Shenyang J-35 and its development history

The Shenyang J-35 is a Chinese-made fifth-generation multirole stealth fighter jet manufactured by Shenyang Aircraft Corporation (SAC). This twin-engine aircraft is designed for air superiority, surface attack, and modern cyber warfare missions. The J-35's presence makes China the second country in the world after the United States to operate two types of stealth fighter jets simultaneously (along with the Chengdu J-20).

The Shenyang J-35's development history began with an independent project called the Shenyang FC-31 "Gyrfalcon," which first flew in 2012. Unlike the majority of Chinese defense equipment, which is fully funded by the military from the outset, this aircraft was initially a private investment project of Shenyang Aircraft Corporation (SAC). This decision was taken after SAC lost to Chengdu Aircraft Industry Group in the J-XX project tender (which later gave birth to the J-20 fighter jet).

The chronology of its development evolution is divided into the following key phases: 

1. FC-31 Early Prototype Era (2012–2016)

First Flight (2012): The first prototype (No. 31001) successfully made its first flight on October 31, 2012. During this phase, foreign media often referred to it as the J-31.

Export Market Target: Since it had not yet been officially adopted by the Chinese military, the FC-31 project was initially targeted as an economical stealth fighter for the export market, targeting countries that did not have access to the F-35 from the United States.

Design Update (2016): A second, more aerodynamic version of the prototype was flight tested in December 2016, featuring improvements to the wing, radar system, and a reduced radar cross section.

2. Naval Adoption and Transformation into the J-35 (2020–2021)

Military Interest: The People's Liberation Army Navy (PLAN) sees great potential in the FC-31 platform as a carrier-based stealth fighter. This project officially received state funding and changed its code name to J-35. Maritime Modification (2021): On October 29, 2021, the navalized variant successfully made its maiden flight. This version brings major changes, such as a reinforced landing gear structure for extreme landings on ship decks, arresting hooks, and folding wings to save space in aircraft carrier hangars. 

3. Land Variant Expansion and Mass Production (2023–2025)

Return of the Land Variant (2023): After being successfully optimized for the sea, the Chinese military decided to create a land-based variant for the PLAAF. This variant, without heavy maritime components, first flew in September 2023. Public Debut & Mass Production (2024–2025): In November 2024, the Air Force variant was officially introduced to the public under the name J-35A at the Zhuhai Airshow. Entering mid-2025, the SAC assembly line showed that this aircraft had entered the mass production stage. In September 2025, the J-35 officially made its military parade debut alongside the J-20.

4. Full Operationalization and Official Designation (2025–2026) Electromagnetic Catapult Test: The J-35 made history as the world's first stealth fighter jet to operate using the catapult electromagnetic launch (CATOBAR) system on the Fujian aircraft carrier. Designation "Blue Shark" (2026): In April 2026, Shenyang Aircraft Corporation officially confirmed the operational designation for the carrier variant, "Blue Shark" (蓝鲨 - Lan Sha), signifying the jet's full readiness to strengthen China's far-sea fleet.

Centauro II, the Tank Hunter

The Centauro II is an armored fighting vehicle manufactured by IDV (Iveco Defence Vehicles) through a consortium with the defense company Leonardo, known as Consorzio Iveco - Oto Melara (CIO).

Role of IDV (Iveco Defence Vehicles) Chassis and Engine: IDV is fully responsible for the development of the chassis, engine (powerpack), transmission system, and hull of this armored vehicle. Powerful Engine: This vehicle is powered by an IDV-made engine capable of producing more than 720 HP. Defense Consortium: IDV supplies the 8x8 wheel drive platform, while its consortium partners (Leonardo/Oto Melara) provide the weapon system and turret. Centauro II Main Specifications Wheel Configuration: Uses an 8x8 wheel drive system that provides high mobility in various terrains. Main Armament: Equipped with a third-generation 120 mm / 45 mm caliber cannon that has a destructive power equivalent to a main battle tank gun. Combat Function: Operates as a tank hunter (tank destroyer) and heavily armed reconnaissance vehicle. 

Main Users: This vehicle is officially used by the Italian Army and has also been selected in the Brazilian Army's modernization program to replace their EE-9 Cascavel fleet. The Centauro II is a modern evolution of the world's first wheeled tank threat. This vehicle combines the high mobility of an 8x8 wheeled platform with the firepower of a heavy-caliber main battle tank (MBT).

