The OH-58C is an upgrade of the OH-58A. It has a more powerful engine, as well as flat panel windscreen glass and improved avionics. The flat panel glass is installed to reduce distortion while using night vision goggles. Like all OH-58s, the OH-58C has been flown in a wide variety of missions, including Air Cavalry AeroScout, Attack Battalion Scout, Liaison, Logistics, Etc. It can be equipped to fire the Stinger air-to-air missile. While the vast majority of the OH-58Cs built were flown by the US Army, a small number were loaned to the US Navy, and flown mostly at the US Navy Test Pilot School.
