[X] Blister Deflector and Ventral Nacelles (+20,000 Tons)
I like this, both because it preserves internal space, and also because aesthetically ventral nacelles would look closer to making a Miranda or Defiant look-alike. For the preserved space, I'm hoping that we can make this useful as a high speed courier or interceptor - ie., even aside from patrolling to prevent breaches of the borders by Klingon Birds of Prey or other light combatants, it can also run around shuttling VIPs or time sensitive cargo that needs to get somewhere faster than a Cygnus can manage (with the Type 3 nacelles, we're going to have a Maximum Cruise a full .2 warp factors higher than the Cygnus or Sagarmatha, and an efficient cruise on par with the Cygnus).
