10 U.S.C. § 3501 (ARMED FORCES)
§ 3501. Multiyear contracts: acquisition of property
(a) In General.—
To the extent that funds are otherwise available for obligation, the head of an agency may enter into multiyear contracts for the purchase of property whenever the head of that agency finds each of the following:
(1) That the use of such a contract will result in—
(A) significant savings of the total anticipated costs of carrying out the program through annual contracts; or
(B) necessary defense industrial base stability not otherwise achievable through annual contracts.
(2) That the minimum need for the property to be purchased is expected to remain substantially unchanged during the contemplated contract period in terms of production rate, procurement rate, and total quantities.
(3) That there is a reasonable expectation that throughout the contemplated contract period the head of the agency will request funding for the contract at the level required to avoid contract cancellation.
(4) That there is a stable design for the property to be acquired and that the technical risks associated with such property are not excessive.
(5) That the estimates of both the cost of the contract and the anticipated cost avoidance through the use of a multiyear contract are realistic.
(6) In the case of a purchase by the Department of Defense, that the use of such a contract will promote the national security of the United States.
(7) In the case of a contract in an amount equal to or greater than $500,000,000, that the conditions required by subparagraphs (C) through (F) of subsection (i)(3) will be met, in accordance with the Secretary’s certification and determination under such subsection, by such contract.
(b) Regulations.—
(1) Each official named in paragraph (2) shall prescribe acquisition regulations for the agency or agencies under the jurisdiction of such official to promote the use of multiyear contracting as authorized by subsection (a) in a manner that will allow the most efficient use of multiyear contracting.
(2)
(A) The Secretary of Defense shall prescribe the regulations applicable to the Department of Defense.
(B) The Secretary of Homeland Security shall prescribe the regulations applicable to the Coast Guard, except that the regulations prescribed by the Secretary of Defense shall apply to the Coast Guard when it is operating as a service in the Navy.
(C) The Administrator of the National Aeronautics and Space Administration shall prescribe the regulations applicable to the National Aeronautics and Space Administration.
(c) Contract Cancellations.—
The regulations may provide for cancellation provisions in multiyear contracts to the extent that such provisions are necessary and in the best interests of the United States. The cancellation provisions may include consideration of both recurring and nonrecurring costs of the contractor associated with the production of the items to be delivered under the contract.
(d) Participation by Subcontractors, Vendors, and Suppliers.—
In order to broaden the defense industrial base, the regulations shall provide that, to the extent practicable—
(1) multiyear contracting under subsection (a) shall be used in such a manner as to seek, retain, and promote the use under such contracts of companies that are subcontractors, vendors, or suppliers; and
(2) upon accrual of any payment or other benefit under such a multiyear contract to any subcontractor, vendor, or supplier company participating in such contract, such payment or benefit shall be delivered to such company in the most expeditious manner practicable.
(e) Protection of Existing Authority.—
The regulations shall provide that, to the extent practicable, the administration of this section, and of the regulations prescribed under this section, shall not be carried out in a manner to preclude or curtail the existing ability of an agency—
(1) to provide for competition in the production of items to be delivered under such a contract; or
(2) to provide for termination of a prime contract the performance of which is deficient with respect to cost, quality, or schedule.
(f) Cancellation or Termination for Insufficient Funding.—
In the event funds are not made available for the continuation of a contract made under this section into a subsequent fiscal year, the contract shall be canceled or terminated. The costs of cancellation or termination may be paid from—
(1) appropriations originally available for the performance of the contract concerned;
(2) appropriations currently available for procurement of the type of property concerned, and not otherwise obligated; or
(3) funds appropriated for those payments.
(g) Contract Cancellation Ceilings Exceeding $100,000,000.—
(1) Before any contract described in subsection (a) that contains a clause setting forth a cancellation ceiling in excess of $100,000,000 may be awarded, the head of the agency concerned shall give written notification of the proposed contract and of the proposed cancellation ceiling for that contract to the congressional defense committees, and such contract may not then be awarded until the end of a period of 30 days beginning on the date of such notification.
(2) In the case of a contract described in subsection (a) with a cancellation ceiling described in paragraph (1), if the budget for the contract does not include proposed funding for the costs of contract cancellation up to the cancellation ceiling established in the contract, the head of the agency concerned shall, as part of the certification required by subsection (i)(1)(A),1 give written notification to the congressional defense committees of—
(A) the cancellation ceiling amounts planned for each program year in the proposed multiyear procurement contract, together with the reasons for the amounts planned;
(B) the extent to which costs of contract cancellation are not included in the budget for the contract; and
(C) a financial risk assessment of not including budgeting for costs of contract cancellation.
