But additional investments in MOSA upfront could help the Army successfully integrate capability at a lower cost by continuously boosting competition, a recent Center for Strategic and Budgetary Assessments report found.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In creating an \u201copen ecosystem,\u201d MOSA would \u201chelp avoid costly and time-consuming redesign to accommodate both hardware and software upgrades by making standards and interfaces readily available,\u201d the report said.<\/p>\n\n\n\t<aside class=\"smg-interstitial-link wp-block-smg-interstitial-link\">\n\t\t<a href=\"https:\/\/one.sightlinemg.com\/c4isrnet\/digital-show-dailies\/ausa-digital-show-dailies\/2021\/10\/11\/sosa-consortium-unveils-first-standards-for-military-sensor-technologies\/\" class=\"smg-interstitial-link__inner\">\n\t\t\t\t\t\t\t<div class=\"smg-interstitial-link__media\">\n\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"200\" src=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/6707767.jpg.jpg?w=300\" class=\"smg-interstitial-link__image wp-post-image\" alt=\"\" \/>\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"smg-interstitial-link__content\">\n\t\t\t\t<span class=\"smg-interstitial-link__kicker\">Related<\/span>\n\t\t\t\t<h3 class=\"smg-interstitial-link__title\">SOSA consortium unveils first standards for military sensor technologies<\/h3>\n\t\t\t\t\t\t\t\t\t<p class=\"smg-interstitial-link__excerpt\">The standards are intended to drive open architectures for military systems.<\/p>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/a>\n\t<\/aside>\n\t\n\n\n<p class=\"wp-block-paragraph\">MOSA could also reduce long-term operations and sustainment costs, which often account for much more of a program\u2019s cost \u2014 roughly 70 percent \u2014 over its life cycle, the report found.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">MOSA is not \u201ca complex thing to understand,\u201d Brig. Gen. Robert Barrie, the service\u2019s program executive officer for aviation, said in an interview with Defense News ahead of the Association of the U.S. Army\u2019s annual conference.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe thought is that we want to invest in capability once and then we want to be able to apply that capability very affordably across multiple platforms,\u201d he continued. \u201cTo date, we have been immensely challenged in our ability to do that.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Maj. Gen. Wally Rugen, who is in charge of Army Future Vertical Lift modernization, said during the same interview that the \u201capproach gives us an opportunity to address the real critical path on affordability.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Barrie said an example of how MOSA might be used is that the Army would require a vendor to modularize the design of an aircraft engine so it can perform maintenance or replace individual modules without replacing the entire engine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThis leads to both significant cost savings and an increased readiness of our aircraft,\u201d he said, noting those are two of the program office\u2019s MOSA objectives.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Army is also requiring adherence to government-defined interfaces and use of identified consensus-based standards, according to Barrie. This is meant to allow the service to better manage integration and modification to the platforms and systems \u201cso that they are more cost effective, result in quicker tech insertions and reduce supply chain risks.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Developing a capability once and applying it across the fleet will also schedule pressure, he added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Army has been working on MOSA for over a decade, Rugen said. Much of that was during the Army\u2019s Joint Multi-Role Technology Demonstration, in which two competitive demonstrator aircraft flew over the course of several years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cI don\u2019t want to oversell it, but we\u2019ve had some initial prototyping out at Project Convergence and Edge 21 to understand some of the use cases within MOSA,\u201d Rugen said, \u201cThey\u2019ve been blunt instruments, but we\u2019ve moved the ball and then that\u2019s fed back into the architecture working group\u201d within PEO Aviation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Project Convergence is an annual assessment of how emerging technology and tactics, techniques and procedures can come together to defeat advanced adversaries with high-end capabilities in a future fight. The exercise is kicking off this month. Edge 21, conducted in May, evaluated capabilities for the aerial tier in preparation for Project Convergence.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Army has looked at past failures with MOSA. Barrie said the problems were often related to the service\u2019s lack of a good governance process to manage who determines the systems and architecture used for each aircraft.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cWe didn\u2019t have policy written both inside the PEO and the Army that said these are the guiding principles of an open system approach and here\u2019s how you will, from a policy perspective, develop these things,\u201d he said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Army also didn\u2019t align its investments properly, and requirements were not written to address an open systems approach, he noted.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">PEO Aviation has established a MOSA transformation office as one way to stay organized in the process. Before any investment in a program is made on any capability on a platform now, it gets run through the office to determine if it meets MOSA criteria, Barrie said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIf it doesn\u2019t, why?\u201d he added. \u201cAnd we can bring it forward and make recommendations about how we can do it in a better way.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An architecture collaboration working group, consisting of over 700 participants across academia and industry, is working with the FVL modernization team to ensure it\u2019s moving in the right direction on MOSA.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Army would define MOSA success as an architecture that gives the service the ability to upgrade its systems at the pace of technology, Rugen said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cCommanders will be able to rapidly update critical capabilities creating multiple dilemmas for our adversaries,\u201d he said. \u201cMOSA saves time and lowers future operations and support costs.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Army has struggled to produce new
