War from a Technological Perspective

Introduction

Warfare as an advancement of technological progress has always been an arms race. At all stages of history, the motivations for conflict remained the same: conquest and resources, geopolitical dominance, survival. However, the way wars were fought changed depending on the state of technology. Any given technological innovation could produce military organizational consequences, shifts in tactical doctrines, and even changes in the balance of power between countries. Technology has made armies more lethal and better protected but has also made wars more devastating and caused new changes in the ways humans live (Keegan).

Part I: Ancient & Medieval Warfare (Prehistory – 1500)

The dawn of humanity saw the appearance of the first primitive weapons, which were made of stone, bone, and wood. The development of the first city-states during the Neolithic period produced the first organized forms of military government and allowed societies to specialize in weapons manufacturing. The dawn of metallurgy in approximately 3300 BC led to the bronze age military revolution. Egyptian, Mesopotamian, and other early civilizations produced better-edged weapons and body armor, which allowed their soldiers to gain significant advantages on the battlefield. Another technological development that saw military applications was the invention of the war chariot, which further utilized animal traction for increased mobility and allowed ancient warriors to fight at a distance (Keegan).

A significant development in approximately 1200 BC led to the Iron Age. Unlike bronze, iron was much more available, which led to the production of weapons and armor affordable to most nations. Assyrian empire builders developed large armed forces consisting of professional soldiers who used iron weapons. Siegecraft also saw wide use, as the Assyrians pioneered technologies and methods allowing to surround and capture walled cities. Later, the Classical period saw the development of new military tactics, as the Ancient Greeks introduced heavy infantry, better equipped and trained than their opponents. The hoplon, a large shield carried by Greek warriors, allowed them to form tight formations called phalanxes, which were extremely hard to break (Keegan).

The Romans perfected the Greek military model, introducing better standards of equipment and training. Roman generals understood the importance of mobility and infrastructure, which led to the construction of many roads and bridges. After the fall of the Roman empire, European feudal systems favored heavy cavalry and static defense. New developments in steel production led to the production of closed armor for knightly infantry. This development triggered a technological arms race, as siege weapons and artillery saw widespread use. The mechanical crossbow and the English longbow became very popular in the European warfare of the medieval period (Contamine).

Gunpowder use and the subsequent innovation arms race rendered most of the existing fortifications and siege weapons ineffective. The technological development that took gunpowder from Chinese inventors saw limited early use but soon led to the creation of many firearms and cannons. Although early cannons and firearms were rather inaccurate, their explosive power easily damaged the previously dominant stone castles. Overall, the introduction of gunpowder rendered previous forms of army protection useless and marked the end of the medieval period (Needham; Parker).

Part II: Industrial Warfare & Mechanization (1500 – 1945)

The early modern period saw the transition from cold steel and bows and arrows to firearms. Matchlock and flintlock mechanisms allowed ordinary infantry soldiers to fight in large formations without years of training. Large earthworks acquired the shape of low-profile star-shaped bastions that resisted cannon fire. On the seas, the development of cannons and their introduction to warships allowed European states to build their colonial empires (Parker).

The industrial revolution saw a technological explosion, which affected all aspects of military machinery. Industrialization replaced many traditional aspects of warfare, such as blacksmithing, as new machines produced large quantities of standardized parts. Steam, electricity, and telegraphy allowed militaries to expand and better control their operations. The American Civil War saw the introduction of many modern technologies, such as large railroads, telegraph wires, and rifles. Rifling allowed muskets to have better accuracy and range, and they soon replaced various smoothbore firearms. The development of ironclad warships soon rendered traditional wooden ships ineffective (Keegan).

The First World War was a manifestation of total industrial warfare. The large-scale production of firearms, particularly various machine guns, and large-caliber field artillery, created a new deadly obstacle for attacking soldiers. Barbed wire and poison gas further improved the defensive capabilities of well-prepared positions, leading to the advent of trench warfare. The inability of infantry and even traditional cannons to effectively attack such strongly held positions led to two technological innovations: military aircraft and armored vehicles. 

Airplanes developed from simple observation devices into long-range bombers, and fighter planes appeared, allowing air superiority to become an integral aspect of modern warfare. Likewise, armored vehicles introduced mobility and firepower into the equation, becoming a countermeasure to static defenses. WWI also saw the development of various communication devices and radar technology, which improved the effectiveness of artillery and anti-aircraft defenses (Keegan).

The Second World War produced many technological advances, which further improved the capabilities of airplanes, armored vehicles, and ships. Modern armored tanks saw combat for the first time, and their further development allowed them to resist enemy fire while being able to inflict heavy damage. However, the dominance of big ships and capital armored ships was quickly overtaken by aircraft carriers. Various aspects of radio-electronic warfare also developed, as technologies allowed for better utilization of electronics. The technological development also led to the creation and use of nuclear weapons, whose power had not been seen before in the history of the world (Keegan).

Part III: Modern Warfare And Space Age (1945 – Present)

The Cold War technological arms race produced many new innovations, primarily centered around the development of ballistic rockets and nuclear warheads. Nuclear technology changed the nature of warfare, as the possibility of launching a nuclear attack made most military actions irrational due to the possibility of a retaliatory strike. The entire military doctrine of the new era revolves around one idea: Mutual Assured Destruction. New developments in aerospace technology allowed for the utilization of low-Earth orbit and deep space, as satellites became a critical element of modern military infrastructure. Various applications were implemented, ranging from simple monitoring of potential enemy missile launches to improved global navigation and secure communications (Freedman).

The modern age has seen the transition from purely kinetic warfare to information warfare. Modern military technology allows for the use of precision-guided missiles and bombs, which minimizes collateral damage by hitting only selected targets. The use of stealth technology allows for aircraft to avoid being targeted despite their size and speed. Moreover, the global adoption of the internet has created a new domain of warfare: cyberspace. Modern military forces use computer technology to conduct surveillance, sabotage, and even economic warfare against adversaries. The development of new technologies continues, with various applications such as drones allowing for the minimization of friendly casualties by taking over some of the duties of humans (Singer).

The future of military technology lies in further automation and miniaturization. Researchers are currently developing new high-speed missiles that can travel at speeds above Mach 5 while maneuvering to avoid enemy fire. Another area of development centers around lasers and other directed-energy weapons, which utilize the speed of light to destroy aircraft and other spacecraft. The future of war will be increasingly dominated by artificial intelligence and robotic systems, allowing for faster processing of information and making decisions in real-time. The increasing reliance on space and unmanned systems will require improvements in related technologies, such as orbital mechanics and algorithms. However, as human actions are increasingly automated, humanity may find itself in the situation of having to control overly powerful systems that can be dangerous if not regulated (Singer; SIPRI).
