Air Warfare Today

My last post summarised the ins and outs of the missile weaponry used by most modern air forces today, and the impact that this had on fighter technology with the development of the interceptor and fighter-bomber as separate classes. This technology was flashy and rose to prominence during the Korean war, but the powers-that-be still used large bomber aircraft during that conflict and were convinced that carpet bombing was the most effective strategy for a large-scale land campaign. And who knows; if WWIII ever ends up happening, maybe that sheer scale of destruction will once again be called for.

However, this tactic was not universally appreciated. As world warfare descended ever more into world politics and scheming, several countries began to adopt the fighter-bomber as their principle strike aircraft. A good example is Israel, long-time allies of the US, who used American fighter-bombers early on during the 1970s Middle East conflict to take out the air bases of their Soviet-backed Arab neighbours, giving them air superiority in the region that proved very valuable in the years to come as that conflict escalated. These fighters were valuable to such countries, who could not afford the cost of a large-scale bombing campaign; faster, precision guided destruction made far better fiscal sense and annoyed the neighbours less when they were parked on their doorstep (unless your government happened to be quite as gung-ho as Israel’s). Throughout the 1960s, this realisation of the value of fighter aircraft lead to further developments in their design; ground-assault weapons, in the form of air-to-surface missiles and laser-guided bombs, began to be standard equipment on board fighter aircraft once their value as principle strike weapons was realised and demand for them to perform as such increased.  Furthermore, as wars were fought and planes were brought down, it was also realised that dogfighting was not in fact a dead art when one’s opponents (ie the Soviet Union and her friends) also had good hardware, so maneouvreability was once again reinstated as a design priority. Both of these advances were greatly aided by the rapid advancements in the electronics of the age, which quickly found their way into avionics; the electronic systems used by aircraft for navigation, monitoring, and (nowadays) help flying the aircraft, among other things.

It was also at this time that aircraft began experimenting with the idea of VTOL: Vertical Take Off and Landing. This was an advantageous property for an aircraft to have since it limited the space it needed for its take off and landing, allowing it to land in a wider range of environments where there wasn’t a convenient long stretch of bare tarmac. It was also particularly useful for aircraft carriers, which had been shown during WW2’s battle of Midway to be incredibly useful military tools, since any space not used for runway could be used to carry more precious aircraft. Many approaches were tried, including some ‘tail-sitting’ aircraft that mounted onto a vertical wall, but the only one to achieve mainstream success was the British Harrier, with two rotatable engine vents that could be aimed downwards for vertical takeoff. These offered the Harrier another trick- it was the only aircraft with a reverse gear. A skilled pilot could, if being tailed by a hostile, face his vents forward so his engines were pushing him in the opposite direction to his direction of travel, causing him to rapidly slow down and for his opponent to suddenly find himself with an enemy behind him eyeing up a shot. This isn’t especially relevant, I just think it’s really cool.

However, the event that was to fundamentally change late 20th century air warfare like no other was the Vietnam war; possibly the USA’s biggest ever military mistake. The war itself was chaotic on almost every level, with soldiers being accused of everything from torture to drug abuse, and by the mid 1960s it had already been going on, on and off, for over a decade years. The American public was rapidly becoming disillusioned with the war in general, as the hippy movement began to lift off, but in August 1964 the USS Maddox allegedly fired at a couple of torpedo boats that were following it through the Gulf of Tonkin. I say allegedly, because there is much speculation as to the identity of the vessels themselves; as then-president Lyndon B. Johnson said, “those sailors out there may have been shooting at flying fish”. In any case, the outcome was the important bit; when (now known to be false) reports came in two days later of a second attack in the area, Congress backed Johnson in the Gulf of Tonkin Resolution, which basically gave the President the power to do what he liked in South-East Asia without making the war official (which would have meant consulting the UN). This resulted in a heavy escalation of the war both on the ground and in the air, but possibly the most significant side-effect was ‘Operation Rolling Thunder’, which authorised a massive-scale bombing campaign to be launched on the Communist North Vietnam. The Air Force Chief of Staff at the time, Curtis LeMay, had been calling for such a saturation bombing campaign for a while by then, and said “we’re going to bomb them back into the Stone Age”.

