Longsword Squadron Delta was part of the Longsword detachment aboard the UNSC Commonwealth in 2525.[1]

Service HistoryEdit

During the Battle of Chi Ceti, they were used as a decoy to distract a Covenant Raiding ship to launch a Shiva Warhead.[2] They were all incinerated when the Warhead exploded, unable to get into the shields of the Covenant ship in time.
