After indepth testing of the remaining systems and observations of the systems in action, the German STN Atlas ISUS 90-55 aboard an Israeli Dolphin-class submarine and the American Raytheon CCS Mk2 aboard a USN Los Angeles-class submarine, it was decided that the STN Atlas system was the best for the class. However, political pressure from both the United States and Australia, questions about the security problems and possible leaks involved with a European combat system linked to American weapons, and desires to increase the political and military ties between Australia and the United States resulted in the cancellation of the tender program in July 2001 and the decision to enter a joint development program with the United States, with a formal agreement signed on 10 September 2001 at the Pentagon. The second combat system development program proceeded with far fewer problems, and took the tactical and fire control components from the CCS Mk2 system, and the sonar interface component from the fast track program. The system is the AN/BYG-1 that was developed for the new USN Virginia-class submarine and has since be retrofitted to the whole USN fleet. The new combat system was installed in Waller in 2008, Farncomb in 2009, Dechaineux in 2010, Sheean in 2012, Rankin in 2014 and Collins is scheduled for 2018. The system can receive new software releases and hardware can be upgraded with new versions of the system regularly released with the version operated by a boat dependent on its fully cycle docking schedule. Budget Several newspaper articles and commentators have incorrectly claimed that the project ran significantly over the contract cost. As of the launch of the first submarine, the project cost had increased from A$3.892 billion in 1986 dollars to A$4.989 billion in 1993 dollars, which corresponded to the rate of inflation during that period. By 2006, A$5.071 billion had been spent to build the submarines (excluding the fast track program); after taking inflation into account, the project had run less than A$40 million over contract. Of the A$1.17 billion allocated to the fast track program, only A$143 million was required to fix problems where the submarines did not correspond with the original contract: the rest was used to update components that were technologically obsolete and make changes to the submarines beyond the contract specifications. When the fast track program is factored in, the Collins class cost just under 20% more than
