- SECRET ADVANCED VEHICLES DEMONSTRATE TECHNOLOGIES FOR FUTURE MILITARY USE
- Advanced secret aircraft developed at highly classified government
- facilities in the Nevada desert over the last decade are demonstrating and
- validating new technologies for the U.S.'s future fighters, bombers and
- reconnaissance platforms.
- Although facilities in remote areas of the Southwest have been home to
- classified vehicles for decades, the number and sophistication of new
- aircraft appear to have increased sharply over the last 10 years, when
- substantial funding was made available for "deep black" projects.
- Vehicles now flying from these well-guarded sites include both manned
- and unmanned hypersonic-capable aircraft designed to perform strategic
- reconnaissance and other, less conventionally defined missions. The
- classified fleet also comprises a number of large-winged concept
- demonstrators that evolved into the Air Force's B-2 bomber and the Navy's
- A-12 next-generation attack aircraft. Several vehicles, though, appear to
- incorporate technologies that outstrip those now employed by engineers
- charged with developing more traditional, current-generation aircraft.
- A number of these aircraft have been seen and heard repeatedly by
- ground-based and airborne observers in the western U.S. over the last few
- years. Based on about 45 reports provided by people who have seen, heard or
- had access to the advanced aircraft, there now appear to be at least two -
- but probably more - distinct types of vehicles!
- * A triangular-shaped, *quiet* aircraft seen with a flight of Lockheed
- F-117A stealth fighters several times since the summer of 1989. This may be a
- demonstrator or prototype of the General Dynamics/McDonnell Douglas A-12.
- Navy officials recently noted that full-size test models will soon be
- "exposed to public view" during testing, suggesting that predecessors of the
- A-12 are already flying.
- * A high-speed aircraft characterized by a very loud, deep, rumbling
- roar reminiscent of heavy-lift rockets. When observed at medium altitude,
- this aircraft type often makes a pulsing sound and leaves a thick, segmented
- smoke trail or contrail. Lighting patterns indicate the aircraft is on the
- order of 100+ ft. long, but no reliable description of a planform has been
- reported to Aviation Week & Space Technology.
- * A high-altitude aircraft that crosses the night sky at extremely high
- speed. Normally, *no engine noise or sonic boom is heard*. The vehicle
- typically is observed as a single, *bright light* - sometimes pulsating -
- flying at speeds far exceeding other aircraft in the area, and at altitudes
- estimated to be above 50,000 ft. Such aircraft have been reported by both
- ground-based and airborne observers. This may be the same vehicle as the one
- characterized by a loud, pulsing noise when flying at lower altitude and
- slower speed...
- ...These primary types of "black" aircraft appear to employ relatively
- conventional propulsion systems, although more advanced than those available
- to the "white" world. In addition, there is substantial evidence that another
- family of craft exists that relies on *exotic propulsion and aerodynamic
- schemes not fully understood at this time*. Data pertaining to this type of
- vehicle are being studied by Aviation Week and several consultants.
- The variety of highly classified "black world" aircraft has prompted
- industry experts to suggest that the term "Aurora," which has been used in
- reference to a purported new classified hypersonic aircraft, may be
- inappropriate. Instead, Aurora may be one of several code names, all
- referring to a class of aircraft designed for multiple missions.
- A line item identified as "Aurora" in a Fiscal 1986 Procurement Program
- document dated Feb. 4, 1985, supposedly was simply one "site" for B-2 bomber
- funds when that program was highly classified, according to a government
- official. Listed under the "Other Aircraft" category, "Aurora" was projected
- to receive sharply increased funding. The Fiscal 1986 budget request for
- Aurora - $80.1 million - jumped to $2.272 billion in Fiscal 1987, according
- to the document.
- ...Several of the secret aircraft believed to be based in Nevada may be
- experimental or prototypes. At least one type has advanced to the production
- and deployment phases, and may be capable of hypersonic flight, according to
- officials who have been closely associated with classified programs at
- several Nevada test sites in recent years. One senior official said, "We
- don't really do anything strictly for experimental reasons. There's usually
- an operational twist." Several of these people had hands-on experience with a
- number of the classified vehicles.
