India is now working on Agni-6 for its MIRVs
technologies that certainly suggest Delhi's power projection aspirations in the broader region.
The missile is intended to resist missile defenses by using hypersonic warheads, called MIRVs
The US has as many as 10 separate bombs in its MIRVs
Because of the larger amount of nuclear material consumed by MRVs and MIRVs
, single warhead missiles are more attractive for nations with less advanced technology.
Not all the sUASs in the offensive swarm need to be deadly, as the parallels with MIRVs
extend beyond a simple numerical advantage.
They warned incessantly of the "window of vulnerability" that would open in the early 1980s when the Soviets could target their MIRVs
against the considerably smaller number of US land-based missiles.
Because they put a premium on striking first, MIRVs
were seen as inherently destabilising and were limited in the SALT II treaty, the second major strategic arms limitation treaty signed in 1979.
Both countries are in the process of modernizing their forces, and, ominously, by 2020 many of the systems are expected to carry nuclear-tipped MIRVs
and sophisticated decoys.
It further added that China is developing countermeasures to missile defense, such as multiple independent re-entry vehicles, or MIRVs
, which if deployed in an ICBM makes the missile much harder to intercept.
One method, as both Mansoor Ahmed (from the Department of Defence and Strategic Studies at Quaid-e-Azam University) and Usman Shabbir (of the Pakistan Military Consortium think tank) suggest, would be to employ submarine-launched, nuclear-tipped cruise missiles, along with land-based Shaheen II ballistic missiles equipped with MIRVs
(multiple independently targetable reentry vehicles).
Treaties were reached with limits on launchers and aircraft and limited deployments of antiballis-tic missiles, but there were still potentially destabilizing "improvements" such as "multiple independent reentry vehicles," called MIRVs
, that allowed one missile to carry many warheads.
So far, China has not deployed MIRVs
on its current nuclear arsenal but has shown the capability of adding up to three warheads on its new DF-31 truck mobile intercontinental ballistic missile.
