Joint Service Lightweight Integrated Suit Technology

The Joint Service Lightweight Integrated Suit Technology or JSLIST consists of a two piece garment designed to replace the Navy's existing Chemical Protection Overgarment (CPO). The JSLIST garment offers a number of advantages over the Navy' s current CPO. The JSLIST garment features state-of-the-art chemical protective lining technology which provides increased chemical protection while allowing more mobility for the wearer, and can be laundered up to three times. The CPO suit contains a charcoal impregnated lining. During wear, this lining is leached onto the wearer causing inner garments to become coated with charcoal dust. The CPO suit would disintegrate if laundered.

In 1993 the U.S. Marine Corps Systems Command, the U.S. Army Aviation and Troop Command, the U.S. Naval Sea Systems Command and the U.S. Air Force Material Command signed a Memorandum of Agreement establishing the JSLIST Program. The program combined development and testing efforts resulting in the procurement of a single U.S. military CBR Garment at a significantly reduced cost.

The U.S. Army Natick Soldier Systems Center is participating in the management, design and development of the next generation chemical/biological protective clothing system. Key requirements of the JSLIST program included protection against chemical/biological agents, a lighter weight, more flexible garment, and the ability to be laundered. Key requirements of the footwear include combined environmental and CB protection, POL resistance, and self flame extinguishing characteristics.

In addition, the system is required to be durable, designed to take into account the human factors of (and acceptability to) the user, and reduce the heat stress associated with protective gear.

Description:

Components include an Overgarment to be worn over the Battle Dress Uniform (BDU), and the Multipurpose Rain/Snow/CB Overboot (MULO). These items allow complete MOPP and heat stress management flexibility while tailoring the protection levels relative to mission scenarios and threat.

JSLIST consolidates service programs to develop next generation chemical/biological protective clothing systems into common goal objectives: obtain the best suit possible at the least cost; minimize types of suits in service; maximize economies of scale; and conserve service resources.

JSLIST created an avenue for new, potential candidate chemical protective material technologies/prototype ensembles to be evaluated for technical merit and performance. This process screened potential technologies for inclusion into future advanced development programs.

Procurement of these items began in FY97.

The focus of Joint Service Lightweight Integrated Suit Technology Pre-Planned Product Improvement (JSLIST P3I) is to leverage Industry for mature fabric technologies for use in garments. The existing JSLIST design will be used as the baseline, with minimum modification as necessary for improvement. Mature fabric technologies and designs for gloves and socks will be sought as well to address the glove and sock requirements that were not met in JSLIST.

A market survey was conducted in FY97. Materials received from responding forms are currently being evaluated. Material screening is scheduled to be completed in 4FQ98. Field evaluation is projected to start 1QFY99, and technology insertion in 1QFY00.

Description:

The JSLIST P3I is a follow-on to the existing JSLIST program which developed a joint service chemical protective ensemble. It will address the JSLIST objectives (i.e. desired) requirements and those that were not met. This joint program will include full participation by the US Air Force, Army, Marine Corps, and Navy.
