- HYPERSONIC FIGHTERS AND HIGH-POWER LASERS 13/02/96

-
- HYPERSONIC FIGHTERS and high-power lasers are among the futuristic
- next-generation weapons envisioned for use by the US armed forces in a report
- released by the US Air Force Scientific Advisory Board (SAB).
-
- The 2,000-page study, New World Vistas, foresees the use of precision sensors
- and hypersonic missiles against surface-to-air missiles (SAMs), and the
- development of a hypersonic fighter aircraft equipped with high-power laser
- beams capable of destroying air and land targets.
-
- The report also discusses an all weather airlift capable of precision airdrops
- to an accuracy of 10m (30ft), an "uninhabited" combat air vehicle (UCAV) and
- the need for a follow-on global-positioning system with 10mm accuracy. Gene
- McCall, chairman of the SAB, says that satellite- and aircraft-borne sensors
- should be able to pinpoint SAM sites anywhere in the world for attack by
- hypersonic weapons launched from as far away as 320km (l75nm) and able to
- strike the site a minute later.
-
- "We can make the operation of SAM sites the world's most dangerous occupation,"
- says McCall.
-
- He says that it is not far-fetched to believe that high-power microwave pulses
- could one day be used to knock out SAM sites. Hughes Missile Systems was
- recently awarded a $7 million USAF contract to study whether such non-lethal
- pulses can be used for suppression of-enemy-air-defences missions.
-
- Meanwhile, the Advanced Research Projects Agency is studying the feasibility of
- flying unmanned, semi-autonomous, tactical aircraft in combat. The term
- "uninhabited" combat aircraft is used to distinguish it from today's
- "unpiloted" and "unmanned" cruise missiles and futuristic reconnaissance
- vehicles such as the Lockheed Martin/Boeing Tier III Minus Darkstar.
-
- The UCAVs would be extremely high-performance special-mission aircraft. They
- would use aircraft and weapons technologies which cannot be used in an aircraft
- which contains a human.
-
- For example, shape and function would not be constrained by a cockpit and
- ejection seat required for a human body. Higher-G manoeuvres and more effective
- stealth will also be possible, says McCall.
-
- USAF Secretary Sheila Widnall says that the report will be used to set the pace
- for limited research and-development investments and predict future weapons
- systems. "This study is not going to sit on the shelf and gather dust. We have
- already set aside funds for some of these promising new areas of research. We
- will integrate New World Vistas into the mainstream of air force planning,"
- adds Widnall.
