W88 Alt 370 Tested (IMAGE) DOE/Sandia National Laboratories Caption Sandia National Laboratories performed a drop test for the W88 Alt 370 system, designed to replicate a crane accidentally dropping the re-entry body onto a concrete surface. The test was conducted at Sandia’s 185-foot Drop Tower Facility, using the same handling gear a crane would use to move the weapon.
