The T-90 Tank: A Pillar of Modern Armored Warfare

 
The T-90, a third-generation main battle tank (MBT) developed by Russia in the early 1990s, represents a fusion of Soviet-era design principles and modern technological advancements. As a direct successor to the T-72 and T-80 series, the T-90 was conceived to address the vulnerabilities of its predecessors while maintaining affordability and adaptability. Over three decades, it has evolved into one of the world’s most widely exported tanks, serving as a cornerstone of Russian military power and a symbol of armored warfare innovation.
 
Development and Design Philosophy
 
The T-90 emerged during a tumultuous period for Russia’s defense industry following the collapse of the Soviet Union. To balance cost-effectiveness with combat readiness, engineers modernized the proven T-72B chassis, incorporating lessons from the more advanced T-80U. The result was a tank that retained the T-72’s rugged simplicity but added critical upgrades in survivability, firepower, and electronic systems. This pragmatic approach allowed Russia to mass-produce the T-90 while maintaining compatibility with existing Soviet-era infrastructure.
 
Key Features and Capabilities
 
1. Armament:
The T-90’s primary weapon is a 125mm 2A46M smoothbore gun, capable of firing armor-piercing fin-stabilized discarding sabot (APFSDS) rounds, high-explosive anti-tank (HEAT) projectiles, and even 9M119 Refleks anti-tank guided missiles (ATGMs) with a range of up to 5 km. Secondary armament includes a 12.7mm Kord heavy machine gun and a coaxial 7.62mm PKT machine gun, providing versatility against infantry and light vehicles.
2. Protection:
The tank employs a multi-layered defense system. Its base armor combines steel and composite materials, supplemented by Kontakt-5 explosive reactive armor (ERA) to neutralize shaped-charge warheads. Later variants, such as the T-90M, feature Relikt ERA, which offers enhanced protection against tandem-charge missiles. The Shtora-1 electro-optical active protection system further disrupts incoming anti-tank guided missiles (ATGMs) by jamming their guidance systems.
3. Mobility:
Powered by a V-92S2F diesel engine generating 1,130 horsepower, the T-90 achieves a top speed of 60–65 km/h on roads. Its torsion bar suspension and wide tracks ensure maneuverability in challenging terrain, a critical advantage in Eastern Europe and Central Asia.
4. Fire Control and Sensors:
The 1A45T fire control system integrates a laser rangefinder, thermal imaging sights, and a ballistic computer, enabling accurate targeting day or night. Modern variants like the T-90M boast advanced digital systems, including the Kalina fire control suite and third-generation thermal imagers, narrowing the sensor gap with Western rivals like the M1 Abrams.
 
Variants and Modernization
 
The T-90 has undergone iterative upgrades to remain relevant on evolving battlefields:
 
- T-90A: Introduced in the early 2000s, this variant replaced the original cast turret with a welded one, improving armor protection.
- T-90M “Proryv-3”: The latest iteration (deployed in 2020) features a redesigned turret with modular armor, a remotely operated anti-aircraft machine gun, and compatibility with the 125mm 2A82-1M cannon.
- T-90MS: An export-focused model with a 1,130-horsepower engine, upgraded fire control, and NATO-standard communication systems.
 
Russia has also retrofitted older T-72 and T-80 tanks with T-90-level technologies, such as improved optics and Relikt ERA, demonstrating the platform’s adaptability.
 
Operational Use and Global Impact
 
The T-90 has seen combat in conflicts such as the Syrian Civil War and the Russo-Ukrainian War, where its strengths and weaknesses have been starkly revealed. While its ERA and mobility proved effective in urban engagements, vulnerabilities to modern anti-tank weapons like the Javelin and NLAW highlighted the need for continuous upgrades. Nevertheless, the T-90 remains a popular export: India operates over 1,000 licensed T-90S “Bhishma” tanks, while Algeria, Azerbaijan, and Vietnam have also acquired variants.
 
Comparison with Western Counterparts
 
The T-90’s cost-effectiveness ($4–5 million per unit) contrasts sharply with the $10+ million price tag of the U.S. M1A2 Abrams or German Leopard 2A7. While Western tanks often excel in crew survivability and sensor technology, the T-90 prioritizes simplicity, ease of maintenance, and all-weather reliability—traits valued in resource-constrained militaries.
 
Conclusion
 
The T-90 embodies Russia’s pragmatic approach to armored warfare: blending legacy systems with incremental innovation to produce a versatile and cost-effective MBT. While the T-14 Armata represents the future of Russian tank design, the T-90’s enduring production and upgrades underscore its continued relevance. As hybrid warfare and drone-dominated battlefields reshape modern combat, the T-90’s adaptability ensures it will remain a key player in 21st-century conflicts.

The Unsinkable Battleship

Fort Drum  This is Fort Drum, a concrete battleship built in 1909 named after Brigadier General Richard C. Drum. Originally this was an islet called El Fraile until the Board Of Fortifications chaired by William H. Taft recommended that all key harbors of territories acquired after the Spanish-American War be fortified, which led to the construction of Fort Drum for the defense of Manila and Subic Bay. In 1909, El Fraile Island was first leveled for a massive steel reinforced concrete fortress resembling that of a battleship to be erected. Fort Drum was 350 ft long, 144 ft wide with a top deck of 40 ft high above water at low tide. Over head protection was a 20 foot thick steel reinforced concrete deck with its exterior walls ranging approximately from 25 to 36 ft making it impregnable by enemy naval assault. The first proposal was to equip it with two twin twelve inch (305 mm) guns on top of the fortress but the US War Department decided to change it with fourteen inch (3...

Battleships Yamato And Musashi

Battleships Yamato and Musashi    The Battleships Yamato and Musashi were two huge structures of their kind weighing a total of 72,800 tonnes and 73,000 tonnes respectively when fully loaded. Their main batteries were armed with nine 46 cm 45 Caliber Type 94 naval guns, the biggest gun ever put on a warship. Secondary batteries were with 155 mm guns mounted in four triple turrets (one forward, one aft and two midships), twelve 127 mm guns in six twin mounts (three on each side) and a total of 162 25 mm anti-aircraft guns for Yamato  and 130 25 mm anti-aircraft guns for Musashi. The sister ships were indeed two floating fortresses. Yamato and Musashi were designed and created by the Imperial Japanese Navy to counter their rival in the Asia-Pacific region, the US Navy. Too bad for the Japanese and good for the Americans, these massive structures never lived to their expectations. The battleships were mostly used to transport and escort forces and resources to is...

Russian Alligator

Ka-52  The Russian Ka-52 “Alligator” is a modified version of the single seat Ka-50 “Black Shark” that is specifically created by Kamov as an all-weather attack helicopter and is capable of attacking ground hostiles and low-speed air targets during daytime or at night. Originally, the Kamov proposal was to develop a helicopter dedicated to conduct battlefield reconnaissance, provide target designation, support and co-ordinate group attack helicopter operations. However, the economic hardship that struck Russia in the late 1980's prompted the Kamov’s Designer General to install the reconnaissance and target designation system in the modified Ka-50. Ka-50 Now designated as Ka-52 “Alligator” (NATO reporting name Hokum B), the new version was fitted a side-by-side seating arrangement, giving an extra seat for the second crew that has the task of operating the optronics/radar reconnaissance system, a radar system with two antennas—mast-mounted for aerial targets and nose-mo...
