<strong>Retiring</strong> <strong>Trident</strong><br />
Assessment:<br />

B61-12 launched at 45kft, egress height of 100ft, initial<br />
nose down angle of 55 – 75 degrees, egress speed 700<br />
knots;<br />
::<br />
B61-12 launched at 45kft, level turn, egress height of 45kft,<br />
egress speed 1026 knots.<br />
::<br />
There are a range of credible attack profiles that utilise the F-35C’s<br />
stealth characteristics to delay detection until shortly before weapon<br />
release, allowing egress at medium or low level.<br />
::<br />
The B61-12 RCS is unknown, and thus it is unknown how easy it<br />
would be to intercept by the defences. For heavily defended targets,<br />
the obvious riposte is to significantly increase the number of B61-12s<br />
simultaneously in flight – 80 bombs plus 40 receding aircraft targets<br />
on a range of attack profiles and egress headings would make the<br />
defenders’ task considerably more complicated.<br />
::<br />
If priority were (correctly) given to the incoming bombs over shooting<br />
down the departing aircraft, then two 48N6E or 9M96E2 missiles<br />
should be fired against each incoming bomb. Assuming an 85% probability<br />
of kill (Pk) per missile, each double targeted bomb has a 2.25%<br />
chance of survival. If 160 SAMs are launched, this implies a near-certainty<br />
than one and high probably that two B61-12s would reach the<br />
target.<br />
::<br />
85% Pk is a reasonable worst-case scenario for the attackers, and it<br />
assumes that the system is working optimally, and that there are in<br />
fact sufficient missiles available to double-target each bomb. If this is<br />
not the case, or if the Pk falls because of, e.g., difficulties in tracking<br />
the low RCS, then the number of weapons reaching the target rises<br />
rapidly. For instance, if all 80 were targeted by a single missile with an<br />
85% Pk, then 12 of the 80 B61-12s would make it to the target.<br />
