The recent Association of the United States Army (AUSA)
technology symposium served to highlight a wide range of Army missile
activities conducted in support of the ongoing "Army transformation" process.
The well-known "trident chart" frequently represents that
process, first outlined by Army Chief of Staff General Eric Shinseki in October
1999. Here the tridents prongs represents Legacy Force activities, Interim
Force activities and Objective Force activities.
Legacy Force Applications
Legacy Force transformation activities are currently
focused on the recapitalization of a selected number of critical weapon
systems projected to remain in Army inventories well into the foreseeable
future.
Although the current list of "recap" candidates has
decreased to 17 systems (down from 21 recap candidate systems last year), it
includes both the Patriot missile system and the Multiple Launch Rocket System
(MLRS).
In the MLRS example, recap activities are focused on
enhancements to the existing M270/M270A1 series launcher, while parallel
munitions development efforts hold the promise of expanding the utility of that
launcher in future operations. One key recap enhancement to the M270A1 MLRS
involves an upgrade to the launcher's mechanical system.
"It's called the Improved Launcher Mechanical System [ILMS],
which helps us to elevate and slew the launcher," Ben Collins, Lockheed Martin
business development manager, explained.
Briefing on the MLRS and related program activities, Collins
said, "We've been able to take that elevation and slew time down from over a
minute to just seconds. We actually decreased it from 73 seconds: From about a
minute and a half we're down to just 16 seconds. That was done purposefully for
survivability of the launcher system."Â
Current plans include the enhancement of 327 launchers with
new ILMS platforms, just starting to enter the field.
Additional system enhancements include Global Positioning
System (GPS) navigation capabilities that will allow the firing platform to
initialize future generations of GPS-guided smart munitions and smart
sub-munitions.
A relatively new derivative of the MLRS, the High Mobility
Artillery Rocket System (HIMARS), places a single pod of MLRS munitions on the
back of a 5-ton truck.
The system features C-130 aircraft roll on/roll off
capabilities for ease of both strategic and tactical deployment, along with GPS
navigation to facilitate the employment of future generations of smart
munitions.
Although initially developed as part of the Rapid Force
Projection Initiative (RFPI)/Advanced Concept Technology Demonstration (ACTD),
HIMARS is uniquely positioned to span all three points of the Army's
transformation trident.
"We've taken those M270A1 improvements and applied them for
the HIMARS," Collins said. "We actually built four HIMARS prototypes and sent
them to 18th Airborne Corps four years ago. The systems were only supposed to
be there for two years but [the 18th Airborne Corps] refused to give them up,
saying, â??We'll give up the prototypes when you give us an Engineering and
Manufacturing Development [now Systems Development and Demonstration] version.'
That presented a unique problem for the program manager who has to provide
logistics support for four prototypes that he's not going to build anymore. The
user refused to give them up because everyone loves the system."
The system has recently expanded to multiple service
application. As of this writing, Lockheed Martin is building six Systems
Development and Demonstration (SDD) launchers with four slated for delivery to
the Army and two to the Marine Corps.
Interim Force Applications
One current tactical missile activity supporting the
development of the Army's Interim Forces involves the Army's modification
of approximately 500 TOW missiles with "bunker busting" warhead characteristics.
The modified missiles will reportedly be used to provide the
Interim Brigade Combat Teams (IBCTs) with some level of battlefield bunker
attack capability while the units await completion and fielding of the Mobile
Gun System variant of the "Stryker" Interim Armored Vehicle (IAV) family.
In addition to its potential Legacy Force applications, the
HIMARS platform holds the possibility of enhancing Interim Force combat
capabilities.
Specifically, the system's C-130 roll on/roll off
capabilities position the platform as a "slice element" that could be provided
to the brigade combat teams during future deployments.
Although the IBCTs have organic fire support through their
current M198 (and future M777) 155 mm howitzers, the HIMARS would provide those
units with expanded fire support options from the expanding array of the MLRS
Family of Munitions (MFOM).
Examples of this recent MFOM expansion include the Guided
MLRS rocket, the Guided Unitary MLRS rocket, Unitary ATACMS (Army Tactical
Missile System), and the Loitering Attack Missile (LAM).
The Guided MLRS rocket, for example, which Collins described
as "a good success story for international programs," uses GPS guidance
technology to achieve "meter-level accuracy" at firing ranges of more than 60
km. Low Rate Initial Production (LRIP) is slated to begin in FY03 with Initial
Operational Capability projected for FY06.
Another guided MLRS munition under development is the Guided
Unitary Rocket. Instead of delivering sub-munitions over the target, the Guided
Unitary design will deliver a single 200 lb. unitary warhead with tri-mode fuze
to ranges in excess of 60 km. Army leaders approved the Operational
Requirements Document (ORD) for the rocket in September 2001.
Lockheed Martin representatives hope to demonstrate the
system in August of this year but note that the effort is competing for funding
in the current Program Objective Memorandum (POM).
Objective Force Applications
Lockheed Martin MLRS, HIMARS and MFOM activities are also
supporting tomorrow's Objective Force structures and capabilities.