Operation Rolling Thunder ended up dropping, mainly via B-52 bombers, a million tonnes of bombs across North Vietnam and the Ho Chi Minh trail (used to supply the militant NLF, aka Viet Cong, operating in South Vietnam) across neighbouring Cambodia and Laos, in possibly the worst piece of foreign politics ever attempted by a US government- and that’s saying something. Not only did opinion of the war, both at home and abroad, take a large turn for the worse, but the bombing campaign itself was a failure; the Communist support for the NLF did not come from any physical infrastructure, but from an underground system that could not be targeted by a carpet bombing campaign. As such, NLF support along the Ho Chi Minh continued throughout Rolling Thunder, and after three years the whole business was called off as a very expensive failure. The shortcomings of the purpose-built bomber as a concept had been highlighted in painful detail for all the world to see; but two other aircraft used in Vietnam showed the way forward. The F-111 had variable geometry wings, meaning they could change their shape depending on the speed the aircraft was going. This meant it performed well at a wide variety of airspeeds, both super- and sub-sonic (see my post regarding supersonic flight for the ins and outs of this), and whilst the F-111 never had the performance to utilise them properly (since it was turboprop, rather than purely jet powered) the McDonnell F-4 Phantom did; the Phantom claimed more kills than any other fighter aircraft during Vietnam, and was (almost entirely accidentally) the first multi-role aircraft, operating both as the all-weather interceptor it was designed to be and the strike bomber its long range and large payload capacity allowed it to be.

The key advantage of multi-role aircraft is financial; in an age where the massive wars of the 20th century are slowly fading into the past (ha, ha) and defence budgets are growing ever-slimmer, it makes much more sense to own two or three aircraft that can each do five things very well than 15 that can only do one each to a superlative degree of perfection. This also makes an air force more flexible and able to respond faster; if an aircraft is ready for anything, then it alone is sufficient to cover a whole host of potential situations. Modern day aircraft such as the Eurofighter Typhoon take this a stage further; rather than being able to be set up differently to perform multiple different roles, they try to have a single setup that can perform any role (or, at least, that any ‘specialised’ setup also allows for other scenarios and necessities should the need arise). Whilst the degree of unspecialisation of the hardware does leave multirole aircraft vulnerable to more specialised variations if the concept is taken too far, the advantages of multirole capabilities in a modern air force existing with the modern political landscape are both obvious and pressing. Pursuit and refinement of this capability has been the key challenge facing aircraft designers over the last 20 to 30 years, but there have been two new technologies that have made their way into the field. The first of these is built-in aerodynamic instability (or ‘relaxed stability’), which has been made possible by the invention of ‘fly-by-wire’ controls, by which the joystick controls electronic systems that then tell the various components to move, rather than being mechanically connected to them. Relaxed stability basically means that, left to its own devices, an aircraft will oscillate from side to side or even crash by uncontrollable sideslipping rather than maintain level flight, but makes the aircraft more responsive and maneouvrable. To ensure that the aircraft concerned do not crash all the time, computer systems generally monitor the pitch and yaw of the aircraft and make the tiny corrections necessary to keep the aircraft flying straight. It is an oft-quoted fact that if the 70 computer systems on a Eurofighter Typhoon that do this were to crash, the aircraft would quite literally fall out of the sky.

The other innovation to hit the airframe market in recent years has been the concept of stealth, taking one of two forms. Firstly we consider the general design of modern fighters, carefully designed to minimise their radar cross-section and make them less visible to enemy radar. They also tend to shroud their engine exhausts so they aren’t visually visible from a distance. Then, we consider specialist designs such as the famous American Lockheed Nighthawk, whose strange triangular design covered in angled, black sheets of material are designed to scatter and absorb radar and make them ‘invisible’, especially at night. This design was, incidentally, one of the first to be unflyably unstable when in flight, and required a fly-by-wire control system that was revolutionary for that time.

Perhaps the best example of how far air warfare has come over the last century is to be found in the first Gulf War, during 1991. At night, Nighthawk stealth bombers would cross into Hussein-held territory to drop their bombs, invisible to Hussein’s radar and anti-aircraft systems, but unlike wars of old they didn’t just drop and hope at their targets. Instead, they were able to target bunkers and other such fortified military installations with just one bomb; a bomb that they could aim at and drop straight down a ventilation shaft. Whilst flying at 600 miles an hour.

