Iridium initially launched on a wide variety of launch vehicles, too. Wikipedia says the first generation launched on four vehicles: U.S. Delta II, Russia’s Proton-K/DM2 and /strong>Rokot/Briz-KM, and China’s Long March 2C/SD.

The point is a good one, though. Most satellites and probes are designed to be able to handle the conditions and fairing envelopes of three or so launch vehicles, in case a backup is necessary, but not many get to fly on very many different vehicles. Even each generation of GPS may not have flown on five different vehicles. Some of the GPS antennas were sensitive information, so it probably only launched on U.S. vehicles, limiting the number of different vehicles for each generation of satellite.

Antares 1xx series
Atlas V
Antares 2xx series
Falcon 9
Antares 3xx series

That is kind of cool Mayb only GPS comes close to that record of different launch vehicles?

Falcon 9, Atlas V, Atlas II what else? I cannot be bothered to look it up.
