APKWS Laser-Guided Rocket

Currently in its third year of full rate production, the APKWS rocket is the only U.S. Department of Defense fully qualified guided 2.75-inch rocket. It uses semi-active laser guidance technology to strike both soft and lightly armored targets in confined areas, providing greater accuracy and mission effectiveness.

Developed as a highly cost-effective solution that leverages the military’s existing infrastructure and inventory – and inspired by real combat challenges, the APKWS rocket has served the needs of our U.S. armed forces with a 93 percent hit rate. Building on in- theater success by the U.S. Marines Corps, program officials from the U.S. Navy have now made the APKWS rocket available to U.S. allies by way of foreign military sales process.

The APKWS laser-guided rocket demonstrates extreme precision, reliability, and versatility in theater and in testing. The system also provides new combat capabilities for air, ground, and sea-based platforms.
  • Better than 93% hit rate
  • Demonstrated on more than 12 platforms
  • No modifications to the rocket, firing platform or fire control/launcher system needed
  • Minimal training needed for the crew

BAE Systems proposed another design, mounting the laser sensors on the stabilizers. As the stabilizers are recessed into the rocket body until it clears the launch tube, the sensitive seekers are also protected from environmental and thermal effects of the launch. The weapon retains both the original Mk66 Mod 4 rocket motor and M151 / Mk 152 4.53 kg (10-pound) high-explosive warhead adding the 18.5 inches (47cm) long integrated targeting and guidance section between the two segments. The overall length of the extended rocket is 1.87 m (73.8 inches) and its weight is 14.8 kg (32.6 pounds).

The upgrading of the standard 2.75″ rocket into APKWS using the plug-in assembly.This design proved superior to nose mounted seekers, as it offered important advantages, such as easier ‘plug in’ integration of the new system (without the need to move or change the warhead). Fiber-optic cables, enabling fast and reliable connectivity, link the seekers to the processor. With no modifications to the rocket (except for the addition of ‘plug-in’ guidance kit), the firing platform or fire control/launcher systems also remain intact, supporting the new precision fires capability.

In 2009 the Navy selected BAE Systems as a prime contractor for the weapon’s development and Low Rate Initial Production (LRIP) and, by mid 2012 approved the program for full rate production. To date BAE Systems delivered more than 5,000 rockets; more than 100 were used in combat, particularly by the US Marine corps in Afghanistan. Following the endorsement of the US services, the Pentagon has made the APKWS rocket available for export under the foreign military sales (FMS) process. Source
