Intel science destroyer

The intel science destroyer was a Federation intel starship, a science vessel-destroyer hybrid class in Section 31 and Starfleet service in the 2250s and 2410s decades. Vessels of the class were rated tier 6. 

History and specifications
In 2257, a vessel of this type, the NCIA-93, was used by Captain Leland of Section 31. His crewmates included $𝜇$, former Emperor of the Terran Empire. 

The rogue artificial intelligence corrupted the body of Kamran Gant and used it to turn the NI-1101 into a trap for Commander Michael Burnham and Lieutenant Spock. 

A week following the eruption of TL-9139 that forced Starfleet to abandon Yard 39 and its fleet of ships there in 2259, a Section 31 intel science destroyer attempted to recover these assets but was left abandoned.

In 2410, the double agent Lieutenant Michelle Rautert secretly investigated Yard 39, apparently unbeknownst to her official superiors at Starfleet Intelligence and unofficial allies at Section 31. However, Franklin Drake dispatched Agent Jamok to apprehend Rautert aboard the vessel. Rautert incapacitated Jamok and advised her SI contact Lieutenant Commander Kyla VanZyl of USS Voyager of her findings. (SS STO (Triple Cross))
