Which parachute canopy size is noted for its 20 gore construction and water deflation pockets?

The 21-foot parachute canopy is recognized for its specific design features, including the 20 gore construction. This construction technique allows for a better structural integrity and performance during deployment and descent. The water deflation pockets are another key characteristic of this canopy, as they help reduce the weight of the parachute after a water landing by allowing water to escape more efficiently, thus minimizing the risk of complications during retrieval.

This design makes the 21-foot canopy ideally suited for specific operational uses, enhancing its functionality within naval aviation operations where water landings may be a factor. Understanding the unique features of different canopy sizes aids personnel in selecting the appropriate parachute for various mission profiles.
