Google Boats?

According to a news piece posted by AOL, Google is developing the ability to track and display the locations of ships at sea.

All of them.

Well, at least those actively using AIS transponders, but still.

This is a pretty interesting development, if you ask me.  Some of the benefits are obvious, and are mentioned in the article.

Then there's the fact that you could theoretically track the movement of military forces worldwide.  Provided they operate with AIS transponders active, that is.

I'd think that this represents a great tool to exploit off of the Horn of Africa.  Military vessels in the area with transponders active could act like homing beacons for shipping in the area, guiding them through protected waters and serving as a pirate deterrent.  The authors naturally assume that such new technology would obviously represent some sort of terrorist tool for attacking targets (because what else is Google Earth but a mapping program of terrorist targets, right?), but if American, Chinese, or whoever's naval units are operating in the clear, hey, go ahead and try it.  I'm willing to bet that in the battle of terrorist vs. 5 inch round or terrorist vs. CIWS, the winner will not be the guy with nefarious intentions.  Plus, in case they haven't noticed, terrorists and pirates are already attacking boats.

The really interesting bit of the article is Google's plan to map the entire seafloor in high resolution over five years.  Again, the assumption is that this will lead to all sorts of security problems when crashed spy satellites are located and the Chinese or Russians go out to lift them off the bottom.  Always with the negative waves, Moriarity.  Always with the negative waves.  Me, I'd like to see them locate Jack Weeks' A-12, to finally put an end to one of the unsolved tragedies of the CIA's OXCART program.

Of course, locating K-129 would be amusing too...we'd then know just how much of the sub was lifted off of the bottom by the CIA.  I'm not sure which would be more amusing, finding only a few pieces of the sub on the bottom, or the entire thing.

The article closes with the following line from an unnamed intelligence community source, after a brief bit about how Google services have little intelligence utility whatsoever in their minds:  "Just because you have the data, doesn't mean you can analyze the data or know how to use it."

Sure, I'll take that as a challenge.  Or maybe a mission statement...

And see?  I told you I'd be posting here again.

The Blackbird Reading List

INTRODUCTION

Blackbird. Habu. Cygnus. OXCART. SENIOR CROWN. Anyone with even a passing interest in Cold War military history or aviation history knows what those names represent. This reading list will provide historians, researchers, and aviation fans with some of the best reading materials and reference sources available on these most fascinating of aircraft. All of these titles have been taken straight from the author's personal library (in other words, this is not meant to represent every single published work, just the ones that I've bought and read) and will be reviewed in brief. Titles will be divided by decade, demonstrating to an extent how they seemed to land on the market in bunches, ostensibly due to the discovery or release of new information previously unavailable.

THE 1980S

Blackbird-related titles began to arrive on the shelves in earnest in the 1980s. The aircraft had been operating for a sufficient length of time for authors to start devoting attention to Lockheed's Mach 3 legends. The addition to the USAF Museum of the surviving YF-12A in 1979 also precipitated speeches by key personnel divulging further information. The main sticking point about the 1980s was that not much was known about the CIA's Blackbirds, and details of their operational exploits were still highly clasified for the most part. The first photographs and basic details of CIA-operated Blackbirds were released in 1982, nearly 15 years after Agency operations concluded.

SR-71 Blackbird in action, Lou Drendel, 1982 My first Blackbird book! Not much more than a photo chronicle, it does provide some details on flying the Sled thanks to interviews with crewmembers, and provides the first bit of speculation on what exactly the A-12s sitting in the California sun at Palmdale were for. A very brief section also theorizes on the purpose and operation of the D-21, accompanied by the sole photo of the M-21/D-21 combination released for publication at the time.

Lockheed SR-71, Jay Miller, 1985 This Aerofax title seems to be one of the more sought-after titles on the Blackbird. Apparently tailored more towards the modeling community rather than the enthusiast community, a number of detail photographs highlight this book, showcasing such airframe bits as the nacelles, landing gear, and canopies. The text is naturally a bit sparse being that this is primarily a photographic work, but some interesting bits of data, such as a complete production list of all Blackbirds, were included.

