The Army's newest and most advanced Unmanned Aircraft System (UAS), the
Extended Range/Multi-Purpose (ER/MP) UAS, has successfully completed a
series of tests with the HELLFIRE® II UAS --- a missile specially
engineered to fire from a UAV with a 360-degree targeting ability,
service officials said.
The tests, involving nine perfect or near-perfect missile firings, took
place at the Naval Air Weapons Station, China Lake, Calif., and
demonstrated the missile's ability to engage a wider target envelope
than a typical Hellfire missile, said Tim Owings, Deputy Project
Manager, Army Unmanned Aircraft Systems.
"The significance to this is this is the first missile designed
specifically for a UAV. The HELLFIRE UAS missile can take advantage of
a 360 look around angle. The ball on the UAV can swivel 360 degrees --
and with this missile you can engage targets that are below you, behind
you and well off-axis from what a typical HELLFIRE can do," said
Owings. "There were nine successful shots. The big point is the laser
designation system, the weapons system and the UAV all performed as
designed and as expected. It was a really clean test."
The testing began Nov. 22, 2009, with the unmanned system first
performing dry runs against a target with an inert test missile on the
inboard rail of the right wing. After confirming data was transmitting
properly between the missile and aircraft and to the China Lake Range
Control Center, a successful "cold" pass using a live powered missile
took place, allowing the test to continue with an actual firing.
"The cold pass is assuring you have the missile locked on to the
target. The hot pass is when you go all the way to a weapons release,"
said Owings.
The firing, or "hot" pass, involved coordination between the mission
payload operator and air vehicle operator, or AVO, at precise waypoints
during the flight and then the AVO pressed the weapons fire button
sending the missile from the inboard rail of the left wing to the
target with a successful impact.
More demanding test firings, which took place in late November and
December, included assessing the capabilities of the system against a
variety of conditions such as firing at varying altitudes, against both
stationary and moving targets, and using different auto-track modes.
The system was also tested with firings happening at varying offset
angles; the HELLFIRE II UAS missile is capable of being fired in any
direction and correcting course to find and strike its target, allowing
for greater flexibility of use in combat situations.
The test series involved several months of integration testing between
the ER/MP contractor General Atomics-Aeronautical Systems, Inc.'s
Software Integration Laboratory, the El Mirage Flight Test Facility in
El Mirage, Calif., and Edwards Air Force Base prior to the firings to
ensure the software would perform optimally during live firings.
The test firing helped pave the way for the ERMP's successful
completion of a Milestone C review, marking approval for the UAS
Project Office to enter into Low Rate Initial Production.
"The milestone C authorized us for the procurement of two complete
systems of the Warrior and an additional eight vehicles for training
and replacement of war-loss vehicles," said Owings.
There are 12 aircraft in each system, Owings said.
The decision was rendered by the Department of Defense on Feb. 2, 2010,
following the program's review for compliance with all milestone
criteria and the successful completion of an Operational Assessment
test phase. The Milestone C review assessed production readiness and
program acquisition maturity.
A quick reaction capability of four weaponized vehicles are slated to deploy to Afghanistan in July of this year, Owings said.
"The process we've taken is to spin out technologies into theater as they mature," he added.
When deployed later this year, the new ER/MP unmanned aircraft system
will feature a heavy fuel engine, triple redundant avionics, and
redundant flight controls/surfaces, and network connectivity that
reduces information cycle time and enhances overall battlespace
awareness.
It is capable of flying for more than 30 hours, can operate with or
without satellite communications data links and, in addition to four
Hellfire missiles, it will carry a advanced targeting system for
immediate situational awareness and target detection.
