SKYRANGER OA-X2 LIGHT-ATTACK AIRCRAFT 27 July 2017 Puma Aero Marines Skyranger OA-X2 is to perform light attack, armed reconnaissance, counter-insurgency (COIN) and military flight trainer, available at a very low cost compared to similar aircraft. The Skyranger is a light attack aircraft that carries a big punch; she is built with the ability to mount the M-61 Vulcan 20 mm cannon on the center line under the chin, which is capable of an extremely high rate of fire. This low cost, extremely reliable aircraft has great performance and pilot visibility for counter-insurgency missions. This design is perfect for operational requirements for conducting counter-insurgency missions at hot high altitudes, flying low through mountain valleys and over the jungle. The fuselage is based on the Puma Aero Marine Boss UAV-VTOL. The fuselage has a welded aluminum frame and Kevlar carbon fiber with Core-Cell hand lay-up vacuum infused skin and panels. The tail booms and vertical stabilizer are Kevlar carbon fiber with Core-Cell, which is vacuum infused. The wings and horizontal stabilizer are of aluminum. All for very low maintenance and a long life. History In addition to fulfilling the requirements of a much-needed military trainer, in 2009 the United States Air Force Light Attack/Armed Reconnaissance program was born. Because of the requirement for a new, very close air support aircraft which was suited for combating gorilla and insurgent forces in urban environments being faced in post 2003 Iraq, Afghanistan, Africa and South America. The close air support role was carried out by several different aircraft, including the A-10 Thunderbolt II (Warthog), the F-16 Fighting Falcon, AF-18 Hornets and the F-15 Strike Eagle. While all of these aircraft are capable of close air support, only the A-10 was purpose built for the type of support needed by ground troops in a "low intensity conflict," or COIN (COunterINsurgency), operation. The United State Air Force is just starting to evaluate the Light Attack/Armed Reconnaissance aircraft and initially requires 300 of this aircraft.
