The Javelin Missile Launcher, designed by Raytheon, was spec'd for engagement distances farther than was is being achieved.
I designed the tripod mount below for the Infantry Weapons and Anti-Armor Team of the Marines to increase the stability and therefore possible engagement distance of the launcher.

The rear support is necessary, but experiences minimal load. Being that it's essentially a cantilevered beam, I originally designed it to be a sheet of water jet cut quasi-isotropic carbon fiber plate.
FEA validation showed that with a minimal increase in thickness, 6061 was sufficient to handle any expected load cases

For the main load-bearing component, I originally experimented with an iso-grid pattern for weight relief but found the improvements did not justify the additional machining complexity.
