(b) The Secretary of the Navy, whenever the needs of the service require but at least once annually, shall compute the number of officers authorized under subsection (a) for each grade above lieutenant. The number so computed is the number of line officers on active duty, excluding officers carried as additional numbers in grade, prescribed for the grade concerned. However, if the Secretary determines at the time of making these computations that the number of officers required to meet the needs of the service in any grade above lieutenant is less than the prescribed number for that grade as computed, the lesser number becomes the prescribed number for the grade and the reduction may be applied as an increase in the prescribed number for any lower grade. (c) Of the numbers of officers prescribed for the grades of commander and lieutenant commander, as computed or determined under subsection (b), not more than the following percentages may be officers designated for limited d u t y: (1) Conmiander—3«%oo percent.