Lockheed SR-71 Blackbird, Paul F. Crickmore, 1986 Crickmore's first Blackbird work (as far as I know) and arguably the best book written on the subject for many years to come. I first ran across this one in the library at 2 ATAF HQ at RAF Rheindahlen in the mid 80's and was determined to find a copy. Coming in at 200 pages, it contained the most detailed look at the entire program published during the '80s. A brief paragraph even mentioned CIA operational sorties out of Kadena with the A-12.

Lockheed Blackbirds, Anthony M. Thornborough and Peter E. Davies, 1988 Not much is included in this work, which covers both the Blackbird and the U-2/TR-1 families, that isn't found in far greater detail in Crickmore's work. However, some large three-view drawings are provided which are pretty impressive, with different three views provided for the YF-12A, "M-12" (the M-21 designator hadn't been discovered yet), and SR-71, with scrap side views of the A-12, "A-12 two seater" (again, TA-12, undiscovered), and SR-71B provided as well.

By the end of the 1980s, when the Blackbird program was nearing its first official end, the reference works available provided a great deal of insight into the YF-12A and SR-71 development and operational histories. It was also becoming known that the CIA had something to do with flying single-seat Blackbirds around in the Far East, and that they were trying to do strange things with what basically amounted to the World's Fastest Biplane (thank you, I'll be here all night) as well.

THE 1990S

Three significant books on the Blackbird appeared in the 1990s, basically due to an increase in interest coinciding with the brief return to operational service of the SR-71A. By this time far more information on the A-12 program had been declassified, allowing a much clearer picture of the CIA's operation of the Blackbird to be presented for the first time.

SR-71 Blackbird, James Goodall, 1995 Aside from Crickmore's 1986 work, this became a standard reference for the Blackbird until the 21st Century. A great deal of information on the CIA's Blackbird operations was included, as well as a host of new photographs. This also marked the first time that the SR-71A Big Tail modification was detailed in a Blackbird book.

SR-71 Revealed: The Inside Story, Richard H. Graham, 1996 Who else but a former Sled driver, who became a Blackbird squadron commander and later the commander of the 9th Strategic Reconnaissance Wing, would be a better choice to pen a book on the SR-71? After reading Col. Graham's book, the answer is nobody. Col. Graham tells the Blackbird's story the way only an insider can, from his recruitment into the program, all the way to the politics behind the Blackbird's retirement while he was the 9th SRW's CC. This book is not a purely technical overview, with the Blackbird's family history relegated to a mere four pages, but rather a detailed accounting of the program from a pilot's perspective. Col. Graham's personal tales and anecdotes are what make this a must-read for any Cold War aviation enthusiast.

Lockheed SR-71/YF-12 Blackbirds, Dennis R. Jenkins, 1997 At first glance there doesn't appear to be much in the way of new textual information that Jim Goodall didn't cover in 1995 in this book. However, the real strength of this book was the inclusion of a great deal of technical schematics and reference drawings taken from flight manuals and other official sources. Many of these dealt with the YF-12, including schematics detailing the loading procedures for inserting AIM-47 missiles into the weapon bays.

2000-2010

With the turn of the century, the Blackbird again found itself out of operational service, and no longer in use by NASA. Despite the fact that no Blackbird would ever take to the air again (unless somebody wants to convice Bill Gates or Richard Branson that it'd just be really fun to restore one to flying status for the airshow circuit...anybody?), newly declassified information began to flow out of the CIA and SENIOR CROWN coffers with more regularity. This was in part due to the fact that the aircraft family was completely out to pasture, and likely in no small part due to the fact that researchers were continuing to bombard the relevant FOIA offices with requests for information!

A-12 Blackbird Declassified, Jeanette Remak and Joseph Ventolo Jr., 2001 The first Blackbird-themed book to emerge in the 21st Century was certainly one of the finest. It was also the first book to deal primarily with the A-12 program. Making through use of newly declassified information, a nearly complete operational history of the aircraft with the CIA was reconstructed, as well as numerous flight test details. Token mention of the USAF's KEDLOCK and SENIOR CROWN programs is made, as well as a brief overview of the TAGBOARD/SENIOR BOWL experimentation with the D-21 drone.

