AUTHOR’S NOTE

I

n this book German words have been anglicised where appropriate. Thus Gunther has been written as Guenther, Kothen as Koethen and Bohlen as Boehlen. Where measurements are given they are in Imperial measures, with converted figures being rounded out where appropriate. Where Japanese Navy ranks are stated, they have been translated to their nearest U.S. Navy equivalent. On several occasions the authors found great difficulty in marrying the British, American, German and Japanese records concerning actions involving jet aircraft. Frequently the claims from one side bear little or no relation in time or place to the losses admitted by the other. For this reason claims and losses have been linked in the text only where there is clear evidence for doing so; where there is no positive link claims have in most cases been omitted.

combat over a long period during World War II: the Messerschmitt 163, the Me 262 and the Arado 234. The new book covers all of that ground, plus a lot more. It includes descriptions of the development and combat careers of three other jet aircraft types that saw action during the conflict, the British Gloster Meteor, the Japanese Yokosuka Ohka and, by the narrowest possible margin, the Heinkel 162. It also tells the stories of the two American and one German jet aircraft that had entered squadron service and were on the point of going into action when the war ended: the Lockheed P-80A Shooting Star, the Ryan FR 1 Fireball and the Bachem Ba 349 Natter. This work takes the reader through the most rapid period of scientific advance in the history of aviation: from the beginning of the jet age to the

aircraft; in each case new designs that were liable to suffer the teething troubles that inevitably go with such things. Thirdly, and in the short term more intractable than the other two, there was the little-understood phenomenon of compressibility that manifested itself as speeds nudged ever closer to the invisible 'sound barrier'. All of this took place against the background of all-out war in which major nations were battling for their very survival. In the certain knowledge that the enemy was also working on these problems, and might find the answers first and reveal their discovery with devastating effect, there was no time for carefully staged test programmes seeking incremental advances in knowledge. It was a callous world in which test pilots, and often service pilots as well, were

world, there were strong pressures to improve the performance of military aircraft and in particular fighters. Secondly, and stemming from the first, there was a dawning realisation among aircraft designers that the immutable laws of physics would prevent propeller-driven planes from attaining speeds above 500 mph. The fundamental problem stemmed from the use of the propeller as a means of converting rotational power into thrust: as speed increased, the propeller's efficiency fell drastically. A few figures will serve to illustrate the point. In round terms, the Spitfire attained a maximum speed of about 300 mph at sea level with an engine that developed 1,000 horsepower. At that speed the propeller was about 80 per cent efficient and the 1,000 pounds of thrust that it produced equalled the drag from the Spitfire's airframe. Now consider the engine power needed to propel the same airframe at twice that speed, 600 mph. Drag rises with the square of speed, so if the speed was doubled the drag was quadrupled.

engine to drive the aircraft at that speed required not 6,400 horsepower, but 12,000. In 1945 the best piston engines available for fighters produced a fraction over one horsepower for each pound of their weight. Thus a piston engine developing the power to propel our notional fighter at 600 mph would have weighed about 11,000 pounds — about double the all-up weight of an early production Spitfire. For flight at high speeds the turbojet engine or rocket motor were fundamentally more efficient forms of power plant. They produced their thrust directly, with no conversion losses. The thrust developed by the jet engines remained more-orless constant throughout the aircraft's speed range. The BMW 003 turbojet fitted to the He 162 delivered 2,028 pounds of thrust for a weight of less than 1,400 pounds, and gave the fighter a maximum level speed of 562 mph. No pistonengine and propeller combination offered a thrustto-weight ratio that was in any way comparable, and it was clear that their days were numbered for use in high performance aircraft.

CHAPTER 1 The Messerschmitt 262

I

n the history of aviation few aircraft have been the subject of greater controversy than the Messerschmitt Me 262. Several commentators have drawn on its history to demonstrate the military ineptitude of Hitler and other German leaders

who, it is said, failed to push its development with the necessary vigour or use the aircraft in the right way. Some have even gone so far as to suggest

optimistic prediction.
