In the end, however, technical, reliability, and cost issues have proven nearly insuperable. Indeed, the ASDS has been cancelled for all intents and purposes; all that's left is an ASDS-1 improvement program to boost the performance of the existing sub and complete its operational testing. The Richmond Times-Dispatch notes that the ASDS mini-subs were originally supposed to cost $80 million each, but numerous problems with the first boat have ballooned its cost to $446 million so far (vendor and government facility costs inclusive). Instead of completing integration and entering service in 2000, testing continued and the first boat was officially delivered in July 2003. GlobalSecurity adds that the program was initially projected to cost $527 million (including delivery of all six boats), but it is now predicted to rise to more than $2 billion – significantly more than the $1.4 billion SSGN Tactical Trident conversion program to which it is related.