(h) Defense Acquisitions of Weapon Systems.—
In the case of the Department of Defense, the authority under subsection (a) includes authority to enter into the following multiyear contracts in accordance with this section:
(1) A multiyear contract for the purchase of a weapon system, items and services associated with a weapon system, and logistics support for a weapon system.
(2) A multiyear contract for advance procurement of components, parts, and materials necessary to the manufacture of a weapon system, including a multiyear contract for such advance procurement that is entered into in order to achieve economic-lot purchases and more efficient production rates.
(i) Defense Acquisitions Specifically Authorized by Law.—
(1) In the case of the Department of Defense, a multiyear contract in an amount equal to or greater than $500,000,000 may not be entered into under this section unless the contract is specifically authorized by law in an Act other than an appropriations Act.
(2) In submitting a request for a specific authorization by law to carry out a defense acquisition program using multiyear contract authority under this section, the Secretary of Defense shall include in the request a report containing preliminary findings of the agency head required in paragraphs (1) through (6) of subsection (a), together with the basis for such findings.
(3) A multiyear contract may not be entered into under this section for a defense acquisition program that has been specifically authorized by law to be carried out using multiyear contract authority unless the Secretary of Defense certifies in writing, not later than 30 days before entry into the contract, that each of the following conditions is satisfied:
(A) The Secretary has determined that each of the requirements in paragraphs (1) through (6) of subsection (a) will be met by such contract and has provided the basis for such determination to the congressional defense committees.
(B) The Secretary’s determination under subparagraph (A) was made after completion of a cost analysis conducted on the basis of section 3226(b) of this title, and the analysis supports the determination.
(C) The system being acquired pursuant to such contract has not been determined to have experienced cost growth in excess of the critical cost growth threshold pursuant to section 4374 of this title within 5 years prior to the date the Secretary anticipates such contract (or a contract for advance procurement entered into consistent with the authorization for such contract) will be awarded.
(D) A sufficient number of end items of the system being acquired under such contract have been delivered at or within the most current estimates of the program acquisition unit cost or procurement unit cost for such system to determine that current estimates of such unit costs are realistic.
(E) During the fiscal year in which such contract is to be awarded, sufficient funds will be available to perform the contract in such fiscal year, and the future-years defense program for such fiscal year will include the funding required to execute the program without cancellation.
(F) The contract is a fixed price type contract.
(G) The proposed multiyear contract provides for production at not less than minimum economic rates given the existing tooling and facilities.
(4) If for any fiscal year a multiyear contract to be entered into under this section is authorized by law for a particular procurement program and that authorization is subject to certain conditions established by law (including a condition as to cost savings to be achieved under the multiyear contract in comparison to specified other contracts) and if it appears (after negotiations with contractors) that such savings cannot be achieved, but that significant savings could nevertheless be achieved through the use of a multiyear contract rather than specified other contracts, the President may submit to Congress a request for relief from the specified cost savings that must be achieved through multiyear contracting for that program. Any such request by the President shall include details about the request for a multiyear contract, including details about the negotiated contract terms and conditions.
(5)
(A) The Secretary may obligate funds for procurement of an end item under a multiyear contract for the purchase of property only for procurement of a complete and usable end item.
(B) The Secretary may obligate funds appropriated for any fiscal year for advance procurement under a contract for the purchase of property only for the procurement of those long-lead items necessary in order to meet a planned delivery schedule for complete major end items that are programmed under the contract to be acquired with funds appropriated for a subsequent fiscal year (including an economic order quantity of such long-lead items when authorized by law).
(6) The Secretary may make the certification under paragraph (3) notwithstanding the fact that one or more of the conditions of such certification are not met, if the Secretary determines that, due to exceptional circumstances, proceeding with a multiyear contract under this section is in the best interest of the Department of Defense and the Secretary provides the basis for such determination with the certification.
(7) The Secretary may not delegate the authority to make the certification under paragraph (3) or the determination under paragraph (6) to an official below the level of Under Secretary of Defense for Acquisition and Sustainment.
(j) Defense Contract Options for Varying Quantities.—
The Secretary of Defense may instruct the Secretary of the military department concerned to incorporate into a proposed multiyear contract negotiated priced options for varying the quantities of end items to be procured over the period of the contract.
(k) Multiyear Contract Defined.—
For the purposes of this section, a multiyear contract is a contract for the purchase of property for more than one, but not more than five, program years. Such a contract may provide that performance under the contract during the second and subsequent years of the contract is contingent upon the appropriation of funds and (if it does so provide) may provide for a cancellation payment to be made to the contractor if such appropriations are not made.
(l) Various Additional Requirements With Respect to Multiyear Defense Contracts.—
