MTN69 Inflatable Low-Pressure Shelter

The Low-Pressure Shelter 4, or LPS 4, is a military tent designed for use in extreme environments. It was developed in the 1980s by the United States Army Natick Soldier Research, Development and Engineering Center (NSRDEC) as a replacement for the aging Shelter Half system. The LPS 4 utilizes a unique low-pressure air beam structure to support the tent, making it easy to set up and highly resistant to wind and snow. It has been used in various military operations around the world and has proven to be a reliable and effective shelter option for soldiers in extreme weather conditions.
