Toss bombing, Sverdlov cruisers, and the nuclear threshold

Did the Royal Navy plan to use toss bombing with nuclear weapons against Sverdlov-class cruisers?

The technique was available, but conventional weapons were preferred and a nuclear attack was treated as a last-resort escalation.

The discussion describes a lofted or toss-bombing technique that allowed an aircraft to release a weapon while turning away from the target. Such profiles could be planned against Sverdlov-class cruisers with nuclear or conventional weapons. The Royal Navy preferred to use other weapons first rather than treat a nuclear strike as the routine answer to a surface group. Nuclear employment would mark a later phase of a wider war, so the delivery technique is separated from the political decision to cross the escalation threshold.
