SUPPORT 
INTEGRATED AIR AND MISSILE DEFENSE CAPABILITIES. 
(a) IN GENERAL.—Consistent with the memorandum of the 
Chairman of the Joint Chiefs of Staff of January 27, 2014, regarding 
joint integrated air and missile defense, the Vice Chairman of 
the Joint Chiefs of Staff shall oversee the development of warfighter 
requirements for persistent and survivable capabilities to detect, 
identify, determine the status, track, and support engagement of 
strategically important mobile or relocatable assets in all phases

employment of such assets, including through offensive actions 
against such assets prior to their use. 
(b) PURPOSE OF REQUIREMENTS.—The requirements developed 
pursuant to subsection (a) shall be used and updated, as appro-
priate, for the purpose of informing applicable acquisition programs

for the integrated operation of multiple systems, and, as appro-
priate, the development of requirements for capabilities to be 
acquired to achieve such integrated operations. 
(d) SENSE
OF CONGRESS.—It is the sense of Congress that 
new acquisition programs for applicable major systems or capabili-
ties, or for upgrades to existing systems, should not be undertaken
