Plus Trip in the Mirror Universe episodes says that the warp nacelles on the TOS Defiant are stunningly large and impressive and he wonders how many warp coils they have. The 289-meter Enterprise does have considerably bigger nacelles than the NX-01, but the 442-meter Enterprise makes Mirror Trip's utterance that much more believable.
That's not how it looked in STE. Non canon. The Connie was closer to 300 meters. Just below it. Yup.
