On August 12, 2552 during the Battle of Viery, Grafton provided fire support for UNSC Army forces engaging in combat in the Viery Territory, accompanied by the frigate UNSC Saratoga. During the battle, Grafton was authorized to utilize its Magnetic Accelerator Cannon to destroy a Covenant structure codenamed "Spire One".[1]Grafton succeeded in destroying the installation. The CSO-class supercarrierLong Night of Solace, which had been hovering over the battle area which had been cloaking, revealed itself. With its cloaking shield gone, the supercarrier opened fire on Grafton with its ventral energy projector, destroying the frigate within less than a second, the beam ripping through the Titanium-A armor.[1]
The frigate is likely named after the city of Grafton, Australia.
The ship could also be named after the USS Grafton, a ship that was in service during WWII. It could also be named after the HMS Grafton, a ship that participated (and was destroyed) in Operation Dynamo.
During Tip of the Spear, Grafton's cannons fire in bursts of eight.
The infamous Scarab gun is said to be hidden on the Grafton and is accessible by using a glitch to get out of the spire's energy shield, but this is unconfirmed.
