The SB-1 is big af. I guess some clever photographs sort of diguise its dimensions, even when parked next to the UH-60. Landing footprint, okay, not too much more H-60. Defiant is as big around as a CH-46 or Mi-17. Look how much taller and wider it is, and how much heavier it seems. That would be a major factor if it's going to be on a carrier. As there's all that space required for the midpoint to support the two sets of stacked rotors, it's got to weigh twice as much.
2x as tall as UH60 and V280
UH-60 and SB-1
larger than an Mi-17?
