5 can actually defend the whole Armaland but in case of a massive strike more 3FF5 is needed. 3FF5, different from other ABMs, also serves to intercept high-altitude bombers such as B-52H, which can fly in the stratosphere. Such slow targets will be entirely unable to dodge the 3FF5 once it is launched. The 3FF5 had perfect accuracy of 0 cep and speeds up to 10 mach and thus will be able to defend against the fastest missile and MIRVs better than previous models. Also, the 3FF5 uses a kinetic warhead, which smashes the target instead of exploding on it, making it much safer as it will have less chance of exploding during transportation or when the vehicle is hit.