- Although prevented from discussing specific projects, these individuals
- said, "There are bigger and better things out there," referring to aircraft
- based at the Nevada test locations...
- ...Knowledgeable government officials, charged with oversight and
- funding of military programs, however, continue to be extremely skeptical of
- reports about secret hypersonic aircraft based in Nevada. One respected
- official said he is confident that there is no such thing as a class or
- family of high-speed aircraft code-named Aurora, either in name or in fact.
- Industry experts who have worked on "deep black" programs, however, believe
- that it would be highly unusual for all but a very few political officials to
- have access to or knowledge of these programs. History has shown, they
- maintain, that elected officials and their staffs are poor security risks.
- Sensitive information, they say, will invariably be leaked through these
- channels if it is perceived politically advantageous to do so. *
- The preceeding article was quoted only in part. It was much too
- long to quote in its entirety. I suggest that you find the Oct.
- 1, 1990 issue of Aviation Week & Space Technology for it is a
- fascinating article. This is the first time they have even ad-
- mitted to any unusual activity at the Nevada test site other
- than earlier sightings of F-177As.
- Be sure to read the next message for another article pertaining
- to the same thing from the same issue.
- MULTIPLE SIGHTINGS OF SECRET AIRCRAFT HINT AT NEW PROPULSION,
- AIRFRAME DESIGNS
- Multiple reports from well-qualified observers lend substantial credence
- to the existence of numerous secret aircraft flying from remote bases in the
- southwestern U.S., regardless of the political, funding or technical
- arguments against that probability.
- Over the past 13 months, large, triangular wing-shaped aircraft
- characterized by a relatively quiet propulsion system have been the objects
- of at least 11 sightings near Edwards, AFB, Calif., and one near Fresno,
- Calif. These are supported by additional reports of similar vehicles seen and
- heard around remote central Nevada communities near government ranges
- operated by the Energy Dept. and the Air Force.
- Possibly prototypes of concept demonstrators of the Air Force B-2 or
- Navy A-12, the fairly flat, triangular-shaped vehicles have a rounded nose,
- rounded wingtips and probably no vertical tail surfaces. The flying wings'
- trailing edges may be slightly curved, but definitely are not sawtooth-shaped
- like those of the Air Force's B-2 bomber, according to reports received so
- far. One ovserver in Nevada described the shape as "like a manta ray."
- Key sightings include:
- * A daytime observation near the Tehachapi mountains (about 30 mi.
- northwest of Edwards AFB) in early May verified this craft's triangular
- shape. Numerous earlier sightings had been at night, although several were
- under a near-full moon that provided enough illumination to identify a large,
- triangular planform. The Tehachapi report noted that the aircraft was
- light-colored, but had a dark area near the center of the trailing edge,
- presumed to be the engine exhaust area.
- * On the night of May 3, 1990, a quiet aircraft matching the triangular
- description was reported by five different observers over a 4-hr. period. One
- or more of the aircraft made multiple passes over Tehachapi, Mojave,
- Lancaster and Palmdale, Calif., during this time.
- * A triangular aircraft also has been seen flying with multiple-ship
- Lockheed F-117A flights. Typically, the stealth fighters fly alone, spaced
- about 8-10 min. apart - a general pattern that has characterized F-117
- operations since they were first observed in California in mid-1989.
- However, on several occasions, the larger, traingular aircraft appeared
- on the same general flight path as the F-117As. It was seen after about three
- or four of the stealth fighters had passed, yet was ahead of another three or
- four. It has been spotted repeatedly over the northern end of the Antelope
- Valley, near Edwards AFB and Mojave, Calif., as well as in central Nevada.
- This vehicle is quiter that the F-117As - which already are
- substantially quieter than an F-15 or F-16 - and definitely larger. It
- normally displays a lighting pattern similar to that of the F-117s - single
- amber lights under the wingtips and a red beacon near the nose - but can be
- distinguished by its characteristic hushed engine noise and larger planform.
