Future schemes of air defence

MONSTER EAR TRUMPETS FOR AIR DEFENCE

During the last years of the Great War, sound detectors played an increasingly important part in the air defences of all the belligerents. Since those days they have undergone great development. Here the emperor of Japan is inspecting the huge trumpet-like detectors that work in conjunction with the anti-aircraft guns (seen right)

This last in a series on 'Things of tomorrow' draws upon Boyd Cable, 'Future schemes of air defence', in John Hammerton, ed., War in the Air: Aerial Wonders of our Time (London: Amalgamated Press, n.d. [1936]), 310-6. (There was a seventh in the series, but by another author and on a non-military subject, that of stratospheric flight.) The previous posts looked at 'Death from the skies', 'The doom of cities', 'New horrors of air attack', 'If war should come' and 'When war does come: terrifying effects of gas attacks'.

The necessary madness of air defence

In 1910, two Army officers, Second Lieutenant Bowle-Evans and Lieutenant Cammell independently put forward a new idea for an anti-aircraft weapon: the vortex ring gun.

In principal, it involved the formation of a vortex in the air, by the firing of an explosive charge inside a conical 'gun' which, if it were pointed upwards, would propel the vortex towards the intended airborne target on which, it was suggested, the violent air movement within the vortex would have a sufficiently destructive effect. Some practical support for the theory was provided firstly by a Dr Pernter of Germany who had some years earlier carried out some experimental firings which were said to have torn apart birds and other objects, and secondly by the farmers of a large region ranging from Hungary to northern Italy, who appeared to use such guns routinely in the belief that they could disperse hailstorms.

These proposals seem to have been made to the War Office; in any case a year later the Secretary of State for War, Richard Haldane, was corresponding on the subject with Sir Oliver Lodge, the eminent physicist. Lodge told Haldane that 'I really think the thing is worth a trial', but although he proposed acquiring a vortex ring gun from Piedmont for testing purposes it's unclear whether this ever happened.

The idea of using a vortex ring gun for air defence was aired in public at an Aeronautical Society lecture given on 3 December 1913 by Captain C. M. Waterlow, Royal Engineers, on the topic of the 'The coming airship'. In a discussion of the potential for aerial combat between aeroplanes and airships, Waterlow thought the former would be disadvantaged because of its inferior weight-carrying capacity: the airship could afford to be much better armed. This is perhaps not surprising since he was himself an airship pilot. When it came to the weapons which would be used, he suggested vortex rings:

The question of a suitable weapon had hardly been considered, but he would remark that there were great possibilities in the use of vortex rings, such as had been used in France in connection with vineyards. To show the destructive effects that they can produce, he stated that when fired horizontally they were capable of breaking up a wooden fence at a distance of 100 yards.

The basic principle behind vortex ring guns is quite sound: a smoke ring is a common form of vortex ring, and toy vortex guns can bought or even made at home. Practical uses are a bit more dubious. The use of vortex ring guns (or hail cannon) to disperse hailstorms has a long history but little scientific evidence to back it up. More recently, militaries have looked at vortex ring guns as non-lethal weapons, to knock people down, but they don't seem to be able to do this even over a distance as short as 30 metres.

As it was

Essen, after 5/6 March 1943

Don Charlwood's No Moon Tonight has a reputation as one of the best Bomber Command memoirs. Charlwood was a Victorian who joined the RAAF in 1941, trained as a navigator in Canada under the Empire Air Training Scheme, and then flew in Halifaxes and Lancasters with 103 Squadron at Elsham Wolds. Having survived his tour of 30 ops in 1942 and 1943, he stayed in aviation after the war, albeit on the ground as a civil air traffic controller. No Moon Tonight was originally published in 1956 and was the first of more than a dozen books by Charlwood, some memoirs, some aviation history, some Victorian history. In 1986 he wrote that the book was 'kindly received both in Australia and Britain', and that 'letters from ex-aircrew men of various nationalities began to tell me I had not been alone in my response to the Bomber Command experience'. It's one aspect of that response I'm interested in here: his feelings about the morality of area bombing.

When war does come

When war does come

FORETASTE OF THE FUTURE

Of all the forms of gas used in the Great War, that which had the least disastrous consequences was "tear gas." Its effect was to inflict temporary blindness on those who came in contact with it. This pathetic row of figures show men temporarily blinded in that way on the Western Front in April, 1918. Affecting as this scene is, the results of the deadly gases of today would be infinitely worse.

