§ 127. Emergency and extraordinary expenses

(a) Subject to the limitations of subsection (c), and within the limitation of appropriations made for the purpose, the Secretary of Defense, the Inspector General of the Department of Defense, and the Secretary of a military department within his department, may provide for any emergency or extraordinary expense which cannot be anticipated or classified. When it is so provided in such an appropriation, the funds may be spent on approval or authority of the Secretary concerned or the Inspector General for any purpose he determines to be proper, and such a determination is final and conclusive upon the accounting officers of the United States. The Secretary concerned or the Inspector General may certify the amount of any such expenditure authorized by him that he considers advisable not to specify, and his certificate is sufficient voucher for the expenditure of that amount.
(b) The authority conferred by this section may be delegated by the Secretary of Defense to any person in the Department of Defense, by the Inspector General to any person in the Office of the Inspector General, or by the Secretary of a military department to any person within his department, with or without the authority to make successive re­delegations.
(c)
(1) Funds may not be obligated or expended in an amount in excess of $500,000 under the authority of subsection (a) or (b) until the Secretary of Defense has notified the Committee on Armed Services and the Committee on Appropriations of the Senate and the Committee on Armed Services and the Committee on Appropriations of the House of Representatives of the intent to obligate or expend the funds, and—
(A) in the case of an obligation or expenditure in excess of $1,000,000, 15 days have elapsed since the date of the notification; or
(B) in the case of an obligation or expenditure in excess of $500,000, but not in excess of $1,000,000, 5 days have elapsed since the date of the notification.
(2) Subparagraph (A) or (B) of paragraph (1) shall not apply to an obligation or expenditure of funds otherwise covered by such subparagraph if the Secretary of Defense determines that the national security objectives of the United States will be compromised by the application of the subparagraph to the obligation or expenditure. If the Secretary makes a determination with respect to an obligation or expenditure under the preceding sentence, the Secretary shall immediately notify the committees referred to in paragraph (1) that such obligation or expenditure is necessary and provide any relevant information (in classified form, if necessary) jointly to the chairman and ranking minority member (or their designees) of such committees.
(3) A notification under paragraph (1) and information referred to in paragraph (2) shall include the amount to be obligated or expended, as the case may be, and the purpose of the obligation or expenditure.
(d) Annual Report.— Not later than December 1 each year, the Secretary of Defense shall submit to the congressional defense committees a report on expenditures during the preceding fiscal year under subsections (a) and (b).
