Easily Integrated and Adaptable

Future Long-Range Assault Aircraft (FLRAA) and future variants enables Army Aviation, the joint forces and international partners to achieve adaptability, commonality, interoperability, total lifecycle affordability, and most importantly, overmatch.

We're able to deliver something that meets the needs of the customer, is unique in terms of what industry's been able to provide in the past and really gives them the keys to manage their mission systems going forward.

MOSA Benefits

Reduce cost and schedule

Costly requalification avoided through digital isolation of the mission systems from flight critical avionics.

Rapid technology integration

Rapid technology insertion enabled by an open architecture, modular design. The system enables better interoperability and isolation of the Air Vehicle / Mission System for rapid, cost-effective upgrades upon mature open standards, such as FACE, HOST, SOSA and more.

Enhanced lifecycle management 

Bell’s open architecture digital backbone ensures an adaptability, reconfigurable and interoperable weapon system has the right capability for the mission when needed.
