"This partnership with XCOR will provide unique insights and innovations,"
said Andrew Jackson, vice president of ATK's Aerospace Structures Division
Launch Segment. "ATK is honored to continue our heritage in creating composite
manufacturing solutions for spaceflight and excited to engage in this
commercial environment with XCOR."

"As an established industry leader it is only natural that XCOR sought to work
with ATK as a key collaborator in the development of Lynx wings," said XCOR
Chief Executive Officer Jeff Greason. "Our engagements with ATK impressed me
from the start, not only due to their position as a leader in the industry,
but through their immediate grasp of the unique challenges we face in the
construction of Lynx wings. The story of Lynx is the story of sound design and
reliable engineering. We could not be more thrilled to work with ATK."

XCOR Chief Operating Officer Andrew Nelson added that "until recently NewSpace
companies and established aerospace primes like ATK often had minimal
interaction with companies like XCOR as the subcontractor. With this effort we
are establishing a model of how smaller NewSpace companies may utilize
established government primes as our suppliers; ATK has demonstrated they are
nimble, cost effective and can leverage deep experience from prior larger

The initial wing and control surface design has been developed by XCOR to
rigorous design standards to enable the craft to perform tens of thousands of
flights to and from suborbital altitudes exceeding 100 kilometers. ATK will
create a detailed design ready for manufacture, working with structural and
flutter analysis experts from Quartus Engineering in San Diego, Ca. The wings
will be installed on the Lynx Mark I, which is the prototype of the Lynx
family of suborbital RLVs from XCOR; the production models are called Lynx
Mark II.

currently starting the process to create a new Research and Development Center
in Midland, Texas. XCOR builds safe, reliable and reusable rocket-powered
vehicles, propulsion systems, advanced non-flammable composites and rocket
piston pumps. XCOR works with aerospace prime contractors and government
customers on major propulsion systems, while also building Lynx. Lynx is a
piloted, two-seat, fully reusable liquid rocket-powered vehicle that takes-off
and lands horizontally. The Lynx-family of vehicles serves three primary
missions depending on their specific type including: research & scientific
missions, private spaceflight, and micro satellite launch (only on the Lynx
Mark III). Lynx production models (designated Lynx Mark II) are designed to be
robust, multi-mission (research / scientific or private spaceflight)
commercial vehicles capable of flying to 100+ km in altitude up to four times
per day. Lynx vehicles are available to customers in the free world on a wet
lease basis. (www.xcor.com).
