1969-011A
The Intelsat III F-3 satellite was launched in Feb 1969 and became the Pacific satellite. However only a few months later one of two tunnel diode amplifiers malfunctioned, and the satellite was replaced as Pacific primary by the newly launched Intelsat III F-4. It was then moved to become Intelsat's first Indian Ocean region satellite. It was to remain over the Indian Ocean for a decade until it was finally decommissioned in Dec 1979.