- All observer descriptions of the triangular aircraft correlated closely,
- and the observer who reported seeing the vehicle before sunset sketched a top
- view. That sketch matched descriptions of similar vehicles supposedly seen in
- Nevada-based government hangars several years ago and flying in military
- operating areas nearby...
- ...A totally separate, distinctly different type of aircraft seen and
- heard in California and Nevada over the last year is characterized by a loud,
- very deep, rumbling engine noise, At times, the exhaust noise is punctuated
- by a slow-frequency (about 1 Hz.) pulsing sound, which has prompted observers
- to call this aircraft the "pulser." The aircraft also produces a
- sausage-link-shaped smoke trail or vapor contrail when it is pulsing. This
- vehicle is not the triangular-shaped aircraft discussed earlier, and may be
- capable of hypersonic speeds.
- At other times, however, the aircraft exhibits a more continuous noise
- without the pulsing characteristic. Observers are confident it is the same
- type of aircraft, based on its distinctive deep, loud roar.
- There have been multiple reports of "pulser" flights, including:
- * The first, in July, 1989, at about 3 a.m. near Edwards AFB, Calif. The
- vehicle was at medium altitude, flying very fast and exhibiting the
- characteristic pulsing sound. The "pulser's" position was marked by a *white
- glow*, rather than a distinct point of light.
- * An early evening takeoff from Edwards AFB on Oct. 18, 1989.
- * Multiple reports of an aircraft having a deep, pulsing roar flying
- over central and eastern Nevada during the early morning hours throughout the
- past year.
- * Eight separate reports of an aircraft exhibiting the same
- characteristics, always flying on a northerly heading near Mojave, Calif.,
- between midnight and about 5 a.m. It was typically at lower altitude and
- slower speeds than when first seen in July, often had a slower pulsing sound
- and displayed only two position lights.
- * Six reports of an extremely fast-moving vehicle in southern
- California's skies, ranging from Santa Barbara on the Pacific coastline to
- near George AFB at the eastern end of the Antelope Valley. These aircraft
- typically were flying at very high altitude, were seen as a *single bright
- light*, and seldom changed direction. Speed changes have been observed, and,
- on occasion, a pulsing red or white light was seen. Whether these so-called
- fast movers also are the "pulser" aircraft is not known.
- A Santa Barbara observer estimated the aircraft crossed "some 350 mi. of
- night sky off the Pacific Missile Range bases in about 6 min." (about 3450
- mph!) One Aviation Week & Space Technology editor estimated a similar
- aircraft - seen as a bright point of white light - required less than 20 sec.
- to transit about 70 deg. of sky...
- ...On Oct. 18, 1989, the "pulser" apparently took off from North Base,
- an airfield at the north end of the Edwards AFB complex primarily devoted to
- classified programs. The noise from that takeoff was described as extremely
- loud, with a deep, throaty rumble that shook houses 16 mi. away, drawing
- residents into the street. One observer claimed the noise compared with that
- of Saturn 5 rocket tests conducted at Edwards AFB in the 1960s and 1970s.
- Although no lights were seen, the deep, vibrating roar continued for
- about 5 min., and its source appeared to be climbing steeply to the north.
- "Your eyes tended to follow the noise; something was climbing at a very steep
- angle," one observer noted. Residents of surrounding communities reported
- that the sound "was like the sky ripping," and was unlike anything they had
- heard in the Edwards area for years.
- The same pulsing, very loud, rumbling type of engine noise has been
- reported by multiple observers in central Nevada as well. It typically was
- heard in the early morning hours and was described as having a 1-2 Hz. pulse
- rate. One Nevada-based observer said tha same pulsing aircraft departed from
- the Groom Lake range and flew over a neaby community as recently as Aug. 6.
- It was "the loudest thing I've ever heard. It wasn't breaking the sound
- barrier, but it was rattling the window!" *
- An interesting note: one of the drawings accompanying the text
- shows the object as a very rounded triangular shape glowing
- orange!
- Again, this was only part of the article. I'll be watching future
- issues of Aviation Week & Space Technology for any updates. They
- are justifiably very reluctant to speculate very much on things
- of this nature. I'm sure you're aware that Phil Klass is a
- contributing editor to the magazine.
