Lockheed Martin Achieves First Light in Latest Laser Lab Demonstration

Lockheed Martin’s 50 kW-class DEIMOS system is a ruggedized, tactical laser weapon system that can be integrated into the Stryker combat vehicle to deliver robust directed energy capability to the U.S. Army’s challenging Maneuver-SHort Range Air Defense (M-SHORAD) mission.

«The 50 kW-class laser weapon system brings another critical piece to help ensure the U.S. Army has a layered air defense capability», said Rick Cordaro, vice president, Lockheed Martin Advanced Product Solutions. «DEIMOS has been tailored from our prior laser weapon successes to affordably meet the Army’s larger modernization strategy for air and missile defense and to improve mission success with 21st Century Security solutions».

 

Why It Matters

Lockheed Martin’s DEIMOS first light demonstration is a crucial milestone along the path to helping the Army perform its DE M-SHORAD mission, which is intended to deliver a maneuverable laser system capable of negating unmanned aerial systems, rotary-wing aircraft and rockets, artillery and mortars.

First light measures the expected beam quality of the system while testing end-to-end performance of our game-changing, low-cost Spectral Beam Combination (SBC) architecture. The key benefit of the company’s SBC is that power can be scaled while retaining the excellent beam quality of the individual fiber lasers.

In 2022, Lockheed Martin demonstrated Layered Laser Defense (LLD) capability by defeating two surrogate cruise missiles at tactically relevant ranges. This LLD capability:

  • Shares many common elements with the DEIMOS system architecture, such as allowing for a single operator to engage and destroy SHORAD targets.
  • Can be seamlessly integrated into various platforms.
  • Can fit on tactical platforms such as a Stryker vehicle because it was designed with constraints in terms of Size, Weight and Power (SWaP).

 

What’s Next

Utilizing a philosophy of «build a little, test a little, learn a lot», Lockheed Martin will expand the DEIMOS test program in 2023, culminating with field integration tests in 2024. This thorough approach is designed to reduce risk, to enable soldier touchpoints and to provide proof points of compelling mission capabilities.

The Army’s Rapid Capabilities and Critical Technologies Office (RCCTO) is leading the DE M-SHORAD prototyping effort and is expected to transition the program to the Program Executive Office (PEO) Missiles & Space in 2024.

GPS III Space Vehicle 06 (GPS III SV06) launched from Cape Canaveral Space Force Station, Florida, aboard a SpaceX Falcon 9 rocket at 7:24 a.m. EST on January 18, 2023. About 83 minutes after liftoff, U.S. Space Force and Lockheed Martin engineers at the company’s Denver Launch & Checkout Operations Center confirmed signal acquisition of GPS III SV06 and now have the space vehicle «flying» under their control.

GPS III SV06 is the 25th Military-Code satellite introduced to the constellation. The satellite will provide advanced technology to aide Space Force operators in their mission by providing Positioning, Navigation and Timing (PNT) data to military and civil users worldwide.

«Lockheed Martin is incredibly proud to support the Space Force’s GPS team as it continues to add world-class capabilities that underpin U.S. national security with enhanced performance and accuracy», said Andre Trotter, Lockheed Martin vice president for Navigation Systems. «With the last GPS III satellite complete and ready to launch, production of the first GPS IIIF vehicle is underway».

GPS is a satellite-based radio navigation system that delivers the gold standard in PNT services to America’s military, U.S. allies and civil users. The satellites serve as a crucial technological foundation for internet, financial, transportation and agricultural operations, with more than 4 billion users depending on the PNT signals.

GPS III vehicles provide three times greater accuracy and eight times greater anti-jamming capability over existing satellites in the constellation. To better address mission needs and emerging threats, Lockheed Martin intentionally created GPS III with a modular design, allowing new technology and capabilities to be added in the future.

Lockheed Martin has completed production on its original GPS III SV1-10 contract, with the Space Force declaring SV10 Available for Launch on December 8, 2022. GPS III SV06 will soon join SV01-05 in orbit. GPS III SV07-10 are completed and in storage at the company’s facility waiting for the U.S. Space Force to call them up for launch.

Lockheed Martin is also designing and building the GPS III Follow On (GPS IIIF) for the Space Force, which will feature even more innovative capabilities than its predecessors. GPS IIIF satellites will feature an accuracy-enhancing laser retroreflector array, a new search and rescue payload, a fully digital navigation payload and more next-generation technology. In November 2022, Space Systems Command announced it exercised the third production option valued at approximately $744 million for the procurement of three additional GPS IIIF satellites from Lockheed Martin, meaning the company is now contracted to build SV11-20.

Building from existing U.S. Navy missile and launcher systems, the MRC provides a fires capability that has not existed in the U.S. Army since the implementation of the Intermediate Nuclear Forces (INF) treaty in 1987. Answering the call to the Army’s No. 1 modernization priority, Long-Range Precision Fires, the MRC can defeat a variety of mid-range targets.

«The MRC rapidly progressed from a blank piece of paper in July 2020, to the Soldiers’ hands in just over two years. The Rapid Capabilities and Critical Technologies Office (RCCTO) team, as well as our joint service and industry partners, delivered this hardware so Soldiers can begin training as quickly as possible», said Lieutenant General Robert Rasch, Director of the Army RCCTO.

Initial hardware delivery occurred with ongoing support planned through December 2022 in preparation for training to begin after the holidays. The delivery includes a complete MRC ground equipment and reload capability, which comprises a battery operations center, four launchers, prime movers, and modified trailers.

The MRC achieves operational capability in fiscal year 2023 upon completion of system testing, training, and delivery of the missiles. Delivering the ground hardware first allows the Soldiers to train on the equipment, create doctrine for the system, and develop tactics, techniques, and procedures.

The MRC Project Office works closely with the Soldiers and Sailors who benefit from this system via embedded Soldier-Sailor Centered Design Events. These events provided critical user feedback throughout the design process and ensured Soldiers and Sailors were at the center of this effort.

In executing the mid-range fires system and testing, the Army continues to work in close coordination with its joint service and agency partners.