Development History: Roots of the Cold War Conflict (1980s): The predecessor of this vehicle, the Centauro B1 (Centauro I), was designed in the late 1980s for the Italian Army. The goal was to create a highly mobile vehicle to defend Italy's coastal and inland areas from potential Warsaw Pact invasions, armed with a 105 mm cannon. Modernization Needs (2010): Entering the modern era, battlefield threats have changed with the widespread use of IEDs (improvised explosive devices), advanced land mines, and thicker modern tank armor. In 2010, the Iveco - Oto Melara (CIO) Consortium began developing its successor. Premiere (2016): The Centauro II prototype was officially unveiled to the public in June 2016 at the Eurosatory international defense exhibition in Paris, France. Mass Production: In 2018, the Italian Ministry of Defense signed a preliminary contract for the procurement of Centauro II units to gradually replace the aging Centauro B1 fleet. To date, the Italian Army has ordered up to 150 units. In late 2022, Brazil also selected the Centauro II to modernize its cavalry.

USS Carl Vinson (CVN-70)

 USS Carl Vinson (CVN-70) is the third Nimitz-class nuclear-powered aircraft carrier in the United States Navy.

Brief History

Origin of Name: Named in honor of Carl Vinson, the figure dubbed the "Father of Two Ocean Navies." He became the first person in modern U.S. history to have his name attached to an aircraft carrier while he was still alive. 

Launch and Initial Commissioning: Began construction by Newport News Shipbuilding in 1975, launched in 1980, and officially entered active service with the U.S. Navy in 1982. Maiden deployment was carried out in 1983. 

Modernization: Between 2005 and 2009, the ship underwent a Refueling and Complex Overhaul (RCOH) process. This process includes nuclear refueling and upgrading radar and weapons systems so that the ship's service life can reach 50 years. 

Important Operations: Actively involved in various major military operations such as Operation Desert Strike, Operation Southern Watch, Operation Enduring Freedom, and Operation Iraqi Freedom. In 2011, the USS Carl Vinson was the location for the sea burial ceremony for Al-Qaeda leader Osama bin Laden, before his body was thrown into the Arabian Sea. Became a symbol of military diplomacy, including making a historic visit to Vietnam in 2018 (the first US aircraft carrier visit since the end of the Vietnam War). 

Popular Culture: The deck of this aircraft carrier was once used as a filming location for the iconic military aviation film, "Top Gun" (1986) starring Tom Cruise. Until now, the USS Carl Vinson remains active under the command of the US Pacific Fleet to maintain security stability in the Indo-Pacific region and globally.

The Evolution of Tank Destroyers

 Tank destroyers evolved from World War II tactics that relied on high-speed, mobile anti-tank guns. This doctrine has now been replaced by vehicles equipped with anti-tank guided missiles (ATGMs), which combine high mobility with the ability to destroy heavy armor from long distances without direct engagement.

The following is a track record of the evolution of tank destroyers over time:

1. World War II Era: The Birth of Special Doctrines

During World War II, the pressing need to counter massive tank formations gave rise to two main doctrines:

Allied (US) Doctrine: Forming Tank Destroyer Battalions using light, open, and extremely fast tracked vehicles such as the M18 Hellcat. Their tactic was "search, hit, and destroy" using hit-and-run tactics.

M18 hellcat

Axis Doctrine (Germany & Soviet Union): Developed casemate-mounted anti-tank guns, such as the German Jagdpanzer series (e.g., the Nashorn) or the Soviet SU-85, to provide heavy firepower at a lower production cost than standard tanks.

2. Post-World War II: Concept Unification (1945–1960)

Toward the end of the war, the tank destroyer doctrine began to be abandoned. Main Battle Tanks (MBTs) such as the M48 Patton or T-55 evolved with much more powerful cannons and thicker armor. The mobility and firepower of modern tanks ultimately made specialized gun-mounted tank destroyers irrelevant and inefficient for operational purposes for armed forces.

3. Cold War to Modern Era: The Birth of the ATGM (1960s–Present)

To counter the massive armored formations of the Cold War, global militaries introduced the ATGM (Anti-Tank Guided Missile). These specialized vehicles no longer relied on large, heavy cannons, but instead relied on guided missiles.

Advantages: Allows light armored vehicles to disable advanced tanks from very long ranges, often beyond the firing range of enemy tank guns. Modern Examples: Modern vehicles such as the missile-equipped Marder (Germany), the M1134 Stryker ATGM (USA), and modern amphibious vehicles from Russia and China have adopted many fast and easily deployed wheeled platforms.

4. Current and Future Warfare (2020s) 

In contemporary conflicts (including the war in Ukraine), the traditional role of the tank destroyer is evolving again. The threat comes not only from tanks, but also from deadly drones (UAVs).

 In addition to using anti-tank missiles mounted on light armored vehicles, destroyer tactics are now being largely replaced by infantry units using shoulder-mounted missiles (such as the Javelin or NLAW) and kamikaze drone attacks to destroy modern tanks.

The role of the tank destroyer has shifted from being solely a dedicated anti-tank gun to a multi-role platform that integrates long-range missiles to provide precision fire support against enemy armored vehicles.
