Multiyear procurement (MYP) and block buy contracts (BBC) are special contracting mechanisms that Congress permits the Department of Defense (DOD) to use for a limited number of defense acquisition programs.

Compared to the standard or default approach of annual contracting, MYP and BBC have the potential for reducing weapon procurement costs by a few or several percent.

Under annual contracting, DOD uses one or more contracts for each year’s worth of procurement of a given kind of item.

Under MYP, DOD instead uses a single contract for two to five years’ worth of procurement of a given kind of item without having to exercise a contract option for each year after the first year.

DOD needs congressional approval for each use of MYP.

In practice, actual savings from using MYP rather than annual contracting can be difficult to observe or verify because of cost growth during the execution of the contract due to changes in the program independent of the use of MYP rather than annual contracting.

BBC is similar to MYP in that it permits DOD to use a single contract for more than one year’s worth of procurement of a given kind of item without having to exercise a contract option for each year after the first year.

BBC is also similar to MYP in that DOD needs congressional approval for each use of BBC.

However, BBC differs from MYP in the following ways:
-- There is no permanent statute governing the use of BBC.
-- There is no requirement that BBC be approved in both a DOD appropriations act and an act other than a DOD appropriations act.
-- Programs being considered for BBC do not need to meet any legal criteria to qualify for BBC, because there is no permanent statute governing the use of BBC that establishes such criteria.
-- A BBC contract can cover more than five years of planned procurements.
-- Economic order quantity (EOQ) authority—the authority to bring forward selected key components of the items to be procured under the contract and purchase the components in batch form during the first year or two of the contract—does not come automatically as part of BBC authority because there is no permanent statute governing the use of BBC that includes EOQ authority as an automatic feature.
-- BBC contracts are less likely to include cancellation penalties.
