This poster features an amazing underwater firearm developed in during the Cold War.
The Lancejet underwater rocket pistol was developed in the early 1960s by MBAssociates for use by US combat divers. Lancejets themselves were rocket-propelled cartridges in varying calibers and diameters, which were developed with a wide range of applications in mind.
The final design, patented in June 1967, fired a 10mm tungsten-carbide Lancejet which could also be loaded with a small explosive warhead. It doesn’t appear that the Navy ever purchased the Lancejets, and they became one of many unique weapons designs that have nearly disappeared from history.
Now available is the illustration accompanying the original patent application for the Lancejet pistol, described here as an "Underwater Weapon" by inventors Arthur T. Biehl and Robert Mainhardt. The patent application was submitted in April 1965, and awarded in June 1967.
These posters are 11" by 17" and printed on heavy 65-lb paper for a memorable texture and durability. All printed posters are sourced from a small, local family-owned business. Each poster is shipped in a 12" x 2" cardboard shipping tube.
