Top 10 innovations that have revolutionized the military

The 21st century has witnessed a flurry of military innovations, blurring the lines between science fiction and reality. From human-like robots to self-driving vehicles; smart phones to top-of-the-line computers the 21st century has witnessed technology evolution at speeds never experienced before.  

One of the principal drivers behind this change — is the military. Experts say the new decade will see many more advances in unmanned vehicles, artificial intelligence, aircraft, maritime vessels, land vehicles, cyber security, medical technologies, and such areas.

Choosing the “top 10” is not easy considering the fact that each advancement impacts different aspects of warfare. However, here are 10 major innovations that have significantly reshaped the military landscape:

An unmanned aerial vehicle (UAV) is an aircraft that carries no human pilot or passengers. UAVs—sometimes called drones—can be fully or partially autonomous but are more often controlled remotely by a human pilot. Drones have become a staple in modern military operations, providing surveillance, reconnaissance, and even offensive capabilities without putting human pilots at risk. The history of UAVs dates back to 1783 when Joseph-Michel and Jacques-Étienne Montgolfier demonstrated the first unmanned hot-air balloon in France. In 1849 the UAVs were used for the first time in warfare when Austrian artillery lieutenant Franz von Uchatius invented the balloon bomb and Field Marshall von Radetsky used them to attack Venice. In 1896 – Alfred Nobel, placed the first Camera on a UAV. Finally in 1935 De Havilland DH.82B Queen Bee aircraft used a low-cost radio-controlled drone for aerial target practice. It is considered by many to be the first modern drone. The Battle of Jezzine in 1982 was the first battle where drones made a considerable difference. In this war Israel employed drones to outmaneuver the Syrian Air force and win the battle with minimal casualties.  The Vietnam War in 1985 once again made it clear that drones would have a growing role on the battlefields of the future. The Gulf War in 1991 was the first major conflict in which at least one drone was airborne from the start to finish.

In mid-2000– UAVs were for the first time permitted in US civilian airspace for search & rescue and disaster relief operations following the devastation caused by Hurricane Katrina. To make this happen predator drones with thermal cameras were used to detect the heat signatures of humans from up to 10,000 feet away. This marked the beginning of the consumer drone industry.

Cyberwarfare has emerged as a critical aspect of military strategy in the 21st century. Cyberwarfare is a complex and ever-evolving domain. Understanding the technologies involved is crucial for both nations and individuals to prepare for and mitigate the risks associated with cyberattacks. As the digital landscape continues to evolve, responsible development and international cooperation are essential to ensure a secure and stable cyberspace for all.

While these technologies offer immense potential for both good and bad, their responsible development and ethical use is crucial. Already many nations are investing heavily in offensive and defensive capabilities to gain an edge in the digital battlefield. Here’s a glimpse into some of the key technologies shaping cyberwarfare:

Precision-guided munitions (PGMs) include missiles and bombs designed to precisely hit specific targets, thus minimizing collateral damage and increasing overall military effectiveness. These munitions use guidance systems to navigate and direct themselves towards their intended targets with a high degree of accuracy. The primary advantage of PGMs is their ability to strike specific target with minimal risk of damage to surrounding areas. The improved accuracy also results in fewer munitions being required to achieve the same objectives compared to traditional unguided weapons.

Precision-guided munitions may include:

  • Guided Bombs (GBU): These are traditional bombs fitted with guidance systems. The guidance can be GPS-based, inertial navigation systems, or laser-guided. GPS-guided bombs use satellite navigation to reach their target, while laser-guided bombs rely on a laser designator to mark the target.
  • Cruise Missiles: Cruise missiles are self-propelled guided missiles with an ability to fly for an extended period, sometimes at low altitudes. They use various guidance systems, including inertial navigation, GPS, terrain contour matching, or a combination of these, to reach their targets with precision.
  • Precision Artillery Munitions: These include guided projectiles for artillery systems. They use guidance systems like GPS or inertial navigation to accurately hit targets at a distance.
  • Anti-Ship Missiles: These are precision-guided munitions designed specifically to target naval vessels. They can use various guidance systems, such as radar, inertial navigation, or GPS, to home in on their targets.
  • Precision-guided Rockets: Similar to artillery munitions, these are rockets equipped with guidance systems to improve accuracy.
  • Unmanned Aerial Vehicle (UAV) Weapons: Drones equipped with precision-guided munitions can accurately target and strike enemy positions.

