CHARLOTTE, N.C., Dec. 11, 2012 /PRNewswire/ --UTC Aerospace Systems developed
and manufactured the space flight actuation system and remote interface unit
supporting the recent successful flight of the X-37B Orbital Test Vehicle
(OTV). The X-37B is a new space vehicle designed by Boeing, in conjunction
with the U.S. Air Force, to help make access to space more routine, affordable
and responsive. UTC Aerospace Systems is a unit of United Technologies Corp.
(NYSE: UTX).

The X-37B OTV is an unmanned space vehicle used by the U.S. Air Force to
research reusable space vehicle technologies. UTC Aerospace Systems delivered
the flight actuation system and part of the command and data handling
sub-system. The flight actuation system includes an electronic controller
that rapidly and precisely positions the multiple flight control actuators and
surfaces in response to commands from guidance and navigation computers. This
system plays a key role in the autonomous landing phase of the flight.

The UTC Aerospace System fourth generation remote interface unit fitted to the
orbital test vehicle is also central to the command and data handling
sub-system. The remote interface unit connects many of the vehicle's sensors
to the central computer and relays guidance instructions from the computer to
various vehicle sub-systems during the mission.

Andreas Nonnenmacher, vice president ISR Systems said, "During the last
landing, the avionics suite performed exceptionally well supporting the
successful development and demonstration of this new vehicle."

The X-37B program transitioned to the U.S. Air Force after earlier funded
research efforts by Boeing, NASA and the Defense Advanced Research Projects
Agency (DARPA).

UTC Aerospace Systems designs, manufactures and services integrated systems
and components for the aerospace and defense industries. UTC Aerospace Systems
supports a global customer base with significant worldwide manufacturing and
customer service facilities.

United Technologies Corp., based in Hartford, Connecticut, is a diversified
company providing high technology products and services to the building and
aerospace industries.
