Okay, having read, ruminated, and digested, here's my review of this work.
TL: DR :- Buy this bookazine!!
Those of us who have bought the author's previous self-published works will be familiar with his narrative style, and especially his superb CAD drawings. This volume takes both of these to the next level.
With 130 pages and 118 different titled drawings, this volume offers a concise, yet comprehensive, history of the Lockheed A-12, YF-12, and SR-71 series of aircraft, along with their predecessor projects 'Suntan' and 'Archangel', as well as the competing 'FISH / Kingfish' projects from Convair, as well as the bonkers-looking 'Hazel', and B-58 Hustler derivatives from the same company.
The CIA operated single seat A-12 is described, as well as the 'Titanium Goose' trainer version along with proposed armed and carrier based variants.
Early proposals for A-12 derived interceptors are described, as are the built YF-12 airframes, in addition to the proposed production - standard 'F-12B' referred to as the AF-112D. Also mentioned is the FB-12 armed variant, along with the various armament schemes proposed. Also described here are the Republic XF-103, North American F-108, and the various Convair B-58 derived interceptors.
The D-21 drone is also discussed, along with it's M-21 carrier, along with the B-52 launched, rocket boosted version.
Next to be described is the production SR-71A and it's trainer version, together with it's proposed B-71, SR-71(Bx) and SR-71I armed variants,
in addition to the YF-12C experimental aircraft used by NASA and the proposed modifications to enable it to carry externally mounted payloads.
A final set of entries describe the use of the SR-71 to carry and launch various hypersonic test articles, and also the LASRE aerospike engine testbed.
There are no photographs in this work, although with the highly detailed drawing, none are really necessary.
Gripes? Only a few. To the reviewer's mind, the stock on which this work is printed is a little flimsy, although, as a bookazine rather than a true book, this can be tolerated. In order to fit the drawings to the space available on the page, some of them have odd scales, which can make it difficult sometimes to compare drawings, although wherever possible, comparable drawing ARE to the same scale. On this subject, the reviewer noticed a couple of drawings marked with the wrong scale, in particular on page 16 and page 108. Further, on page 100, the AF-112D drawing, there appears to be an error with the port chine, at the aircraft's nose.
Overall, this is an excellent reference work on the A-12, YF-12, and SR-71 series of aircraft, and while those requiring a highly detailed narrative account of the history of these aircraft may need to go elsewhere, as a' go-to' reference, 'Origins and Evolution: SR-71 Blackbird' is an excellent addition to the enthusiast's and modeller's library. Recommended.
