North American F-86 Sabre

This entry is part 18 of 18 in the series Beautiful Destroyers

The F-86 ‘Sabre’ is certainly one of the most beautiful aeroplanes from the Cold War era, and is an icon of the classic jets genre.

First used in combat in the Korean War, the Sabre soon proved itself to be the best of the fighter aircraft in the United Nations’ arsenal, and it was the only fighter capable of facing the North Koreans’ MiG-15 fighters on equal terms. Other fighters fielded by the UN were either slower piston-engined prop jobs like the F-51 Mustang, or straight-wing jets such as the Lockheed F-80 Shooting Star and the Gloster Meteor, which were a good deal slower than the MiG-15.

But the Sabre was fast (it was just supersonic in a shallow dive), manoeuvrable, had good visibility from its bubble canopy, and was often flown by experienced combat veterans who had fought in WWII. In many ways, the Sabre and MiG-15 were virtually equal aircraft, each with strengths and weaknesses with respect to the other, very much like the Spitfire and the Messerschmitt 109 were in the Second World War. Here are a preserved Sabre and MiG-15 seen together at an airshow in the USA (photo is clickable to magnify):

But the Sabre is just plain beautiful, and that’s one reason why I’m featuring it in ‘Beautiful Destroyers‘.  Look at those lovely clean lines, the perfect wing sweep angle, the sleekness of the curves of the fuselage…this is a beautiful aeroplane in the same league in the beauty stakes as the Hawker Hunter.

In the photo above, you can clearly see the ‘bubble’ shape of the canopy; this gave the pilot an excellent all-round field of view; this is very advantageous in close-in air combat. There is an old fighter-pilots’ adage: ‘He who sees, wins’ and the Sabre’s canopy certainly fits the bill for that purpose.

Armed with six 0.50″ machine guns, the Sabre packed quite a punch – the six 0.50-cal machine guns were a proven weapons fit from the Second World War – but they did not have quite the range of the cannon with which the Soviet fighters like the MiG-15, and jet bombers like the Ilyushin-28, were armed.

Indeed the early Sabres were in some ways some of the last of the gun-only armed aircraft; changes in the performance of jet bombers meant that there had to be new developments in air-to-air combat that would enable fighters to bring down Soviet bombers which had nearly as good speed and altitude performance as the fighters that would be trying to stop them in the event of a war.

Eventually, the ability to stop fast jet bombers was realised by the advent of air-to-air guided missiles; indeed the Sabre was one of the first aircraft to be fitted with early versions of the AIM-9 ‘Sidewinder’ heat-seeking missile. But in the meantime, other methods had to be developed to enable interceptors to attack enemy bombers without being exposed to withering cannon fire from the tail turrets of aeroplanes such as the Tu-95 ‘Bear’. (Remember that at this time in history, the ‘Cold War’, the threat of nuclear war was ever-present, and the West and the East both poured tons of money into developing effective defences against enemy nuclear-armed bombers). The temporary stop-gap measure adopted by the USA and Canada, at least, was to arm their interceptor jets with many unguided ‘folding-fin aerial rockets’ (FFARs) which had explosive warheads but which had to actually hit their targets directly in order to cause damage. A good number of these rockets were carried by various interceptors, from 24 in the F-86D (below) and F-102A, to a massive 108 FFARs in the Northrop F-89D ‘Scorpion’. The idea was to attack enemy bombers using a single head-on pass, using a specialist radar-guided attack computer which launched all the FFARs at the target in one (hopefully devastating) salvo. Hopefully, the combination of reasonably accurate aiming and the ‘shotgun’ effect of having so many FFARs in the air at the same time, would bring down the enemy bomber before it got to its target. That’s what interceptors are supposed to do.

And so was born the F-86D ‘Sabre Dog’; the FFAR-armed interceptor version of the F-86. The inclusion of the fire control radar and the retractable rocket tray meant that the airframe shape was nowhere near as graceful as the gun-armed F-86s, but I suppose it was for a reason and it did its job. The F-86D was never intended for fighting against enemy fighters, though; its entire armament for its mission was based around the single salvo of FFARs, to be used to intercept a single enemy bomber. You only got the one shot. Here is the F-86D, and another shot showing its retractable rocket tray, which was just under the cockpit:

The big black dome on the nose of the Sabre Dog (which I feel spoils its lines!) is the radome containing the fire control radar for the FFAR aiming computer. Here’s another shot of the whole FFAR salvo going off:

Impressive though that looks, this technique is of questionable value at best; it was appallingly inaccurate, and it was fortunately never really necessary to use it for real, in this role at least. (See the Wikipedia article on FFARs for more on this)

Now, this is more like it. Here is a gorgeous painting of an F-86 punching off its drop-tanks as it prepares to engage a North Korean MiG-15:

Drop tanks were an idea from the Second World War, where fighters could extend their range by carrying extra fuel in external tanks. Because these external tanks increased the weight and drag of the aeroplane, they could be dropped, or ‘punched off’, as the enemy was sighted, hence the name ‘drop tanks’.

