Except US launchers are very outdated. US relies on numbers for nuclear deterrence and had no intention of using nukes while they had conventional superiority. That conventional superiority doesn't exist anywhere near "superiority", anywhere near even the 2nd island chain. China since 2010s have relied on far superior launchers while only maintaining around 500 warheads to guarantee overkill of US + EU (since EU have militarily threatened China in the past and still continue to threaten involvement). China's economy and industry has already curbstomped the US to death around 2010. It is only western cope and self delusion that keeps this illusion of US economic might alive. US economy died slowly since 1970 and died completely around a decade ago. It's just a zombie now and every US administration has tried various tactics to make the zombie into a living being again. US has only military strength left. That is it. Nada. AI industry is a joke that produces useless slop. Money printer still goes brrrr and middle class will continue eroding until gone. Various events in coming years will only make this reality obvious to every moron and cool aid drinker. US is as brainwashed as North Koreans and Wahabis.
Outside of SSBN, Chinese launchers are much more hidden, mobile, or out of reach compared to US launchers. US silo based launchers use low tier masking and no hardening. Chinese silo based launchers are similar. This is where the similarities end. US has not (that we know of!) thousand km tunnel systems under mountains that can withstand direct xx MT warhead detonations. Many of China's ICBMs in those underground Great Walls make Iran's take on it look like an afterthought. China started building these underground Great Walls since the 1970s.
US also doesn't employ much container (rail based) and any TEL based ICBMs that we know of. SSBN is their go to. China has no strategic ranged stealth bomber or resilient and plentiful SSBN based nuclear deterrence which is why it focused on far superior delivery technology.
Now there are numbers of warheads (around 1000) and still building like there is no tomorrow (to ensure there can be no tomorrow for the West if the morons in Washington decide so). SSBN proliferation with Type 094 numbering over 6 units and with JL-3 able to hit anywhere in the US and EU from port. Type 096 componentry and techntested since mass production lines have finished some time ago, first 096 construction starting last year.
All this means there need to be more warheads to arm all the new SSBNs, new ICBMs with various delivery systems, and upcoming H-20. Silo and TEL ICBM numbers have also rocketed up. People here were saying 500 warheads is enough. How could that have been possible when China was building new DF-5 generation and JL-3 like sausages. This is just the ICBM and SLBM based component, now we have FOBS/ Intercontinental ranged HGVs that need warheads, long range cruise missiles (sub launched HCM and ship launched HGV) that could use nuclear warheads and when H-20 hits the tarmac, that's going to need warheads. 500 already wasn't enough for the existing numbers of DF-31, DF-41, JL-2, and DF-5 in 2015. China has approx 3x number of just DF-31 DF-41 and JL-2/3 (vs JL-2) numbers in 2025. You would already need approx 1500 warheads to feed those delivery systems from profileration of intercontinental ranged delivery systems that you've built up over the decades.
Now there are planned dozens of 096 that require ~12x3 of warheads each assuming 3 warheads MaRV per JL-3 for MT yields. Far more for smaller KT yields.
