USS Pastak

The USS Pastak (NCV-474438-G) was a Federation timeship in service to Starfleet in the 29th century. The ship's commanding officer is Captain Walker. 

In the year 2409 of an alternate timeline, the temporally displaced USS Enterprise (NCC-1701-C) attempted to escape from a Tholian base in the Azure Nebula. The Pastak arrived to defend the Enterprise against Tholian vessels and single-handedly destroyed a dreadnought. Following the defeat of the Tholian flottilla, the Pastak ensured the Enterprise's return through the temporal rift to the Narendra system in 2344.
