When it comes to keeping ground troops safe, close enough isn’t good enough. That’s why precision-guided projectiles are playing such an important role on today’s battlefield.

Raytheon recently introduced the new Precision Extended Range Munition, or PERM, a guided projectile designed for the U.S. Marines. PERM is a small, smart, precision mortar that’s tube-launched and uses GPS guidance. It has double the range of current ballistic mortars and its capabilities help reduce collateral damage.

While PERM is just being fielded, the Excalibur is a revolutionary cannon artillery projectile that’s been fired hundreds of times in combat. Excalibur can also engage targets precisely at long ranges, while avoiding collateral damage.

“When ground troops fire a PERM or Excalibur, there’s no doubt they will hit the target,” said Mark Hokeness, Raytheon Excalibur and PERM program director. “They are proven time and time again in combat and in testing

Excalibur has been deployed to the U.S. and to several other countries around the world, including Sweden, Canada, Australia and the Netherlands. Other international partners are finalizing procurement plans.

The Excalibur projectile has been tested and proven compatible in multiple systems, including the M777, M109 series, M198, the Archer and PzH2000. It’s also been fired from the AS90, K9 and G6 howitzers.

Before Excalibur made its mark on the battlefield, ground troops were much more reliant on close air support, which was not always readily available. 

“Excalibur is the only long-range precision fires weapon that a commander can call on 24/7,” said Paul Daniels, an Excalibur and PERM business development manager.

The projectile is GPS-guided. “It doesn’t matter if there’s a sandstorm or a rainstorm, Excalibur is effective in all weather conditions,” Daniels said. “It hits the target, the first time, every time.”

Raytheon is building on Excalibur’s legacy, developing a 5-inch variant called the Excalibur N5. The sea-based variant is expected to more than triple the maximum range of conventional five-inch munitions and will provide the same accuracy as the land-based version.

The company has also successfully demonstrated a laser-guided version of the projectile, the Excalibur S. This variant has the ability to redirect in flight in case the target moves.

Last December, the U.S. Marine Corps closed a deal with Raytheon to ready PERM for its use by mortar crews.

Like Excalibur, it’s a precision-guided projectile; however, PERM is tube launched, allowing warfighters to use the weapon in confined spaces.

“It’s precise. It’s long range. It’s effective,” Hokeness said. “And it protects the warfighters who protect the world.”
