10 May WHY DO YOU THINK IT IS COMMON FOR DEFENSE CONTRACTORS TO ADD NEW FEATURES AND MODIFICATIONS TO CURRENT PROGRAMS?
The Spanish Navy Pays Nearly $3 Billion for a Submarine That Will Sink Like a Stone In 2003 shipbuilders at Navantia Spain’s state owner shipyard welcomed a contract from their navy to construct four state-of-the-art submarines. The S-80 class was going to be an engineering marvel filled with the latest and most cutting-edge technology including a diesel-electric propulsion system that would be 20% lighter than other ships while delivering 50% more power. As the list of upgrades and new technical gadgetry grew the delivery date for the Isaac Peral—the lead ship in the S-80 class—continued to ship further behind schedule. Nevertheless it wasn’t the continuous upgradingand addition of new equipment that finally slammed the brakes on the project; it was the startling warning from Navantia’s engineers that the Isaac Peral was not seaworthy. The submarine named in honor of the Spanish man credited by some as the inventor of the underwater vessel was 75-100 tons overweight an excess that could make it difficult or impossible for the submarine to surface after submerging. As a result the Spanish navy was faced with the challenge of fixing a submarine that ran the risk of disaster whenever it decided to submerge! Navantia admitted the existence of “deviations related to the balance of weight” in the vessel and estimated it would take up to two years more to correct the problem pushing the new delivery date to late 2018. The firm’s engineers are trying to determine their best options at this point. It appears that two choices are most likely: Find a way to trim the design of the overall ship which would be very difficult at this stage in construction or lengthen the hull of the already 233-foot submarine to compensate for the extra weight. The problem with this option is that designers have estimated that for every meter the hull is lengthened it will end up costingnearly 10 million additional euros (about $14 million dollars). Unfortunately for the Spaniards independent agencies report that they have already sunk the equivalent of $680 million into the Isaac Peral and a total of $3 billion into the entire quartet of S-80 class submarines. The buoyancy problem is not the only difficulty facing the program; an analyst said that that submarine’s air-independent propulsion (AIP) system reactor is also under performing. A Strategic Studies Group spokesperson said that the AIP system has been designed to enable the submarine to operate underway for 28 days but is currently able to manage only one week. The Group’s memo suggests “The buoyancy problem alone could cost up to half a billion euros to cover redesign and extra construction without considering the propulsion problem.” The submarine setback couldn’t have come at a worse time for Prime Minister Mariano Rajoy who was already caught up in a corruption scandal and saw his approval rating hit a record low in 2013. Because of the poor shape of Spain’s economy Rajoy’s austerity cuts trimmed the Spanish military budget by 30 percent in 2012 leaving much less room for added ballast. With reports that the S-80 program will be delayed an estimated two years and another general election looming in 2015 Rajoy likely will not see the submarines through to successfullaunch.How did such an expensive project get funded at a time when the Spanish military’s entire special weapons program received a 98% cut? Sheer pride seems tohave been a factor: Spain hoped the S-80 class would be a new homegrown breakthrough achieved without foreign help. Now that Navantia has entered into a $15 million contract with the Electric Boat Division of America’s General Dynamics to help with the redesign that dream seems dead in the water.Questions1. Google “Spain’s S-80 class submarine” and read some of the articles posted. In your opinion how does technical risk cause problems with major defense projects?2. Why do you think it is common for defense contractors to add new features and modifications to current programs? In other words why do defense agencies contract for one project only to see it often evolve into something new by the time it is launched?3. If you were an advisor brought in by the Spanish government what advice would you offer
