BACK TO THE DRAWING BOARD
Originally the outer breakwater of Dubai’s Palm Jumeirah Island was designed as a continu- ous barrier. But this prevented natural tidal movement, and the seawater within the crescent breakwater became stagnant. A 2009 retrofit created gaps on the sides of the breakwater, connected by bridges, that allowed tidal movement to oxygenate the water and prevent stag- nation. (SOURCE: Getty Images)
mounted a gimbaled seeker contraption on the skids of a helicop- ter and flew a simulated path to determine whether there were enough degrees of freedom for the seeker’s movement.
It might have been an extra expenditure of funds not anticipated. But it was the best approach before having a finished missile to integrate, allowing the project team to go forward with design of other components.
And during the downrange initial operational test of the Army Tactical Missile System, when the very first of only 15 missiles to be fired didn’t hit the target and was scored a failure, it was our
“hardware-in-the-loop” software model back at Redstone Arsenal, Alabama, that told us it flew right where it was supposed to—but had the wrong targeting data for the gunners to input.
History is replete with examples of people who failed to adequately model before they began construction, including the Tacoma
Narrows Bridge collapse of 1940 (unexpectedly swaying wildly in the wind and recorded on film), and the retrofitting of Dubai’s Palm Jumeirah Island in 2009, with breakwater crescent open- ings (a bit of an afterthought) to prevent internal water stagnation. Te problem is no different with weapon systems.
M&S THROUGH THE WICKETS During the materiel solutions analysis phase of the acquisition process, it’s common for PMs to invest in force-on-force model- ing to predict combat value using key performance parameters of the new system. Other concept studies include such model- ing to aid the analysis of alternatives effort.
Later on, during technology maturation and risk reduction, our prototypes will be early design models to demonstrate technol- ogy readiness levels and reduce risk by means of technical and operational discoveries during simulations. M&S efforts during both of these phases inform us as well as the user community.
