The Navy has axed the Advanced Seal Delivery System (ASDS). After a fire last November caused over $200M in damage, the Navy decided to go ahead and kill the ASDS and not even repair the one delivered. I think over $1B had been spent already on this thing, and it just wasn't working out.
What also wasn't working out was who was going to pay for it and that was always a problem.
According to the Honolulu Advertiser, "Funding has been requested for the Joint Multi-Mission Submersible program to develop an alternate SEAL insertion craft. The online publication Inside the Navy reported in June that $43.4 million was being sought for pre-design work for the mini-sub that would provide 'improved performance' over ASDS."
This supposedly is in the 2010 budget.
So, the SEALS will remain wet for now.
