Lockheed Martin delivered to the Office of the Under Secretary of Defense for Research & Engineering OUSD (R&E) a new benchmark: a tactically-relevant electric 300 kW-class laser, the most powerful laser that Lockheed Martin has produced to date. This 300 kW-class laser is ready to integrate with the DOD demonstration efforts including the U.S. Army’s Indirect Fires Protection Capability-High Energy Laser (IFPC-HEL) Demonstrator laser weapon system.
The OUSD (R&E) selected Lockheed Martin in 2019 to scale its spectral beam combined high energy laser architecture to the 300 kW-class level as part of the High Energy Laser Scaling Initiative (HELSI), and the team recently achieved that milestone ahead of schedule.
«Lockheed Martin increased the power and efficiency and reduced the weight and volume of continuous-wave high energy lasers which reduces risk for future fielding efforts of high power laser weapon systems», said Rick Cordaro, vice president, Lockheed Martin Advanced Product Solutions.
The HELSI laser will support demonstration efforts with the Army’s IFPC-HEL, which is scheduled for laboratory and field testing this year.
This recent HELSI delivery milestone also exemplifies Lockheed Martin’s commitment to 21st Century Security, developing advanced technologies that provide speed, agility, and mission solutions that help ensure the U.S. and its allies are always prepared for what’s ahead.
Lockheed Martin’s 300 kW-class high-energy laser design and build was enabled by significant investments in directed energy technology and the contributions of the company’s dedicated team in Washington state and Owego, New York. The team is applying more than 40 years of experience researching, designing, developing, and capturing electromagnetic energy and elevating its power to create innovative 21st century security solutions.
The Army recently conducted a successful evaluation of a new directed-energy capability, moving the service one step closer to fielding a platoon of four laser-equipped Stryker combat vehicle prototypes next fiscal year, program leads said Wednesday.
The Directed Energy Maneuver-Short Range Air Defense system, or DE M-SHORAD, is a 50-kW-class laser designed to protect divisions and brigade combat teams against unmanned aircraft systems, rotary and fixed-wing threats, rockets, artillery, and mortars, said Marcia Holmes, the deputy director of hypersonics, directed energy, space and rapid acquisition.
«Our goal is to deliver prototypes that Soldiers can use as the mission requires and that the Army can leverage as a baseline for a program of record», Holmes said. «A Soldier-centered design is a key part to reduce risk and to ensure an operationally effective weapon system».
A strong partnership between the Army Rapid Capabilities and Critical Technologies Office and science and technology industry leaders led to the development and implementation of the first prototype in 24 months, Holmes said.
The addition of the DE M-SHORAD and other directed-energy capabilities like the Indirect Fire Protection Capability-High Energy Laser, or IFPC-HEL, and IFPC-High Power Microwave are all designed to complement the Army’s kinetic air defense capabilities, said Craig Robin, deputy director of the RCCTO’s directed energy project office.
The unique design of the DE M-SHORAD leverages the Stryker’s gas-powered engine to energize its batteries, cooling system, and laser. The self-contained system has enough electricity to address multiple threats at a time before needing a period to recharge, he said.
«There are places where directed energy can provide a significant advantage», he added. «All the bullets are built into the system, so the logistics associated with moving a platform and supplying it requires just gas and parts».
Robin added that directed-energy systems are also more cost-effective from a life cycle perspective, making them a strategic tool to take out low-cost threats like an UAS to save the Army’s kinetic capabilities.
The Army plans to demonstrate the DE M-SHORAD capabilities during Project Convergence 21 (PC 21), where it will participate in a joint and coalition exercise later this year, said Col. Scott McLeod, the program’s manager.
«PC 21 will be a big opportunity for us to show how we can integrate with our systems and demonstrate the capability against other threats», McLeod said.
In July, the prototype proved its abilities during a combat shoot-off at Fort Sill, Oklahoma. During the event, Soldiers faced several realistic scenarios intended to refine future DE M-SHORAD characteristics, as program leads collected extensive data and user feedback to refine the system, McLeod said.
In addition to Project Convergence 21, the DE M-SHORAD development team will make minor adjustments to improve the device’s performance in the coming months, followed by several internal system verifications, he added.
«We are delivering a brand new capability – it is not a modification or an upgrade. It is unlike any other system the Army has fielded to date», McLeod said. «This event was a major step in the prototyping process and an informative waypoint as we move forward with building and delivering a prototype platoon in fiscal year 2022».