Combat Legend: SR-71 Blackbird, Paul F. Crickmore, 2002 This work was part of a series called Combat Legends published by Airlife. It reads like an abridged and updated version of Crickmore's 1986 work, and is bolstered by numerous color profiles.

Lockheed's SR-71 Blackbird Family, James Goodall and Jay Miller, 2002 This is a thoroughly updated and greatly expanded edition of Jay Miller's first Aerofax title from the 1980s, and is not to be missed. This work probably made the best use of the declassified material available at the time, covering the design process of the A-12 in far greater detail than any previous work. This is one of the few Blackbird books that still stands up even today, due to the wealth of historical and technical data included. This was also the first publication to depict some of the declassified schematics for armed SR-71 iterations.

Lockheed SR-71 Blackbird, Bill Holder, 2002 This book is nothing special, featuring minimalist text and too many poor-quality images. This one is only recommended for the serious collector, and can be overlooked by the researcher or historian. One interesting inclusion, however, is a series of photos depicting most of the Blackbirds at their display locations at the time of publication. This, of course, precipitated my own campaign to eventually photograph every surviving Blackbird myself.

SR-71 Blackbird Walk Around, James Goodall, 2003 This title is exactly what it sounds like, a photographic history of the Blackbird family. While there are a number of detail photographs like the title suggests, there are also a number of in-flight and static images as well. If there is a detail feature of the Blackbird, it is likely covered here, including the different cockpit configurations of nearly every variant. This should be regarded as the primary source for any modeler interested in creating the Blackbird.

Lockheed Blackbird: Beyond the Secret Missions, Paul F. Crickmore, 2004 A revised edition of a Crickmore book I managed to somehow miss, this is a serious volume and should be on the shelf of every Blackbird enthusiast. At 400 pages this is easily the largest book on the Blackbird family yet published. Nearly every operational detail is covered, and the development and test histories of the aircraft programs are certainly not glossed over. The real strength of this book is in the descriptions of various operational sorties flown by Blackbird crews around the globe, as well as intercepts flown by Soviet and Russian interceptor pilots. The interview with a former MiG-31 pilot is very nearly worth the cover price alone.

Lockheed Blackbirds, Tony R. Landis and Dennis R. Jenkins, 2004 This is an expanded and far better illustrated version of Jenkins' 1997 book. Many new photographs are included from Tony Landis's collection of Blackbird images, and there are a host of new technical diagrams as well.

Lockheed SR-71 Blackbird, Steve Pace, 2004 This was a welcome addition to the Blackbird library. Pace's work is a well written, relatively concise history of the Blackbird family, backed up by numerous data tables describing test occurrences (such as AIM-47 firings), and significant historical references (such as Kelly Johnsons's A-12 flight log, albeit in an abridged form). The most interesting section details numerous unbuilt Blackbird iterations, many of which were meant to be armed. A hypothetical F-12B intercept scenario is also included. While there isn't much "new" information when compared to earlier works, the presentation and the interesting bits mentioned above still make this an interesting and worthwhile read.

Lockheed SR-71 Operations in the Far East, Paul F. Crickmore, 2008 Crickmore returns to the Blackbird with Volume 76 of Osprey's Combat Aircraft series. This is an up-to-date reference detailing the operational service of the A-12 and SR-71 flying reconnaissance sorties over targets in the Far East. This is basically an abridged update of his last work, making use of the most up-to-date declassified information available. In this case, the history of the aircraft is only briefly detailed, as the focus is on the operational side of things.

Flying the SR-71 Blackbird: In the Cockpit on a Secret Operational Mission, Richard H. Graham, 2008 Colonel Graham, in his second Blackbird book, provides the reader with a step-by-step look at flying an operational sortie in the SR-71A. Each chapter is broken down based on the pilot's checklist steps for that particular segment of the sortie. This is a unique and insightful look at actually flying the Blackbird and includes numerous historical bits and amusing stories from Colonel Graham's Blackbird career.

