OPS 3762, also known as FTV-2355, was an American reconnaissance satellite which was launched in 1964. It was the first radar imaging satellite to be launched, and the only Quill spacecraft to fly. Its mission was to demonstrate radar imaging techniques for future missions. However, the programme was cancelled before any more satellites were launched.
