s arsenal. These advancements highlight warfare’s constantly evolving nature and adaptability’s significance in maintaining a strong defense.

In conclusion, the T-100 and T-122 are enduring reminders of Egypt’s military prowess and its ability to transform the legacy of Soviet influence into formidable assets on the battlefield.
