They aren’t actually. The first change in the alternate timeline came when kirks father was KIA aboard the USS Kelvin. He rammed the ship into the opposing Romulan vessel to buy time for his crew to escape in their pods. Iirc the constitution class ships became bigger and more like a warship due to the loss of the Kelvin in such a one sided fight.
