Challenges in the Market

• Complex Integration Across Heterogeneous Platforms And Legacy Systems
  Open architectures must bridge legacy proprietary systems, multiple vendors, and diverse protocols. Integration requires extensive testing, validation, and customization. Platform power, space, and cooling constraints add complexity. Cross-domain data models and middleware translation layers must be developed. Coordination across stakeholders increases program risk. This integration burden extends timelines and increases cost. Engineering expertise is concentrated among a few integrators. This challenge remains a significant barrier.

• Certification, Safety, And Interoperability Accreditation Burden
  Open systems must meet stringent defense safety and interoperability standards. Certification cycles are long and resource intensive. Accreditation processes demand thorough testing across mission phases. Coalition interoperability adds layers of compliance complexity. Mistakes in certification can delay fielding and affect credibility. This challenge extends acquisition timelines and increases cost. Sustaining multiple certification baselines compounds effort. This remains a material inhibitor for new vendors and capabilities.

• Cybersecurity And Electromagnetic Warfare Vulnerabilities
  Open architectures introduce larger attack surfaces through standardized interfaces. Software vulnerabilities can compromise mission data integrity. Rigorous cybersecurity hardening is required. EW threats can exploit open networking layers and middleware. Secure update mechanisms and authentication are essential. Testing for resilience against both cyber and EW threats is demanding. Supply chain assurance adds complexity. This challenge increases lifecycle support costs and operational risk.
