In context

Use the Astute class for neutral comparisons of modern nuclear-powered attack-submarine scale. Its 97 m length, speed field above 30 knots, complement range of 98 to 109, and nuclear propulsion distinguish it from smaller non-nuclear AIP boats; mission capability should be compared separately from these physical and operating facts.
