PUBLICATION : JANE'S UNMANNED AERIAL VEHICLES AND TARGETS
VOLUME/ISSUE : 20
DATE : 2005 Mar 11
UPDATE STATUS : UPDATED
SECTION : UAVs
COUNTRY : United States
TITLE : Boeing X-45
Combat UAV for electronic attack, SEAD and other missions.
Four contractor teams were each awarded a US$4 million Phase 1 advanced
technology demonstration (ATD) contract by DARPA in April 1998. The
Lockheed Martin team subsequently withdrew, and in March 1999 the Boeing
design was selected in preference to those submitted by Northrop Grumman
and Raytheon. A DARPA/USAF 56-month contract valued at US$191 million, to
which Boeing contributed US$21 million, was awarded to Boeing's Phantom
Works on 24 March 1999. Under this, Boeing has completed two X-45A air
vehicle demonstrators. USAF funding up to FY07 has been earmarked to
include two larger Phase 2 X-45B prototypes.
Boeing's Seattle location is responsible for the mission control and
overall programme management; St Louis has the lead for the air vehicle
segment. Development utilises experience gained in the Boeing X-36
programme (which see). Purpose of the ATD programme is to establish
whether an affordable UCAV can be developed for service entry in about
X-45A: Spiral 0 subscale prototypes, also known as UOS-4h; powered by
Honeywell F124 engines. First of two rolled out 27 September 2001;
completed low-speed taxi trials 2 November 2001; medium- and high-speed
taxying in February to April 2002. First flight made at Edwards AFB,
California (NASA Dryden Flight Research Center), on 22 May 2002; lasted
14 minutes, reaching 195 kt (361 km/h; 224 mph) and altitude of 2,286 m
(7,500 ft). Second flight (32 minutes) 13 June 2002; then grounded for
software update; three more flights in October and one in December 2002,
by which time second X-45A also flown (22 November for 29 minutes). First
prototype due to have cleared flight envelope by mid-2003 (Block 1), when
to be joined for Block 2 (multivehicle testing) by second X-45A. Block 3
(mission replanning, station-keeping and simulated drop of inert weapon)
due to begin at end of 2003, followed by Block 4 (transfer of
decision-making from ground to air) for completion by end of 2004.
X-45B: Originally planned as two larger, fieldable, baseline Spiral 1
prototypes (also known as UOS-04L) for operational UCAV; powered General
Electric F404-GE-102D engines. Increases in wing span (22 per cent), wing
area (63 per cent), length (11 per cent) and empty weight (31 per cent).
Two internal weapons bays, of same length as those in F-35 Joint Strike
Fighter; able to carry 907 kg (2,000 lb) of weapons; typically two 454 kg
(1,000 lb) Boeing JDAMs or up to eight small-diameter bombs (SDBs). First
flight targeted for late 2004. Block 5 to demonstrate attacks on radar
sites and flight with manned aircraft and reconnaissance UAVs. Block 10
would have continued development for SEAD and strike missions. Reactive
air defence suppression was to have begun in late 2005 (Block 20), leading
in 2008 to Block 30, in which the UAV would have been equipped with
However, it was reported in February 2003 that DoD planned to cancel
X-45B in favour of X-45C to gain significant increase in range and
A-45: Provisional designation for Spiral 2 initial operational version
of X-45B. Parameters currently include 900 n mile (1,666 km; 1,035 mile)
radius with 1,633 kg (3,600 lb) useful load (two JDAMs, two 1,135 litre;
300 US gallon; 249 Imp gallon drop tanks, two miniature air-launched
decoys and up to 12 SDBs). Service entry in 2008.
X-45C: Proposed by Boeing in early 2003. Would be even larger than
X-45B, with new bat-shaped wings, offering increased payload/range
trade-off, including full range more than double that of F-35 JSF.
According to a February 2003 report, X-45B funding had been diverted to
