In 1944, the Army issued requirements for a jet-propelled medium bomber which eventually spawned four aircraft. These were the North American B-45 (see Air Force Legends 224), Convair XB-46 (see Air Force Legends 221), Boeing B-47, and the Martin XB-48 the sudject of this book. Specifications were somewhat general and called for an 80,000 to 200,000 lb aircraft with a 45,000 ft ceiling, range of 3,000 miles and a maximum speed of 550 mph. The Martin designwas a three-place, straight wing, six-jet, high wing, all metal medium bomber. The unique landing gear developed by Martin consisted of dual wheel main gear located in tandem with outrigger single type wing gear. This gear arrangement allowed for a huge continuance bomb bay with quick acting doors capable of carrying a 22,000 lb "Grand Slam" bomb. The other unique feature of the airplane was instalation of the six J35 engines. Each engine (three on a wing) had its own squarish nacelle seperated with by-pass ducts framed by a thin airfoil plate across the bottom of the three engines mounted under each wing. Two aircraft were produced and were tested at the Naval air Test Center, NAS Patuxent River, MD, about 70 miles from Martin's New River plant before being accepted by the Air Force. The XB-48 was not accepted for production, those contracts going to the B-45 and B-47. The second XB-48 finished its life as a landing pilot training plane for future B-47 pilot's.

Taken as an accumulation of photographs with solid captioning this an excellent monograph and certainly worth the money if you’re detailing one of the two models available. And as mentioned the captioning is solid. (Except for a minor glitch on page 12. The order given on the lower row is reversed.) Overall, for some reason I disappointed by the amount of text that was available. To be fair, the text that is present while sparse is reasonably informative. But you get let down by its paucity. For example, the issue with nacelles gets a short paragraph with no discussions about attempts to rectify it. Considering Stan Piet from the Martin Museum Archives is listed as a contributor, that’s somewhat surprising.
As casual observation, it was interesting to see how fast Martin made initial progress, from contract acceptance on the 29th of December while the Battle of the Bulge was being fought to the start of mock-up inspection on April 19th little more than two weeks before VE day was impressive, even by the standards of the day.
While one can sing high praises of the monograph as a modeling reference and viewed as akin to a walkaround volume this is a solid if somewhat overpriced purchase. As a history of the aircraft? It’s a bit disappointing when stacked up against other AF Legends offerings.
Strongly Recommended for modelers, non-modelers approach with caution. (