Another batch of photographs of 'Things of tomorrow'. After 'Death from the skies', 'The doom of cities', 'New horrors of air attack', and 'If war should come', there followed (and note the shift from the indefinite to the definite) Boyd Cable, 'When war does come: terrifying effects of gas attacks', in John Hammerton, ed., War in the Air: Aerial Wonders of our Time (London: Amalgamated Press, n.d. [1936]), 272-4.

If war should come

If war should come

WILL THEY BE A COMMON SIGHT?

Officers of the St. Johns Ambulance Brigade, who, in their black and white uniforms, are familiar and friendly figures to Londoners, are now preparing for the possibility that grim and terrible duties may one day fall to their lot. A number of them have recently received instruction in a hall beneath one of London's biggest blocks of flats in methods of first aid in the streets, in the use of shelters and airlocks and the gas-proofing of private premises. A group of them is here seen clothed from head to foot in anti-gas equipment

These photographs are from the fourth of a series of articles on the future of aerial warfare: Boyd Cable, 'If war should come', in John Hammerton, ed., War in the Air: Aerial Wonders of our Time (London: Amalgamated Press, n.d. [1936]), 201-4. The preceding articles were 'Death from the skies', 'The doom of cities', and 'New horrors of air attack'.

New horrors of air attack

New horrors of air attack

SUCH THINGS WILL HAPPEN

In April, 1935, a Kentish Voluntary Aid Detachment of the British Red Cross Society conducted an air raid rehearsal. Here Red Cross men wearing box respirators and anti-gas clothing are rescuing a woman caught by gas in the open. With a heavy concentration of the deadly gases that modern chemists have now evolved there is little chance she would survive for more than a few minutes.

These images are from Boyd Cable, 'New horrors of air attack', in John Hammerton, ed., War in the Air: Aerial Wonders of our Time (London: Amalgamated Press, n.d. [1936]), 143-6, the third article in a series on 'Things of tomorrow', following on 'Death from the skies' and 'The doom of cities'.

The doom of cities

The doom of cities

RAIN OF BOMBS

Milan's wonderful cathedral is here shown under a rain of dummy bombs dropped by 80 aeroplanes during recent manoeuvres of the Italians. To make the display more impressive and to ascertain the results with more certainty, luminous "bombs" were used and fell in a fiery rain upon the city -- a dire portent of future terrors

The images in this post are from Boyd Cable, 'The doom of cities', in John Hammerton, ed., War in the Air: Aerial Wonders of our Time (London: Amalgamated Press, n.d. [1936]), 96-8. It was Cable's second article in a series on 'Things of tomorrow'. The text doesn't actually connect with the illustrations very well. Cable's main point is given away in the title, that in the next war cities will be ruthlessly destroyed from the air, since 'the murderous slaughter of non-combatants' is the most effective way to force a nation to surrender. While he notes that some experts are sceptical of this (Captain Turner, late of Woolwich Arsenal, Lord Castlerosse, Frederick Handley Page), he argues that 'they are flatly contradicted both by the known facts of the last war and by the preparations which we know have been made in anticipation of the next great struggle'.

Today, and as far as we can see into the future, War first of all means Air War; and Air War spells, literally and actually, the "doom of cities."

Duck and cover, 1942

31 January 2012 in 1930s, 1940s, After 1950, Australia, Civil defence, Cold War, Nuclear, biological, chemical, Pictures by Brett Holman | 7 comments

Brighton Technical School, 1942

This is an image we might particularly associate with the United States in the 1950s, when schoolchildren were taught to duck and cover in the event of the flash of an atomic blast. But its use in civil defence drills predates the Cold War (albeit without a Bert the Turtle to help kids remember the message). I've seen scattered references to it being used in ARP drills in British schools in the the 1930s, and the same thing may well have happened in the First World War. But details, and photos, seem to be rare. The above photo was actually taken in Melbourne, at Brighton Technical School, probably in 1942. (Here's another Australian one from the 1940s, and here's one from London in July 1940.) It's really just common sense: if the roof and walls are about to come crashing down and there's no time to get to a proper shelter, getting the students under their desks when the bombs started to fall would give them some protection and might save their lives.