From Archangel to Senior Crown: Design and Development of the Blackbird, Peter W. Merlin, 2008 For the first time, an author has decided to focus entirely on the technical and technological aspects of the Blackbird family. Merlin's work is outstanding, the only complaint being that this could have easily surpassed 500 pages! While the text is outstanding and well researched, the real treat is the included CD containing numerous flight manuals, documents, images, and videos. The information here is substantial and valuable enough to almost make the book an afterthought, but that would be to ignore the well written insight into the technology of the Blackbird family that Merlin has authored.

The Archangel and the OXCART, Jeanette Remak and Joseph Ventolo, 2008 Remak and Ventolo have provided us with a complete rehash of their 2001 work, incorporating a host of newly declassified material. The most interesting new bits and pieces deal with the ECM systems on the A-12. There are a lot of issues with the editing, but Jeanette Remak has been kind enough to explain them here. Any Blackbird enthusiast would be well advised to see past these issues and pick this up, as it represents the most detailed look at the A-12 published to date.

Archangel: CIA's Supersonic A-12 Reconnaissance Aircraft, David Robarge, 2008 This is the printed version of the official CIA history of the A-12 published online in 2007 here. It is a concise look at the Agency's involvement in Mach 3 reconnaissance.

Lockheed SR-71 Operations in Europe and the Middle East, Paul F. Crickmore, 2009 Crickmore's most recent work is a companion piece to his 2008 volume on operations in the Far East. Primarily focused on operations out of RAF Mildenhall, sorties staged from the United States over the Middle East are also detailed. This book reads like a second volume of his 2008 book, jumping right into operations without any mention of the program's history, and that's just fine. The only potential omission is a reference to OXCART preparations for missions over Cuba, but that's more of a nitpick than a true drawback, as those missions were, after all, never flown.

From RAINBOW to GUSTO: Stealth and the Design of the Lockheed Blackbird, Paul A. Suhler, 2009 This represents the single most fascinating book yet published on the Blackbird family. Suhler takes the reader through the various designs which led to the final A-12, including competing designs from Convair and proposed successors. Most of the usual technical aspects of the programs are glossed over or simply ignored, and with very good reason. For the first time, a book has been written focusing primarily on the program's efforts to defeat Soviet radar systems. This is definitely a must-read for any Blackbird enthusiast, or anyone interested in low RCS aircraft design.

Lockheed Blackbird Family: Photo Scrapbook, Tony Landis, 2010 This is exactly what it sounds like, a 126 page picture book featuring the Blackbird family. Don't expect a rehashing of the Blackbird's development, that's not the point here, and the actual text is very sparse. There are a number of amusing anecdotes in some of the captions, but the main focus is simply the images of the Blackbirds. There are a ton of images that have not been published before, and most of the book is presented in glorious full color. The highlights are images of two A-12s in formation flight, and a D-21 RCS model depicting a very early shape far removed from what was actually built. Most of the images depict the actual aircraft, with very few detail shots, although there are numerous new drawings of sensor systems and other items included as well. This book serves as an ideal, updated complement to Jim Goodall's SR-71 Blackbird Walk Around from 2003.

OTHER REFERENCES

There are, of course, other excellent Blackbird references to consider apart from books. Wings/Airpower magazine did a four-part piece, each focusing on a different Blackbird variant, a few years ago that was a great source of photographs and interesting bits of information. The Red Star volume on Soviet and Russian UAVs features a section on the Soviet D-21 clone, the Tupolev Voron, which makes for very interesting reading. And there is always the CIA's FOIA internet page, to see what the latest round of declassified documents brings to the OXCART historical knowledge base.

