Command-Integrated Missile Defense, the service acquisi-
tion executives (as defined in section 101 of title 10, United 
States Code), and the commanders of the combatant com-
mands, develop operationally relevant metrics for evalu-
ating the effectiveness of the integrated Ballistic Missile De-
fense System (BMDS) and its components and elements 
against operationally realistic ballistic missile attacks into 
areas defended by United States combatant commands. 
(b) INCORPORATION OF METRICS INTO ANNUAL RE-
PORTS.—Beginning in February 2019, the Director of the 
Missile Defense Agency shall incorporate the metrics devel-
oped under subsection (a) into the annual reports of the 
Director to the congressional defense committees, including 
an assessment of progress against such metrics on the acqui-
sition baseline of the Missile Defense Agency. 
(c) LIMITATION.—Of the funds authorized to be appro-
priated for fiscal year 2019 by this Act and available for 
the Command and Control, Battle Management and Com-
munications (C2BMC) program, not more than 50 percent 
may be obligated or expended until the Director develops 
the metrics required by subsection (a).

SEC. 1657. SENSE OF THE SENATE ON ACCELERATION OF 
MISSILE DEFENSE CAPABILITIES. 
(a) SENSE OF THE SENATE.—It is the sense of the Sen-
ate that the Missile Defense Agency should— 
(1) accelerate the fielding, if technically feasible, 
of the planned additional 20 ground-based intercep-
tors with Redesigned Kill Vehicles (RKV) at Missile 
Field 4 at Fort Greely, Alaska, and to mate the Rede-
signed Kill Vehicles with the newest booster tech-
nology; 
(2) weigh the rapid growth in missile and nu-
clear threats against the cost and risk of accelerating 
the Redesigned Kill Vehicle and the Multi-Object Kill 
Vehicle development and deployment; 
(3) ensure, prior to its operational deployment, 
that the Redesigned Kill Vehicle has demonstrated the 
ability to accomplish its intended mission through a 
successful, operationally realistic flight test;
802 
† HR 5515 PAP
(4) rapidly develop and deploy a persistent, 
space-based sensor architecture to ensure our missile 
defenses are more effective against ballistic missile 
threats and more responsive to new and emergent 
threats from hypersonic and cruise missiles; 
(5) pursue innovative concepts for existing tech-
nologies, such as a missile defense role for the F–35 
aircraft; and 
(6) invest in advanced technologies, such as 
boost-phase warning, tracking, and intercept.

(1) IN GENERAL.—Not later than 180 days after 
the date of the enactment of this Act, the Director of 
the Missile Defense Agency shall submit to the con-
gressional defense committees a report on ways the 
Missile Defense Agency can accelerate the construction

sile defense assets to counter and deter against cruise, 
short-to-medium-range ballistic, and hypersonic mis-
sile threats; 
(2) the United States should continue to rapidly 
work toward the interoperability of all United States 
missile defense systems for a more effective layered de-
fense; and 
(3) the United States Army should increase its 
attention, focus, and resources developing an inte-
grated air-and-missile defense architecture to protect

SEC. 1660A. SENSE OF THE SENATE ON RESULTS OF TESTS 
CARRIED OUT BY MISSILE DEFENSE AGENCY. 
It is the sense of the Senate that— 
(1) tests carried out by the Missile Defense Agen-
cy, which do not achieve an intercept or the main ob-
jective, should not be considered failures; 
(2) the Missile Defense Agency—in an effort to 
deliver capabilities at the speed of relevance—should 
recognize the learning value of individual advance-
ments made by all test events, rather than viewing 
any total outcome as an indication of the reliability 
of entire missile defense systems; 
(3) the Missile Defense Agency should, as part of 
its test program, continue to build an independently 
accredited modeling and simulation element to better 
inform missile defense performance assessments and 
test criteria; and 
(4) the Missile Defense Agency should continue to 
pursue an increasingly rigorous testing regime, in co-
ordination with the Office of the Director, Oper-
ational Test and Evaluation, to more rapidly deliver 
capabilities to the warfighter as the threat evolves.
