For a true first strike platform, you need something that can carry high accurate MIRV/ This means bigger warheads (nuclear warhead size and yield don't scale quite as linearly as conventional ones, but there is a link). Which means terminal guidance. Also countermeasures. And a powerful post boost vehicle (PBV) with space for multiple warheads, as well as sufficient on-board propellant to release warheads on an optimal trajectory.Why?
What existing systems cannot achieve this?
Especially when it is change in messaging and reiterating posture rather than anything different to capability?
All this requires a heavier payload, a large PBV and MIRV versus a simple warhead mounting and RV.
When we talk about missile range, what you are actually saying for payload mass x a missile has range y (trajectory also affects it but we will ignore for now). Adjusting x makes y greater and vice versa.
As a very rough rule of thumb (@JamD could explain better), halving the payload mass increases range by 40%.
So the same missiile which carrying 6 heavy MIRV on a bulky warhead PBV which can hit say 4000km, will have ICBM range with a single light warhead and no PBV.