I wonder about the handkerchiefs or rags the boys have in their mouths? My guess is that it's intended to guard against being choked with dust and plaster. Also, soaked in water, they might help against some forms of gas attack, such as chlorine. Soaking them in urine would be more effective, but that would probably be beyond the scope of most school gas drills!

Death from the skies

Death from the skies

The images in this post are from Boyd Cable, 'Death from the skies', in John Hammerton, ed., War in the Air: Aerial Wonders of our Time (London: Amalgamated Press, n.d. [1936]), 20-4 (see below).

The article itself is a short story describing an air raid in the next war. I won't summarise it in detail, but it argues for the futility of both air defence and civil defence. The RAF's interceptors never even encounter the enemy bombers (in part because they are stealthy thanks to their silenced engines, only 20% as loud as normal aircraft engines). Though the populace has been drilled well and resists panic, at least at first, they are too vulnerable. A first wave of bombers uses high explosives to block the streets with rubble, making it impossible for fire engines to pass; the second drops incendiaries which set the city ablaze and, crucially, force civilians out of their shelters; and the final wave drops poison gas, which starts killing the now-exposed people on the streets. Now the panic starts and the mob flees, their suffering increased by strafing raiders. The RAF now has its chance, but the city is doomed...

"Proof enough of what we've said so long," growled the one [Air Staff officer]. "Defence as such is a wash-out. Attack is the only useful form of defence."

"If we can hit them harder and faster and oftener than they can hit us, we win," said the other. "We can do it, too, if we have more bombers -- men and machines -- than they have."

"Yes -- if," said the other wearily. "That's what we were arguing as far back as the first R.A.F. expansion scheme in -- what was it -- 1935 and '6, wasn't it?"

If, 193-?

12 December 2011 in 1930s, 1940s, Air defence, Art, Nuclear, biological, chemical, Periodicals, Pictures, Reprisals by Brett Holman | No comments

Flight, 25 June 1936, c

In June 1936, Flight published a short story entitled 'If, 193-? A conjectural story'. It's interesting as an example of an air force view of the next war. That is, for the RAF it goes pretty much according to plan: the enemy's attempt at a knock-out blow against Britain fails, whereas the RAF plays a key part in Britain's victory. The author and illustrator, H. F. King, was only 21 or so when this story was published; in July 1940 he became a pilot officer in the RAF, and after 1945 wrote a number of books about aeroplanes (including a couple of entries in the authoritative Putnam series). I don't know what his relationship to the RAF was at this point, but he seems to have been pretty well-informed. Or perhaps he just read his Flight cover to cover every week.

The situation is as follows:

Through indefensible aggression Eurland had secured a number of Continental bases, the nearest being not more 400 miles distant from the English coast. It was apparent that the enemy intended to push his way toward the coast and to acquire additional aerodromes from which to operate all manner of aircraft, including his short-range fighters.

One of the few characters in the story, a planespotting young ship's engineer (perhaps modelled on the author himself) muses that it was 'Funny to be thinking about war with Eurland, of all countries. Still, there was no accounting for the machinations of the politicians'. The reader should NOT identify this 'Eurland' with any real Germany, as an editorial comment makes clear. Did I say 'Germany'? Sorry, I meant 'country'.

THIS story is not intended as a forecast. Indeed, any mention of politics, foreign countries or exact period have purposely been omitted. Rather it is intended to tell something of what might be expected should Great Britain be attacked from the air after her Royal Air Force has been made stronger than it is to-day.

This last sentence gives the game away: the story is an argument for the continuation of RAF rearmament (i.e. the one triggered by German rearmament), which had begun only a year or so earlier. King has a paragraph on how expansion has fared by the fateful year of 193-:

Some of the fighter units were still flying the Gauntlet. More were using the four-gun Gladiator and the improved Fury. The Hawker monoplane was just beginning to percolate into the Service and threatened to turn all fighter tactics topsy-turvy. We had scores of Blenheims, Battles, and Wellesleys, in addition to the obsolescent Hinds and Ansons. Our heavy bombers included the Heyford and Hendon (both due for replacement), the Whitley, and various types of more modern design.

'None of these' latter, King remarks, 'bore any trace of the slackening in the pace of bomber development during 1933, when the British Government recommended restrictions on the all-up weight of bombing aircraft', presumably referring to Britain's proposals at the World Disarmament Conference.
