A lawsuit seeks to hold General Dynamics responsible for an explosion that killed one solider and seriously injured three others during an Army training exercise in Hawaii in 2006. Staff Sgt. Oscar Rodriguez was supervising the firing of mortars when a shell prematurely detonated, killing him and wounding Samuel Oyola-Perez, Julius Riggins, and Wilfredo Dayandante. The lawsuit claims that the mortar cartridge, manufactured by General Dynamics corporate predecessor-in-interest Martin Marietta Aluminum Sales, was defective and did not comply with the design and specifications issued by the government. In 2010, a jury found in favor of General Dynamics, but in 2013 an appellate court reversed the verdict and ordered a new trial.
