t he monitor news The Office of Naval Research (ONR) has issued a Broad Agency Announcement (BAA) for design, development and demonstration of a solid-state, high-power Laser Weapon System Demonstrator (LWSD). The overall goal of the project is to provide a laser weapon system capable of engaging and defeating multiple threat targets with performance characteristics significantly improved over current and previous systems. According to the BAA, ONR believes that substantial improvements in laser weapon system lethality can be achieved through maturation and optimization of a variety of system characteristics, including increased Solid-State Laser (SSL) power. "Government estimates indicate that systems with laser power of 100-150 kW may be supportable using ship power and cooling." In fact, the BAA notes that recent advancements in the power and durability of commercially available SSL technologies enabled the Navy to execute a quick-reaction effort and operationally field a prototype SSL weapon, know as the Laser Weapon System (LaWS) onboard the USS Ponce last summer, where it has since been undergoing testing and demonstration in the Persian Gulf. The LaWS is being evaluated onboard the USS Ponce in the Persian Gulf. Other potential advances in beam quality, beam director architecture, and other physical and optical aspects of the laser, beam director, and system design, are also identified as achievable, as well as improvements in duty cycle, operability, and maintainability. The program is targeting a Technology Readiness Level (TRL) of 6 for the system in order to support the Navy's potential consideration of a Program of Record (PoR) milestone decision. The BAA calls for "fully-integrated system-level proposals for the LWSD," stating that "proposals that only address partial solutions or component-level technologies will not be considered for award." The LWSD will consist of a performer-supplied Tactical Laser Core Module (TLCM) that will include "at a minimum: a high power SSL subsystem; a beam director subsystem (including accommodation for Mission Specific Modules (MSMs); a targeting and tracking subsystem; fire control subsystem; and the necessary power or cooling subsystems to address interface or capacity issues that might be presented by the available ship utilities." The program is to be organized around a three-phased acquisition structure, with an overall 30-month timeline from contract award to project completion with at-sea testing. Phase I will include "development and refinement of the TLCM design package and risk reduction efforts from System Requirements Review (SRR) through Preliminary Design Review (PDR), completing after the Critical Design Review (CDR)." Phase II addresses system fabrication, landbased testing and demonstrator delivery; while Phase III covers installation and sea-based testing. Ultimately, the LWSD will be installed aboard a Navy test ship for at-sea testing and demonstrations. There, it will be "operated from the ship to execute live-fire engagements in day and night conditions under operationally derived test scenarios consistent with ship self-defense missions, including countering threats from adversary Fast Attack Craft/Fast In-Shore Attack Craft (FAC/FIAC), Unmanned Aerial Vehicles (UAV), and sensor systems used for Intelligence, Surveillance, and Reconnaissance (ISR)." Though the program's current funding and timeline only support testing on the Navy's Self Defense Test Ship (SDTS) USS Paul Foster, the BAA states that design approaches should address the possibility of subsequent installation on a DDG-51 FLT IIA class destroyer with minimal modifications and cost.
