Compare 14 defense and aerospace IT consulting partners delivering CMMC 2.0 Level 2 and Level 3 readiness across primes and the supplier base, the ITAR and EAR export-control programmes for technical data, the secure-by-design mission-systems and digital-engineering delivery aligned to MOSA and OMS standards, the ERP and PLM programmes across SAP, Oracle, Siemens Teamcenter, and Dassault 3DEXPERIENCE for tier-one suppliers, the supply-chain illumination and counterfeit-parts controls under DFARS 252.246, the FedRAMP High and IL5 cloud-baseline programmes for DoD workloads, the obsolescence and DMSMS management for long-life platforms, and the digital-thread and model-based-systems-engineering programmes that connect requirements to operations. Listings cover global defense-and-aerospace SI practices, federal-systems integrators, India-heritage SI defense units, and the boutique CMMC and export-control specialists. No partner pays for placement on this directory.
Defense and aerospace engagements break into four typical workstreams. Compliance and security, where the partner runs the CMMC 2.0 readiness across Level 1, Level 2, and Level 3 expectations, designs the enclave architecture for Controlled Unclassified Information (CUI) on Microsoft GCC High, AWS GovCloud, or sovereign-cloud equivalents, builds the ITAR and EAR export-control controls for technical data, and engineers the supply-chain illumination and counterfeit-parts controls under DFARS 252.246. Mission systems and digital engineering, where the partner delivers the secure-by-design platform programmes aligned to MOSA, OMS, and FACE standards, builds the model-based-systems-engineering pipelines with Cameo, Capella, or Rational Rhapsody, integrates with the digital-thread layer in Teamcenter or 3DEXPERIENCE, and engineers the simulation-and-test environments for the platform lifecycle. ERP, PLM, and supply chain, where the partner stands up SAP, Oracle, or Dynamics 365 for the prime or tier-one supplier, integrates with Siemens Teamcenter or Dassault 3DEXPERIENCE for PLM, builds the supplier-portal and supply-chain illumination layer, and engineers the obsolescence and DMSMS management for long-life platforms. Cloud and infrastructure, where the partner builds the FedRAMP Moderate, FedRAMP High, or IL5 cloud baseline for DoD workloads, deploys the secure DevSecOps pipelines aligned to Platform One or alternative DoD reference architectures, and operationalises continuous-monitoring under the OSCAL framework.
Three procurement archetypes recur. Federal systems integrators (Leidos, SAIC, Booz Allen, CACI, CGI) lead at the DoD, intelligence community, and federal civilian customer; their advantage is cleared workforce, security infrastructure, and decades of program-of-record delivery, though the cost basis is high and the operating model is calibrated for government rather than commercial work. Big Four and global SIs (Deloitte, KPMG, Accenture Federal, Capgemini, Eviden) lead at defense primes (Lockheed, Boeing, RTX, BAE, Airbus, Thales) and at the program-management or ERP layer where commercial discipline matters; their advantage is the cross-industry capability and the prime-supplier governance, though deep defense-specific engineering is typically delivered through partner pods or boutiques. Defense-specific boutiques (Redhorse, Summit 7) and India-heritage SIs (TCS, LTIMindtree) lead on the focused engineering programmes - CMMC at the supplier base, engineering-services factories for primes, and the migration of legacy enclaves at predictable cost. Friction point: defense and aerospace IT programmes routinely under-invest in cleared-personnel staffing planning, with the result that programme schedules slip because the cleared workforce was assumed available; clearance-sponsored hiring runs 6-18 months and is the single largest schedule risk on classified-adjacent work.
