**Breaking News: The Persistence of the Old Guard — 10 Anti-Aircraft Guns Still Defending Our Skies**

In an era dominated by advanced missile technology and sophisticated air defense systems, the resilience of vintage anti-aircraft guns is a startling revelation. Despite their age, these relics of warfare continue to play a vital role in global air defense, protecting nations from aerial threats. As military forces adapt to modern challenges, these ten oldest anti-aircraft guns remain steadfastly operational, showcasing a blend of reliability and cost-effectiveness that newer systems often lack.

Kicking off our list is the ZU-23-2, a Soviet twin 23 mm towed anti-aircraft gun that first entered service in 1960. With an astonishing production figure of around 140,000 units, it has become a staple in regions like the Middle East, Africa, and Asia. Its lightweight design and versatility allow it to be mounted on trucks, making it an agile defender against low-flying aircraft, including helicopters and drones.

Following closely is the ZSU-23-4 Shilka, another Soviet innovation from 1960. This self-propelled gun boasts four 23 mm autocannons and a radar-guided system, delivering a staggering rate of fire that can reach up to 2,000 rounds per minute. Its modernized versions are still deployed by nations such as India and Syria, proving its worth in today’s combat scenarios.

The ZSU-57-2, introduced in 1957, is yet another testament to the durability of these weapons. With its dual 57 mm autocannons, it has seen action in numerous conflicts, including Vietnam. Presently, it is still operational in North Korea and various African armies, highlighting its continued relevance.

Next, we have the AZP S-60, a 57 mm towed automatic anti-aircraft gun that has served since 1950. It remains in use in several countries, including Vietnam and Syria, frequently adapted for roles beyond air defense, as seen in the ongoing conflict in Ukraine.

The ZPU family of anti-aircraft guns, particularly the ZPU-4, has been a widespread light defense weapon since 1949. With over 100,000 units produced, it remains a common sight in conflicts across Africa and the Middle East.

The KS-19, a heavy 100 mm anti-aircraft gun from 1948, continues to be a formidable presence in static and reserve roles, particularly in North Korea. Its ability to engage high-altitude targets makes it a critical asset for ground forces.

The M1939 37 mm gun, which saw extensive action during World War II, is still operational in various regions, including North Korea and Syria. Its legacy as a reliable anti-aircraft weapon endures, even as it adapts to secondary roles.

The Orlic 20 mm cannon, designed in Switzerland and entering service in 1937, remains a staple for both ground and naval forces. Its versatility ensures it continues to serve in various capacities across the globe.

The QF 3.7 inch anti-aircraft gun, a British design from 1937, is still found in some Commonwealth countries, albeit in ceremonial roles. Its historical significance during the Battle of Britain cements its place in military heritage.

Finally, the Bofors 40 mm L60, introduced in 1934, is one of the most widely used anti-aircraft guns in history. Though many countries have transitioned to modern systems, it remains operational in nations like Norway and Brazil, showcasing its enduring effectiveness.

As these aging artillery pieces continue to defend the skies, their presence serves as a reminder of the past’s influence on modern warfare. In a world where technological advancements dominate, the steadfastness of these anti-aircraft guns proves that sometimes, the old guard has a crucial role to play in the defense of nations.
