In March 2018, Air University Press released a new edition of Colonel John Boyd’s A Discourse on Winning and Losing with a new introduction by Grant Hammond. On top of his heavy influence in designing the F-15 and F-16 fighters, Boyd was one of the most influential and often cited officers in the history of the US Air Force (USAF), but unlike most famous strategic thinkers, he published almost nothing. Thus, this new edition promises to be possibly the most widely disseminated and studied edition of Boyd’s intellectual output.
Boyd is, however, a controversial figure. Among USAF officers, Boyd is either loved or hated. Hammond’s introduction refers to him as ‘legendary,’ ‘a great original thinker,’ and ‘a paragon of virtue – loved by many […] for his character and integrity.’ On the other hand, former fighter pilot and USAF Chief of Staff General Merrill McPeak summarised the opposing view: ‘Boyd is highly overrated […] In many respects he was a failed officer and even a failed human being.’ Boyd was the type of person who challenged authority and fought for what he believed. He was also the kind of person that was so profoundly insecure that he stalked food courts to hunt down and physically assault people whom he perceived had not shown him proper respect. However, many younger officers have never even heard of Boyd nor are they familiar with his ideas or character. With the recent release of the new edition of his work, it is worth taking time to briefly summarise Boyd’s significant contributions and provide some context as to why he is both so praised and so controversial.
First, we must deal with the notion of Boyd as – according to Hammond – ‘a premier fighter pilot.’ Some have referred to Boyd as the greatest fighter pilot who ever lived, and many press outlets mistakenly refer to him as an ace. Although Boyd did fly F-86 Sabres during a brief tour in the Korean War, he does not have a single air-to-air kill to his credit. He never fired his gun in a combat situation. This is not necessarily an indictment of his skills. The reason is that in those years, the USAF tended to fly in formations in which only the lead element was cleared to fire, while the wingmen provided protection. Boyd only ever flew in a wingman position, and never got in an opportunity to fire at enemy MiG-15s. Later, Boyd became a flight instructor at the USAF Fighter Weapons School, and he wrote a manual on dogfighting tactics. His reputation as a fighter pilot was built on his time as an instructor, during which he displayed a penchant for defeating incoming students in simulated dogfights (developing his claim that he could always do so within forty seconds). Fans of Boyd laud him for this, although his detractors often wonder why an instructor defeating his students using an oft-repeated manoeuvre is noteworthy, much less a point worth bragging about.
Boyd’s first significant contribution to USAF thinking was ‘Energy Maneuverability Theory’ (EMT) in the early-to-mid 1960s. This was an application of the principles of thermodynamics to aircraft metrics. Up until that point, the most important metrics for evaluating fighter planes tended to be wing loading ratios, top speed, and acceleration. Many fighter pilots tried to argue that agility and manoeuvrability were more important in a dogfight, but although wing loading could provide a rough idea of how well a craft could turn, it fell far short of an accurate description of a plane’s manoeuvrability. Boyd’s EMT instead analysed how well an aircraft could change energy states – involving speed, acceleration, kinetic and potential energy – essentially giving a numerical value to how well a plane could manoeuvre under various conditions. Charting this value on a graph corresponding to speed and altitude will give a curve of the aircraft’s manoeuvring capability. This method gave fighter pilots a way to talk to engineers in their ‘language,’ and describe dogfighting in mathematical terms, which had a significant influence on aircraft design. Beginning in the late 1960s, EMT became a significant factor in designing and evaluating American aircraft.
