Preview: On January 9, 2017, Pakistan’s Inter-Services Public Relations (ISPR) announced that the country had successfully carried out the first-ever flight test of a nuclear-capable, submarine-launched cruise missile (SLCM)—the Babur-3, a variant of the Babur-2 ground-launched cruise missile.With the introduction of the Babur-3, Pakistan seems headed toward adding a sea leg in the coming decade to complement a nuclear force structure that previously relied solely on land-based missiles and aircraft-delivered weapons.
