## Part Ii.  Definitions

Unless otherwise noted, these terms and definitions are for the purpose of this issuance.

CUA.  An assessment showing the relationship between the capabilities provided by the system and the impact that operating that system has on basing, time phased force deployment data, manpower, maintenance, available fuel, and other secondary impacts on the ability of a Combatant Command or Military Department to carry out its mission.

IAMD.  Defined in Joint Publication 3-01.
MDS.  An evolving, integrated, and interoperable system, comprising multiple missile defense elements that provide a capability to intercept ballistic missiles in flight and also hypersonic missiles in flight.  Hypersonic missiles include hypersonic boost-glide vehicle capabilities and conventional prompt strike capabilities, in accordance with Section 1687 of Public Law 114-328, as well as hypersonic cruise missiles.

MDS element.  An established program of record that is a component of the MDS.
TLRD.  A document defining a tailored set of performance and functionality attributes or parameters unique for each MDS element that quantifies warfighter capability requirements.  For example, the TLRD for terrestrial radars may include parameters quantifying the requirements for discrimination, raid capacity, track accuracy, peak and average power, system reliability, and others.  The TLRD is derived from required MDS capabilities directed from the following: United States Strategic Command development requirements from the Warfighter Involvement Process (currently the Prioritized Capabilities List), inputs from the Joint Requirements Oversight Council or Joint Urgent Operational Need/Joint Emergent Operational Need processes, Presidential mandates and congressional direction.  The TLRD will be described in the MDS Systems Engineering Plan.
