UNSC Pony Express

The UNSC Pony Express was a UNSC corvette. As of 2552, it was the fastest ship available to the UNSC.

During The Second Battle of Earth, the Pony Express was at Earth fighting the Covenant. After receiving a message from Dr. Halsey, Lord Hood planned on sending the Spartan-IIs to Onyx aboard the Pony Express, but they opted to instead capture a Covenant destroyer, the Bloodied Spirit, which was faster than even the Pony Express.

Trivia

 * Pony Express is a reference to the old mail system where riders would take fast horses from checkpoint to checkpoint, picking up mail and getting a new horse at each one.
