Also, boats are modified, sometimes extensively, while in service, creating departures from the class standard. Minor variations occur as improvements are incorporated into the design, so later boats of a class may be more capable than earlier. Scott Pappano, program executive officer for strategic submarines, said at an event hosted by the Advanced Nuclear Weapons Alliance Deterrence Center in May.Submarines of the United States Navy are built in classes, using a single design for a number of boats. "We're doing evaluations right now on what it would take to do a short repair availability - short-ish repair availability - to extend those ships for a couple of years as a risk mitigator, if need be," Rear Adm. Cost overruns and delays in major Navy acquisition programs are not uncommon, and the Navy is now thinking about extending the lives of up to five Ohio SSBNs in case its new subs run into trouble. That is a tight timeframe, especially considering the importance of SSBNs in the US's nuclear posture. The Ohios, all but five of which have been in service for 30 years or longer, are expected to be decommissioned between 20.
