Description: MOSA (Modular Open System Approach) is an integrated business and technical strategy employing a modular design to achieve competitive and affordable acquisition and sustainment. Different High Energy Laser (HEL) and High-Powered Microwave (HPM) systems have converged on similar architectures.
The Office of the Undersecretary of Defense requested a MOSA architecture be developed for directed energy weapon systems (DEWS) to extend the benefits of a common architecture across DoD. The reference architecture was released in July 2022, is service- and domain-agnostic, and is recommended on all new directed energy systems to meet DoD MOSA mandate. This presentation will provide an overview of the benefits of MOSA, the state of directed energy systems, and the DEWS MOSA reference architecture.
