§ 4231. Major systems: determination of quantity
for low-rate initial production
(a) DETERMINATION OF QUANTITIES TO BE PRO-
CURED FOR LOW-RATE INITIAL PRODUCTION.—(1) In
the course of the development of a major sys-
tem, the determination of what quantity of arti-
cles of that system should be procured for low-
rate initial production (including the quantity
to be procured for preproduction verification ar-
ticles) shall be made—
(A) when the milestone B decision with re-
spect to that system is made; and
(B) by the official of the Department of De-
fense who makes that decision.
(2) In this section, the term ‘‘milestone B deci-
sion’’ means the decision to approve the system
development and demonstration of a major sys-
tem by the official of the Department of Defense
designated to have the authority to make that
decision.
(3) Any increase from a quantity determined
under paragraph (1) may only be made with the
approval of the official making the determina-
tion.
(4) The quantity of articles of a major system
that may be procured for low-rate initial pro-
duction may not be less than one operationally
configured production unit unless another quan-
tity is established at the milestone B decision.
(5) The Secretary of Defense shall include a
statement of the quantity determined under
paragraph (1) in the first SAR submitted with
respect to the program concerned after that
quantity is determined. If the quantity exceeds
10 percent of the total number of articles to be
produced, as determined at the milestone B deci-
sion with respect to that system, the Secretary
shall include in the statement the reasons for
such quantity. For purposes of this paragraph,
the term ‘‘SAR’’ means a Selected Acquisition
Report submitted under section 4351 of this title.
(b) LOW-RATE INITIAL PRODUCTION OF WEAPON
SYSTEMS.—Except as provided in subsection (c),
low-rate initial production with respect to a new
system is production of the system in the min-
imum quantity necessary—
(1) to provide production-configured or rep-
resentative articles for operational tests pur-
suant to section 4171 of this title;
(2) to establish an initial production base for
the system; and
(3) to permit an orderly increase in the pro-
duction rate for the system sufficient to lead
to full-rate production upon the successful
completion of operational testing.
(c) LOW-RATE INITIAL PRODUCTION
OF NAVAL
VESSEL AND SATELLITE PROGRAMS.—With respect
to naval vessel programs and military satellite
programs, low-rate initial production is produc-
tion of items at the minimum quantity and rate

that (1) preserves the mobilization production
base for that system, and (2) is feasible, as deter-
mined pursuant to regulations prescribed by the
