U.S. <strong>Army</strong>/John Hamilton<br />

During testing at White Sands Missile Range, N.M., clockwise from top inset: An M270A1 MLRS fires a training rocket; an improved armored cab affords<br />

more crew protection; the redesigned cab puts the commander in the center.<br />

exploded ordnance … and with the different ways a bomblet<br />

can hit, there’s almost no way you can guarantee a less than 1<br />

percent dud rate.”<br />

The solution came in the form of the alternative warhead program.<br />

Lockheed Martin worked with Orbital ATK to develop a<br />

new warhead for the guided multiple launch rocket system that<br />

features a high-explosive core surrounded by tungsten balls.<br />

“We’re talking about 186,000” medium- and small-caliber<br />

balls, Musculus said, so when the rocket detonates, the smallcaliber<br />

balls are “going everywhere. It’s used for imprecisely located<br />

targets and also for soft targets.”<br />

The engineering and manufacturing development program<br />

for the new warhead program began in March 2012, Musculus<br />

said. Testing at White Sands Missile Range, N.M., resulted<br />

in “100 percent mission success,” with detonations providing<br />

“good effects on targets.”<br />

Tactical Missile Modernization<br />

Other efforts are directed toward old <strong>Army</strong> tactical missiles<br />

containing anti-personnel and anti-materiel (APAM) submunitions.<br />

“The government has a lot” of the Block I tactical missions<br />

in inventory, he said. “These are the old ones with the APAM<br />

warhead,” which will not be usable starting in 2018 because of<br />

the cluster munition ban.<br />

“So what we are doing is taking those old Block Is, bringing<br />

them in, downloading and de-mating them from the pod,<br />

salvaging a lot of the metal parts including the solid rocket<br />

motor, which we’re washing out and refilling the propellant<br />

so it’s like a brand-new motor,” he said. “We’re also building<br />

new navigation electronics and upgrading the processors; replacing<br />

the obsolete parts; doing the same replacement of obsolete<br />

parts for the mission computer and putting a new<br />

processor in there.”<br />

Musculus said new builds of the inertial measurement unit<br />

and control actuation system are also being added. As a result,<br />

what had once been seen as a service life-extension program<br />

is now dubbed modernization for the <strong>Army</strong>’s tactical<br />

missile system.<br />

“The systems are not stagnating,” Musculus said. “We are<br />

continuing to upgrade the electronics in them. We are putting<br />

new processors in. We are replacing the obsolete parts. We are<br />

developing new warheads that are compliant with policies and<br />

accords. We’re also putting new electronics in the launchers<br />

and have developed a new armored cab to protect the soldiers<br />

better. These are evolving products that are going to go on for<br />

many more years.”<br />

Musculus also said the restarted tactical missile system and<br />

HIMARS lines are attracting foreign interest. “Countries are<br />

now coming and saying, ‘Hey, we want to get in on that now.’<br />

So that’s a good story,” he said. “And where it’s really a great<br />

story is, as the foreign governments come in and buy these<br />

munitions, it obviously helps out our U.S. customer with better<br />

pricing.”<br />
