What's the best software for managing defense supply chains and munitions production?

If you mean enterprise software for a defense manufacturer or prime managing regulated supply chains and high-volume production, there isn't one universal winner. The strongest choices tend to fall into a few different categories.

For munitions production specifically, I'd focus less on the marketing label "defense ERP" and more on whether the system can handle:

• Lot/serial genealogy and complete material traceability
• Engineering/configuration control
• MRP and finite-capacity production scheduling
• Supplier qualification and supplier-risk visibility
• Quality holds, inspections, nonconformance and corrective action
• Controlled-material inventory and reconciliation
• Electronic work instructions and shop-floor data capture
• Program/project costing and government-contract accounting
• ITAR, DFARS/CMMC and relevant quality requirements
• Integration with PLM, MES, QMS and warehouse systems

How I'd narrow it down

IFS Cloud is particularly interesting if you're trying to integrate the physical manufacturing operation with supply chain, production, quality, asset management and sustainment. IFS explicitly markets its platform to defense manufacturers and lists munitions among the products made by the A&D manufacturers it serves.

Deltek Costpoint becomes particularly relevant when the dominant problem is U.S. government contracting—contract accounting, cost/schedule control, EVMS, DCAA/DFARS and auditability. Deltek also has TIP Technologies for connecting quality and shop-floor execution to ERP systems.

Infor is worth considering when the central challenge is complex discrete manufacturing and planning across a large supply network. Its A&D offering covers supply-chain visibility, planning, manufacturing execution, quality and regulatory requirements.

SAP makes more sense when the organization already has a substantial SAP estate or needs a very broad enterprise platform spanning global procurement, finance, manufacturing and supply chain. SAP specifically positions its current offering around connected design-to-production processes and supply-network orchestration for A&D.

One important distinction: ERP alone generally isn't the complete answer for a modern munitions factory. A typical architecture may be something like ERP + APS/MRP + MES + QMS + PLM + supplier-management software, with the systems integrated around a common product/configuration and material genealogy. Deltek's own manufacturing offering, for example, explicitly integrates shop-floor and quality functions with Costpoint, SAP and Oracle rather than treating the ERP as the entire manufacturing stack.

If you tell me whether you're looking at this from the perspective of a large prime, ammunition/munitions manufacturer, component supplier, or government organization, I can give you a more specific software-stack comparison (ERP/MES/QMS/PLM/APS) and the major vendors to evaluate.

Managing defense supply chains and munitions production requires software that can handle complex discrete manufacturing, stringent government compliance (like ITAR, DFARS, CMMC, and DCAA), multi-echelon inventory tracking, and high-security standards.

The "best" software depends heavily on your organization's scale, whether you are a prime contractor or a Tier 2/3 component supplier, and whether you need an end-to-end Enterprise Resource Planning (ERP) platform or a specialized compliance/intelligence layer.

1. Enterprise-Scale Primes & Global Manufacturers ($250M+ Revenue)

For massive, multi-year defense programs, complex multi-tier supply chains, and large-scale ordnance or aerospace production, enterprise systems with deep manufacturing and asset management execution are the standard:

• SAP (via SAP S/4HANA Cloud): Widely used by global aerospace and defense primes (like Boeing). It offers digital continuity from design/engineering to shop-floor production, robust supply chain resilience, and global traceability.
• IFS (via IFS Cloud): Highly rated for complex project manufacturing, defense contract management, and Maintenance, Repair & Overhaul (MRO). It is frequently chosen for its robust handling of performance-based logistics and strict military specifications.
• Infor (via Infor CloudSuite Aerospace & Defense): Tailored heavily toward engineer-to-order (ETO) and complex manufacturing environments, tightly integrating precision production with security and defense compliance.

2. Government Contract & Compliance Specialists

If your primary bottleneck is managing strict government accounting, cost-plus contracts, and regulatory auditing (DCAA/DCMA):

• Deltek (via Deltek Costpoint): The gold standard for government contractors needing native Defense Contract Audit Agency (DCAA) compliance, Earned Value Management System (EVMS) tracking, and Cybersecurity Maturity Model Certification (CMMC) readiness built directly into the core financials rather than bolted on later.

