; (B) a space-based sensor layer consisting of two separate constellations, one for tracking and discriminating ballistic missiles and one for tracking dim ballistic targets and hypersonic missiles, would enable the United States to use interceptor inventory more efficiently and effectively to counter a broad array of threats; and (C) space-based sensors are absolutely critical for the real threat that we see in front of us, the hypersonic threat . (8) Admiral James Syring, a former Director of the Missile Defense Agency, has stated, From a missile defense perspective, we have to develop a future operational space layer. Given where the threat is going with hypersonics and more ICBMs and so forth this persistent tracking and discrimination capability from space is a must. . (9) The Department of Defense’s 2019 Missile Defense Review states that— (A) the exploitation of space provides a missile defense posture that is more effective, resilient, and adaptable to known and unanticipated threats; (B) space-based sensors, for example, can monitor, detect, and track missile launches from locations almost anywhere on the globe—they enjoy a measure of flexibility of movement that is unimpeded by the constraints that geographic limitations impose on terrestrial sensors; and (C) unlike land-based sensors, space sensors do not require basing rights or agreements with foreign states enabling them to be placed where necessary to achieve the ideal viewing geometry for launch detection, missile tracking, threat discrimination, and intercept detection/kill assessment of missile threats to the United States homeland, our forces abroad, and to our allies and partners. (b) Sense of Congress It is the sense of Congress that— (1) the two most recently enacted National Defense Authorization Acts have expressed support for a space-based missile defense sensor program