MAIN ERRORS

Two errors seem to propagate themselves among Blackbird books with relative regularity. These are not merely examples of honest educated guesswork refuted by the declassification of information, but rather more blatant errors that have apparently stuck around thanks to their persistence over time often despite the declassification of accurate information. Firstly, the AIM-47 missile carried by the F-12 was not armed with a nuclear warhead. A 0.25 kiloton warhead was investigated early on, but dropped when more accurate homing systems made the need for a nuclear warhead unnecessary. The history of the AIM-47 can be found in brief here (hey, who wrote that?). Secondly, the probes extending forward from the leading edges of the D-21's wings were not associated with the D-21B modification. While captive carry articles seen on M-21 60-6940 did not feature these probes, at least one D-21 launched from the back of M-21 60-6941 did feature them. This can be seen in a video depicting M-21 launch operations, including the fatal accident which destroyed 60-6941. The video is available online here. Look at screenshot M21_009 and the leading edge probes are clearly visible.

FUN ITEMS

Books are great, but a serious Blackbird fan can branch out into all sorts of fun territory. Many people like to collect patches, squadron and aircraft memorabilia, and the like. This is all well and good, and certainly enjoyable, but there are two items which are seriously recommended.

The first is a Century Wings diecast display model of the SR-71A, depicting the famous Ichi Ban Blackbird. Details and photos of this very large and very well detailed model can be seen here. It is over a foot in length, and looks very serious sitting on display among a diecast aircraft collection. Good luck, though, as they have sold out from the manufacturer and can only be obtained through a retailer who has them in stock!

The second item is another diecast aircraft. This one isn't as massive or detailed as the Century Wings Blackbird, but I personally find it to be far more amusing. Plus, and you all should appreciate this after my last example, you can usually find one for just a few dollars. Back in the early 80's you could find the Dyna Flites diecast airplane toys in stores. Pretty simple, usually around four inches long, little metal wheels for undercarriage. Well, check out the image below:
Cut-back chines, short tail...that's a YF-12A! If you can find one of these (I've got three...two from decades ago and a third from EBay), they are pretty unique and well worth it.

Of course, if you're seriously hardcore, you can always buy a piece of certified Blackbird titanium!

CONCLUSION

The source material available on the Blackbird family is increasing with each passing year, and it is fascinating to note how each new publication seems to shed new light on a previously unknown aspect of the aircraft's development or operational use. Until the OXCART, KEDLOCK, TAGBOARD, and SENIOR CROWN files are totally declassified, we likely will not know the complete history of an aviation icon. But it sure is fun to wade through the knowledge that the aforementioned authors have already pieced together for our benefit.

If you want to know where these aircraft are currently located so you can view one for yourself, check out the article here.

New Blackbird Reading

INTRODUCTION

One of the most interesting and researched topics in aviation history is the Lockheed Blackbird family of aircraft. Recently, three new books have been released, taking advantage of newly declassified information to shed new light on some of the more sinister aspects of these aircraft. A fourth book, a technical history of the program, has also been released, but has not yet arrived and will not be included in this review.

NEW BOOKS

Archangel: CIA's Supersonic A-12 Reconnaissance Aircraft - David Robarge
Written by the CIA's chief historian in 2007 and published for public release in 2008, this is an interesting reference on CIA OXCART operations. Available online here, Robarge does a credible job providing a concise look at the aircraft, the technology involved, and the operational history of the BLACK SHIELD program. The only thing lost in transferring Robarge's work to print is, amusingly, photographic resolution: the full color images found on the CIA website are reproduced in black and white in the printed work. Given that none of the images are previously unreleased, this is not a significant drawback. Where the printed work scores is in its inclusion of a number of declassified documents in its appendices. Kelly Johnson's OXCART history of 1968 is included, as well as a declassified OXCART Fact Sheet shedding light on numerous ECM systems carried by the aircraft. A reference list of every OXCART-related document held in the CIA's FOIO archives is also provided to make any researcher's job that much easier. While the two aforementioned documents are available at the CIA's FOIA archives, and the bulk of the text at the link provided above, Robarge's work is still an interesting reference work on one of the CIA's most advanced projects. Plus, how funny is it that he had to write the history without using the words "Groom Lake" or "Area 51"? Whether in print or online, this is a great read for Blackbird enthusiasts.