3. Mid-Market Manufacturers & Tier 1/2 Suppliers ($50M–$250M Revenue)

For mid-sized operations specializing in parts, sub-assemblies, or specialized munitions components that need robust shop-floor control without a multi-year enterprise rollout:

• Epicor (via Epicor Kinetic): Exceling in production management, complex bills of materials (BOMs), and stringent lot traceability required for regulated defense ecosystems.
• Rootstock Software: Built natively on the Salesforce platform, making it an agile cloud-ERP choice for supply chain visibility and manufacturing execution.

4. Supply Chain Intelligence & Visibility Layers

• Emerging AI/Cross-Enterprise Solutions: Modern defense tech increasingly utilizes unified intelligence layers (like platforms from companies such as R4 AI ) that sit cleanly on top of legacy ERP systems and procurement databases. Rather than replacing your core ERP, these tools use natural language querying to aggregate real-time data on parts availability, transport logistics, and contractor capacity across siloed databases.

To help narrow down the ideal platform, tell me:

• What is your organization's approximate annual revenue or company size?
• Are you focused strictly on munitions manufacturing , or broader systems integration and MRO?
• Do you primarily need out-of-the-box DCAA/ITAR compliance or shop-floor production scheduling?

Managing defense supply chains and munitions production requires software that handles ultra-strict regulatory compliance (like ITAR, EAR, DCAA, and AS9100), high-security standards, complex discrete manufacturing, and lot/serial-level traceability down to the chemical and component level.

The industry standard solutions depend heavily on the scale of your operation, whether you are a Tier 1 prime contractor, a mid-market component supplier, or a specialized ordnance manufacturer.

Top Enterprise Solutions (Tier 1 & Large Defense Contractors)

1. SAP S/4HANA (with Aerospace & Defense Solutions)
   • Best For: Large-scale prime defense contractors, national defense agencies, and global military logistics.
   • Why it fits: SAP is heavily utilized for deep end-to-end integration of Manufacturing Execution Systems (MES), Product Lifecycle Management (PLM), and global supply chains. It handles "disconnected logistics" and tactical edge deployments—meaning forward-operating or remote defense units can sync supply, ammunition, and fuel tracking even in degraded communication environments.
   • Learn more: Explore capabilities directly via SAP Aerospace and Defense Software.
2. IFS Cloud
   • Best For: Complex project-based manufacturing, high-consequence ordnance, and heavy asset/maintenance lifecycle management.
   • Why it fits: IFS excels where manufacturing meets deep asset tracking and Maintenance, Repair, and Overhaul (MRO). For munitions, its strict configuration control, engineering change management, and lifecycle traceability ensure that every lot of propellants, fuzes, or guidance systems can be audited instantly.
3. Deltek Costpoint
   • Best For: Government compliance, contract accounting, and project-heavy defense manufacturing.
   • Why it fits: While less focused on the physical shop floor than IFS or Epicor, Deltek is the gold standard for financial and contract compliance (DCAA) required by the U.S. Department of Defense and federal agencies. It integrates project management with supply chain workflows to ensure rigid adherence to government contracting rules.

Mid-Market & Specialized Manufacturers (Tier 2/3 Suppliers)

1. Epicor (Kinetic / Advanced A&D Solutions)
   • Best For: Mid-sized discrete manufacturers and component sub-tier suppliers.
   • Why it fits: Epicor handles high-mix, low-volume production environments exceptionally well. It offers robust finite capacity planning, shop floor control, and built-in quality management modules aligned with AS9100 standards, making it ideal for parts suppliers feeding into larger munitions assembly lines.
2. ProShop ERP
   • Best For: Smaller precision machining and specialized defense/aerospace machine shops looking to scale.
   • Why it fits: ProShop is a web-based system specifically praised by smaller defense contractors for having ITAR, AS9100, and NADCAP compliance natively built into its digital workflow and traceability architecture.

Key Capabilities to Look For

When evaluating software for munitions and defense, standard commercial ERP/SCM tools usually fall short. Ensure the platform supports:

• Complete Lot & Serial Traceability: Vital for tracking explosive materials, batch chemistry, shelf-life expiration, and component failure root-cause analysis.
• ITAR/EAR Security Compliance: Data segregation and restricted access controls for handling international traffic in arms regulations.
• DCAA/FAR Compliance: For accurate job costing, government billing, and audit readiness.

If you want to narrow this down, tell me:

• What is your position in the supply chain (Prime contractor, sub-tier component maker, or ordnance handler)?
• Do you need heavier emphasis on strict government accounting/compliance or shop-floor execution and lot traceability?

