APPENDIX 3A: ACATS 20
Table 1. Description and Decision Authority for ACAT I – III Programs, Continued.
5. An AIS is a system of computer hardware, computer software, data or telecommunications that performs functions such
as collecting, processing, storing, transmitting, and displaying information. Excluded are computer resources, both
hardware and software, that are: embedded as an integral part of a weapon or weapon system; used for highly sensitive
classified programs (as determined by the SecDef) or other highly sensitive information technology programs (as
determined by the DoD Chief Information Officer; or determined by the DAE or designee to be better overseen as a non-
AIS program (e.g., a program with a low ratio of research, development, testing, and evaluation funding to total program
acquisition costs or that requires significant hardware development). An AIS that breaches the dollar thresholds in Section
2302d of Title 10, U.S.C., as adjusted, is a “major system.”
b. ACAT IB Programs.
(1) Pursuant to Subsection (d) of Section 2430, of Title 10, U.S.C., the SAE of the
Military Department that is managing an MDAP reaching Milestone A after October 1, 2016 will
be the MDA for the MDAP unless, based on one or more exceptions in the statute, the SecDef
designates an alternate MDA. In accordance with DoDD 5135.02, the SecDef has delegated the
authority to designate an alternate MDA for an MDAP to the USD(A&S).
(2) At least annually, at submission of the Program Objective Memorandum, each SAE
will provide, in writing, sufficient information to allow the USD(A&S) to consider whether any
of the bases for designation of an alternate MDA as set forth in Section 2430(d) of Title 10,
U.S.C., apply. This information must be provided for all programs for which the Military
Department anticipates an MDD or a Milestone A decision (or later milestone decision if this
will be the program's first milestone) in the first year of the Program Objective Memorandum
FYDP and that are estimated to require eventual total expenditures of funds for all increments
that exceed the MDAP dollar value thresholds set in Section 2430 of Title 10, U.S.C., as adjusted
and specified in Table 1.
(3) Programs, for which the SAE is the MDA by operation of Section 2430 of Title 10,
U.S.C., will be designated within the DoD as ACAT IB programs to differentiate these programs
from ACAT ID programs, where the USD(A&S) is the MDA, or ACAT IC programs, where the
USD(A&S) as the DAE has delegated the DAE's decision authority to the SAE. Should the
USD(A&S) designate the DAE or other official as the alternate MDA the ACAT IB program
will be re-designated as ACAT ID.
(4) Pursuant to subparagraph (d)(3)(A) of Section 2430, of Title 10, U.S.C., for programs
for which the USD(A&S) has designated an alternate MDA, the Secretary of the Military
Department concerned, or designee, may request reversion of responsibility back to the SAE.
The USD(A&S) must make a decision with regard to the Military Department's request within
180 days after receiving the request. In the event the MDA for the program reverts back to the
SAE, either at the request of the Military Department or at the DAE's discretion, the program
would revert from its ACAT ID designation to an ACAT IB designation.
(5) SAEs managing ACAT IB programs must continue to comply with all statutes that
require information about an MDAP to be provided to OSD or the Office of the USD(A&S). For
example, Section 2432 of Title 10, U.S.C., requires the SecDef to submit Selected Acquisition
Reports (SARs) for MDAPs. For ACAT IB programs, the Military Departments must continue
