The Checker is a multi-purpose UAV (Unmanned Aerial Vehicle) developed by the American firm Northrop. Its primary purpose was to serve as an unmanned target drone for training exercises. This UAV is equipped with a Williams turbojet engine, capable of developing 82 kgf of thrust.
Design and Technical Specifications
For takeoff, the Checker utilized two rocket boosters suspended under its wings. Its control was managed via radio commands from the ground, ensuring precise operation during its missions.
Operational Use in the Yom Kippur War
Several similar UAVs were employed by the Israeli Army during the so-called Yom Kippur War, where they were assigned the code designation “Telem.” These UAVs were used for detecting enemy air defense targets. For these purposes, the Telem was initially equipped with a photographic camera.
Post-War Upgrades and Evolution
Following the conclusion of the war, the UAVs underwent significant modernization. The original photographic cameras were replaced with video cameras, enhancing their reconnaissance and surveillance capabilities for future operations.
