Scholte-class missile corvette
From Halopedia, the Halo wiki
Fitted with a good mix of cannon and missile batteries, backed by a comprehensive sensor system, the Scholte was classified—at the time of introduction into the CMA Navy's fleet—as a state-of-the-art frigate. As larger ships entered service both its classification and stature diminished, but it remained a vessel that could be counted upon to punch far above its tonnage class.
Now known as one of the main ship classes that UNSC Navy recruits operate as part of their training deployments, the Scholte-class has an unenviable reputation as being reliable, heavily-armed, and rarely utilized in any fleet engagements until the final months of the Covenant War due to its slow boost speed and limited slipspace capabilities.
The Scholte-class' appearance originated as a part of design exploration exercise for UNSC ships, done as a collaboration between the narrative and concept teams at 343 Industries, during the development of Halo Infinite and the 2022 edition of the Halo Encyclopedia. This was the result of a fortiutous alignment of interests, which allowed them to leverage the ideas generated for multiple purposes; the narrative team wished to further flesh out the UNSC fleet, while the concept team needed to craft ship designs for Infinite, which would ultimately culminate in the Mulsanne-class light frigate seen in-game.
