For the DF-5C, it has a huge warhead with D~1.4m L~3.2m, which is almost impossible to find a similar counterpart among American RV.
If it truly belongs to the FOBS system as speculated by Chinese military bloggers, a more noteworthy issue is that the tail of the reentry vehicle lacks nozzles similar to those of its Soviet counterparts. Ofc, this might be because this RV is merely for display purposes as mock up and not a genuine RV.
Through a simple comparison of dimensions, if it is a traditional modern RV (means it no longer uses a metal shell similar to the DF-5A but switches to a carbon shell), and its yield could reach 9-10 Mt. If it is a warhead with PBV and reentry capabilities, similar to FOBS, the yield might be between 3-5 Mt.
