depends on more than just the size of one's military forces; factors like decision making and response times, the ability to penetrate enemy active and passive defenses, and the effectiveness of defensive systems mean that even a stockpile of weapons several times larger than necessary to destroy the enemy does not ensure overkill.
Improvements in the US ability to track nuclear-armed submarines contribute to this danger, since that raises the tantalising possibility of destroying the enemy's second-strike capability
in a surprise assault.
Technically the best mode of second-strike capability
is submarine launched ballistic missile, which neither India nor Pakistan have deployed as yet, Cheema said.
This second-strike capability
defines the baseline for US deterrence capability, but it is not the only option of which US forces are capable.
37) According to Chinese experts, a few main reasons lurking behind Chinese concerns were the traditionally small size of its nuclear arsenal and that arsenal's questionable second-strike capability
These 'K' class cruise missiles are predominantly significant for India's nuclear deterrent arsenal because they provide India with a much more idyllic and invulnerable second-strike capability
thus, transforming the balance of power in India's favour in South Asia.
China is close to having a secure nuclear second-strike capability
, which heightens the importance of the conventional balance.
Israel would require new submarines and ballistic launch facilities to ensure second-strike capability
4) Since Israel is considered to have more than 100 nuclear weapons, how credible is the argument that Iran might attack Israel without first itself acquiring a significant nuclear arsenal, including a survivable second-strike capability
, a prospect that is at least some years away?
According to recent reports (which emerged from German sources connected to the recent expansion of the underwater force through the acquisition of a sixth Dolphin-class submarine equipped with air-independent propulsion system) on the Israeli capability to maintain a nuclear second-strike capability
with cruise missiles on board its Type 800 Dolphin conventional-propulsion submarine force, the new Strategic Israeli Command has sub-launched long-range weapon systems tipped with both nuclear and conventional warheads.
One of the key issues in considering this question is assessing each side's second-strike capability
, about which an enormous amount of ink was spilled over the course of the Cold War.
There is no second-strike capability
and if the pistol fails to fire it is necessary to work the slide to re-cock the hammer and chamber a new round.
