Software assessment program clues shipbuilders to threats, targets
By Dawn S. Onley
Editor
The Navy’s DDG-1000 destroyers and Littoral Combat Ships are being designed using a software tool that analyzes the biggest threats facing those ships and advises program officials to plan accordingly.
Under a contract with the Naval Sea Systems
Command, the Measure of Total Integrated
System Survivability (MOTISS) software
program, developed by Alion Science
and Technology, is providing susceptibility,
vulnerability and recoverability analysis to
the Navy during the ships’ design phases.
The MOTISS software examines infrared,
radar, acoustic and magnetic signatures
in determining likely threat distributions
and weapon strike locations. MOTISS
also evaluates the probability of system deactivation,
fire or flooding containment and
the root cause of failure for each shipboard
system.
“This is a tool that you use in the design
phase,” said retired Navy Vice Adm. Scott
Fry, senior vice president and manager at
Alion Science and Technology’s Engineering
and Integration Solutions Sector. “It’s
not something that you take to sea with you
and plug into a computer that’s going to give
you rapid answers.”
“Our intent was to develop a tool that addressed
survivability issues; specifically,
what’s the risk of being hit, what damage can
be expected, will the ship be able to recover
and what can be done within the budget
to make it better,” Fry added.
