Introduction
The T-90 is a third-generation main battle tank (MBT) developed by Russia. It represents a blend of the robust design principles from the Soviet era and modern technology. Since its introduction in the 1990s, the T-90 has become the backbone of armored forces in Russia and several other countries, known for its firepower, protection, and mobility.
Development and Design
The T-90 was developed by Uralvagonzavod in the late 1980s and early 1990s as an improvement over the T-72 and T-80 tanks. Its design incorporated lessons learned from past conflicts and advancements in technology.
Key design features include:
- Composite Armor: Enhanced with Kontakt-5 explosive reactive armor (ERA) to provide superior protection against kinetic and chemical energy projectiles.
- Low Profile: The tank’s design minimizes its silhouette, making it harder to detect and target.
- Autoloader: The T-90 is equipped with an autoloader system for its main gun, reducing the crew size to three and improving the rate of fire.
Armament
The T-90’s armament is designed to engage a variety of targets, including enemy tanks, infantry, and fortifications:
- 125mm Smoothbore Gun: The primary weapon, capable of firing a range of ammunition types, including armor-piercing fin-stabilized discarding sabot (APFSDS) rounds, high-explosive anti-tank (HEAT) rounds, and anti-personnel rounds.
- AT-11 Sniper Guided Missiles: Launched from the main gun, these missiles can engage targets at greater distances with high precision.
- Secondary Armament: Includes a 7.62mm coaxial machine gun and a 12.7mm anti-aircraft machine gun, providing additional firepower against infantry and low-flying aircraft.
Mobility
The T-90 is designed to operate in diverse terrains and climates, showcasing impressive mobility:
- Engine: Powered by a V-92S2 diesel engine, producing 1,000 horsepower, enabling the tank to reach speeds up to 60 km/h (37 mph) on roads and 45 km/h (28 mph) off-road.
- Range: With external fuel tanks, the T-90 can achieve an operational range of around 550 kilometers (340 miles), making it suitable for extended operations without frequent refueling.
- Suspension: Equipped with a torsion bar suspension system, providing a smooth ride over rough terrain and enhancing crew comfort and vehicle stability.
Protection
Protection is a critical aspect of the T-90’s design, ensuring crew survivability and vehicle resilience in combat:
- Composite Armor and ERA: The combination of passive armor and reactive armor increases the tank’s resistance to various threats.
- Shtora-1 Countermeasure Suite: An advanced electronic countermeasure system designed to disrupt enemy laser targeting and guidance systems, reducing the effectiveness of anti-tank guided missiles (ATGMs).
- NBC Protection: The T-90 is equipped with a nuclear, biological, and chemical (NBC) protection system, allowing the crew to operate in contaminated environments.
Variants and Upgrades
Over the years, the T-90 has seen several variants and upgrades to enhance its capabilities:
- T-90A: Features a welded turret, improved ERA, and a more powerful engine.
- T-90S: An export version with customized features based on the client’s requirements.
- T-90MS Tagil: The latest variant, featuring advanced fire control systems, digital communication systems, improved armor, and a new automatic loader.
Operational History
The T-90 has been deployed by various countries and has seen combat in several conflicts:
- Russian Army: The primary user, with the T-90 forming a significant part of Russia’s armored forces.
- Indian Army: India is one of the largest operators of the T-90, locally producing it under license as the T-90 Bhishma.
- Syrian Civil War: The T-90 has been used by Syrian government forces, demonstrating its capabilities in urban and desert warfare.
Global Influence
The T-90’s design and performance have influenced tank development globally. Countries like India have not only adopted the T-90 but also incorporated its design elements into their indigenous tank programs. The T-90’s success has also prompted other nations to develop or upgrade their own main battle tanks to keep pace with modern armored warfare requirements.