Although Boyd appears to have come up with these ideas independently, he was not the first to do so. A decade earlier, in 1954, an aerodynamics engineer working for Douglas named Edward Rutowski had the same concept. Rutowski’s work did not apply to dogfighting, but to calculating fuel ranges of various types of aircraft. However, the equations – and the charts – are almost the same as Boyd’s, who later admitted to copying the charts after denying it for years. One element that Boyd did add, however, was overlaying the EMT curve for one aircraft on top of another, to show where one aircraft had an advantage in manoeuvrability. These comparisons, first done in the late 1960s, showed that Soviet aircraft of that time might have a distinct advantage in dogfighting compared to the American fighters of the day (which, in that period, were mostly interceptors, not traditional fighters). Thus, while not necessarily completely original, Boyd did more to popularise the EMT concept and apply it to fighter design and tactics training, which then became part of a push within the USAF to design aircraft that were more specialised for air-to-air combat.
Boyd had a hand in the design of those planes. The first major USAF project to design a dedicated air superiority fighter was the F-X program, which eventually resulted in the F-15 Eagle. Boyd was brought in partway through this project and attempted to influence the design toward being more dedicated for dogfighting. To Boyd, this meant making it as small as possible and gutting it of sophisticated technologies, especially radar. The more massive the radar dome in a fighter’s nose, the larger the entire plane needed to be. Making the radar as small as possible (or, as Boyd advocated, eliminating it), could make the plane smaller and lighter. Boyd managed to have a significant influence on the design of the F-15, but he did not get everything he wanted. The plane was significantly more extensive and more sophisticated than he advocated, so in disgust, he turned to another project.
Using a combination of subterfuge, connections with high-level decision-makers, stealing unauthorised time on USAF computers, and meeting with aircraft manufacturers in secret using coded language, Boyd pressured the Air Force to procure a smaller lightweight fighter. Boyd wrote the requirements for that plane, which happened to match almost identically the characteristics of a plane he had been secretly designing with General Dynamics’ Chief of Preliminary Design, Harry Hillaker. That plane eventually became the F-16 Fighting Falcon—his ideal true dedicated air-to-air dogfighter. However, Boyd was also disappointed by the modifications made to that aircraft. The USAF made it heavier and more sophisticated than he wanted, and so Boyd denounced it in disgust. Indeed, although his vision for the F-16 was a pure dogfighter, the plane has rarely been used in air superiority missions by the USAF and has achieved zero air-to-air kills for the US.
After his retirement in 1975, Boyd went back to work in the Pentagon as an analyst, and it was during this time that he completed most of the intellectual output in the recently released new volume. This began with a short essay entitled ‘Destruction and Creation,’ which argued that societies and systems only really change when they are destroyed and recreated, rather than reformed from within. In 1976, Boyd received a NASA grant to study the differences in pilot behaviour between simulators and reality. Instead of focusing on that, Boyd produced a study titled ‘Fast Transients Brief,’ which consisted of carefully picked historical examples with which Boyd argued that victory in war was the result of being quick, unpredictable, and agile, with the goal of producing confusing in the enemy. This brief was essentially the first draft of what became a larger briefing called ‘Patterns of Conflict,’ which Boyd continually expanded to include more historical examples of his point. This briefing continued to grow, including more examples, until it became the final form under the new title ‘A Discourse on Winning and Losing.’ In this form, it was a fourteen-hour briefing split into two days. Boyd refused to shorten his briefings or to distribute summaries or slides to those who did not attend, insisting on being given the full amount of time, or nothing.
Also embedded in these briefings was his evolving idea of the OODA loop, which stands for ‘observe, orient, decide, act.’ This was Boyd’s description of the process by which decisions are made at all levels from the tactical to the strategic. Boyd argued that all combatants in a conflict are going through that cycle, and whoever can complete repetitive OODA cycles more quickly will always be the victor. Fans of this theory tend to argue that this insight is revolutionary and secures Boyd’s place alongside thinkers such as Clausewitz or Sun Tzu. Others claim that this idea is very simplistic and offers very little in the way of insight or practical application. Interpreting and applying Boyd’s theory to subjects ranging from warfare to business has become something of a cottage industry. The OODA loop is still taught at US professional military education institutions. Love him, hate him, or merely indifferent, one cannot deny that Boyd has left a legacy and influence.
