The China Lake pump-action grenade launcher or NATIC is a pump-action grenade launcher that was developed by the Special Projects Division of the Naval Air Weapons Station China Lake, which provided equipment to United States Navy SEALs.

Since it was made on an ad hoc basis for special operations forces, it was not formally adopted and has no official military designation.

In 2003, they achieved a breakthrough and were able to convince fellow writer and firearms enthusiast Captain Monty Mendenhall to finance their research effort.

The CSG/Trident China Lake launchers have increased reliability and improved cycling of action compared to the original.

[citation needed] Manufacturing metals were upgraded with improved hardness treatments and metallurgy since the original China Lake development with both the Airtronic/Trident and CSG/Trident launchers.

[citation needed] In July 2007, Airtronic USA announced that they were entering large-scale production with an initial order of 500 units for US military forces.

This announcement occurred simultaneously with a demonstration of the CSG/Trident China Lake launcher in an episode of the popular military technology program, "Weaponology".

From 2007-2009 contractor and manufacturer Airtronic USA invested over two million dollars with Trident for a contract to reproduce the China Lake Launcher's original design and a more modular design (information provided by Marriellen Kett, president of Airtronic USA).

These improvements include a M203 handguard, M4 carbine-style collapsible stock and barrel with a top Picatinny rail for accessories, and extended the magazine tube to fit four grenades plus one in the chamber.

The nine CSG/Trident patented contract China Lake launchers are transferable as a Destructive Device in the United States.

[citation needed] All CSG/Trident China Lake Grenade Launchers remaining in registry can be considered of extreme rarity.