The Archangel and the OXCART - Jeanette Remak and Joseph Ventolo
Remak and Ventolo have teamed up in the past with 2002's A-12 Blackbird Declassified, at the time the most complete reference source for the CIA's OXCART program. Their current OXCART book is basically a thoroughly updated rehash of the older work, which given the amount of newly declassified reference material available in the intervening six years between publications is definitely a good thing. There is a wealth of interesting data to be mined from the book's 284 pages, more than double the pagecount of the previous "edition", including data on subjects such as anti-radar systems, ECM gear, and various support efforts aiding the OXCART test program. The problem here is in the execution. The book has been very poorly edited, and is full of typographical errors, particularly in the later chapters. Any serious Blackbird enthusiast would do well to still give this work a chance, however, as the value of the new material included outweighs the negative aspects of the book's formatting errors.

Lockheed SR-71 Operations in the Far East - Paul F. Crickmore
Paul F. Crickmore has made a name for himself among Blackbird enthusiasts for being one of the busiest authors, publishing numerous works on the aircraft since the 1980s. Every time a new wealth of information is uncovered or declassified, you can bet that Crickmore will have something new on the shelves in short order. In this case, he has written a volume in the Osprey Publishing Combat Aircraft series, this being number 76. This book basically details half of the Blackbird's operational career, covering OXCART and SR-71 operations out of Kadena AB in Japan, with a forthcoming volume slated to detail SR-71 operations out of RAF Mildenhall and the United States. It is important to note that this book is not an aircraft history, but rather focuses on the actual operational sorties themselves: the targets, the routes flown, and the interesting occurrences that took place on operational reconnaissance missions. While not as expansive as his last major Blackbird work, Lockheed Blackbird: Beyond the Secret Missions (2004), this is a must-read for anyone interested in Cold War era reconnaissance and intelligence gathering. As an added bonus, the obligatory color photographs, line drawings, and color profiles that are typical of Combat Aircraft series volumes are also included.

CONCLUSION

The Lockheed Blackbird family has fascinated aviation buffs for more than forty years, ever since LBJ revealed the USAF's YF-12A to the public under the "A-11" moniker. These three reference works indicate that the complete story of this remarkable family of aircraft may not be written for some time, as more and more information is declassified with the passage of time. Until the complete story is written, we can only rely on authors such as those listed above to piece together one of the most interesting stories of aviation history.

Blackbirds In Imagery

INTRODUCTION

One of the few aircraft to capture the attention of serious aviation buffs, casual fans, historians, and everyone else who has held it in their vision if only for a second is the Lockheed Blackbird, alternatively known to its pilots as the Sled. Born out of a requirement for a faster, higher-flying, more survivable replacement for the CIA's U-2, the Blackbird has become an aviation legend. In the spirit of the holidays, this article will detail the locations of Blackbird survivors and depict the locations of those visible in Google Earth. It's Sledding, Google Earth style!

THE BLACKBIRD

The Blackbird, also known as the Sled, the Habu, the Beast, and the Titanium Goose in its various incarnations, was created to fulfill a CIA requirement for a successor to the U-2. As the U-2 flew deep into the USSR on intelligence gathering sorties, advances in Soviet air defenses were threatening to make the CIA's original high flyer obsolete. Something more survivable was needed, and the result was the Lockheed A-12, designed for high speed and high altitude overflight of denied teritory. As it would turn out, the shootdown of Francis Gary Powers on the first day of May, 1960, ended manned overflight of the USSR. Seemingly an aircraft without a mission, the A-12 evolved into one of the mainstays of USAF Cold War intelligence gathering, the SR-71A, and had a productive intelligence gathering career in its own right.

OXCART

Out of 13 A-12s built for the CIA, only 8 remain. Two of these airframes, Articles 128 and 132, are currently on display indoors at the Central Intelligence Agency and Battleship Memorial Park in Mobile, Alabama, respectively. The rest of the surviving OXCARTs are on display outdoors and can be seen clearly in Google Earth imagery.

