![]() ![]() And these fixes require highly Partly this is because setting the right reactor conditions to make the repairs in places that were never supposed to be accessed takes time. The fittings around the pipes, as well as the pipes themselves, were designed to t for 35 years or more, adding to the expense and difficulty of the repairs. For this reason, these parts were built designed to last 35 years or beyond, the full life of the submarine. The reactor must go through a lengthy process to set the right conditions before a repair worker can enter the compartment, which was designed never to be refueled. Two sources familiar with the repairs said The repairs to Minnesota are were time-consuming and expensive, according to two sources familiar with the work. The Navy would similarly not comment on how long the required repairs for John Warner or North Dakota would take, how much they would cost or who was paying for them. Attack submarines, which are always in high demand, will continue to be deployed when and where they are needed most." ![]() "Leaders regularly review operational schedules and adjust them based on force availability and presence requirements. "Generally speaking, delays in maintenance periods will impact the overall operational availability of the submarine force," Lt. Tim Hawkins acknowledged that maintenance delays do impact operations. In a statement, however, Navy spokesman Lt. ![]() A Navy spokesman declined to say how much the The Navy would not comment on what specific impact Minnesota’s delays were having, nor would they comment on the projected cost overruns for the Minnesota’s extra year in the shipyards or who would be paying for them. The Navy spokesman acknowledged that maintenance delays affect what ships are sent on deployment, but declined to go into any specifics about how other crews were and how they could be affected. Spokespeople for the Navy and NAVSEA declined to provide an estimated cost for Minnesota's extra year in the shipyards or to say how much it will likely cost to fix the John Warner and North Dakota. A retired submarine engineering officer who spoke to Navy Times on background to protect business ties. If the fittings failed, the results wouldn't be catastrophic but the ship couldn't operate normally until it was fixed, according to three sources familiar with the repairs. The fittings are part of the ship's main steam system, which takes steam from the reactor compartment to the propulsion turbines and generators. The culprit: shoddily constructed and improperly certified pipe fittings, welded into a part of the state-of-the-art propulsion system that was never supposed to be accessed. which will both need to have them replaced, significantly increasing the workload and cost for their post-shakedown overhauls. If these pipes ruptured, they would leak steam and force the submarine to take emergency measures that would impair everely reduce its combat effectiveness. The same shoddy elbow joints fittings were installed aboard attack subs in both the attack submarine North Dakota and John Warner, forcing the Navy to spend millions of dollars and many more months to repair them. ![]()
