И ТТХ этого самолетика:

Northrop Grumman X-47 Pegasus
Type
Experimental naval UCAV.
Development
US$2.3 million DARPA/US Navy feasibility study contracts were awarded to Northrop Grumman and Boeing
on 30 June 2000 for a future US Naval Unmanned Combat Air Vehicle (UCAV-N), to be operable from
aircraft carriers. Phase 1A of this contract was completed in March 2001, followed by the US$25 million
Phase 1B; Phase 2, in which one or more companies will be selected to pursue development, was due to begin
in late 2001 or early 2002.
A full-size mockup of the Northrop Grumman design, later dubbed X-47A, was rolled out on 26 February
2001; roll-out of the first flying prototype took place on 30 July the same year. Primary purpose of this aircraft
will be to establish suitability of the basic design for carrier use, including arrester wire landings on a
simulated carrier deck at the US Naval Air Warfare Center, China Lake, California. Design of a more
definitive UCAV-N, designated X-47B, is expected to be frozen in early 2002; the eventual selected type is
planned to enter the EMD phase within the 2008 to 2010 time frame.
Variants
X-47A: Proof of concept prototype; due to make first flight in fourth quarter of 2001. Detailed description
applies to this version.
X-47B: Larger and modified development of X-47A as UCAV-N demonstrator.
Airframe

Stealth design, of all-carbon composites; manufactured by Scaled Composites Inc. Diamond-shape planform,
with 55º sweepback on leading-edges and 35º of forward sweep on trailing-edges. Large elevon in centre of
each trailing-edge; forward of these (two in wing upper surface and two in lower surface) are four `inlaid'
moving surfaces that provide a control function similar to that of a split rudder. No tail surfaces. Retractable
tricycle landing gear, with twin-wheel main units and single nosewheel.
Mission payloads
As appropriate in eventual UCAV-N for surveillance, SEAD or strike missions.
Guidance and control
Preprogrammed. BAE Systems avionics and vehicle management system.
Launch
Conventional wheeled take-off.
Recovery
Conventional wheeled landing, using US Navy's Shipboard Relative GPS autoland system.
Operational status
Under development.
Specifications
Power plant
One 14.19 kN (3,190 lb st) Pratt & Whitney Canada JT15D-5C turbojet. See under Weights for fuel details.