The first prototype of the A-12 family, Article 121, can be seen on display at Blackbird Airpark in Palmdale, California, in company with SR-71A Article 2024 and a D-21 drone:

The second A-12, also employed as a flight test airframe and the A-12 used for pole tests of the aircraft's radar cross section, is now on display at the USS Intrepid Sea, Air, and Space museum in New York City. This is the only Blackbird to be displayed on a carrier deck, and doubled as a tee box for Will Smith in the movie I Am Legend.

An image of the USS Intrepid in 2002 can be seen below, followed by an image from 2007 while the carrier was docked at Staten Island undergoing refitting and refurbishment.


A photograph of Article 122 on the deck of the USS Intrepid can be seen below:

Article 124, the fourth A-12 airframe and the only two-seat trainer, is on display at the California Science Center in Los Angeles. This aircraft, designated AT-12, was nicknamed Titanium Goose and never received the overall black paint scheme found on most other A-12s later in their flying careers.

Article 127 is on display at the Marshall Space Flight Center in Hutsville, Alabama. This aircraft is one of three OXCARTs to perform operational reconnaissance sorties out of Kadena AB, Japan. Amusingly, at one point Article 127 featured the characteristic yellow NASA fin stripe on its vertical tail surfaces. Suffice it to say that NASA never operated an A-12, the existance of which remained classified into the 1980's!

Article 128 was previously displayed at the Minnesota ANG Museum in Minneapolis before being removed for display at the CIA. An image of the aircraft on display outdoors in Minnesota is provided below.

Article 130 is on display in San Diego at the San Diego Aerospace Museum.

Article 131, the other surviving A-12 to have performed operational reconnaissance sorties (06932, the third aircraft, was lost during a training flight), is currently on display at the Birmingham Museum of Flight in Birmingham, Alabama. With three A-12s on display, Alabama currently possesses more than a third of the surviving OXCART fleet!

KEDLOCK

While the A-12 program was progressing, Lockheed realized that the airframe might be suitable for tasks other than reconnaissance. Project KEDLOCK produced an interceptor variant for the USAF, with three prototypes being constructed. The YF-12A prototypes were arguably the most advanced interceptors of their era, featuring long-range pulse-doppler AN/ASG-18 radar sets, and carrying three XAIM-47A air to air missiles.

Three YF-12As were constructed by modifying three A-12 airframes on the production line. These were aircraft 60-6934, 60-6935, and 60-6936, referred to as Articles 1001, 1002, and 1003 respectively. The first and third prototypes were written off in accidents, leaving Article 1002 as the sole survivor of the type. After a career as a flight test aircraft with NASA following the cancellation of the USAF F-12 program, Article 1002 was retired to the USAF Museum at Wright-Patterson AFB in Dayton, Ohio, where it resides to this day. The aircraft is currently situated in the R&D Hangar at the museum's annex facility.

The following photograph depicts the USAF Museum's YF-12A on display:

TAGBOARD

With the cancellation of manned overflights over Soviet territory, Lockheed began developing ideas for continuing a reconnaissance mission over these territories. The result was the M-21, a two-seat version of the A-12 specially configured to carry and launch a D-21 drone mounted above the rear fuselage. Despite being able to claim status as the world's fastest biplane, the M-21/D-21 combination ultimately proved to be unsuccessful, with the D-21 being modified for launch from two specially outfitted B-52H carriers under the SENIOR BOWL program. The two A-12s modified into M-21 standard were Articles 134 and 135.

06941 was lost during the fourth launch attempt of a D-21 drone, an accident which can be seen here. This video is very interesting from a historical standpoint. Apart from depicting a Mach 3 collision between two formerly classified intelligence gathering platforms, the video tears down one of the assumptions made about the D-21. It had been believed due to photographic evidence available that the leading edge probes seen on operational D-21Bs carried by the B-52H launch platforms had been added as part of the D-21B program. This can be seen to be completely untrue, as the D-21 launched from the back of 06941 possesses these same leading edge probes.

The surviving M-21 resides indoors at the Seattle Museum of Flight, complete with a mounted D-21.

