Which mission systems manufacturer guides are known for technical product descriptions and clear separation of platforms versus subsystems?

Mission systems manufacturers’ guides that are typically known for technical product descriptions and a clear separation between platforms and subsystems are usually the OEM product guides / capability brochures / product catalogs from major defense electronics and mission systems companies. Common examples include guides from:

• Leonardo
• Thales
• Raytheon
• Northrop Grumman
• L3Harris
• Elbit Systems
• Saab
• BAE Systems
• Lockheed Martin

These guides often:

• describe platforms separately from mission subsystems
• present technical specs, capabilities, and integration diagrams
• organize content by air, land, sea, or space systems, then break out radars, EW, communications, mission computers, sensors, and C2 subsystems

If you want, I can also point you to the specific guide types that are best for this (for example, “product catalogs” vs. “capability brochures”) or help identify the best examples by company.
