History
Launched in 2410, the Deleth was one of three prototype starships developed by the Alpha Quadrant Alliance based on the Federation's tier 1 Miranda-class light cruiser/frigate. Its counterpart in Federation Starfleet was the Reliant-class advanced light cruiser, and the QeHpu'-class advanced light battlecruiser in the Klingon Empire. These classes were the first to be equipped with the potential energy entangler console. (STO video game: Escalation website: The Advanced Light Cruiser Bundle)