The fighter would then be lighter and cleaner and better able to engage the enemy. The idea was that you would use the fuel from the drop tanks first, so that the tanks would hopefully be empty by the time you ran into trouble and jettisoned them. Or, if you didn’t make contact with enemy aircraft, you could just bring the tanks home empty and use them again.

The Sabre served with many nations’ air forces , including the Royal Air Force, for many years and in many operational theatres, with the last ones being retired from service in the Bolivian Air Force in 1994.

So, there she is; the F-86 Sabre. Beautiful lines, sleek, fast and deadly. A ‘Beautiful Destroyer’ for sure.

Boeing B-17 ‘Fortress’

This entry is part 15 of 18 in the series Beautiful Destroyers

….and the 8th Air Force Legacy

Today’s Beautiful Destroyers post is just a little bit different, because not only do I showcase the legendary Boeing B-17 ‘Flying Fortress’, but I also present a little game you might like to try.b-17e

The B-17 ‘Fortress’ was the mainstay (along with the B-24 ‘Liberator’) of the United States 8th Air Force, flying from bases in the UK during World War II. This aeroplane has long been one of my favourite American aircraft from WWII.

Here’s the mighty B-17G Fortress ‘Sally-B’, one of the (happily) many airworthy examples flying today. She’s dressed up as the legendary B-17F* ‘Memphis Belle’, which was the first Fortress to complete the required 25 missions to enable her crew to return home to the United States.

sally-b

The doctrine which inspired the design and construction of the B-17 was that ‘The Bomber Will Always Get Through’; an inter-war concept whereby bombers would be designed that were so fast and high-flying that fighters (which when the doctrine was formulated, had similar performance to the bombers) would not be able to intercept them. However, by the time the early B-17’s were designed, they knew that the fighters would most likely be able to catch the bombers. And so the Fortress was designed, basically with guns providing all-around firepower protection; defences covering every possible approach angle so that enemy fighters would have to run the gauntlet of heavy defensive fire no matter where they attacked from – hence the nickname ‘Flying Fortress’. And so, with the benefit of this all-round armament, the Fortress was supposed to have been able to make it all the way to the target (The bomber will always get through!), without fighter escort, and defend itself (and its squadron mates, with which it flew in a defensive ‘box’ formation to maximise mutual supporting firepower) all the way to the target and back.

Of course, however, as with all such combat doctrines, the reality did not match up with the theory. Although at first, the B-17s could indeed get through to the target without serious losses, and deliver their bombs reasonably accurately, this did not last long. On the first daylight bombing mission, on 17th August, 1942, only two bombers suffered minor damage. However, the German fighter leaders of course developed tactics which they used successfully against the Fortress formations. This is what professional soldiers do well; if there is a tactic that works (in this case, massed formations of machine-gun toting bombers), you develop a counter-tactic, and so on. One of the primary such tactics was to attack the bomber formations head-on, where a) the bombers had weaker defensive weaponry (at some angles, just a single machine gun), and b) the closing speed was so high (of the order of 600mph) that accurate fire was difficult. But still the Fortresses had to go in in daylight – the whole idea was that they could actually see the target they were dropping their bombs on, unlike the RAF night raids where the bombers relied on a combination of good navigation and luck in order to hit their targets – if indeed they did hit their targets.

And so they found that the Fortress benefited from a fighter escort almost as well as did the Germans in the Battle of Britain. Both sides had learned that unescorted bombers iin daylight are vulnerable – but still the B-17 was far more capable of defending itself than were the much more lightly-armed German Heinkels and Dorniers they used in the Battle of Britain. In fact it wasn’t until early 1944 that the Fortress got a fighter escort all the way to the target; on the notorious raids on Schweinfurt and Regensburg in August 1943, the Fortresses lost nearly ten percent of their strike force, being escorted only about 25% of the way there and for the last 25% of the flight back. In October 1943, the second Schweinfurt mission resulted in such catastrophic losses (about 20%) that these missions in fact foretold the failure of the concept of deep-penetration unescorted daylight raids over Germany, in spite of the Fortress’s heavy defensive armament, and while raids continued unabated for the rest of the War, unescorted deep-penetration raids did not. Not until late 1943 were long-range escort fighters sufficiently long-legged to make it all the way to targets deep in Germany and back.

In fact, eventually, the US long-range escort fighters performed so well that some B-17 crews flew two 25-mission tours without ever seeing an enemy fighter.

The Fortress was held in high regard by its crews, because even though the bombers were regularly clobbered good and proper by both enemy fighters and flak (anti-aircraft fire), they had a reputation for being unbelievably tough.

“There were occasions where, any other airplane, took hits the way it took….wouldn’t’a brought us back…”

“God love ’em. They’d bring you home when you didn’t think you had a prayer, and, … they’d never let you down….”

“When you see what the B-17 went through, in combat, and still make it back home … it was a miracle to me”

Some Forts were indeed able to make it back home with some of the most incredible battle damage; damage that would easily have felled any other combat aircraft in the War. Some examples are given here. This Fortress, for example, was damaged in a collision with a German fighter which tracked its wingtip down across the rear fuselage and took off the left tailplane (horizontal stabiliser) too.

