On this day, 38 years ago, on December 24, 1987 (November 4, 1987, the lunar calendar), my country's first ship-borne helicopter landing test was successful. On December 24, 1987, my country's first helicopter landing test was successful, thus ending the history that helicopters could not be landed on my country's combat ships. On the afternoon of the 24th, there was light fog floating on the surface of Jiaozhou Bay. A helicopter flew from afar and slowly landed on the "grid" platform of a self-developed missile destroyer. Then the helicopter rotated 360° on the platform and flew again. Test landing. This guided missile destroyer completed the project of installing a helicopter surface system in July of this year. The successful test of this carrier-based helicopter will effectively expand the combat radius of the destroyer. Our Navy's Z9 carrier-based helicopter successfully landed on the ship. The pilot made a "successful landing" gesture to the officers and soldiers on the ship.