One key component is the LAM. Currently in technology
demonstration status, LAM will provide a 280-km range with 45-minute loiter
time.
Initial design activities indicate that 12 LAMs could be
packaged in a single HIMARS launch pod. Tactical missile systems like LAM are
also seen as providing a key component of the emerging "system of systems"
structure that will comprise the pivotal Future Combat System (FCS).
During his AUSA presentation, Dr. Allen Adler, director of
the Defense Advanced Research Projects Agency (DARPA), noted, "We will have a
network of sensors and we will also have a network of fires."
He described a key concept within the network of fires that
would feature "a vertically launched missile system that could be brought in
close in the theater [of operations] to engage targets very quickly."
Known as "Netfires," the DARPA-managed network of fires
program (jointly funded by DARPA and Army Science and Technology activities)
targets the development and tests a containerized, platform-independent
multi-mission weapon concept as an enabling technology element for FCS.
Government program descriptions note that Netfires will
provide rapid response and lethality in packages requiring significantly fewer
personnel, decreased logistical support and lower lifecycle costs, while
increasing survivability with respect to current direct fire gun and missile
artillery.
Netfires will allow FCS to defeat all known threats; will be
air deployable in C-130 (and smaller) aircraft; and will enhance the situation
awareness and survivability of FCS by providing standoff target acquisition and
extended-range, non-line-of-sight engagements.
The program will develop and demonstrate a highly flexible
modular, multimission precision missile and a loitering attack missile that can
be remotely commanded. Both missile types will have a self-locating launcher
and a command and control system compatible with FCS.
"The Netfires systems that we're developing in this program
include a precision attack munition, basically a vertically-launched munition
that heads right for the target, closes in very quickly, and passes target
updates," Adler said. "The other missile that we're developing is the loiter
attack munition."
Adler complimented the work to date performed by the two
participating contractors, Raytheon Co. and Lockheed Martin Missiles and Fire
Control Division, adding, "As we move forward into the FCS, this is the type of
program that we want to accelerate."
Netfires' proof-of-principle flight tests are scheduled to
begin in FY03.
Paying the Bills/Positioning for the
Future
One of the greatest challenges in any service-wide
transformation effort involves paying the bills that invariably accompany that
process. It's a challenge for military planners as well as for contractors
supporting the process through technology investigation and hardware
development.Â
Army planners, for example, point to the termination or
restructuring of 18 different Army programs to generate the initial $9 billion
being used for transformation activities. One of those cancellations was the
"Fire-and-Forget TOW" missile program, under development by Raytheon.
"We were disappointed about Fire-and-Forget TOW, there's no
doubt about it," said Paul Walker, vice president of Raytheon Electronic
Systems. "That program was doing very, very well but leadership made a decision
and we're going to move on."
Walker highlighted the positive aspects of Raytheon's
positioning and activities during the Army's ongoing transformation process.
"There are a couple of dimensions that you have to think
about," Walker said. "One is that the inventory of TOW missiles - and Hellfire
missiles for that matter - is aging.
And there will reach a point in time, somewhere in the 2005
to 2008 time period, where the reliability of that inventory would be such that
you would logically want to replace it. Bradleys [Bradley Fighting Vehicles]
are going to be on the battlefield for 25 years and Apaches are going to be out
there as well. It's the Army's intent, I believe, to fill that need with Common
Missile.
The Common Missile will effectively engage and destroy a
variety of targets, ranging from buildings and bunkers to advance armor on the
digital battlefield well into the future. It will be designed to achieve
greater range and survivability, while decreasing the missile's weight and
size.
"So then the dimension is, can you get Common Missile - you
can call it Block I - into the field in time to fill that inventory problem that
the Army will have?" Walker asked. "And the Army's problem is not just now with
its Legacy Force systems, but by 2010 there has to be some lethal device on an
FCS. Certainly there has to be something to replace TOW on IAV-AT [Interim
Armored Vehicle-Anti Tank (variant)]. I believe the Army is committed at this
time to Common Missile as that capability. Certainly Common Missile is
designated as the lethal mechanism on Comanche. FCS is open, I guess, to what
the LSI [Lead Systems Integrator] decides to do."
"The other dimension comes along as you look further down
the road and you've got systems like Netfires coming into play and you've got
systems like CKEM [Compact Kinetic Energy Missile] coming along for FCS," he
said. "And then it's a matter of â??How do you divide the battlespace?'Â Is
everything line of sight dealt with by a CKEM-like weapon and everything
non-line of sight dealt with by Netfires? In that case you don't need a â??just
beyond line of sight' kind of weapon like Common Missile, except perhaps for
aviation."
He described the potential expansion of several weapon
systems, to include the possibility of placing the man-portable Javelin
anti-armor missile in a vehicle-mounted configuration.
"I think we're positioned in all of those areas," Walker
concluded. "The biggest thing that the Army and the LSI that they have selected
need to do is to figure out the CONOPS [Concept Of Operations] for FCS and sort
out how those weapons fit into that CONOPS. So we're going to go pursue the
technologies; we're going to build the stuff that we think they are going to
need. They just have to sort out the CONOPS part."
