Lockheed Martin THAAD Extended Range (THAAD ER)

Описание: Lockheed Martin is pushing for funding for the development of an ER version of the THAAD to counter maturing threats posed by hypersonic glide vehicles adversaries may employ, namely the Chinese WU-14, to penetrate the gap between low and high-altitude missile defenses. The company performed static fire trials of a prototype modified THAAD second booster in 2006 and continued to self-fund the project until 2008. The current 14.5 in (37 cm)-diameter single-stage booster design would be expanded to a 21 in (53 cm) first stage for greater range with a second "kick stage" to close the distance to the target and provide improved velocity at burnout and more lateral movement during an engagement. Although the kill vehicle would not need a redesign, the ground-based launcher would have to be modified with a decreased interceptor capacity from eight to five. Currently, THAAD-ER is an industry concept and not a program of record, but Lockheed believes the Missile Defense Agency will show interest because of the threats under development by potential adversaries. If funding for the THAAD-ER began in 2018, a fielded product could be produced in 2022. Although the system could provide some capability against a rudimentary hypersonic threat, the Pentagon is researching other technologies like directed energy weapons and railguns to be optimal solutions. Therefore, the THAAD-ER would be an interim measure to counter the emerging threat until laser and railgun systems capable of performing missile defense come online, expected in the mid to late-2020s
