During development and the procurement of UHF radios, military planners did not require features to secure communications for aircraft and helicopters from White Tape Trk 1 - DJ Guy - Basf Ferro until the post- Vietnam War era.

Progress in electronics in the s reached a point where anyone with an inexpensive radio frequency scanner or receiver set could intercept military communications. Once the target frequencies were identified, radio frequency jamming could easily be employed to degrade or completely disable communications. Engineers recognized that newer aircraft radios already included all-channel frequency synthesizers along with keyboards and displays for data entry.

The only other system requirements to achieve the desired anti-jam functionality were an accurate clock for timed synchronization and a microprocessor to add frequency hopping to existing radios. A word of II - Swefn - Halve day is a transmission security variable that consists of six segments of six digits each. The latter features more complex frequency hopping.
