Corporation
E´Prime Aerospace Corporation
(EPAC) was established in early 1987 with a commercial
space transportation system based on the US Air Force MX Peacekeeper programm.
The Eagle series launch vehicles will be proposed for launches from Ascension Island
for geosynchronous satellites and from Vandenberg AFB for polar spacecraft. As a
first phase of development, EPAC is proposing four models in the Eagle series:
Small two-solid stage Eagle with liquid upper stage to place up to 1.35 tons in a 360-km circular orbit. The third stage which is for orbital accuracy, is called Post Boost Vehicle (PBV) and is specially developed by EPAC.
Large two-solid stage Eagle S-I plus PBV to launch up to 2.7 tons in LEO or 1.5 tons in polar orbit (SSO) or 0.935 tons in GTO.
Three-solid stage Eagle S-II plus PBV to put 4.5 tons in LEO or 2.5 tons in SSO
Three-solid stage Eagle S-III plus restartable USTM (Unified Satellite Transfer Module) to put 4.5 tons in LEO or 2.0 tons in GTO. USTM designed by EPAC and it used with a restartable engine with high specific impulse.

Continuing the tradition of deriving commercial
launch vehicles from U.S. Air Force Intercontinental Ballistic Missiles (ICBMs),
E' Prime in 1987 was given the right under an amendment to its Commercialization
Agreement with the U.S. Air Force to derive the Eagle S-Series of launch vehicles
from Peacekeeper ICBM technology. E' Prime now has the go-ahead to use this technology
and market the Eagle S-Series Launch Vehicles as a commercial satellite launcher.
With over 40 consecutive launches of the Peacekeeper by the USAF, without a single
failure, the Peacekeeper is the most advanced and successful rocket in the world
today.
E' Prime Aerospace Corporation (EPAC or the Company) provides commercial
launch services for satellite companies or National launches. Launch services offered
by EPAC include provision of the launch vehicle, launch site, integration of the
payload with an appropriate protective fairing and deployment features, preparation
of range documentation, payload processing facilities, assembly, test, countdown,
launch and post launch control, and orbital verification operations. Payload integration,
mission definition, configuration management, launch and flight operations are also
conducted by EPAC.
E' Prime Aerospace was established in February, 1987. In October 1987, an
agreement signed with United States Air Force (USAF) provided EPAC the use of technology
based on the Peacekeeper solid fuel missile system.
In November, 1988, E' Prime launched the first fully commercial rocket in
U.S. space history from Cape Canaveral Air Force Station, Florida. Loft 1, a small
sub-orbital rocket, carried 34 pounds of payload (micro gravity experiments) on
a short ballistic flight downrange and was used as a "Path Finder" to determine
the launch requirements of the Department of Transportation and the Eastern Test
Range. This historic flight was the start of commercial launch operations in the
U.S., and received international press coverage. In early 1990, the Peacekeeper
first stage motor was included in the Strategic Arms Reduction Treaty (START), which
was signed by both the governments of the United States and the former Soviet Union.
Following the execution of this treaty, the Company was prohibited in producing
EPAC's first stage motor. For nine years, EPAC's development concentrated on redesign,
new technologies and the preservation of the technology developed during the Peacekeeper
program.
EPAC is marketing a range of launch vehicles with payload capabilities from
communications satellites up to large multipurpose satellites of 20,000 pounds into
a geosynchronous earth orbit (GEO) 22,300 miles above the earth). Small and medium
lift single core vehicles are launched from a launch tube, which propels the rocket
some 200 feet into the air before the first stage is ignited. This cold launch method
increases the payload capability by approximately 10% and prevents costly refurbishment
to the launch facility. The following is live video of the Peacekeeper Technology
acquired by EPAC (launch video).
Eagle launch vehicles are a modular design of solid propellant booster stages
and a liquid bi-propellant upper stage. This unique modular design of four (4) interchangeable
motor configurations allows a vehicle to be configured to fit a specific payload
requirement. The primary benefits of the Eagle Series vehicles are reliability of
solid fuel, rapid response time, ease of launch, and low cost (20% to 60% of competitors).
The Company believes that these benefits provide a distinct advantage in the world
launch market.
The Federal Aviation Administration projects commercial launches to be 32
per year through 2010. National launches will depend on the development of The Missile
Defense System, but even without it the total number will be higher. Both commercial
and National users are demanding lower cost access to space. EPAC and the Eagle
Series of launch vehicles are poised to meet these requirements.
Where possible, the same companies that were responsible for the manufacture
and supply of materials for the Peacekeeper will produce flight hardware for the
Eagle Series launch vehicles. EPAC solid rocket motors (SRM) will be produced using
the latest technology available for the mass production of SRMs. By using the experience
of these suppliers, the record of accomplishment and reliability experienced during
the Peacekeeper missile system program is carried forward into a commercial application
while significantly lowering production cost.
In October 1987, EPAC signs an agreement with United States Air Force (USAF).
In November, 1988, E' Prime launched the first fully commercial rocket in U.S. space
history from Cape Canaveral Air Force Station. In early 1990, the Peacekeeper first
stage motor was included in the Strategic Arms Reduction Treaty (START). In 1998,
EPAC, using Peacekeeper baseline technology, improved design changes, and development
of the ESM-9 first stage motor in a 100% commercial environment, eliminated the
ESM-9 from the START Treaty. In 1999, EPAC completed commercialization of the Peacekeeper
missile system for ELV applications.