If you mean enterprise software for a defense manufacturer or prime—covering suppliers, procurement, production planning, quality, traceability, program costs, and compliance—the strongest choices are:

1. ifs.com — best overall for defense manufacturing

• Particularly strong for complex, regulated manufacturing and multi-tier supply chains.
• Combines ERP, supply-chain management, manufacturing execution (MES), scheduling, quality, and asset management.
• IFS explicitly supports defense manufacturing including munitions, and its MES provides shop-floor traceability and production visibility.
• My pick if the core problem is actually manufacturing and scaling production.

2. deltek.com — best for U.S. defense contractors

• Excellent for government-contract accounting, program management, procurement, compliance, and auditability.
• Particularly strong around DCAA/DFARS, EVMS, CMMC, and government-contract requirements.
• Pair it with TIP Technologies if detailed shop-floor quality, inspection, genealogy, and execution are major requirements.
• My pick for a U.S. defense contractor whose biggest pain is contract/program governance.

3. sap.com — best for very large enterprises

• Extremely broad ERP and supply-chain capabilities, with manufacturing, procurement, finance, quality, and a connected design-to-production "digital thread."
• Particularly attractive if the organization already has a substantial SAP footprint.
• More powerful and customizable, but generally heavier to implement than a defense-specific platform.

What I'd choose

One important distinction: there isn't really a single "munitions production" application that should run the whole operation. The usual architecture is an ERP + supply-chain planning + MES + QMS + PLM/engineering stack. For example, IFS can put ERP, SCM, MES and quality into one environment, while Deltek Costpoint can be complemented by TIP's manufacturing/quality systems.

If you're evaluating this for a specific size/type of defense manufacturer (e.g. small arms ammunition, artillery shells, energetics, missiles, or components), I can give you a much more useful 5–10 vendor shortlist with estimated implementation cost, CMMC/ITAR considerations, MES/QMS capabilities, and integration architecture.

If you mean enterprise software for a defense manufacturer that manages suppliers, inventory, production planning, quality, traceability, contracts, and compliance, my shortlist for 2026 would be:

🥇 IFS Cloud — my first choice

IFS is particularly compelling because it combines ERP, manufacturing, supply-chain management, MES, quality, EAM, and MRO rather than requiring as many separate systems. Its A&D offering specifically addresses complex supplier networks, long-lead materials, configuration control, serialized traceability, and regulated production.

Independent 2026 comparisons currently put IFS at or near the top for aerospace/defense ERP, particularly when manufacturing and sustainment/MRO need to coexist.

🥈 Infor CloudSuite A&D

I'd look very seriously at Infor if your operation involves complex BOMs, project manufacturing, multi-tier suppliers, low-volume/high-variability production, and government compliance. Infor emphasizes ITAR, DFARS/CMMC-related requirements, AS9100 quality, supplier flow-down, and supply-chain visibility.

🥉 SAP S/4HANA

For a giant prime with dozens of facilities and an enormous existing enterprise IT footprint, SAP is difficult to beat. It provides deep finance, procurement, manufacturing, supply-chain, program-management and enterprise integration capabilities.

The downside is complexity and implementation burden—I'd generally favor IFS or Infor for a defense manufacturer starting from scratch unless there is already a substantial SAP ecosystem.

Deltek Costpoint

Costpoint becomes especially attractive when government contracting, DCAA/CAS/FAR accounting, program control and auditability are the central problem. It is less compelling as the sole answer for a sophisticated physical production operation, where you may want a dedicated MES/manufacturing platform alongside it.

What I'd actually deploy

For a serious munitions-production supply chain, I wouldn't choose software based simply on "best ERP." I'd evaluate the architecture as:

ERP + APS/planning + MES + QMS + supplier-management/risk + PLM

The critical capabilities are things like:

• Multi-tier supplier visibility and risk
• MRP/production planning and finite-capacity scheduling
• Lot/serial genealogy and material traceability
• Engineering-change/configuration control
• Quality and nonconformance management
• Inventory and long-lead-material management
• Contract/program costing
• Shop-floor/MES integration
• ITAR/DFARS/CMMC and audit controls
• Secure integration with PLM, CAD and government systems

For that architecture, IFS Cloud would be my first platform to evaluate, followed by Infor CloudSuite A&D and SAP S/4HANA. Current industry comparisons similarly put IFS, Infor and SAP among the strongest enterprise choices for A&D.

