The short range of the early SLBMs dictated basing and deployment locations. By the late 1960s the Polaris A-3 was deployed on all US SSBNs with a range of 4,600 kilometres (2,500 nmi), a great improvement on the 1,900 kilometres (1,000 nmi) range of Polaris A-1. The A-3 also had three warheads that landed in a pattern around a single target.