Or this Fort, where a Flak shell had exploded directly in front of the nose of the aircraft:

…and they incredibly managed to fly that aeroplane home! This, while extreme, is typical of the kinds of damage these areoplanes used to absorb and still survive.

In this picture, you can see the contrails (the white vapour trails) of escorting Allied fighters above the B-17 formation:

Here’s a lovely picture of a B-17G on its bomb run. Note the spiral contrails induced by the spiral propeller wash.

And another incredibly atmospheric shot, this time a backlit picture of the propeller tips forming their own slipstream vortices:

And another beautiful picture of a B-17 formation and its contrails – beautiful but deadly. These contrails made it impossible for the defending German fighters to not see the American formations approaching.

So, the B-17 Fortress – another Beautiful Destroyer. Loved by its crews, but suffering heavy losses until the advent of 100% fighter escort.


And now for the little game, which I appreciate will only be of interest to WWII geeks 😉 I call this little exercise the ‘8th Air Force Legacy’.

During World War II, several tens of airbases were constructed during 1942-1943, in East Anglia – roughly the area east of Cambridge/Peterborough – in the United Kingdom. These bases were to be home to the tens of thousands of American servicemen whose mission it was to launch daylight air raids into Occupied Europe in order to cripple Nazi Germany’s war machine industry.

Whereas the RAF conducted its bombing campaign at night – largely a fairly indiscriminate ‘terror campaign’ waged against Germany’s civilian population (although many raids were also sent against German industrial targets in areas like the Ruhr Valley) – the US Army Air Force doctrine called for daylight precision bombing – attacks so accurate that the targets would be hit and hit hard.

The bases were placed in East Anglia so that they would be at the nearest practical ‘jumping-off point’ for raids into Europe. Raids began in August 1942 when twelve B-17s of the 97th Bombardment Group attacked the railway marshalling yards at Rouen. Within months, it became common for the skies above East Anglia to be filled with the reverberating snarl of aircraft engines as hundreds of bombers assembled their formations before commencing their long, freezing flights out over Nazi Germany and back again. Visions of the ground crews waiting anxiously for the first sound of approaching B-17s, returning from storms of flak and rivers of bullets. The culmination of the campaign against the Nazi war machine was in August 1943, where two raids were conducted against the ball-bearing plants at Schweinfurt, and the Messerschmitt factory at Regensburg, both deep in Germany, as already mentioned.

These air bases were absolute hives of activity. Thousands of personnel, hundreds of aircraft, thousands of vehicles, tons of ammunition, bombs, fuel, spare parts; busy hangars and repair shops, briefing and canteen facilities, chapels, stores, barracks – each airfield was a small town and was more-or-less self contained.

Many of these bases were closed at the end of the War, some were kept going, but now, over seventy years after the end of the War, there is in some cases little left of these once bustling places. Like navvy shanty-towns, they served their purpose, and were then left to fall into decay. Places full of memory, full of history, are now once again reverted to being farmers’ fields or other uses. Polebrook, Kimbolton, Snetterton Heath, Bassingbourn, Thorpe Abbots. Names that evoke visions of B-17s running up their engines, long grass waving behind in the prop wash, the thunder of engines as the heavily-laden B-17s rumble down the runways and lurch into the air, men playing baseball until the returning bombers could be heard, red flares on final approach to signify that the bomber had wounded aboard, wheels-up landings on one engine….

Now, here’s the game. Use Google Maps/Google Earth (satellite view) to search for the place names given below, and see if you can see the bases, or what’s left of them, nearby. Or even just if you can see where they were. As an aid, you can type in the names of the bases into Wikipedia, and get an idea of what the shapes of the airfields were like. In Wikipedia, add RAF in front  – RAF Polebrook, for example. Clue: Most of the airfields had three intersecting runways arranged in a rough overlapping triangle pattern. And take a look at what some of them are used for now – Snetterton Heath is a good example. Also, where possible, try the Google Street View on them – at Rattlesden you can even look along one of the runways that used to be used for B-17s (it’s now a gliding airfield). Would you believe that a very few of these are still active airfields in one form or another!

Here are the names you’re looking for:

Alconbury (an easy one to begin with)
Snetterton Heath
Rattlesden
Knettishall
Bassingbourn
Polebrook
Thorpe Abbotts
Framlingham
Grafton Underwood
Molesworth
Deenethorpe
Glatton
Podington (I think this is a drag-racing track!)
Chelveston (a very hard one!)
Thurleigh
Kimbolton
Ridgewell
Nuthampstead

Each of these bases was near(ish) to the village from which it took its name. Thorpe Abbotts is a bit further away, but that’s part of the fun. Look at the Google Maps from different heights and try to to spot the patterns in the ground. Polebrook is a particularly difficult one, as are Knettishall and Kimbolton. Give it a go and see how you get on. And, as always, comments are welcome 🙂

Good luck!

And finally, I found on the Internet a very moving picture of an unidentified young lady (whose face I have pixellated) walking on a disused runway at one of these old airfields.

Look carefully above her head….

*The B-17F didn’t have the chin turret that the ‘G’ had (the twin-gun turret under the nose). The ‘Sally-B’ is a B-17G model.
