Venezuela decided to negotiate with Russia a loan of about $800 million for the acquisition of 4 diesel Project 636 Kilo class submarines. During that time Venezuela was also considering the purchase of 12 Il-76 transport aircraft. The submarines plus the aircraft were going to cost a total of $1.5 billion. However, this acquisition deal wasn't completed either. The negotiations for the purchase of the submarines broke down and 6 submarines that were once planned for Venezuela are now being offered to Vietnam.
