The Secretary of Defense shall submit to Congress each calendar year, not later than 45 days after the President submits the budget to Congress under section 1105 of title 31, budget justification documents regarding development and procurement schedules for each weapon system for which fund authorization is required by section 114(a) of this title, and for which any funds for procurement are requested in that budget. The documents shall include data on operational testing and evaluation for each weapon system for which funds for procurement are requested (other than funds requested only for the procurement of units for operational testing and evaluation, or long lead-time items, or both). A weapon system shall also be included in the annual documents required under this subsection in each year thereafter until procurement of that system has been completed or terminated, or the Secretary of Defense certifies, in writing, that such inclusion would not serve any useful purpose and gives his reasons therefor.

In the case of any weapon system for which procurement funds have not been previously requested and for which funds are first requested by the President in any fiscal year after the Budget for that fiscal year has been submitted to Congress, the same documentation requirements shall be applicable to that system in the same manner and to the same extent as if funds had been requested for that system in that budget.
