If we had the Zephyr, then fielding multiples might be a necessity.
If the Kronos gets more dock modules and cargo with no stats change, then we'll probably make at least two to three, with each one have a specific purpose - and combat being the secondary of its intended roles.
If nothing happens, and the stats stay the same, then the Kronos will be there, and we might have two for base sieging in coro, but they would never have wide spread use.
