The majority of the coverage is on the electronic war between England and Nazi Germany as they developed competing systems to aid their respective bombing campaigns and the countermeasures that arose in the form of improved aerial radars and passive reception devices. It's strengths include interviews with many of the participants in this obscure form of combat and the amount of information provided on the incredible array of devices and gadgets developed for electronic combat between 1939 and 1945.Although he does have several chapters covering US work and the Pacific War, these areas are better covered in the series he later wrote on US EW History for the Association of Old Crows. Over 60 years later the basics of EW really haven't changed, which makes this book still important reading for anyone interested in the dark arts of electronic warfare.
The actual events could have been described better. There was excitment but book wasn't very exciting.
This book demonstrates the profound effect that electronics had on the war in Europe and the Pacific.
Another excellent book on electronic signals intelligence or SIGINT is "Most Secret War" by R. V. Jones (1978).
forces and German and Japanese units. The author makes clear the importance of these techniques in both offensive and defensive actions, especially in air combat .
For a good discussion of US work during the same time period and after, see Robert Buideri's "The Invention That Changed the World".

Highly-recommended.

1. Such books set a benchmark for books on topics that are technologically complex but can be explained to a layman to give a rudimentary idea.
2. Another commendable fact about the book is that it is focused on the radar system evolution in a spam of 5-7 years and hasn't tried to squeeze multiple topics.
3. The book is almost neutral in it's evaluation of achievements of all the sides. It doesn't preach or make claims about morality, it stays focused on the subject.
4. I hold the opinion that the Allies were 'allies' to a considerable extent but the Axis Powers were almost isolated (well, Germany did came to Italy's rescue in Africa!) on various fronts. The book highlights how the Americans and the Brits mutually benefited to some extent by coordination while the Axis powers did too little, too late.
5. The readers get an idea about the people who made radars a reality and the aircrew who used it.
Like any war or revolution in any field, radar evolution was a series of systems, improvisations, innovation, failures. The book explains in brief the prominent radars, their fundamental functioning, usage and how it was countered. Personally, I like such presentation of facts.
The book details the field challenges and dangers faced by the operators and fighter pilots, the race against time that the scientific and engineering personnel were incessantly subjected to, the correlation and deduction methods (e.g: labels on German electronic devices to guess no. Of devices in use), how Intel. sharing helped the radar scientists, the cat-and-mouse game of deception.
The book has some limitations:
1. While I appreciate it's focus on radars, 'electronic warfare' is a broad term, which, IMHO, should also include the cryptography/encryption systems. The title is misleading and should be changed to clearly state its focus
2. The writer's RAF background makes it obvious what the focus would primarily be, however, the radar usage and events in the navies(on both sides), the Russian radars(however primitive), the budget and other monetary aspects of radar research and production and many such aspects aren't even highlighted.
3. Establishing a timeline of events, the various radar systems is quite difficult while reading this book. When did the battle of Britain begun, when did it end, when did the bombings of Germany begun - these dates are spread across chapters which doesn't allow the reader to form a coherent timeline, the focus keeps on tossing back and forth.
4. Too less diagrams of radars and operational concepts, given the no. Of systems and events covered.
Overall, this book should be present on shelf of every WW-II enthusiast(at least, the noobs like me).



