Those without military knowledge are not aware that ICBM and SLBM are missile systems that share the same technology. if apply the technology of ICBM to a submarine, it becomes SLBM. The ICBM and SLBM are technically exactly the same. ICBM greatest weakness is that missiles are fired from fixed missile silos. This means that if the missile silo is destroyed, there is no means of responding. SLBM, on the other hand, has similar accuracy to ICBM, has the same range as ICBM, And is a more covert means of attacking targets than ICBM. For this reason, the UK, which is currently a representative maritime country, has scrapped ICBM and operates only SLBM separately.
