Which 781 version is used for COMSEC material installed on the aircraft?

• A. 781D
• B. 781A
• C. 781B
• D. 781C

Answer: (C)

The way this is documented uses a family of 781 forms where each revision signals a specific category of material and its handling. COMSEC material, due to its security sensitivity, requires the version that covers cryptographic material installed on aircraft. That designation is 781B. Using this particular revision ensures the proper documentation, accountability, and procedures for secure material handling—from provisioning to installation and eventual disposition—are followed in line with 00-20-1 requirements. Other revisions correspond to different kinds of equipment or documentation workflows, so they don’t meet the COMSEC installation needs.
