In an alternate timeline, at least two Y class ships were part of the fleet which took the remnants of Humanity to Ceti Alpha V after the Earth was destroyed. 
The Y class ships began to retire from service in 2210, and the last vessel completed its final mission in 2243.

Mayweather also states that a ship like this might be hauling "fifty kilotons of dilithium ore". This is something of a YATI - the Enterprise used lithium crystals rather than dilithium in early season 1 of TOS, so technically ships of the Enterprise era should use lithium or something more primitive. Fifty kilotons would presumably represent the ship's maximum payload.
The size of the ship is just an estimate, and there are no really good comparison shots in the episode so it's very hard to judge correctly.
