Air defence

The Royal Air Force is 90 years old today. It was formed from the merger of the Royal Flying Corps and the Royal Naval Air Service on 1 April 1918 (yes, April Fool's Day), as the result of an Act of Parliament. This was historic. The RAF may not have been the world's first independent air force to become independent of military or naval control: the Finnish Air Force apparently beat it by less than a month. But as the FAF started out with just one aeroplane (and that liberated from Sweden), and the RAF with thousands, the British experiment was the riskier. (Particularly given that -- by chance -- it came in the middle of a massive German offensive on the Western Front.) The British example was assuredly more influential than the Finnish, too. Most air forces around the world are now independent, though the fashion took a while to catch on (the Dominion air forces mostly became independent in the 1920s, as did Italy's; France and Germany followed in the 1930s; the US and Japan fought the Second World War without an independent air force).

I've never been able to form a clear picture of just how smoothly the merger between the RFC and RNAS went. One would expect there to be some problems in integrating branches from two services with very different traditions, cultures, routines, doctrines, equipment and so on, but it doesn't seem to have been much of a problem. There were some longer-term issues -- in 1922, P. R. C. Groves complained about former naval men on the Air Staff, who didn't understand the RAF's unique needs, and equally complained that the RAF still had an Army mindset, at least partly a dig at Hugh Trenchard, a late convert to the idea of an independent air force (who had always been devoted to the Army's needs during the war, and in Groves's view, at least, had obstructed the work of the Independent Force while its commander in 1918). Since the RFC was much larger than the RNAS, this was probably inevitable to start with. Certainly for the first few years of its existence, the RAF had Army-style ranks, and allowed its officers to wear their RFC khaki uniforms until they wore out (which they were probably keen to do, as the first RAF uniform was a very unpopular pale blue). In 1919 the RAF adopted its own rank structure, actually more reminiscent of the Navy's -- 'flight-lieutenant' came directly from the RNAS, where it was a simple modification of the equivalent rank of 'lieutenant'; 'group captain' is equivalent to the Navy's 'captain', and both are much higher in rank to the Army's 'captain'. Of course, the senior services were jealous of their new sibling: there was a concerted attempt to smother it in 1921. This failed, but eventually the idea that the air was indivisible was eroded. The Fleet Air Arm became part of the Navy in 1937, partly undoing the unification of 1917. And in the Second World War, the Army began to acquire some air assets too (twelve squadrons of observation aircraft, lots of gliders).

It's the 75th anniversary of Stanley Baldwin's famous 'the bomber will always get through' speech. It's an important text which is widely quoted, both in my primary and my secondary sources, as a testament to the fear of bombing in the 1930s. But I've never actually read it very closely, and I think I'm in good company because it's usually the same couple of lines which are quoted, and the rest of it is ignored. And as it doesn't seem to be online anywhere I thought it would be a useful exercise to transcribe it and put it up on the web.

Baldwin was not Prime Minister when he gave the speech, as is sometimes said. He had been PM twice before, in 1923-4 and 1925-9 (and would be again in 1935-7), but at this time he was Lord President of the Council, a Cabinet-level post with no major duties attached to it. Baldwin's real importance was as leader of the Conservative Party, which had by far the most seats in Ramsay MacDonald's National Government. He had power without responsibility, one is tempted to say.

The occasion for the speech was a debate in the House of Commons about disarmament, held on 10 November 1932 -- the eve of Armistice Day. The original motion was proposed by Clement Attlee, deputy leader of the Labour Party, and read:

That, in the opinion of this House, it is an essential preliminary to the success of the forthcoming World Economic Conference that the British Government should give clear and unequivocal support to an immediate, universal, and substantial reduction of armaments on the basis of equality of status for all nations, and should maintain the principles of the Covenant of the League of Nations by supporting the findings of the Lytton Commission on the Sino-Japanese dispute.1

This was obviously an attempt to embarrass the Prime Minister, a well-known pacifist -- and a hated former leader of the Labour Party. But MacDonald didn't speak in the following debate; instead, his Foreign Secretary, Sir John Simon, defended the Government's record and went into some hopeful diplomatic initiatives in some detail. George Lansbury, Labour's leader, lashed out and accused all nations of failing to fulfill any of the international peace pacts signed since the war. Baldwin spoke last of all. According to the Times's parliamentary correspondent, when he finished 'There was a deep and almost emotional round of applause' from the House.2 Of course, he was the party leader for most of the MPs, but it does seem that he had touched a chord. Baldwin had a longstanding record of concern about the air threat and his sincerity would have been evident. And -- not that there was ever any doubt given the huge majority enjoyed by the National Government -- Attlee's motion was defeated by 402 votes to 44.

The following transcript of his speech is taken not from Hansard but from The Times.3 I've edited it lightly, mainly to move the murmurs of approval from the listening MPs into footnotes. The phrases in bold are those which are most commonly quoted.

The Sky's the Limit

This is the front cover of a book by J. M. Spaight on British airpower, called The Sky's the Limit. It was published in 1940, a not-insignificant year for the RAF. In fact, this 'New and up-to-date' edition was published in August, right in the middle of the Battle of Britain. (The first edition was published prior to the fall of France, judging from the number of references to the Armée de l'Air, now in the past tense.) It's a familar image -- the young fighter pilots sitting in their Spitfires on a glorious summer's day, standing by for the word from Ops to hurl themselves into the sky to repel the hordes of Nazi invaders. In fact, it's almost iconic. But hang on -- something's not quite right here. Take a closer look at the aeroplane in the background:

Last year I was playing with a plotting program for Mac OS X, which was pretty good, but not quite satisfactory. I've found a better one, Plot, which is free (as in beer), fairly easy to use, and very customisable. It has its own idiosyncrasies, but I like it a lot. Here's an example plot, showing how the top speed of British combat increased up to the end of the Second World War.

Maximum speed of British combat aircraft, 1912-1945

The data are drawn from John W. R. Taylor, Combat Aircraft of the World From 1909 to the Present (New York: Paragon, 1979). This excludes aircraft which never saw service as well as those not intended for combat (though not all actually saw combat). The year is that in which it entered service (usually with the RAF), or if this wasn't given, the year when the prototype first flew. (Some aircraft unfortunately had neither, and so were omitted.) The maximum speeds, in miles per hour, are not necessarily comparable, because they were often obtained at different heights; also, they may not have been sustainable under normal conditions. But they should be broadly indicative of real-world maximums. I've classified each aircraft as either fighters (red) or bombers (blue), based upon their actual use. However, that's fairly arbitrary for the period up to 1915, which is when aircraft adapted for specialised roles began to appear. I haven't included seaplanes but I have included carrier-borne aircraft. Generally, I have only included data for the most representative version (eg not for each of the innumerable marks of Spitfire). Because of these caveats and inconsistencies, the plot should not be taken too seriously -- it's just for illustrative purposes.
