The term ‘non-strategic nuclear weapon’ (NSNW) includes nuclear warheads for all delivery systems such as gravity bombs for aircraft other than nuclear-capable heavy bombers, nuclear warheads for naval cruise missiles and torpedoes, and nuclear warheads for anti-ballistic missile (ABM) and air defence systems. The NSNWs term would also capture any nuclear warheads for surface-to-surface missiles with less-than-50 kilometres ranges, and nuclear artillery shells.
