The story behind the technology that revolutionized both aeronautics, and the course of history

On a moonless night in January 1991, a dozen airplanes appeared in the skies over Baghdad. Or, rather, didn't appear. They arrived in the dark, their black outlines cloaking them from sight. More importantly, their odd, angular shapes, which made them look like flying origami, rendered them undetectable to Iraq's formidable air defenses. Stealth technology, developed during the decades before Desert Storm, had arrived. To American planners and strategists at the outset of the Cold War, this seemingly ultimate way to gain ascendance over the USSR was only a question. What if the United States could defend its airspace while at the same time send a plane through Soviet skies undetected? A craft with such capacity would have to be essentially invisible to radar - an apparently miraculous feat of physics and engineering. In Stealth, Peter Westwick unveils the process by which the impossible was achieved.

At heart, Stealth is a tale of two aerospace companies, Lockheed and Northrop, and their fierce competition - with each other and with themselves - to obtain what was estimated one of the largest procurement contracts in history. Westwick's book fully explores the individual and collective ingenuity and determination required to make these planes and in the process provides a fresh view of the period leading up to the end of the Soviet Union. Taking into account the role of technology, as well as the art and science of physics and engineering, Westwick offers an engaging narrative, one that immerses readers in the race to produce a weapon that some thought might save the world, and which certainly changed it.

I wonder if the book contains any illustrations...
Is it possible to reproduce invisible aircraft on pictures? :cool:
 
Looks like it is going to be an interesting book. Going to be a long time to wait however.
 
A rather dramatic write-up. A review of early flying wings built by Northrop shows the difficulty of picking them up on radar. I suggest getting a copy of Jack Northrop and the Flying Wing - The Real Story behind the Stealth Bomber by Ted Coleman with Robert Wenkam. Mr. Coleman was a close associate of Northrop's at the company.

I'm not really convinced that the B-35 and B-49 would have invincible on radar had they gone into production. Also bear in mind that the SR-71, with its chines, could easily escape detection by enemy radar at high altitude, something the U-2 couldn't do. We'll see if this book mentions the SR-71, because most popular and semi-technical books consider the F-117 the first stealth aircraft.
 
Be interesting to see how far they trace the history of each company's interest in low-observables. I've heard, from the then-Northrop Historian (Dr. Ira Chart) that Northrop's first real interest in low-observables came about from the difficulty in tracking Snark missiles in flight.
 

He's a historian rather than an aviation author, so might focus more on people and politics rather than technical details. We'll have to see.

No-one has ever suggested the B-35/B-49 were invisible to radar. They were harder to spot than the B-36 / B-47 on radar, with a lower detection range, but not operationally significant enough to make a difference.
 
Hi, new member here. I came across this thread while searching the web for an advance reading copy of this book. I found one, and just finished reading it. Westwick's book is quite comprehensive and well written. As a historian of the California aviation industry, he mostly approaches the topic from that perspective, and his sources were largely players from Lockheed and Northrop---John Cashen, Irv Waaland, Jim Kinnu, Alan Brown, Sherm Mullin, etc. He's a little weak on government sources although he did an extensive interview with Paul Kaminski. And yes, he does go into the Snark, the relationship between the B-2 and YB-49, the entire history and science of radar reduction, etc., but the focus, as you'd expect, is on Have Blue, Senior Trend, Tacit Blue, and the Senior Ice/Peg competition.

Now that I've read it, I'd be happy to pass it on to anyone willing to pay the shipping. By the way, if you're interested in this topic, Westwick runs the Aerospace Oral History Project at the Huntington Library, and has posted transcripts of many of his interviews there. Well worth a look.
 
I noticed in a list of illustrations in this book, there is a sketch of the Lockheed BSAX design. I don't know if I've ever seen that one.
 
Long time since I read anything on LO technology, so might just treat myself to a copy. Does it look at British RAM such as DSX, DSI, RAM-D and RAM-L?

Chris

PS before you ask, RAM-D and -L aren't Soviet aircraft.

No, it doesn't.

I'm not sure what exists in the public archives but there are definitely some historical reports of UK research and measurements on a number of aircraft that exist. If there's a searchable function you might want to look for "radar echoing area" that was historically used rather radar cross section.

Everybody always forgets Convair/General Dynamics., :confused:

Not me sferrin, I always liked the Convair/General Dynamics designs especially the Fish/Kingfish design that went up against the Lockheed Skunk Works A-12.
 
Is there any mention in the book about LRCS helicopter development or testing? Another part of the story that is constantly overlooked.

500 Fan.
 
Its not a general book on Stealth. It's squarely about Northrop and Lockheed, and their work on Have Blue/ XST, F-117 and Tacit Blue.
 
Thanks. I think Northrop did some support work on a Government test program for a LRCS experiment on helicopters in the 1970's. Thanks.

500 Fan.

No, no mention of that.
Some mention of Snark, RVs, some other things before going into XST.

I do not think I have seen much public discussion of the low RCS rotorcraft programs of the 70s and 80s. Ed Lovick mentions some experiments he did (not part of an official program) in his book, that's about it.
 
I just finished reading this. As noted above, the book focuses on the XST/F-117, Tacit Blue and B-2 projects. It gives an insight into the different approaches Northrop and Lockheed used, which was eye-opening to me: I've always thought of the F-117 as a first-generation design, and the B-2 as a second-generation design benefiting from advances in computing that allowed more complex shapes to be analyzed for RCS.

This book shows Northrop used curved shapes from the beginning, including in its XST design. They found out that radar returns are dominated by the edges of a shape, and used an iterative build/test program to get to a shape that worked. Lockheed in contrast went all-in on CAD using its ECHO program, which was limited to flat planes.

The book is well-written and easy to read. There are few illustrations, and it doesn't go into detail design much (no mention of the serrated edges on the opening panels, for instance). The book is shorter than I expected: it has 250 pages, but page 190 is the end of the content. There's an extensive bibliography and index.
 
Just remember, without Pyotr Ufimtsev's revolutionary work in using fractals to model how radar signals reflect off a surface stealth might never have gotten where it is. It was his seminal work, Method of Edge Waves in the Physical Theory of Diffraction, that resulted in Lockheed's engineer Denys Overholser, recognizing that Ufimtsev had invented the mathematical basis to accurately model how radar waves would reflect off a finite surface. Thus, stealth was born.
 
Yep, Westwick's book mentions Ufimtsev's work. Ironically, his paper was translated at the request of a Northrop engineer who'd seen a summary and got intrigued.

More importantly, Ufimtsev's work wasn't considered important by the Soviet government so they allowed him to openly publish it and disseminate it internationally.
 
I seem to remember a 1980s magazine article about a pusher prop carbon fiber airplane with a V tail that an airport radar had trouble finding. Not meant to be stealthy, just light. I lost a lot of books and mags due to plumbing disasters

Probably the Lear Fan.
 
Recommend this book I am reading at the moment .... though I have read other books on the topic, this one by far have all the important history recorded in one book ....

Finished up the book over the weekend. I guessed I was able to read so fast due to some familiarity with the subject.

Note that the book came out in 2020, so very little mention of the B-21....

My airframe instructor said that his Long-EZ was hard to track by the regular control tower systems.

Its basically just about Lockheed and Northrop, as well. Not a history of Stealth, per se.
