STRATFORD, Conn., Sept. 26, 2013 /PRNewswire/ --Sikorsky Aircraft Corp., a
subsidiary of United Technologies Corp. (NYSE: UTX), this week begins final
assembly of the prototype S-97 RAIDER™ helicopter following acceptance of the
fuselage structure from Aurora Flight Sciences. Consisting of an integrated
cockpit, cabin and tail cone, the composite fuselage arrived September 20 at
Sikorsky's Development Flight Center in West Palm Beach, Fla., where the
company will complete a light tactical rotorcraft designed to outmatch
conventional military helicopters in speed, maneuverability, payload, range,
and high altitude operations.

"The first fuselage marks a significant milestone for the industry-funded
RAIDER helicopter program," said Debra Zampano, Sikorsky S-97 RAIDER Program
Director. "Aurora has delivered an advanced composite aerostructure designed
for our rapid development program. The Sikorsky team is now ready for final
assembly of the prototype RAIDER aircraft. We look forward to showcasing the
aircraft's exceptional performance and value to the U.S. military."

Sikorsky will convert the fuselage into a 36-foot-long, 11,000-lb.-gross
weight S-97 RAIDER prototype aircraft. Configured to Sikorsky's X2^® coaxial
design, the fly-by-wire controlled helicopter will feature counter-rotating
rigid main rotor blades for lift and forward flight, and a pusher propeller
for high speed acceleration and deceleration.

Sikorsky proved the efficiency of the rigid rotor co-axial design in 2010 when
its 6,000-lb. gross weight X2 demonstrator helicopter achieved 250 knot flight
speed, or twice the speed of conventional helicopters. It also demonstrated
low pilot workload and low acoustic signature.

The RAIDER prototype aircraft will improve on the X2 demonstrator by
showcasing precision maneuvers in low flight speed, high G turning maneuvers
at over 200 knots, hot day hover performance at altitudes up to 10,000 feet,
and significant improvements in payload and flight endurance compared with
conventional light tactical helicopters.

Aurora Flight Sciences is one of 36 industry teammates fabricating components
for the Sikorsky-led RAIDER program. The mostly carbon fiber fuselage
structure was fabricated at Aurora's manufacturing facility in Bridgeport, W.
Va.

"The RAIDER fuselage was designed around a set of rigorous requirements
necessary for this next-generation aircraft," said Aurora President and Chief
Operating Officer Mark Cherry. "We applied our experience developing the
composite main rotor pylon for the Sikorsky-built CH-53K heavy lift
helicopter, and consequently our understanding of Sikorsky's design and
manufacturing methodologies, to influence the RAIDER fuselage's preliminary
and detailed designs, and subsequent development of the associated tooling."

From the start of conceptual design in late 2010, Sikorsky has pushed
development of the S-97 RAIDER helicopter within a rapid timeline. Sikorsky
intends to begin demonstrating the RAIDER helicopter's game-changing flight
capabilities to the U.S. military and other potential customers in 2015.

"Sikorsky chose its teammates in 2011 based on their capability to deliver
mature advanced technology products and systems," said Mark Miller, Sikorsky's
Vice President of Research & Engineering. "Following completion of a
system-level critical design review in early 2013, the entire RAIDER team has
moved quickly into parts fabrication. We thank Aurora for delivering a
fuselage on which we can build an aircraft with a generational leap in
performance capability."

Sikorsky Aircraft Corp., based in Stratford, Conn., is a world leader in