Even though the 1st recorded incidences of Electronic Warfare occurred during the American Civil War when the combatants tapped each other’s telegraph communications, it was really during the Second World War that Electronic Warfare came of age with both Germany and Britain in the forefront of Radar development as the war commenced. Price’s book tells this story and how measure and counter measure continually leap-frogged though by the end Britain and the US were, as Goering would admit, able to outpace the German efforts.
Price did not have access to some of the material available to R V Jones but his story remains equally fascinating and excellent reliance is placed on the work of the author of the 1st edition’s preface, Dr Robert Cockburn of the Telecommunications Research Establishment. The book begins with the attempts in August 1939 of the Graf Zeppelin airship equipped as the world’s first airborne electronic intelligence, or Elint, collector, attempting to evaluate the RAF’s Radar system and comprehensively failing to do so not because it wasn’t there but because they made the error of thinking the British would use the same frequencies as the Germans for Radar, a mistake the British would benefit from and would themselves not make.
In Britain, the likes of Cockburn and Jones were not as bound by paradigms as the Germans which allowed them to identify and successfully jam Knickebein ( which ‘surrendered almost without a fight’) X-Gerät and ϒ-Gerät in the Battle of the Beams in 1940/1. From the ‘Battle of the Beams’ and the piecing together of the operation of the Reich Air Defence system, covered by Jones, Price adds to the picture by going onto the offensive use of EW so here is told the story of the development of the Mandrel jammer, to screen RAF attacks, and its initial deployment in Boulton Paul Defiants. Indeed, that whole development of the RAF Bomber offensive electronic battle with the Luftwaffe is grippingly told.
By the war’s end, each RAF heavy raid was a sophisticated and complex plan with Radar led Pathfinders, spoof raids by Mosquitos (usually identified as such by the Luftwaffe as the Mosquitos emitted no H2S transmission unlike the heavy bombers) and by Heavy Bombers, or even multiple heavy raids. During the raid, direct jamming by Mandrel carried within the bomber stream (often in B17s) would occur whilst engine noise from all bombers would be transmitted on German GCI frequencies via ‘Tinsel’ and same bombers would drop ‘Window’. Later ABC Lancasters of 101 Sqn would fly in raids with German speaking operators mimicking GCI controllers. As this was going on Serrate equipped Mosquito and Beaufighter night fighters would lurk in the stream homing on the transmissions of German night fighters to shoot them down. Navigation and bombing accuracy would outclass that of the 1940 Luftwaffe as the RAF developed and used Gee and Oboe.
Of course, the Germans did take countermeasures to all this. Tactically the introduction of fighters into the bomber stream using Wilde Sau and then Zahme Sau to counter the effect of Window was effective, particularly when the Zahme Sau aircraft were fitted with ‘Naxos’ which ironically homed on the RAF bomber’s using ‘Monica’ fighter approach warning device! (when the RAF belatedly realised this when evaluating a captured Ju88, Harris insisted Monica was removed from all aircraft immediately. The RAF’s transmissions of jamming and radar emissions was often the cause of the death of the bomber crew as any transmission could be homed on and H2S allowed the tracking of the bomber stream even through ‘Window’. Nevertheless, Price’s evaluation is that ‘the various jamming methods reduced RAF bomber losses between December 1942 and the end of the war by something of the order of one per cent. Yet, over an extended period, that amounted to a saving of more than 1,000 bombers and their crews.’
Whilst the RAF’s battle against the Luftwaffe forms the core of this book, the USAAF is not left out. Over Europe, there was obviously no point in trying to hide from fighters in daylight. Nevertheless, the problems of bombing accuracy through the North European overcast existed for the USAAF as it did for the RAF hence the adoption of H2S and its derivative H2X by the day bombers. Against Radar directed Flak ‘Window’, known as ‘Chaff’ by the Americans, was particularly effective. Price’s evaluation is that ‘When cloud or (over Japan) darkness forced AA gunners to rely on radar-controlled fire, jamming greatly reduced its accuracy. As a ‘ball park figure’, radio countermeasures probably saved about 600 US heavy bombers over Europe, and a further 200 during operations against Japan.’
Price’s conclusion is that during the war there were 2 occasions when allied ECM (RCM in the terms of the day) brought about a near-collapse of an enemy air-defence system. ‘The first was the devastating initial effect of ‘Window’ on the German air defences at the end of July 1943. The second was over Japan in 1945, when the USAAF jamming paralysed the Japanese night-air-defence system. For the rest of the conflict radio-countermeasures brought about a somewhat smaller, though still significant, reduction in bomber losses.’ It is hard to disagree that the Allied radio-countermeasures effort during World War II was ‘a remarkably cost-effective investment.’
This book is a fascinating read that I cannot recommend highly enough.