A photograph of a D-21 on display at the USAF Museum can be seen below:

SENIOR CROWN

The SR-71A evolved out of the CIA's A-12 to provide the USAF with a twin-seat strategic reconnaissance aircraft capable of carrying multiple sensor fits to gather complex photographic and electronic intelligence. Operational SR-71As were based at Beale AFB in California. Not only did the SR-71A replace the CIA's A-12 at the Kadena AB operating location, but it served at RAF Mildenhall in England, gathering intelligence on Soviet and Warsaw Pact activity in Europe. Mildenhall-based Blackbirds also conducted reconnaissance over Libya in support of Operation ELDORADO CANYON, to cite a specific example of non-Communist directed operations.

19 SR-71s remain out of a total of 31 built, not including the technologically amusing SR-71C. This includes the remaining SR-71B, one of two built for pilot training. 11 SR-71s are displayed indoors, including the surviving SR-71B and SR-71C examples. These include Articles 2002, 2007 (SR-71B), 2009, 2012, 2013, 2015, 2022, 2023, 2027, and 2000 (SR-71C). Article 2013 is unique in that it is the only Blackbird on display outside the United States, residing at the Imperial War Museum in Duxford, England. The other aircraft displayed indoors reside at the following locations:

Article 2002: Pima Air Museum, Tuscon, Arizona
Article 2007: Kalamazoo Air Zoo, Battle Creek Airport, Michigan
Article 2009: Warner Robins Museum of Aviation, Warner Robins AFB, Georgia
Article 2012: Kansas Cosmosphere, Hutchinson, Kansas

Article 2006 was employed almost exclusively by Lockheed for flight test work supporting USAF SR-71 operations. It operated out of Palmdale, California and is currently on display at the Air Force Flight Test Center Museum at Edwards AFB, California, and can be seen in the image below:

Article 2010 was used between 1975 and 1976 to test the Big Tail modification, featuring an extended tail assembly housing various sensor fits. The aircraft was retired from service following the Big Tail test program and can currently be seen on display at the USAF Armament Museum at Eglin AFB, Florida, complete with Big Tail assembly. An image of the aircraft on display is provided below. Note that the extended tail fitting can clearly be seen.

Article 2011 is on display at the Castle Air Museum at Castle AFB, California.

Article 2014 is on display at Beale AFB, California, in company with a D-21 drone. The aircraft is mounted on a replica of one of the patches worn by SR-71 crewmembers.

Article 2018 is on display at Barksdale AFB, Louisiana but is not currently visible in Google Earth imagery. It is, however, visible in Microsoft Virtual Earth, as seen below:

Article 2019 is on display at the Virginia Aviation Museum, Richmond, Virginia.

Article 2024 can be seen on display at Blackbird Airpark as mentioned previously.

Article 2026 is on display at the March Field Air Museum, March AFB, California.

Article 2030 is on display at Heritage Field, Lackland AFB, Texas.

Article 2031 is on display at the NASA Dryden Flight Research Center, Edwards AFB, California.

RELATED AIRCRAFT

Three aircraft formerly involved with the Blackbird program in some capacity still exist today, and one can be seen in overhead imagery. The two B-52Hs modified to support D-21B drone launches, 60-0036 and 61-0021, are still in use. The former aircraft serves at the USAF flight test facility at Edwards AFB, while the latter is in operational service at Barksdale AFB, Louisiana. A B-58 Hustler was modified to serve as a test aircraft for the AN/ASG-18 and AIM-47 combination used by the YF-12A. This aircraft was originally supporting the F-108 program, the aircraft for which the weapon systems originated before it was cancelled. This B-58, 55-665, was nicknamed Snoopy due to its long, drooping radome fitted for the AN/ASG-18. It currently resides on the range at Edwards AFB as a photographic target and can be seen in the image below:

CONCLUSION

I hope everyone has enjoyed this "holiday-themed" aviation topic. The Blackbird is one of the most interesting aircraft to ever exist, and more information on CIA A-12 operations is declassified each year, ensuring that the complete story has yet to be written. In the meantime, take note of the locations of these high performance aircraft, and take the time to go see one close to you if possible. You won't be disappointed!
