delivery of several submarines being built at Electric Boat's shipyard. In some cases, the repairs resulted in practically dismantling and then rebuilding what had been a nearly completed submarine. The yard tried to pass the vast cost overruns directly on to the Navy, while Admiral Hyman G. Rickover demanded from Electric Boat's general manager P. Takis Veliotis that the yard make good on its "shoddy" workmanship. The Navy eventually settled with General Dynamics in 1981, paying out $634 million of $843 million in Los Angeles-class submarines cost-overrun and reconstruction claims. As it happened, the Navy was also the yard's insurer, liable to compensate the company for losses and other mishaps. The concept of reimbursing General Dynamics under these conditions was initially considered "preposterous," in the words of Secretary of the Navy John Lehman, but the eventual legal basis of General Dynamics' reimbursement claims to the Navy for the company's poor workmanship included insurance compensation. Veliotis was subsequently indicted by a federal grand jury under racketeering and fraud charges in 1983 for demanding $1.3 million in kickbacks from a subcontractor. He escaped into exile and a life of luxury in his native Greece, where he remained a fugitive from U.S. justice.
