China Lake grenade launcher (often called the “China Lake pump”) is a U.S.-made pump-action 40×46mm grenade launcher developed for Naval Special Warfare use during the Vietnam War. It uses a tubular magazine holding three grenades, plus one in the chamber, allowing four shots in rapid succession before reloading. It is best known for its very limited production and its association with U.S. Navy SEAL teams as a short-lived attempt to provide repeating 40mm firepower.

HISTORY

The weapon was developed at the Naval Weapons Center/Naval Air Weapons Station China Lake as a response to the limitations of single-shot launchers like the M79 and XM148 and the reliability problems of early repeating designs such as the T148E1. China Lake engineers applied pump-action shotgun concepts to a 40mm launcher, producing a compact repeating system that retained M79-like range and accuracy while greatly increasing immediate volume of fire. Reports from the period and later accounts describe it as well-received by some SEAL users and effective with standard HE-fragmentation ammunition in Vietnam.

Sources differ on total production, with estimates commonly ranging from the mid-teens to a few dozen; later Navy-record checks cited by SEAL historian Kevin Dockery are often reported as confirming 22 completed guns. The launcher was never formally standardized with an official U.S. designation, and the names “NATIC” and “EX-41” are frequently described as mistaken or later, unrelated labels. Surviving originals are scarce, with documented examples in museum collections including the National Navy UDT-SEAL Museum and Vietnam’s War Remnants Museum, while others remain in U.S. Navy custody.
