The Sopwith Triplane was a follow-up to the highly successful 80hp Pup that was widely liked by the young pilots of the Royal Flying Corps (RFC) and Royal Naval Air Service (RNAS). The Triplane prototype was powered by a 110hp Clerget rotary. The prototype was quickly accepted and sent to the front for trials with A Squadron of the RNAS. A Squadron took the new Tripe into combat as soon as it arrived in France. A second Triplane powered by the 130hp Clerget was sent to France in August of 1916. This new highly maneuverable aircraft was an instant hit with the RNAS pilots who had a chance to fly it in combat. Although similar to the Pup, the Triplane fuselage was redesigned for the larger 110hp & 130hp rotary engines. The wingspan was the same as the Pup, but the narrow chord wings allowed better visibility for the pilots. It was more maneuverable than the Pup and had a quicker rate of climb.

Through their intelligence gathering operations in the Spring of 1942, the Soviet Military Command became aware that Hitler and the Wehrmacht were planning a forthcoming summer offensive. In order to disrupt the Germans, Stalin ordered Soviet forces, under the command of Marshal Timoshenko, to prepare and launch a campaign to disrupt German plans. The area chosen was the Kharkov sector, the intent being to encircle and destroy the German Sixth Army. However, unbeknownst to the Soviets, the Germans were planning their own offensive in the Kharkov area, code named Operation Fridericus. What started as a promising Soviet push ended up with a German rout of Soviet forces, and one of the Red Army’s biggest defeats of the Second World War.

The Squadron In Action series was started in 1971. This series covers the development, testing, and production of aircraft, armored vehicles, and ships. The focus of this book is on the C-17 Globemaster III.

In 1968, the USAF was looking for a replacement of the C-130. They wanted a medium transport that could carry 67 percent more cargo with STOL capabilities. Two companies stepped up with two designs – Boeing with the YC-14 and McDonnell Douglas with the YC-15. McDonnell Douglas was eventually awarded the contract and thus the C-17A was born.