One final component of Boyd’s life that one must be aware of is his involvement in ‘The Reform Movement.’ During his time in the USAF, he and his followers who pushed for lightweight, dedicated air-to-air combat planes began referring to themselves as the ‘Fighter Mafia,’ and saw themselves at odds with the US government – to the point of depicting themselves as participating in a guerilla war against a government that they deemed as corrupt and ineffective. After Boyd’s retirement, this group morphed into what became known as ‘The Reform Movement’ and moved away from just fighter planes to becoming politically active on broader defence issues. This effort included a litany of journalists, military officers, and politicians who went as far as to form their congressional caucus, as well as non-governmental organisations with the goal of lobbying for particular policies.
The group wanted all US military hardware to be cheap and ‘simple.’ Simple in this context meant technologically unsophisticated relative to the mid-1970s. They argued for cancelling expensive ‘complex’ weapons such as the F-15 and the M-1 Abrams tank and replacing them with cheaper, ‘simple’ alternatives, such as relying on the older M-60 Patton tank or replacing F-15s and F-16s with swarms of F-5 Tigers. ‘The Reform Movement’ was more political than the ‘Fighter Mafia,’ and although the movement attracted some moderates and left-leaning individuals such as James Fallows (journalist for The Atlantic) and Senator Gary Hart (D-CO), it tended to skew conservative. Over time, it grew more conservative with the addition of politicians such as Nancy Kassebaum (R-KS), Newt Gingrich (R-GA), Dick Cheney (R-WY), and possibly its most prominent and active member (who coined the term ‘the Reformers’): self-proclaimed monarchist and white supremacist William Lind. For this group, Boyd was seen as a messiah, and he was often discussed in religious terminology as a saviour preaching a new gospel.
Although this movement had an influential voice in the early 1980s, it had begun to stagnate by the end of that decade, and the 1991 Gulf War discredited many of their arguments. However, despite that war demonstrating the effectiveness of all the weapons systems that the Reformers (and Boyd) had argued against, Boyd himself took sole credit for the success of that war. Boyd claimed he had been the actual author of the ground attack plan, which was not true, and that it would have been even more successful if his ideas had been implemented further.
Boyd is a complex figure, and his influence on the US military, especially the USAF, is impossible to deny. Although the bulk of his work has been floating around the internet for years, having a new edition of his work in an easily accessible and well-produced print edition is extremely useful and quite welcome.
For more information on Boyd, the best place to start is most likely John Andreas Olsen’s 2016 article, ‘Boyd Revisited: A Great Mind with a Touch of Madness’ in Air Power History while the best examination of Boyd’s intellectual output is Frans Osinga’s Science, Strategy and War: The Strategic Theory of John Boyd (2007). Several authors further explore Boyd in Olsen’s edited work Airpower Reborn: The Strategic Concepts of John Warden and John Boyd (2015). A genuinely scholarly biography on Boyd’s life has yet to be written. Hammond’s brief biography, The Mind of War: John Boyd and American Security (2012) is a useful starting point but leans into praise for Boyd to a level that some readers might be uncomfortable with. Robert Coram’s popular biography Boyd: The Fighter Pilot Who Changed the Art of War (2002) has its uses but is little more than hagiography and should be read with a sceptical eye.

 For a brief summary of Lind’s extremism (he was known for keeping a portrait of fascist dictator Benito Mussolini in his office), see Bill Berkowitz, “Cultural Marxism’ Catching On,’ Southern Poverty Law Center, 15 August 15, 2003. Lind’s radical right-wing viewpoints are evident from his voluminous writing as the former Director of the Center for Cultural Conservatism, and his many columns in a variety of conservative websites and magazines. His 2014 novel Victoria not only celebrates a violent militia movement overthrowing the American government but glorifies deportations and executions of non-whites and other minorities he deems undesirable, including Jews, Muslims, the LGBTQ community, and it favorably depicts the use of nuclear weapons against African-American populations.