Stealth technology, also known as low observable technology involves techniques designed to make an aircraft, spacecraft, or other object difficult to detect by radar, infrared, sonar, and other detection methods. The primary goal of stealth technology is to reduce the signature of objects, making them less visible or identifiable by enemy sensors enhancing their ability to conduct covert operations. Stealth technology is primarily associated with military applications, including aircraft, naval vessels and submarines like the F-117 Nighthawk and B-2 Spirit. Developing effective stealth capabilities involves a combination of advanced engineering, materials science, and a deep understanding of various detection methods.

It’s a type of projectile launcher that uses electromagnetic forces to accelerate a projectile along a set of rails. It is a linear motor device that consists of two parallel conductors (rails) along which a sliding armature is accelerated by the electromagnetic effects of a current that flows down one rail, into the armature, and then back along the other rail. Railguns can achieve much higher velocities than conventional guns, which are limited by the explosive power of gunpowder. Railguns have been tested to speeds of over 11,000 km/h, which is more than Mach 9.

One of the main advantages of railguns is that they do not require any explosives or propellant to launch their projectiles. This makes them safer to store and transport, and it also reduces the risk of accidental detonation. However, railguns also have some disadvantages. They require a large amount of electrical power to operate, and they can be very expensive to build and maintain. Additionally, the high speeds of railgun projectiles can create a lot of wear and tear on the rails, which can limit the lifespan of the weapon.

Despite these challenges, railguns are still a promising technology with the potential to revolutionize warfare. They are being developed by militaries around the world, and it is likely that we will see them deployed in combat in the future.

Innovations in materials science have led to the development of lighter yet stronger armor, providing better protection for military vehicles and personnel.

4. Metamaterials:

  • These engineered materials with artificially tailored properties are being explored for their ability to manipulate electromagnetic waves and even light. Metamaterial-based armor could potentially deflect projectiles or even render them invisible to radar.

5. Self-healing materials:

  • Researchers are developing materials that can autonomously repair damage, which could revolutionize armor technology. Imagine armor that automatically heals cracks or even re-knits bullet holes!

Network-Centric Warfare (NCW) is a military doctrine or approach to warfare that emphasizes the use of information networks to connect sensors, decision-makers, and weapons systems to achieve a decisive advantage on the battlefield. NCW is still evolving, and new technologies are emerging all the time. As these technologies become more mature, we can expect to see even greater integration and automation on the battlefield. Some of the benefits of NCW include increased speed and agility. NCW allows forces to react quickly to enemy movements and seize opportunities. Improved situational awareness – NCW gives commanders a clear picture of the battlefield, leading to better decision-making. Enhanced lethality- NCW allows for more precise targeting and coordinated attacks, leading to greater effectiveness against enemy forces. Reduced collateral damage- NCW’s focus on precision targeting minimizes civilian casualties.

Examples of NCW in action:

  • Operation Iraqi Freedom: The US military used NCW to great effect during the invasion of Iraq in 2003. By sharing real-time intelligence and coordinating attacks, US forces were able to quickly overcome Iraqi defenses.
  • Operation Enduring Freedom: NCW continues to play a role in the ongoing war in Afghanistan. The use of drones and other networked sensors has helped to track down Taliban and Al-Qaeda fighters.

Biometrics, such as fingerprint and facial recognition, are increasingly used for secure access control and identity verification in military applications. These technologies leverage unique physical or behavioral characteristics to identify and authenticate individuals, offering enhanced security, efficiency, and operational effectiveness.
