That was what was wrong with most of the TOS and Tmp fan designs they did not have a traditional or any deflector dish. Maybe they had a different deflector system. That is why with the u.s.s ares that I created for star trek axanar the deflector is smaller but there none the less.
The Akyazi class is kind of a "23rd Century Defiant." It has the same concept as the Defiant - a very fast, hard-hitting and tough starship with minimal amenities and a short cruising range - rendered on technology of the era of the original-series Star Trek movies.
