Submarine Team One (ST1), a cross-organizational group charged with providing permanent improvement in cost savings and performance to submarine depot availabilities, is currently focusing on the removal of hull-coating tiles in submarine sails. “Our concern with the tiles in the sail is the corrosion that occurs behind them,” said Capt. A.J. Mullarky, SEA 07's Program Manager for Strategic and Attack Submarines. Removal of the tiles will reduce the cost of depot availabilities and reduce the total weight of the ship. ST1 estimates that by removing the tiles, 55 mandays and $22 thousand in materials will be saved during each major depot availability (MDA), which conservatively translates into a total savings of around $75 thousand per MDA.
