The advanced lateral support system (LSS) is a remotely operated, controllable suspension system that uses smart materials to protect the payload (missile canister) from shock and vibration events, while having the capability of aligning it within the missile tube. LSS is designed for underwater launched weapon systems, such as the Ohio class SSGN configuration. However, this system can also be utilized for other applications where adaptable vibration and shock control is vital. The LSS reduces canister installation/removal time, increases available area within missile tube, and broadens the range of payload configurations. A subscale LSS has been developed and tested, which demonstrates enhanced shock and vibration mitigation.
