Deployable nose for an underwater vehicle

A deployable nose is used on an underwater vehicle to provide a shorter length when in a retracted position and to provide a reduced drag when in the deployed position. The deployable nose includes a plurality of nose sections and a deployment mechanism that moves the plurality of nose sections from the retracted position to the deployed position. The nose sections include a base nose section attached at the end of the underwater vehicle, an outer nose section having a rounded contour, and one or more intermediate nose sections between the base nose section and outer nose section. In the retracted position, the outer nose section and one or more intermediate nose sections are retracted generally within the base nose section. In the deployed position, the outer nose section and intermediate nose sections extend outwardly from the base nose section and interlock proximate the edges of the nose sections to form the deployed nose.