Fire and Forget

By the end of my last post, we’d got as far as the 1950s in terms of the development of air warfare, an interesting period of transition, particularly for fighter technology. With the development of the jet engine and supersonic flight, the potential of these faster, lighter aircraft was beginning to outstrip that of the slow, lumbering bombers they ostensibly served. Lessons were quickly learned during the chaos of the Korean war, the first of the second half of the twentieth century, during which American & Allied forces fought a back-and-forth swinging conflict against the North Koreans and Chinese. Air power proved a key feature of the conflict; the new American jet fighters took apart the North Korean air force, consisting mainly of old propellor-driven aircraft, as they swept north past the 52nd parallel and toward the Chinese border, but when China joined in they brought with them a fleet of Soviet Mig-15 jet fighters, and suddenly the US and her allies were on the retreat. The American-lead UN campaign did embark on a bombing campaign using B-29 bombers, utterly annihilating vast swathes of North Korea and persuading the high command that carpet bombing was still a legitimate strategy, but it was the fast aerial fighter combat that really stole the show.

One of the key innovations that won the Allies the Battle of Britain during WWII proved during the Korean war to be particularly valuable during the realm of air warfare; radar. British radar technology during the war was designed to utilise massive-scale machinery to detect the approximate positions of incoming German raids, but post-war developments had refined it to use far smaller bits of equipment to identify objects more precisely and over a smaller range. This was then combined with the exponentially advancing electronics technology and the deadly, but so far difficult to use accurately, rocketeering technology developed during the two world wars to create a new weapon; the guided missile, based on the technology used on the German V2. The air-to-air missile (AAM) subsequently proved both more accurate & destructive than the machine guns previously used for air combat, whilst air-to-surface missiles (ASM’s) began to offer fighters the ability to take out ground targets in the same way as bombers, but with far superior speed and efficiency; with the development of the guided missile, fighters began to gain a capability in firepower to match their capability in airspeed and agility.

The earliest missiles were ‘beam riders’, using radar equipment attached to either an aircraft or (more typically) ground-based platform to aim at a target and then simply allowing a small bit of electronics, a rocket motor and some fins on the missile to follow the radar beam. These were somewhat tricky to use, especially as quite a lot of early radar sets had to be aimed manually rather than ‘locking on’ to a target, and the beam tended to fade when used over long range, so as technology improved post-Korea these beam riders were largely abandoned; but during the Korean war itself, these weapons proved deadly, accurate alternatives to machine guns capable of attacking from great range and many angles. Most importantly, the technology showed great potential for improvement; as more sensitive radiation-detecting equipment was developed, IR-seeking missiles (aka heat seekers) were developed, and once they were sensitive enough to detect something cooler than the exhaust gases from a jet engine (requiring all missiles to be fired from behind; tricky in a dogfight) these proved tricky customers to deal with. Later developments of the ‘beam riding’ system detected radiation being reflected from the target and tracked with their own inbuilt radar, which did away with the decreasing accuracy of an expanding beam in a system known as semi-active radar homing, and another modern guidance technique to target radar installations or communications hubs is to simply follow the trail of radiation they emit and explode upon hitting something. Most modern missiles however use fully active radar homing (ARH), whereby they carry their own radar system capable of sending out a beam to find a target, identify and lock onto its position ever-changing position, steering itself to follow the reflected radiation and doing the final, destructive deed entirely of its own accord. The greatest advantage to this is what is known as the ‘fire and forget’ capability, whereby one can fire the missile and start doing something else whilst safe in the knowledge that somebody will be exploding in the near future, with no input required from the aircraft.

As missile technology has advanced, so too have the techniques for fighting back against it; dropping reflective material behind an aircraft can confuse some basic radar systems, whilst dropping flares can distract heat seekers. As an ‘if all else fails’ procedure, heavy material can be dropped behind the aircraft for the missile to hit and blow up. However, only one aircraft has ever managed a totally failsafe method of avoiding missiles; the previously mentioned Lockheed SR-71A Blackbird, the fastest aircraft ever, had as its standard missile avoidance procedure to speed up and simply outrun the things. You may have noticed that I think this plane is insanely cool.

