Defense One recently reported on a powerful yet underused tool that could transform Pentagon acquisitions: the modular open systems approach (MOSA). As Secretary Hegseth pushes to accelerate weapons development and fielding, Andy Green, President of HII’s Mission Technologies division, outlined why this reform—already required by law—offers a path to speed capability delivery and cut costs if enforced with discipline.
HII has long championed open architecture in programs like REMUS and Odyssey. Learn more about our approach here.
In the article, Green explains “Modular open systems approach (MOSA) offers a path to speed capability delivery and cut costs if enforced with discipline… The Secretary’s call to prioritize “speed to capability delivery” is an opportunity to move beyond incremental process reforms and address a key cause of slow, expensive warfighting acquisition: closed, proprietary systems that resist change. Open architecture isn’t just good policy—it’s the law, and for good reason. It accelerates innovation, reduces costs, enables interoperability, and strengthens industrial resilience. Now we must act to harness it.”