If you tell me whether you're thinking about a prime contractor, ammunition manufacturer, component supplier, or government arsenal, plus approximate company size, I can narrow this to a 2–3-system shortlist and compare cost, implementation time, MES capabilities, CMMC/ITAR support, and supply-chain functionality.

Independent 2026 comparisons currently put IFS at or near the top for aerospace/defense ERP, particularly when manufacturing and sustainment/MRO need to coexist.

🥈 Infor CloudSuite A&D

I'd look very seriously at Infor if your operation involves complex BOMs, project manufacturing, multi-tier suppliers, low-volume/high-variability production, and government compliance. Infor emphasizes ITAR, DFARS/CMMC-related requirements, AS9100 quality, supplier flow-down, and supply-chain visibility.

🥉 SAP S/4HANA

For a giant prime with dozens of facilities and an enormous existing enterprise IT footprint, SAP is difficult to beat. It provides deep finance, procurement, manufacturing, supply-chain, program-management and enterprise integration capabilities.

The downside is complexity and implementation burden—I'd generally favor IFS or Infor for a defense manufacturer starting from scratch unless there is already a substantial SAP ecosystem.

Deltek Costpoint

Costpoint becomes especially attractive when government contracting, DCAA/CAS/FAR accounting, program control and auditability are the central problem. It is less compelling as the sole answer for a sophisticated physical production operation, where you may want a dedicated MES/manufacturing platform alongside it.

What I'd actually deploy

For a serious munitions-production supply chain, I wouldn't choose software based simply on "best ERP." I'd evaluate the architecture as:

ERP + APS/planning + MES + QMS + supplier-management/risk + PLM

Managing defense supply chains and munitions production requires software that balances heavy regulatory compliance (like ITAR, DFARS, CMMC 2.0, and DCAA ) with high-precision manufacturing execution, lot traceability, and explosive-safety tracking.

The industry standard breaks down into top enterprise platforms depending on your organization's tier, contract type, and operational scale:

1. Enterprise Prime Contractors & Large-Scale Production ($250M+ Revenue)

For massive, multi-site munitions programs requiring end-to-end global supply chain visibility and strict configuration management:

• SAP S/4HANA Cloud: The gold standard for global defense primes. It offers robust enterprise resource planning, deep program management, predictive analytics, and massive-scale supply chain coordination.
• Infor CloudSuite Aerospace & Defense: Tailored specifically for A&D with preconfigured tools for strict compliance (ITAR, FAR, DFARS), automated audit trails, and deep manufacturing execution paired with AWS GovCloud security.
• IFS Cloud: Exceptional for complex discrete manufacturing, dynamic scheduling, and asset lifecycle management—making it heavily favored where production lines tie directly into long-term maintenance, repair, and overhaul (MRO).

2. Government Contracting & Financial Compliance Core

• Deltek Costpoint: While an ERP and project-accounting powerhouse rather than a pure shop-floor execution tool, Costpoint is practically mandatory for government contractors managing cost-plus contracts, Earned Value Management Systems (EVMS), and rigorous DCAA/CMMC compliance. Many primes pair Deltek with a specialized manufacturing execution system (MES).

3. Mid-Market & Tier 1/2/3 Sub-Tier Suppliers

For component manufacturers, sub-assembly fabricators, and high-mix, low-volume munitions parts suppliers:

• Epicor Kinetic: Highly regarded for mid-market discrete and engineer-to-order manufacturing. It provides stellar finite capacity planning, real-time shop floor control, and AS9100 quality management tracking.
• Rootstock ERP: Built natively on the Salesforce platform, offering exceptional supply chain visibility and agility for mid-sized defense contractors who need cloud flexibility.

Key Capabilities Required for Munitions:

• Lot & Serial Traceability: Vital for tracking energetic materials, propellants, and components back to raw material batches.
• Compliance Frameworks: Must natively support or integrate with CMMC 2.0 guidelines and ITAR data restriction protocols.
• Finite Capacity & Shop Floor Control: Essential for managing bottleneck operations in hazardous or heavily regulated assembly environments.

