US Submarines Lost 15,000 Days To Maintenance Delays Costing 3.4 Billion

The money was not lost to fraud or overruns — it was spent exactly as appropriated on fully crewed submarines that could not sail because there was no dry dock available. GAO's 2 recommendations target the cheap, tractable half; the Navy concurred verbally and filed no written comments, and both remain open.

The money was not lost to fraud or overruns — it was spent exactly as appropriated on fully crewed submarines that could not sail because there was no dry dock available. GAO's 2 recommendations target the cheap, tractable half; the Navy concurred verbally and filed no written comments, and both remain open.

GAO found U.S. attack submarines lost more than 15,000 operational days to maintenance delays and idle time over a decade, at an estimated $3.4 billion for boats and crews that produced no operational capability.

Why it matters: About $3.4 billion already spent, roughly $10 per American, on capability that did not exist — and a further $3.1 billion projected through 2030 that has not been spent yet.

Date to watch: Whether either GAO recommendation moves from open to closed on GAO's public tracker