But now to drag us back to the correct time period. With the advancement of military technology and shrinking military budgets, it was realised that one highly capable jet fighter could do the work of many more basic design, and many forsaw the day when all fighter combat would concern beyond-visual-range (BVR) missile warfare. To this end, the interceptor began to evolve as a fighter concept; very fast aircraft (such as the ‘two engines and a seat’ design of the British Lightning) with a high ceiling, large missile inventories and powerful radars, they aimed to intercept (hence the name) long-range bombers travelling at high altitudes. To ensure the lower skies were not left empty, the fighter-bomber also began to develop as a design; this aimed to use the natural speed of fighter aircraft to make hit-and-run attacks on ground targets, whilst keeping a smaller arsenal of missiles to engage other fighters and any interceptors that decided to come after them. Korea had made the top brass decide that dogfights were rapidly becoming a thing of the past, and that future air combat would become a war of sneaky delivery of missiles as much as anything; but it hadn’t yet persuaded them that fighter-bombers could ever replace carpet bombing as an acceptable strategy or focus for air warfare. It would take some years for these two fallacies to be challenged, as I shall explore in next post’s, hopefully final, chapter.

The Hairy Ones

My last post on the subject of music history covered the relatively short timespan between around 1950 and 1965, leaving off at about the time The Beatles began leading the ‘British Invasion’ of American music culture. This invasion was a confluence of a whole host of factors; a fresh generation of youths wishing to identify with something new as ‘theirs’ and different to their parents, a British music scene that had been influenced by the American one without being so ingratiated into it as to snub their ability to innovate and make a good sound, and the fact that said generation of youngsters were the first to grow up around guitar music and thus the first to learn to play them and other genre-defining instruments en masse. Plus, some seriously good musicians in there. However, the British invasion was only the first of a multi-part wave of insane musical experimentation and innovation, flooding the market with new ideas and spawning, in the space of less than a decade, almost every genre to exist today. And for the cause of much of part two, we must backtrack a little to 1955.

Y’see, after the Second World War Japan, the dominant East Asian power, had surrendered unconditionally to the Allies and there was no dominant force in the region. This created something of a power vacuum in the area, with a host of new governments trying to rise from the post-war chaos and establish themselves as such a power. Many of these new nations, including those of China, Cambodia, North Korea and North Vietnam, were Communist states, and therefore were a serious concern to the western world. The US in particular, as a fiercely capitalist power, were deeply worried by the prospect of the whole of South East Asia, according to communist theory, just amalgamating into another great communist superpower and landing them with next to zero chance of triumphing in their ‘battle against communism’ against the already hugely powerful Soviet Union. As such, they were hell-bent on preserving every ounce of capitalist democracy they could in the area, and were prepared to defend such governments with as much force as necessary. In 1950 they had already started a war in Korea to prevent the communist north’s invasion of the democratic south, with the practical upshot (after China joined in) of re establishing the border pretty much exactly where it had been to start with and creating a state of war that, officially, has yet to end. In 1955, a similar situation was developing in Vietnam, and President Dwight D Eisenhower once again sent in the army.

Cut to ten years later, and the war was still going on. Once a crusade against the onward-marching forces of communism, the war had just dragged on and on with its only tangible result being a steady stream of dead and injured servicemen fighting a war many, especially the young who had not grown up with the degree of Commie-hating their parents had, now considered futile and stupid. Also related to ‘the Red Scare’ was the government’s allowing of capitalist corporations to run haywire, vamping up their marketing and the consumer-saturation of America. This might have lead to a 15 year long economic boom, but again many of the younger generation were getting sick of it all. All of this, combined with a natural teenage predisposition to do exactly what their parents don’t want them to, lead to a new, reactionary counter-culture that provided an impetus for a whole wave of musical experimentation; hippies.

