The Datafile series returns to Italy with the latest title, this time focusing on the SIA SP.2 and SP.3. With nearly two dozen struts separating the wings and a framed twin-boom design, the SP.2 has a decidedly skeletal look to it that is rather appealing. First flown in 1916, the central nacelle underwent several changes as testing took place before finally moving to the vertical bow design seen on the production examples. In an effort to improve weight and maneuverability, a follow-on variant, the SP.3, was developed with a shorter wingspan. Still, the type had problems operationally, including control issues that led to limitations on its flying. Its slow speed and lack of maneuverability made it vulnerable to enemy fighters. Even basic operations caused problems, as ground debris stirred up by the landing gear impacted the pusher propeller, resulting in frequent propeller changes. These problems, coupled with delays in the introduction of the replacement aircraft, led to the severe decline in Italian reconnaissance in 1917.

As to be expected from a Datafile, this title tells the story of the SP.2 and SP.3 quite well. The author knows his subject well, and this translates into a text that is both easy to read and informative. In addition to describing the development of the type, the author also provides a richly detailed operational history, including its usage in home defense units and training schools. Illustrating the text are over 80 photos, many of which are quite interesting in terms of markings. The usual high quality scale drawings are included in the center, both in 1/72 and 1/48, with plenty of details and cross sections provided. For color reference, the back page has three profile illustrations that highlight some of the variations in markings and design.

Italian WWI subjects are fascinating, both in terms of design and markings, yet they often fall to the wayside in favor of the more common British, French, and German subjects. Thankfully, Albatros Publications is working to remedy that, and this latest title is very welcome indeed. My thanks to Albatros Publications for the review copy.