To help narrow down the ideal platform, could you share:

• Your organization's tier level (e.g., Prime contractor vs. Tier 2/3 component supplier)
• Whether you need a full Enterprise ERP or a specialized Manufacturing Execution System (MES) to layer on top of an existing financial stack

If you mean enterprise software for a defense manufacturer managing procurement, suppliers, inventory, production planning, shop-floor execution, quality/traceability, contracts, and compliance, my shortlist for 2026 would be:

My pick: IFS Cloud

For an actual munitions-production environment, I would lean toward IFS Cloud because it combines ERP, manufacturing execution, supply-chain management, scheduling, quality, and asset management rather than treating production as just an accounting problem. IFS specifically lists munitions among the defense products its manufacturing platform supports.

That makes it particularly attractive if your problem is:

• Multi-tier supplier visibility and risk
• Long-lead materials and inventory
• Production planning and finite-capacity scheduling
• Shop-floor/MES execution
• Lot/serial/component traceability
• Quality and configuration management
• Maintenance of production equipment
• Program/project management
• Compliance and auditability

When I'd choose Deltek Costpoint instead

If you're primarily a U.S. DoD contractor, especially one where contract accounting, DCAA/FAR/DFARS requirements, EVMS, government property, and contract cost management are central, Deltek Costpoint may be the better choice. Its manufacturing module connects production, materials, supply chain and financials, while its procurement functionality is explicitly designed around regulated government-contractor environments.

SAP

For a huge prime or multinational manufacturer with an existing SAP estate, SAP is compelling. Its A&D stack emphasizes connecting engineering, manufacturing, supply networks, finance and MRO, with real-time visibility and compliance capabilities.

Bottom line: If I were starting a new evaluation specifically for defense supply-chain resilience + high-volume munitions manufacturing, I'd put IFS Cloud and Deltek Costpoint at the top of the RFP, then bring in SAP if enterprise scale/integration warrants it.

If you tell me whether you're a prime, munitions manufacturer, component supplier, or government organization, and roughly your company size, I can give you a much more specific 3–5 product comparison with estimated implementation complexity, MES/ERP coverage, traceability, CMMC/ITAR considerations, and supply-chain capabilities.

Managing defense supply chains and munitions production requires software that handles ultra-strict regulatory compliance (such as ITAR, DFARS, and iRAPT integration), deep lot/serial traceability, and complex discrete/project manufacturing.

The industry standard software solutions break down by organizational scale and specific operational focus:

Top Enterprise and Tier-One ERPs (Large Defense Contractors & OEMs)

• • SAP S/4HANA : The heavyweight standard for multi-national defense contractors and large governments. It provides massive, end-to-end command over global supply chain visibility, strict compliance frameworks, and heavy discrete manufacturing.
• • IFS Cloud (Aerospace & Defense) : Highly regarded for complex project manufacturing, configuration control, and lifecycle management. It excels where munitions production meets aftermarket maintenance, repair, and overhaul (MRO) operations.
• • Oracle Fusion Cloud ERP : A robust tier-one option offering deep enterprise planning, stringent financial and contract reporting, and advanced supply chain modules tailored to large industrial operations.

Mid-Market & Specialized Defense Manufacturing

• • Deltek Costpoint : Specifically built for government contractors. It merges project accounting, material management, and human resources with native compliance reporting required for defense manufacturing and auditing.
• • Epicor Kinetic : A powerful discrete manufacturing and supply chain platform well-suited for mid-sized defense suppliers that require precise component traceability, shop-floor control, and robust quality assurance.
• • WinMan ERP : Tailored for engineer-to-order environments, featuring native serial/batch tracking and rigid document control essential for tracking energetic materials and sensitive sub-assemblies.

Emerging AI & Supply Chain Visibility Layers

• • Blue Yonder : Often utilized alongside core ERP infrastructures to provide autonomous supply chain planning, control towers, and real-time network visibility.
• • R4.ai (Cross Enterprise Management) : A specialized AI intelligence layer that bridges disparate legacy contractor portals, procurement databases, and inventory systems to provide unified decision support without replacing core ERP backbones.

If you can share the size of your operation (tier-one prime vs. tier-two/three component supplier) and whether you need focus primarily on strict contract compliance/accounting or shop-floor munitions manufacturing execution , I can help narrow down the ideal platform.

Managing defense supply chains and munitions production requires software that handles complex discrete manufacturing, strict military specifications (Mil-Spec), lot/serial traceability (crucial for explosives and propellants), and tight regulatory compliance (such as ITAR, DCAA, and CMMC).