The hippie movement (the word is, strangely, derived from ‘hipster’) was centred around pacifism, freedom of love and sex (hence ‘make love not war’), an appreciation of the home made and the natural rather than the plastic and capitalist, and drug use. The movement exists to this day, but it was most prevalent in the late 60s when a craze took the American youth by storm. They protested on a huge variety of issues, ranging from booing returning soldiers and more general anti-war stuff (hippies were also dubbed ‘flower children’ for their practice of giving flowers to police officers at such demonstrations) to demonstrations on the banning of LSD or ‘acid’, one of their more commonly used drugs. This movement of wired, eco-centric vegetarians didn’t connect well with the relatively fresh, clean tones of rock & roll and The Beatles, and inspired new music based around their psychedelic and their ‘appreciation’ of drug use. It was in this vein that The Beatles recorded Lucy in the Sky with Diamonds, and why Jimi Hendrix and Janis Joplin rose to fame in a new genre known as ‘acid rock’ (named after the drug from which most of the lyrics were ‘inspired’). Characterised by long, confusing and hideously difficult solos (I’m looking at you Hendrix), this was the prominent genre on show at the infamous Woodstock festival of 1969, featuring Hendrix, Joplin, The Who, The Grateful Dead & Carlos Santana among other things. Woodstock was the high point of the hippie movement, with over half a million fans attending to smoke, listen to the music, skinny dip and make love in and around the lake and generally by as hippie as possible.

Hippie culture went downhill post-Woodstock; public outcry following the Altamont Free Concert close to San Francisco (where Hell’s Angels provided security and shot a concert-goer during The Rolling Stones’ set for brandishing a gun) coincided with ‘the hippie generation’ mostly growing up. The movement still exists today, and it legacy in terms of public attitudes to sexual freedom, pacifism and general tolerance (hippies were big on civil rights and respect for the LGBT community) is certainly considerable. But their contribution to the musical world is almost as massive; acid rock was a key driving force behind the development of the genres of folk rock (think Noah and the Whale) and heavy metal (who borrowed from Hendrix’s style of heavy guitar playing). Most importantly, music being as big a part as it was of hippie culture definitively established that the practice of everyone, even the lowliest, ‘commonest’ people, buying, listening to, sharing and most importantly making music themselves was here to stay.

The story of hippies covers just one of the music families spawned out of the late 60s. The wave of kids growing up with guitars and the idea that they can make their own music, can be the next big thing, with no preconceived ideas, resulted in a myriad of different styles and genres that form the roots of every style of modern rock music. This period was known as ‘the golden age of rock’ for a reason; before pop was big, before hip-hop, before rap, decades before dubstep, before even punk rock (born in the early seventies and disliked by many serious music nerds for being unimaginative and stupid), rock music ruled and rock music blossomed.

You could argue that this, then, marks the story of rock, and that the rest of the tale is just one long spiral downwards- that once the golden age ended, everything is just a nice depressing story. Well, I certainly don’t like to think of that as true (if only because I would rather not have a mindset to make me stop listening to music),  but even if it was, there is a hell of a lot of stuff left in this story. Over? Not for another post or two…

The Curious Tale of Jack Dunlap

If, gentle reader, you happen to be from the USA, and especially if you happen to live in or in the vicinity of Washington, then you are likely to be more familiar than the rest of us with Arlington National Cemetery. This is a huge graveyard near the centre of Washington DC, and contains a number of war memorials and similar. It also contains the grave of John F Kennedy, whose final resting place it became 4 years after his assassination in 1963 (he had originally been buried in a small plot in the same graveyard, but was later moved to a plot containing a memorial). However, not long before Jack Kennedy was finally lain to rest, another Jack was buried just a little way away- one whose political significance was also huge, but went unknown to almost everyone. His name was Jack Dunlap, and his story is an extraordinary one.

In 1960, Dunlap led an unremarkable life. Married to an unworking wife and with five children, he was a sergeant in the US army with a distinguished record of service in the Korean war and the medals to show for it. However, now he was confined to more mundane work as a clerk-messenger, ferrying important documents around Fort Meade, the National Security Agency (NSA) headquarters in Washington. This made him around $100 a week, which even in 1960 wasn’t much to feed seven hungry mouths.

However, in late 1960 Dunlap encountered a big slice of luck. A distant great-uncle of his died, and bequeathed him a plantation in Louisiana. Suddenly, the dough was rolling in, and Dunlap began living the high life. A new Cadillac, fine suits, smart restaurants, his own cabin cruiser, and his newfound passion for speedboat racing were now within his financial grasp, he told his friends, but he hung onto his job out of a sense that it was important. He didn’t tell most of them about the mistress he had set up in her own apartment, but to her he told a different story. He put on his swagger, and began to brag about how he ‘wasn’t what I say I am’, and all the top-secret stuff his job required him to handle, ending with the old line “If you knew what I actually did, I’d have to kill you”.

