The Army is advancing effort to upgrade the radar, fire control technology and flight software for its PATRIOT missile in order to
sharpen its target tracking ability against approaching enemy attacks.
The Army has awarded a contract-extension with Lockheed Martin to
further develop these technological advances for the weapon.
The $ 13.4 million modification includes
engineering services for phased array tracking radar intercept on the
PATRIOT Advanced Capability 3 (PAC-3) Missile Segment Enhancement (MSE) -
also known as PAC-3 MSE.
“The PAC-3 MSE program includes flight software,
flight testing, modification and qualification of subsystems, production
planning and tooling, and support for full Patriot system integration,”
according to Lockheed.
At the end of last year, the Army’s Patriot missile destroyed a
mock-enemy theater ballistic missile target in a recent test-firing in
order to demonstrate new guidance technology built into the weapon, Army
officials said.
The Patriot Advanced Capability-3 is an advanced kinetic energy
hit-to-kill interceptor surface-to-air missile designed to knock out
incoming threats and protect ground forces, buildings and other assets.
As a kinetic energy interceptor, the weapon relies upon the sheer force
of impact to destroy approaching enemy attacks and does not need to use
explosives – thus the “hit-to-kill” description.
The Patriot can be used for close-in threat approaching targets such
as drones, cruise missiles and even enemy aircraft. At the same time,
the missile can destroy longer-range theater ballistic missile targets
as well, Army officials have explained.
The missile system also functions in tandem with the Terminal High
Altitude Air Defense, THAAD, system to provide the U.S. with a
“multi-tier theater defense.”
To intercept an incoming missile, it steers towards
a predetermined intercept point chosen by its ground-based fire
solution computer, selects the proper trajectory, and then applies a
direct, body-to-body hit on the target.
In service since the early 80s, Patriot missiles have been upgraded
several times, including this latest MSE software improvement. This
test, which took place in December of last year, was engineered to asses
an even newer target-tracking technology called Post Deployment Build,
or PDB-8, service officials explained.
“PDB - 8 software is a major software build that provides improved
capability against the evolving threat and is fully compatible with the
IBCS (Integrated Battle Command System). The air and missile defense
threat continues to progress and proliferate, and the Patriot system is
continually evolving to deliver threat-paced capabilities in the current
and persistently-changing threat environment,” Dan O’Boyle, spokesman
for Program Executive Office, Missiles and Space, told Scout Warrior in a
written statement last year.
The PAC-3, which is deployed in military theaters around the world,
is a lower-tier, hit-to-kill missile and member of the Ballistic Missile
Defense System. It features a solid propellant rocket motor,
aerodynamic controls, attitude control motors and inertial navigation.
During last year's test, at White Sands Missile Range, N.M., the
Patriot used its Active Electronically Scanned Array to track data,
detect and engage the target, an Army statement said. The system uses
radar, sensors, guidance technology and an integrated fire control
technology to track and destroy targets.
“Preliminary test data indicates a successful Juno (Theater Ballistic
Missile-like) target intercept with missile number one and a successful
test flight. The test was conducted to:demonstrate the capability of
the PATRIOT system, using PDB-8 to detect, track, engage and kill a
threat representative TBM (Theater Ballistic Missile) with PAC-3 MSE
Missiles.
The Patriot is now in service with at least 13 countries around the
globe, including five NATO countries. Up to 16 PAC-3 missiles can be
loaded up into a launcher for increased firepower and defensive
capabilities. Also, the weapon is highly mobile and can be fired from an
Army Heavy Expanded Mobility Tactical Truck, or HEMTT.
Raytheon, Lockheed Martin and Boeing are all associated with Patriot missile development, technology and production.
The full $13.4 million modification amount agreed
upon for this most recent contract was obligated at the time of the
award. Work will be performed at the Army Reserve Center in Grand
Prairie, Texas and at the White Sands Missile Reserve in White Sands,
New Mexico. The estimated completion date is January 30, 2018. Army
Contracting Command, is the contracting activity.