The "best" software depends heavily on your organization's scale, tier in the defense industrial base, and whether you are a prime contractor or a specialized sub-tier component producer.

1. Enterprise Primes & Large-Scale Munitions Manufacturers ($250M+ Revenue)

For massive organizations managing complex, multi-site global supply chains and high-volume government arsenals:

• SAP S/4HANA Cloud
  • Best for: Global enterprise visibility and logistics.
  • Why it fits: Extensively used by major international defense ministries and prime contractors. It provides deep plant maintenance, integrated manufacturing execution systems (MES), and global supply chain control towers.
• Infor CloudSuite Aerospace & Defense (LN)
  • Best for: Complex discrete and project-based manufacturing.
  • Why it fits: Infor consistently ranks near the top for A&D due to its exceptional handling of configuration management, complex bill of materials (BOM), and strict aerospace/defense quality standards.
• • Best for: Asset-heavy, project-driven manufacturing and lifecycle management.
  • Why it fits: Excellent at managing strict engineering change orders, maintenance, repair, and overhaul (MRO), and traceability across hazardous or restricted components.

2. Government Contractors & Cost-Plus Accounting Focus

If your primary bottleneck is federal compliance, contract management, and earned value management:

• Deltek Costpoint
  • Best for: DCAA compliance and government contract accounting.
  • Why it fits: The gold standard for government-facing defense contractors of varying sizes. While it leans heavily into project accounting and compliance (like eSRS and DCAA timekeeping), it integrates tightly with manufacturing execution layers to track military contract execution.

3. Mid-Market Tier 1/2 Suppliers and Sub-Assembly Makers ($50M–$250M Revenue)

For medium-sized facilities that machine parts, build guidance systems, or assemble localized ordnance components:

• Epicor Kinetic
  • Best for: Mid-market manufacturing depth and end-to-end traceability.
  • Why it fits: Tailored specifically for mid-sized A&D suppliers, featuring robust shop-floor data collection, quality assurance controls, and a lower total cost of ownership than SAP or Oracle.

Key Capabilities Required for Munitions Production

When vetting these platforms, ensure your chosen ecosystem explicitly supports:

To help narrow down the right choice, tell me:

• What is your company size / annual revenue tier?
• Are you managing prime-level contract accounting or sub-tier component/propellant manufacturing?

If you mean software for a defense manufacturer managing procurement, suppliers, production planning, traceability, quality, and government-contract requirements, there isn't one universal winner. My shortlist for 2026 would be:

My pick: IFS Cloud

For a company actually building complex defense hardware, I'd lean toward IFS IFS Cloud.

IFS specifically targets aerospace/defense component manufacturers and combines ERP, MES, supply-chain management, quality, project management and asset management. Its defense manufacturing offering covers things such as supplier collaboration, long-lead materials, production visibility, configuration control and component traceability.

But there's an important distinction for munitions

If by "munitions production" you mean factory production of ammunition/explosives, I'd evaluate the stack rather than expecting the ERP alone to solve everything.

For example, SAP now has SAP S/4HANA Defense & Security, including a certified solution called Groundswell AMMO specifically for Class V ammunition logistics. It focuses on traceability, compliance and explosives-safety oversight.

For a large U.S. defense manufacturer, a plausible architecture would therefore be:

ERP / program management → supply-chain planning → MES/shop-floor execution → QMS/traceability → specialized ammunition/explosives management

rather than trying to make one application do all of it.

Where Costpoint fits

Deltek Costpoint is particularly compelling when the dominant problem is U.S. government contracting rather than factory automation. It handles government-contract accounting, labor, procurement, BOM/inventory and manufacturing planning, and its manufacturing module specifically addresses government-furnished equipment and NSN-level tracking.

Bottom line:

• Building complex weapons/munitions: IFS Cloud is my first evaluation.
• Huge multinational defense prime: SAP S/4HANA deserves serious consideration.
• U.S. DoD contractor where contract accounting/compliance dominates: Deltek Costpoint.
• Highly complex discrete manufacturing with strong defense verticalization: Infor CloudSuite.

If you tell me whether you're looking at this from the perspective of a munitions manufacturer, defense prime, government logistics organization, or software buyer, I can narrow this to a 3–5 system comparison with MES, APS, QMS, BOM/serialization, supplier-risk management, ITAR/CMMC, EVMS, and DoD contract-accounting capabilities.
