I have not done any proper write-up on this new starship of mine yet, but she was commissioned in 2374. I have a lot of notes and ideas scribbled down, but I will eventually flesh her out properly, describing what she is for, but essentially, she is a long range explorer, with minimum staff and lots of internal space used for science and exploration as well as resources to sustain her away from port for many years. She is a later iteration of the old Chayenne class starships, which also had four nacelles, only this latter engine assembly is far more efficient and calibrated to sustain a very solid warp field for long durations of time.
Here are the other ships of the same class:
IROQUOIS-CLASS
USS Iroquois NX-78494, Prototype
USS Mohawk NCC-78495
USS Seneca NCC-78496
USS Oneida NCC-78497
USS Cayuga NCC-78498
USS Onondaga NCC-78499