Still, the Louisiana story was enough for his NSA bosses, and he received red carpet treatment. Not only was he given days off to go speedboat racing, but after an accident in which he injured his back they sent an ambulance and transferred him to a military hospital. As Jack joked to his friends “They were afraid the sedatives might make me tell a lot of secrets I know”

But to find out the real truth, you’d have to know about a curious fact of his work.  Some of the documents and papers he was entrusted to deliver would turn up late. Very late in fact- nobody noticed, but it might take a day or so for an important paper to get to where it needed to when it passed through Dunlap’s hands. This was because it had taken a little detour- first up Jack’s shirt, then to a man in Washington who would photograph or photocopy them, before being taken back to their intended recipient. The man in Washington was a Soviet agent, and Dunlap was selling his country’s secrets to the USSR.

This was where his newfound wealth had come from- a $50,000 annual salary, around ten times his NSA one, had been offered to Dunlap by the agent in a meeting that autumn ‘to help him bear the expense of his five kids’, in exchange for the information he provided. And provide it he did. Jack Dunlap carried on playing his game of betrayal for nearly four years, on one occasion even bringing an unsuspecting mistress with him to a meeting with his Soviet contact.

However, all good things come to an end, and in Jack Dunlap’s case that end was rather abrupt. In March 1964 his NSA term had come to an end, and he was due to be posted elsewhere- somewhere he might not be able to continue his lucrative trade in information. To try and keep his position (and thus his illicit income), he said that his family were too settled in Washington to move, and asked that, if he could not work for the NSA as a soldier any more, perhaps he could resign and assume work as a civilian.

This would have been a great plan had it not been for one catch- the lie detector. Whilst Army personnel were considered safe, all civilian NSA staff were required to take a session on it before assuming work and, try as he might, Dunlap could not persuade them that his military record excluded him from that. He tried to persuade himself that four years of casual espionage had kept him cool, calm and collected enough to beat the lie detector (which was a fundamentally flawed and eminently cheatable device), but unfortunately it was not to be. Measurements of his muscle movements, breathing, perspiration and heart rate when answering rather sensitive questions altered the NSA opinion of him from a trustworthy, honest, efficient worker to a habitual sneak ‘capable of petty theft’. Whilst not a damning indictment of the high treason he was performing, it was enough to get Dunlap transferred to a desk job and to get his bosses asking around. The plantation in Louisiana was found to be bogus, and they started trying to find out where Dunlap’s wealth came from.

For Dunlap, this was a terrifying time. Without any secrets to ferry and sell, he was abandoned by his Soviet contact. He knew perfectly well that four years of betraying such sensitive information was more than enough to send him to the electric chair, or at least the rest of his life in maximum security without a hope of parole. His mental state began to unravel- he had paranoid fears of shadowy men in dark corridors asking him to ‘just come this way’, or a platoon of soldiers kicking down the door. Finally, it all got too much for him, and on July 22nd, 1964, he drove to an abandoned creek and suffocated himself with his car’s exhaust fumes.

During his time as a spy, Jack Dunlap ‘told’ the Soviet Union almost everything about the United States’ coding machines, revealed exactly what the US knew about Soviet military power, and handled some information concerning Oleg Penkovsky a Soviet double agent working predominately for the British that went straight back to the Soviets and almost certainly helped lead to the eventual capture and execution of one of the most influential intelligence tools the western powers had (Penkovsky was a Soviet colonel who, disillusioned with his country’s politics, had begun to play exactly the same treacherous game as Dunlap). And that’s only the stuff we know about- the KGB have (understandably) never released the information they got from Dunlap, so he could even have contributed to Kennedy’s assassination for all we know (far be it from me to add yet another string to that particular conspiracy theory). Many might consider him a traitor, a villain who gave up both his principles and his country for a couple of hundred thousand bucks- but then again, we might consider Penkovsky, playing the same game, a hero who died in the fight against communism. What we can all be sure of, however, is that Jack Dunlap almost certainly changed the course of history in his own little way- much like the other famous Jack spending his eternal slumber just a stone’s throw away.
